Title: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on August 13, 2016, 12:25:35 PM
Here's the XB1s controller, which has a few changes done to her. It's still a CG layout, but they have ditched one of the board to board connectors and used a 16bit I2C IO Port Expander for most of the Digital functions now. That has the benefit of only needing 3 connections, instead of the 13 that it did before, so they can use just 1 connector. There is also a cable for an on board RF antenna that goes to the MCU/RF board.

The MCU board has some changes as well. The Triggers are still the Hall sensor type, but the MCU and RF module have been combined into a single PCB that is mounted to the main board. The MCU/RF board also has it's own antenna.

NOTE: The MCU board and SOC board are technically 1 unit, but they will have separate schematics here. The MCU board is the larger one that has the Sticks on it. The SOC board is the smaller one that is soldered onto the MCU board, but is in fact the MCU board because the MCU is on it. I know, it makes about as much sense as a picture of flowers, just deal with it. ;)

* Information will be updated when/if I get them scoped and/or figured out.


IO EXPANDER (U4 on Power Board, PCAL6416A)

Any familiar with the I2C protocol will recognize this. It's the Clock and Data to/from the IO Expander, and it's sampled every 8ms or at 124Hz, which is over 120 times per second, so it's not going to miss a button press made by any human. It first sends a Write Command 0x42, followed by the Data 0x00, then it sends a Read Command 0x43, which is followed by all of the buttons and PnC cable status. 1 for off, 0 for on. Data is sent MSB first in two 8 bit configurations, with 3 of the 16 IO not being used.

(https://www.acidmods.com/RDC/XB1/No%20Press.jpg)

The order of bits 76543210 76543210 correspond to the buttons, MN, NU (FT4), LB, RB, Y, PnC, X, NU (Grounded), A, NU (TP26), VW, DD, DL, DR, DU, SY

NU = Not Used, reads as 1

This is with no buttons pressed, only the PnC cable is plugged in. So you'd get 11111010 then 11111111 after the Read Command, or 0xFA then 0xFF

(https://www.acidmods.com/RDC/XB1/Not%20Pressed.jpg)

Here A, X and Y are pressed. along with the PnC cable still plugged in. So you'd get 11110000 then 01111111, or  0xF0 then 0x7F

Interesting that they've decided to go for an SoC type module, and removed one of the two board-to-board connectors.

Hi, I'm trying to solder a button on TP21 which is supposed to be A but does nothing. I have put a cable to TP22 to make ground and another cable to TP21 for the A and
does nothing.

Edit: I already found the correct TP21, I mistakenly connected it to the TP21 that is next to the TP9 and it has to be soldered in the TP21 that is next to the TP27 of the other PCB

regards

That's why the TP spots are listed under the corresponding header of TEST POINTS on BUTTON/POWER Board or TEST POINTS on MCU Board, as both can have the same number TP spot, but it doesn't do the same thing.

hello, I also have the saleae Logic Pro. Great analyzer.

i have a question for you. do you know how to power up the 1708 or 1697 externally? when i ground the GU line, it will power down, but I cant seem to get it to power up using the same line.


Thanks in advance.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on January 26, 2017, 11:46:28 PM
Not sure what you're trying to do there or how. The USB cable is an external power source, and it should work fine.

If you have the Button/Power board removed, then that's the issue and you can read thru the 1537 thread for info on what to try there powering it with that removed.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: troyvolta on January 27, 2017, 11:22:49 AM
sorry, I don't think I explained myself very well. I want to externally power up a stock 1708 or 1697 controller using another microprocessors I/O line as opposed to pressing the guide button manually.  I want to run the wires out of the controller to another micro.  I could just directly connect across the Guide button, but the guide buttons location is hard to wire up. So I was wondering if you knew of a different spot on the controller that would mimic a manual press of the guide button to power it up.

Thanks.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on January 27, 2017, 12:41:42 PM
Gotcha. You can't ground the GU pin of the connector and have that work, as there is a Diode on the board that is giving you the grief there. Use the Cathode side of D27 for your GU connection as that goes directly to the Guide button. This is the same on all versions so far.

Adding A and B back buttons. I did this using scans of the old One controller but I have a 1708. I just want to make sure I use the right solder points. From what I see I can use TP21 on the BUTTON/POWER Board for A, but I don't know what Ground to use. Then I can use TP41 on MCU Board and TP22 or TP26 for Ground. Am I reading this wrong? Is that not where I need to solder to add new buttons? Any help is very appreciated.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on April 11, 2017, 04:06:45 PM
Those are the correct TP spots to use for the 1708, and ground is ground, so you can use any ground you like for the buttons.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: grokshot on April 11, 2017, 04:51:55 PM
So all I need to do is solder to those TP spots and any ground? Just really want to make sure I didn't need to solder anywhere else and that those were the right contact points to add the scuf-like buttons.

Unfortunately my soldering iron was just too much and killed the test point for one of them. TP21. So now the normal B button doesn't work either. Not sure why it was harder on this one than the older version. The new A button didn't work either but the old one still does. I wonder if the ground has to be on the same board for that one.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on April 11, 2017, 05:32:46 PM
The soldering iron is fine, it's how you're using it. If it ended up hot enough to torch the pad off the board, then it was long past melting the solder and being done.

TP21 is for A

The TP41 is in the middle of the B button trace, so if it was nuked off the board then B would be dead. You'll have prep both vias at each end of that trace now and jumper it with a wire to get B working again. Don't torch those though or fixing B will be more of a hassle.

Ground is ground, doesn't matter which board it comes from.

Sorry, I miswrote with the TP numbers. I am not sure how to jumper for B. I may just have to buy a new board and be more careful next time. Thank you for all the help.

What wattage iron should I use?

Post by: RDC on May 19, 2017, 05:58:47 AM
@ grokshot - Soldering iron wattage depends more on skill level than anything, though there is no point using a 200W gun on the controller. I use a 60W Hakko here for almost everything that I do, but all you really need for messing around with controllers is a 25W or so at most.


@ leonmax81 - The TP spots for this controller are listed in the first post.

You have pin 1 of the PIC connected to pin 3 of J5, not pin 4.

Pin 4 of J5 is on the other side of the connector. Odds are on one side, evens are on the other. Whoever made that messed that up. Just use TP35 on the Button/Power board for you 3.3v power to Pin 1 of the PIC.

That may or may not fix it, as I'm sure the code was written based on the ADC having a 3.3v source, not 3v to whatever the battery voltage is, which is what is on pin 3 there. Change that to either pin 4 or TP35 and see how it works then.

Post by: RDC on May 19, 2017, 10:54:37 AM
Unless you have another older version controller to test that PIC on and make sure it works, no idea. The controller hasn't changed how it works, so you'll need to get the person that coded it to look into it.

Hey RDC,

Any chance you know what the values are of the capacitors on these boards?

I've got a duff controller here which isn't powering on off either batteries or usb. Noticed after having it plugged in that the dpad was starting to get toasty.

Looking at other stuff online indicates that on the older models it's the capacitor at c30 pulling the 5v to ground that is playing up. Most people seem to be able to just remove it without issue but of course it's there for a reason

Just dipping my toe back in to tinkering with broken electronics
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on August 24, 2017, 04:44:50 PM
Most of the caps are just decoupling, for filtering the DC, and the exact value isn't going to be really critical.

C30 on the 1708 version Power/Button board is a 16uF, 0805 that's probably rated at 10v or more.

Hi guys. I came in possession of 4x new controllers 1708. All have exactly the same issue: on USB cable they work perfect, but no power on battery. Nobody opened before so it seems like a common problem on these. I attempted repair and checked the (+) power line and could not find any break up to Q9. There is 3v power on the power button. I've replaced U1, U2, U3 but problem still not solved. I've spend hours searching for missing or blown components on the board and could not find any visible damage. Please help me solve this? It's honestly killing me and as usual the solution is just around the corner..... thank you. :beg: The power board is the issue.

Post by: RDC on November 20, 2017, 02:28:04 PM
No power with the PnC battery pack? New AA batteries? or both are a no go?

Have you confirmed the Power board is the issue by replacing it with one from a know working 1708 controller?

My 1708 board is stripped clean, or I'd start poking around in there looking for that problem. Right now all I can do is schematic it out and give you some ideas on where to look.

I'll have to trace out the 1708 and see if they did anything different, but on the 1537 Q9 gets the power good signal from the MCU board thru D26. If D26 was open you'd have issues, but not sure as of yet if it would effect the USB power.

Q7 is the first place I'd start though, provided a know working board powers up with batteries fine so the issue is for sure known to be on the Power board.

Hi RDC. Thank's for a quick reply.
I use just regular batteries for testing, the Duracell ones that came with controllers. I confirm that batteries are not the problem.

Yes, I confirm that the issue is the power board, all MCU boards are perfect with a working powerboard.

D26 replaced but still not working.

I was reading the forum for solutions and fount that the pin 4 on J1 should have 3V. What happens is: when I push the power button 3V appears on pin 4 for a few seconds and the soooowly drops down.

I lost a lot of time and hope trying to repair this and I will try any ideas that would come to your mind.
Thank you

Post by: RDC on November 21, 2017, 08:07:02 AM
What have you replaced U1, U2 and U3 with?

Pin 4 of J1 should have 3.3v on it, as it's the output of U3 and that one powers just about everything. That's on a working controller of course.

U2 just provides the 3.5v for the Rumble motors, and U1 is only in there to knock down the USB 5v to around 3v.

Make sure L4 is on the board, and if it is, make sure that it's not cracked, has one side not soldered or measures open.

Now that I'm thinking on it, the issue could be that U4 has crapped the bed also and is loading down or almost shorting the 3.3v rail. Take one of those boards and just remove U3 and see if it will power up normally then.

Does anyone know the exact MCU type? I know it was an MKL26 with 256KB before, but is it still?
I guess they have at least increased the size - since they added BT?

For everyone that follows: No it isn't! It's an Mediatek ARM MCU now. It is called "Microsoft ARM X905893-002" but unfortunately there is no Datasheet available.

@RDC: Do you know what the (missing) J1 connector on the MCU board is good for?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on March 21, 2018, 03:56:42 PM
It could still be one of the ARM chips that are currently out, or it could be they had it made for them. You could pull one, count the pins and layout, then reverse the entire board to see what pins are connected to what, then go thru every ARM chip that is close, but that's a real pile of work and only a 50/50 shot at the very best to finding it, been there done that before.

I haven't torn down the 1708 to trace where that J1 goes. It could be the JTAG header or just some debug port.

I tossed the Saleae Logic Analyzer on it and there's just a spit of what could be some data after power up and then nothing else. I see no CLK signal, so the JTAG header seems unlikely, but it could be the thing is setup to need some input on J1 or even some button combination to switch it on. You'd have to trace the entire thing out to see where each of those lines go to even start guessing there at what it's purpose might even be.

Hi,
i have a problem with lot of controllers.
First it dosen't power up from USB or battery and the main board at the U1 heats so up it melts the plastic befor it.

What can be the solution for this? I hope not that i have to replace the whole panel...

U1 is bad for starters, it's an MP2161. The traces and board may be damaged to the point that replacing it isn't wroth it. You'll have to carefully remove U1 there and see the extent of the damage first.

I have a new intersting found out. The S controller not power on from USB until the antena cabel is connected. If it's connected the U3 is getting realy hot.
I have changed the U3 from an old panel and the problem stil exists....
If the antena is not connected then the board turns on and the U3 is not getting hot.


Any idea?

The Antenna has noting at all to do with the controller power, other than the shielding for it being another ground connection.

Post good pics of the boards, top and bottom, as well as close ups of the damaged area and repair work, because that problem makes no sense at all.

So let me take what i know.
I have a board where it not goes on USB when the antena is on. Your right the antenna is a GND when its on the board but when you move it from then 3,3V is on the point.

when i conect it by hand in the bad panel it shuts down all. But when i change it with a working panel it dosen't go of. So i think the problem is under the chip which has an metal on it. Hope i write it understandable:D

There should be no 3.3v on the antenna unless it is plugged in, and even then it is not a 3.3v power source.

I have no idea what 'panel' you are referring to. If you mean that it works fine with another MCU board, then it will be difficult to track down the problem without comparing the two so you can find the fault.

Okey, i have changed the U1/ U2 / U3 for new ones. And find out that the problem is something else. I think the problem is the big "chip" where you connenct the antena on the board where are the analogs are. Because whe i cange for a new board then everything is okey.
It's an 1626 board. Have any one some idea?

Check the MCU board alone and see if the 3.3v rail is shorted to ground, J5 pin 4 is 3.3v. If it is shorted, remove C7 and test again. If the short is gone, replace C7 with a 100uF, 0805, 6.3v or higher and try it.

I'm struggling to identify some components. Can anyone help?

Firstly D23 / D22 (and D14) which appear to be top marked D2 or O2. I've read on here they are Schottky type and appear to be SOD323 package. I'd hazard a guess they must be rated for 6V or more and capable of handling 1A or more (MP2161 maxes out at 3.5A but the USB on the console only outputs 500ma?)?  (D2 / D25 / D27 I can identify as 1N4148WS which have A2 or T4 marking)

Secondly the EG components - specifically EG1 on the MCH board. I have a missing EG1 on a board which I suspect is why there's no audio on the headphone socket.

Many thanks in advance :)

I have removed the C7 and the ESR value is good, and stil not powering on. Have checked a working panel, had removed the C7 and still works.
So still no clue for this probleme. Only works when i remove the antena but this way the PC from bluetooth not recognize it.

Post by: RDC on May 09, 2018, 12:23:35 PM
@ lukasz - Q9 is just a simple NPN Transistor. The MMBT3904 should work fine there.


@ MattP79 - The D23 and like are just a Schottky type, and 1A should be fine for them. The EG components are some type of TVS diode or MOV. It should work without them, unless it's torn up the pad/trace. Best place for a replacement part there would be another controller board so the value is correct.


@ FlexBitt - You'll have to just start doing comparing on that dead board to a know good one to try and narrow it down. It could be the RF portion of the circuit or the chip is bad sending VCC out on the antennae line so when it's plugged up it shorts. I haven't seen or heard of that issue before.

U4 is an IO Expander, PCAL6416A made by NXP, you can Google up the DataSheet for it's pinout. 

Can you tell if the B, LSC and RSC buttons still work normally? They're not part of that IO expander chip and should still be working.

There could be no power getting to U4, or it could be bad. There might be some issue with the I2C lines, and you'll really need a scope, or better a Logic Analyzer, to see if those are doing what they should be or not.

Thank you very much for your answer. The B, LSC and RSC buttons operate normally. After checking the buttons on the computer, I jumped out that the others are still pressed. And after connecting to the Xbox, something is always selected and the picture jumps.

All of those buttons are on the top board, so the very first thing that I would do is try a whole other top board from a know working controller. Then if that worked, I would look at the SDA and SCL lines of the bad board with a Logic Analyzer to see what is going on there, then I'd replace U4 on the top board and see if that corrected it.

Then you need to put a LA on it and see what is going on, because U4 is the only thing on there that reads those buttons. It may not be getting power, might have some cracked trace on the board or short on the data/clock line, but it's something that is affecting U4 there.

All of them have the traces right on the bottom of the board at the POTs. Cut them there, then just rewire solder joint to TP spot. Have fun with that though, as you'll end up with every axis off from where it used to be and worst case some that will be drifting and then need tweaked.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"

I thought about the drifting issue. I am planning on removing the pots and physically swapping them, then do the southpaw mod.


EDIT: Physically swapping the POT's should work, unless the heat from the soldering iron changes the characteristics of the POT..


Thanks for the information.

That's not going to keep it from having an issue. That's like saying you're going to put your drag cars big fat rear wheels on the front and the skinny ones on the back and it'll be fine because you're only going to drive in reverse.

The controller is calibrated with the Sticks in it how they are now, just swapping the POTs will still throw it off because they have a tolerance of their own, just as the mechanical parts of the Stick housing have tolerances, and they are not all 100% the same. Moving anything related to the Sticks around anywhere will toss it off a little bit, how much depends on how far off they are from each other, but again, swapping the POTs will not get you 'out of jail' there and in fact, it could make it worse.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: SharkyJC on October 16, 2018, 09:55:33 AM
I am going to desolder the entire assembly, and move both sticks, then cut traces, and solder from x,y to TP's on the PCB.. Electrically, the pots will be attached to the same inputs but wired in southpaw configuration. If I cut the traces and wired up for southpaw without moving the pots, I can understand that would introduce drift.

I'll perform the mod and let you know how it turns out.



Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on October 16, 2018, 05:14:45 PM
Simply removing the entire stick assembly, and then reinstalling it right back where you just removed it from, will still throw it off a bit. You're not going to get around the fact that messing with it in any way, shape or form will toss it at least a little out of wack from where it was originally calibrated at. How far off it'll get depends, and you may not notice it in most games, but put an app on there that shows where it knows dead center is supped to be, a Cronus or the like, and you'll see it's off after moving any of that stuff around in there. This isn't RDC's first rodeo. ;)

It is better to use a Resistor, but not required, and even if you blow the Hall sensor up it can be replaced. They are the A1304ELHLK-T, with a sensitivity of 4 mV/Gs.
(NOTE: If you want a bit more sensitive Trigger, but not a hair Trigger like a Tact switch would provide, then the A1319LLHLT-5-T can be used, as it’s sensitivity is 5 mV/Gs)

The are repairable, though the amount of time you will spend on them and how useful they will be afterward will not be worth it compared to just finding a couple of replacement boards and having a fully functional controller again that you can still take apart without being afraid all of that tedious work you did will come with it.

You can find those boards for less than $20 each, and then keep the old ones for parts. That's how I'd go about 'repairing' those controllers, unless I had nothing better to do and felt like just seeing if I could repair them, but I've already been there and done that on enough PCBs to know that I'd just replace those things and then use those for parts.

I have no solder on my tp21, and when I try to attach the power wire from my 30 mod chip it won't make a connection. Is there any way to correct this? Or can I just use a other tp location for power.

TP21 on the top board is the A button, if that's torn up you have a problem.

TP21 on the bottom board is just Ground, any ground spot can be used for that.

Post a good pic of the spot you are having an issue with.

No idea what instructions you're looking at, or how they looked at it, but there are only 3 TP spots there, TP54, TP21 and TP9, and TP21 is right there in the middle and it's just ground.

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on December 03, 2018, 06:04:04 PM
The copper pad is gone, you'd never get a wire to solder there. You're just soldering right onto the bare fiberglass of the PCB there.

Move up to the spot just above TP9 there on the SOIC board (the little board that's soldered to the main board) and where it's marked *31 on there, the bottom right solder joint (can see it in your pic) and solder your power wire there. It's the same as TP9, just be careful and do not bridge that spot to the one just to the left of it, as that one is ground and you'd short the 3.3v rail of the controller if that happened.

Hey,

Amazing job with the PCB schematics.


I have a controller to repair, Basically the controller stays on as long as you hold the Xbox button, but as soon as you let go of it, it looses power.

Same story the issue happens on batteries only once you use external power to USB it works fine, I tried to see if any cap is broken however I was unable to find anything.

Any idea?

Unplug the Button/Power board and do some Resistance measurements.

Check R4 and R7, both should measure 0ohms.

Measure pin 9 of J1 to Ground, should be around 2M (1.5M to 3M is fine).

Make sure D26 is on the board.

Check R25, it's 25.5k and R26, it's 0ohms.

You can just toss a small wire in there, or even solder bridge it to jumper R7, that's all it's doing anyway.

Hello everyone.

Recently a friend brougth me a controller with a problem similar to the one @lukasz and @FlexBitt described. All the buttons from the button/power board appeared as pressed all the time.

The voltage on those buttons was low and flickery, but the outputs of the buck-down regulators were OK and stable.

With the help of the diagrams provided by @RDC and the datasheet of U4 (which I was able to found via this thread), I isolated the problem to be that the (negated) reset pin of U4 was floating due to a deterioration of the PCB in that area. R4 was disconnected from C37 and the reset pin of U4.

A simple mini-blob of solder did the trick, and the controller functions normally now.

When you plug the controller in it's then technically a wired controller and as long as the USB has 5v then the 3.3v will be on.

There are no 3v spots in the controller for positive. You need to use a 3.3v one, like TP9, and the proper Resistor value for you LED current rating. Then use a ground spot for the negative, like TP21.

Hello everyone!

I have recently decided to try my hand at repairing xbox controllers. I have a controller whose, even after a new thumbstick module has been installed, left stick will not register any movement on the y-axis. Movement on the x-axis works perfectly. I have noticed that when i touch the three pins on the left side along the edge of the board, the y-axis corrects itself to resting position. This makes me think that there is something wrong with the circuit board itself. Any advice on how to fix this issue would be greatly appreciated.

Thanks,
Jonathan

Use a DMM and make sure there is 1.8v on one outside pin and ground on the other of the POT for the Y-axis. The center pin should measure right around 0.9v with the stick in the center position. Ohm out the center pin of the Y axis to TP63 if those all check fine.

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on April 16, 2019, 08:01:03 AM
You have to sacrifice a Thyristor to the Gods of AC to be able to see thru the smoke that's inside the electronics. ;)

There are several easier ways they can be figured out with common sense and a little work, though it seems like the aforementioned is more attainable nowadays.

Just looking at the board tells you most everything you need to know, because if there is a TP spot on a trace that does this or that, then that's TP this or TP that. Then you can Ohm out the TP spots to other known spots on the board to confirm or figure out where they go. Checking them with a DMM, Scope or Logic Analyzer while the controller is on can also be done.

@ vaxtalas - Test the bottom board with a known good top board first, make sure the top board is the one that has the problem.

After that, there could be any number of things that would cause that problem. Look for a cracked or scratched board (damaged traces), any missing components, anything that looks discolored or solder joints around the ICs to indicate they have been too hot, just any all of the obvious things first.

If the boards all look good, then you'll need to just start doing voltage checks and comparing a good one to a bad one to see what is missing form where.

Post by: micmac on June 26, 2019, 05:22:32 PM
I just wanted to thank you for this thread.
I just got a faulty controller that seemed to have most buttons pressed all the time. After testing the controller with a good button board i realized that's where the problem was and then I started measuring for continuity on the board and comparing to the good board, to see if there was a short somewhere. I couldn't find any. So I started following the traces from the buttons and wound up at U4. For a while I followed the traces from U4 to wherever they went, but without any magnification, that's hard on the eye. So I went to the PC and found this thread with all information on the board and how to find the datasheet for U4.

With this new information I went back to the board and quite quickly found the fault. The reset pin on U4 was not connected to pin 9 on J1. Measuring along the trace, I found that there seemed to be a break between U4 and C37. Obviously I did the easiest thing i could think of and carefully enlargened the hole next to the reset pin and took one strand from a cable and threaded it through the hole. Then I tried to solder the copper strand to the reset pin. Again, no magnification.
Of course i soldered it to the next pin and the capacitor right above (C28) as well, so time to remove the solder. After struggeling for a bit I got rid of the excess and turned the board over to solder that end of the strand to C37. That's when the strand fell out. Apparently it wasn't soldered to the reset pin.
So I start over with a new strand of copper wire, thread it through the hole and solder it to the reset pin. This time I make sure that it's stuck. I turn the board over and solder the other end to C37 and then i measure for continuity between the reset pin and pin 9 on J1.

BEEEEP!

My power pcb has broken at the thin part next to the right thumbstick which resulted in DU and DR not working properly so I first attempted to expose all the traces there (4 traces on one side and 1 on the other side) and then applying solder right on top of the traces in order to patch them up. I screwed this up so I ended up just filing off all the traces in this area and then solder jumper wires directly from the buttons (the via pads) to the testpads, however I'm not able to make the solder stick to the pads. Any tips here?

If you can't get solder to stick to the TP spots, then you're either using not enough heat, or far too much heat and have burnt them off the board. They already have solder on them, so it doesn't take much at all to get a wire attached to them.

Post a good pic of the damaged area and board if you can.

Post a good pic of the damaged area and board if you can.

I was able to make it stick when I scratched off a layer to expose the copper. The break is pretty much exactly at the label "LB1" shown on the first picture in the thread. It affects both sides of the board. I filed down the traces on both sides here since they seemed to interfer with each other and solder in bypass wires between the switch pads and the corresponding "test points, but now I'm not able to get DU and DL to work. When I measure the voltage on DR and DD (which are working) they show 3.3V while open. DL and DU show approx 0.3V while open, so there seems to be an issue with pullup resistors here. However when I connect the pad and run the calibration tool in windows both DL and DU show up as not activated, which is strange since they are pulled low at 0.3V.

Does anyone know the switches are configured? Are there passive low pass (RC) filters as well?

There are no PU Resistors on the button lines, all of them on that top board (except for Guide, and then Y runs thru R42 first but it's a 0ohm jumper) run directly to U4. Check the voltage for DU and DL right at the leads of U4, pins 11 and 13. If you have 3.3v there, then you still have a break somewhere in those traces. If they also measure 0.3v, then there is an issue with U4.

When only the top board is connected (USB) it won't turn on at all and I measure 0V. If I connect both boards it turns on, but then I'm not getting access to the uc in order to measure..

By the way, there are a total of 5 traces severed (four on the button side and one on the battery side), which should mean there's at least one other peripheral out of function. I'm not even sure all the D-pad buttons goes through these traces.

No idea if it will work not knowing how the chip is setup. The Sync button, as do all of the controller buttons, go to ground when pressed, so if they made the chip that way you'd only need one of those wires to possibly make that work.

There are no Resistors on the Y-axis line. A shorted Capacitor (C22) on that line would cause the Stick to go full in one direction.

If the Stick is staying roughly in the center position or just jumping all over the place, then there is most likely an open trace somewhere or an issue on the smaller castellated MCU board.

Welcome.

It's not the most difficult repair, and it's already buggered, so you can't really make it any worse by trying to fix it. Never try, never fail, but never fail never learn, and even if all you learn is you couldn't do it, that just means you couldn't do it this time. ;)

The thinner the wire you can get the easier it will be to try. A single strand from some decent speaker wire works well.

(https://www.acidmods.com/RDC/XB1/Repair/Groove%20Harder/1%20-%20Wire.jpg)


I used the bit larger wire for this example, but the thinner would have worked better. Tin the end of it up and put a drop of flux on pin 17, it's going to get elsewhere, but that's fine as it will keep the solder from bridging and causing shorts where you don't want them. Trying this without flux is possible, but it's just asking for solder bridges. Don't add any more solder to the iron tip, as what is on pin 17 and the tinned wire end are pretty much enough to do the job.

(https://www.acidmods.com/RDC/XB1/Repair/Groove%20Harder/2%20-%20Prep%20and%20Flux.jpg)


Carefully bend the wire around to avoid hitting anything it could short on and solder the other end, either to that via or the right side pad of D11 there.

(https://www.acidmods.com/RDC/XB1/Repair/Groove%20Harder/3%20-%20Solder.jpg)


Gently clean it up with some rubbing alcohol and a Q-tip, and give it a good thrice over with some decent magnification to make sure nothing is shorted and the wire is just where you want it. Then give it a drop of hot glue in the middle of the wire somewhere, never on top of the solder joint.

(https://www.acidmods.com/RDC/XB1/Repair/Groove%20Harder/4%20-%20Check.jpg)


This isn't what I'd call my best work, just did it real quick here to show how it could be done. The thinner wire and following the original trace route would have been my choice for an actual repair. You also don't need some crazy expensive or microscopic soldering iron either, this was done with my weapon of choice, the 2.4mm chisel tip, which by comparison doesn't look like the right tool for the job, but it just did it. ;)

hi. i have a problme with 1708 board.when i push y button it works but when i dont push it , it still is on

i checked y button and its all right but i think there is a problm with u4 ic

anyone can help me figure it out ?

Under what condition does the Y button become unpressed? You say you push it and it works, but it stays on, which it could not do if it stays on after it is pushed. So does the Y button 'reset' after a power cycle? remove the batteries? let it sit for a little bit?

If the actual Y button does not stick, and it takes a power cycle (controller off/on or pull the batteries) to get Y to work again, then I'd suspect U4 is latching up on that line, but I haven't seen one with that exact issue before, and in that case U4 would need to be replaced.

I have a 1708 controller that won’t detect the headset when plugged into the 3.5mm port. I’ve replaced the port with a known working one and even soldered it to PK1-PK7 to ensure it is making contact and still no headset can be detected. Any advice is appreciated!

Are you plugging in something that works on other controllers?

Any components knocked off the board around the PK contacts? R9, R10 etc. etc.

PK1 - Ring 2, GND
PK2 - Tip, LEFT
PK3 - Connects to PK2 with nothing plugged in, open when headset is plugged in
PK4 - Ring 1, RIGHT
PK5 - Open with nothing plugged in, connects to PK7 when headset is plugged in
PK6 - Shield, MIC

Yes, confirmed that the headphone ports I am using work perfectly on other controllers.

I don’t think anything is missing around the PK contacts.

I tried adding another ground path to PK1, but that didn’t change anything. Is it possible that PK5/7 traces are broken somewhere and they can be recreated?

@Degsy - The TP spots for the Right Stick are in the first post.

Code: [Select]
  O      O
G         x  o
Y
+         x  o
  O      O
   + X G

+ are the AN+ rail. They will measure 1.8v
G are Ground
O are also ground, solder lugs for the stick
o are also ground for the stick button
x are the stick click button
Y is the Y-axis
X is the X-axis


@Greendaycolt - Could be any number of things causing it.

PK5 goes thru R70 (1k) to the 3.3v line.

PK7 has a PullDown R9 (100k) and goes thru R10 (10k) and goes to the MCU board pad 35. I haven't traced it any further than that, but most likely it just goes right to the MCU.

Hi RDC,

Thanks for the help with the headphone trace issue - replacing R70 solved the issue.

I have another issue a different controller: no matter what potentiometer I use for the left stick x axis, it is always drifting in the positive direction, normally by 15-30%. When in center position, wiper to ground measures ~.95V.  Ive tried more than 20 potentiometers that work fine without drift in other controllers, without success on this PCB. Is there any way I can modify the resistance to make it closer to the ideal 0.9V in the centered position?

Thank you again for the help!
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on January 04, 2020, 04:20:54 PM
The issue with that one most likely is that it was calibrated from the factory with a janky POT in there the first place. So no matter what, any 'good' one you put in there will always be a little bit off.

What you need to do is remove the POT from the metal stick housing, desolder the 3 leads then unclip it from the housing. Then cut off the 3 small posts that are in the corners of it, but leave the 2 clips on there. Those 3 small posts keep the POT 'centered' when it's clipped on the housing, and with them removed, and before soldering it in place, the POT will have some play in it to allow you to move it around. Reinstall the POT onto the stick housing and tweak (rotate) it a little bit in the direction that it's drifting. The Wiper position stays the same, but since you're moving the entire POT in relation to it you can change the center value and get it closer to whatever it was calibrated to, and correct the drifting.

Post by: Greendaycolt on January 04, 2020, 05:48:56 PM
It took me 10 attempts but it is finally drift-free. I had to make it a super small tilt, otherwise, it would start drifting the other way.

Thanks a lot for all of the help, you are incredible!

Hi. I have a 1708 controller that was exhibiting this behavior, even with a new analog stick:

(https://s5.gifyu.com/images/1708_stick_problem_22d936f00a4a9edf0.gif)

Checked voltage on TP64 and it was acting up. So I just made a jumper between LSX wiper leg and TP64.
It seems fixed now, but I wanted to know if this is the proper fix or if there's more correct one.

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on January 13, 2020, 01:25:30 PM
If the jumper wire fixed it then there is probably something iffy with the trace or a Via on the board, or the LSX solder joint just wasn't good. As long as it works what you did there is fine and there's no point in digging into it anymore unless you're just dying to know what caused the issue.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"

I think it was the trace itself somewhere, since it tested on the through-hole near the wiper. But doesn't really matter, it's working :)

Houston, we have a problem!  :fear:

Hi guys, the story began when I beat my controller down. I opened correctly the controller to see what was the problem and in the meanwhile I was checking to try some cables, I unplugged wrongly the cable that goes from the (BUTTON/POWER BOARD BOTTOM) to the (MCU BOARD BOTTOM). I think I broke the welding tracks. I'm very good with a soldering iron.
How can I solve the problem now?  :sadno:

That's the RF antenna connector. I'd imagine the rest of it is stuck in the mating connector on the cable now, or if it went flying it's probably gone for good.

The trace still looks intact, just the pad has broken loose from the board for the center connector.

I'd replace the connector, as it will hold the center pad/track back in place then, while the ground connections for it will keep it on the board. You'll need a hot air setup to do that correctly, though could probably pull it off with an iron and a pretty fine tip if no hot air station is available.

The connector is a U.FL (UMCC) Series, Male.

Hello,

I have previously completed this successfully on an older 1708 controller which is now broken after an xbox controller firmware update (it's out of warranty), but I've just tried this on a new 1708 and B is not working on TP41, from either the tactile switch or the B button. I had problems getting the solder to stay put on the PCB and the PCB is a little burned from my 'persistence'. Is it likely I've completely bricked this pad or can it be salvaged by scratching back to the copper contact point? I'm worried I've somehow damaged something beyond repair.

Ground zero;

No one laughing, everyone makes mistakes, it's the only way to learn how to not do something, and anyone that is laughing because they don't make any mistakes, just made one.

TP41 is in the trace there, so if it's damaged then it's possible neither button would work, but it shouldn't be ruined by a long shot.

First thing you need to do is remove the solder, wire and hot glue and clean the board with a Q-tip and some rubbing alcohol so we can see what we have to work with. I'd suspect the trace is damaged right under the TP41 spot, as that would disconnect either button from the B button line, so neither would work. If that's the case, then you can prep and solder to the Via just below the TP41 spot, then jumper wire it to the bottom of R29 and the controller's B button should work again.

Tip for you: Tin your wire ends before soldering them to any trace/pad spots. That is strip the end back some, twist the strands together and then solder it up so there is solder on the wire already. The insulation on that kind of wire will melt a little and shrink back, then you can trim the tinned end to a shorter length and it will take you far less time to get it soldered to the spot in question, versus having to heat the wire, trace/pad and solder all up at the same time to get things to 'stick' together.

Post by: uwonbidvd on March 22, 2020, 02:44:25 PM
Wow RDC, thank you for that brilliant reply. Really useful, I will get onto that. Good to know I might get another shot :)

I attempted to tin the wire but it didn't have enough solder on it, in hindsight. If I tin it correctly, do I even need to apply more solder to the join? That was a struggle and I did have those helping hand things. The only soldering I've ever done is to fix small electronics, and mostly it's been xbox related like a thumb stick module. I should probably get some more practice in on some spare parts I have laying around too...

Thanks again, I'll report back
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on March 22, 2020, 02:57:33 PM
Welcome.

Depends on how much solder is left on the wire from the tinning, so kind of depends there. If you tin the wire, then tin the joint, most times you wont need any more solder after that.

Yeah TP41 is a goner. Just prep and solder to the Via right under it. An X-acto blade or fiberglass pen if you have one is all you really need to remove the green mask and expose the copper. When you start to see copper slow down because the shiny copper isn't far under that and that's what you want. You don't want to go any farther than the shiny copper or you'll end up on the bare PCB then. Even if you tank the Via there, you can go to the other side of the board and try there, or even right to the castellated connection pad 15 of the MCU board, where the smaller MCU board is soldered to the main board, it's in the corner there kind of under the antenna.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: uwonbidvd on March 22, 2020, 03:53:41 PM
Yeah, it looked pretty nuked. Do I still need to do;

"then you can prep and solder to the Via just below the TP41 spot, then jumper wire it to the bottom of R29 and the controller's B button should work again."  ?

Or can I just scratch the green bit in the Via down to the copper and attach my grey wire for the B switch to that (option A) ala "Just prep and solder to the Via right under it"? I Googled 'Via' quickly and it says it connects to other layers of the PCB or the other side, so in this case does it bypass using TP41 for connectivity or is jumping a wire from that to R29 the 'bypass', so to speak (option B)?


The grey wire is my B wire to the tac switch.... hopefully it's clear there is a A or B option;

Yes the Via is the little 'donut' there that connects traces from one side to the other, it's like little copper tube in the board with a copper washer on each end, would kind of look like an empty spool if you could see it all on it's own.

The B option will restore the controller's B button so it will work again. Option A would be for your duplicate B Tact button and then only it would work. You could also do both if you wanted.

Just to confirm, this would need me to jump a new wire from the same solder spot I've just used on the via below TP41, to either of the above locations? So the top of R29, not the bottom bit?

No more jumper wire. Go from the top of R29 to your new Tact B button, or use pad 15 on the MCU board and go to the new Tact B button. You can use either of those in place of the original TP41 to make your duplicate B button.

Take a multimeter and measure the Resistance from TP14 to Ground, then compare that measurement to TP15, 16 or 17 to Ground.

If TP14 measures 0hms, then there could be a short on the DR line from the button to U4 somewhere, or U4 could be bad.

If TP14 and any of the others measure the same, I'd suspect that U4 is bad.

Best place to get another one is from another broken or donor board, but it's just a Schottky on the 5v rail to the Vin of U1, so just about any diode there would work.

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on April 19, 2020, 02:47:23 PM
The spot for LT is right next to where you soldered for the LSY, so possibly bridged something there? That wouldn't have any effect on RT though.

Are they dead? Kind of need a scope to see what it and isn't working there because those things are pulsed 125 times per second and a digital meter can only get you so far there.

Are they acting like they are pulled all the time? If you removed the magnets they can be put in backwards and will act pressed all the time because the pole is reversed.

Can anyone enlighten me as to how the circuit works that powers the controller from batteries?? I've got a controller (like many of the others on here) that only works from USB but will turn on as long as I hold down the guide. Once I let it go it loses power. Guide button works fine when plugged in but it just won't turn on the thing. I have checked the components to the best of my abilities and can't find anything noticeably wrong. I'm thinking there's a busted trace somewhere in there but am having a really hard time following the signal once it gets past R27. With all the diodes and the MOSFETs in there I can't keep track of where I should have continuity or not!
Everything looks good from the POK side on the J1 connector but I have a feeling theres a broken connection somewhere in that circuit that prevents the guide from powering on the controller.
I've scoured this forum for similar issues and found a few that are exactly the same but I've checked everything on those posts and still can't find the issue   :cry2:

Check and make sure L1 is on the board first.

The POK signal comes from pin 9 on J1. Make sure R7 is good, it's 0ohms, just a jumper but if it's missing or damaged it'll never get the POK signal to stay on. You should have continuity from pin 9 to D26, then make sure D26 is good.

Hello good evening, how are you ... I hope everyone is super cool .. See if you can help me. Someone gave me a control with a problem with the right stick ... I opened it and I see that it is already repaired. And several dead tracks. Could you help me how to fix it, to make a bridge or something. After opening it and seeing that I understood why they gave it to me :dntknw:

First, clean all of that mess up and retouch all of those solder joints for the stick there, in fact just remove what solder there is at the spots marked in Red.

Remove the black and red wires, they aren't doing anything anyway.

Connect the Red marked spots together with a short jumper wire, then go from either one of those with another wire to TP103, farther over to the right side of board.

Connect the Blue marked spot to TP65, middle of board.

Connect the Green marked spot to TP71, can be seen in your pic.

Test controller and see what works or doesn't.

Hi

Awesome post, i've learned a lot!! I have two separate controllers with two issues.


Controller 1: RT always reads a 70% pull. Hall effect sensor should be ok as i didn't go anywhere near it. TP67 is toast and there's no more solder on it (I accidentally removed it...). Is there a way to jumper around it?

Controller 2: Right dpad button is not working at all. Looking at the controller, TP14 is a goner as well. Likewise, any way to jumper around it?


Thanks! This thread is awesome.

1 - You'll have to prep and solder to the via just below TP67, then go from there to the bottom side of C36 or R39.

2 - Prep and solder to the Via just to the left of TP14, then go from there to the top side of D10.

Post by: xkse on April 26, 2020, 07:06:20 AM
Thanks!! Was able to jumper the TP67 via to the bottom of C36.

The other controller....i soldered a jumper wire to the via next to TP14 and tried to solder the other end to the top half of D10. Something went wrong:


the right d pad constantly thinks it is pressed, and when i press the LEFT d pad, it turns off. And LB thinks it is pressed. Something is shorted. I removed the wire from the top of D10, but this is still happening:

Right Dpad and LB constantly on. When I press Left Dpad, the right dpad turns off (while i hold it).

LB isn't near DR, so the odds of those issues being related without some intervention is pretty up there. Post a couple pics of your board and where you soldered on it.

I also have one of those lofty PCBs on there, so i'm guessing the ribbon cable is shorted somewhere. I'll start there.

Post by: xkse on April 26, 2020, 11:14:37 AM
Yeah the LB issue isn't happening, at least in the moment.

But, DR acts as if it is held all the time, and holding DL turns off DR (but doesn't turn on DL).

Looks like it's shorted. Also, unless that wire has an enamel coating, like magnet wire, make sure it doesn't touch anything else in there on it's run to D10.

Yeah it's just a strand of copper speaker wire. I hot glued it in some spots away from the solder joint so hoping it doesn't touch anything on the way in the future.

Check and make sure L1 is on the board first.

The POK signal comes from pin 9 on J1. Make sure R7 is good, it's 0ohms, just a jumper but if it's missing or damaged it'll never get the POK signal to stay on. You should have continuity from pin 9 to D26, then make sure D26 is good.

Eureka! I think that's it! I checked so many things and they all checked out but I do NOT have continuity between Pin 9 and D26. So now my question is, how the heck does Pin 9 get to D26? As far as I can tell Pin 9 just has one trace that goes over to R4/C37 which ends up at U4. C37 also goes to EG2 and R7 which has a via that leads to ... R8\TP26? which isn't on the board on any of my controllers so I'm guessing it's not used. It also heads over to what looks like underneath Q9 but I can't get continuity on any of my controllers there so I'm not sure. I'm just trying to pin point the break so I know what to jumper to.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on April 28, 2020, 06:49:23 PM
Pin 9 hits R4, R7 and EG2. R4 and R7 are both 0ohms. After R4 it hits C37 and pin 24 of U4. After R7 it goes thru a via to R8 (not installed) and to the Anode side of D26. There is a via under Q9 that connects the top trace from R7 to D26. First check for continuity from the top pad at R8 (not the one that is connected to TP26) to the left side of D26. If it still measures no continuity there, then just run a jumper wire from that top R8 pad to the left side of D26.

After checking I found that there was a break in the trace from R7 to the via next to it. Just soldered a little jumper wire there and it works!!

Excellent generous help by RDC on this thread, so here is one that should be easy to answer...I hope.

1708 board.
fault - NO LB response

put a new switch in - no change.

Not a multi meter or electronics guy, but can check continuity....
from LB down to TP 19...seems to open close fine.

however....i check across LB solder points on a working power board I get a reading of..700 or so
across the same points on faulty board....0

so a dead cap somewhere ? or a break somewhere ?

any advice for a newb to check ?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on May 07, 2020, 09:08:18 AM
Here's a bit of a tip for everyone. Don't use the continuity setting on the meter to check for continuity. I know that probably sounds wrong, but those things will all squeal if there is some Resistance there. So it may actually be 100ohms or so, but the meter will squeal and then you assume it's connected straight thru, when it's actually not. I know it's nicer to do that, so you're not having to focus on the meter, and if you want to use it to start that's fine, but then go back and use the Ohms setting and make sure it measures close to 0 ohms so you know there's nothing funky going on there.

If you're measuring 0 ohms across the LB button (same as measuring 0 ohms from TP19 to ground) then it should act like it was pressed all the time instead of being dead. How does it act in any controller testing app? Windows, HTML5, anything that lets you 'see' which buttons are pressed.

If you can measure 0 ohms from the LB to pin 6 of U4, then the LB trace should be good. Pin 6 is on the left side, bottom corner if you're looking at the board how it is in the pics in the thread here. Then measure from pin 6 to ground and press LB and see if the value changes from something really high when not pressed (over 1M ohm or open) to around 0 when pressed. If all of that checks out as described, then U4 is most likely bad.

Post by: theADDict on May 08, 2020, 02:40:40 AM
Ok mate, firstly thankyou so much for the advice and tips.

So, if this makes sense, now using top ohms setting.


Across lb.... No response
Tp19 to ground.... No response

Controller testing app..... Everything fine bar no response from pressing lb.

Pin 6 u4 to lb  - no response !!
Pin 6 to ground - no response
Pin 6 to ground when button pressed - no response again !!
of course, pin 6 to LB, with lb pressed....nowt
LB  to tp19 - open/closes fine

So.....question one - is the via right next to pin 6 a connection for pin 6 ? if i clean I could check pin 6 is connected to board i thought.
q2 - can I link pin 6 to lb...easiest way ? or is u4 a gonner ?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on May 08, 2020, 11:32:19 AM
LB to TP19 can not open/close fine, as those two spots should be connected.

LB to ground should measure open then short when the button is pressed.
TP19 to ground should do the same.
Pin 6 to ground should also do the same.

On a working controller that is. If you have the first 2 of those measuring correctly, but the third one is where it's failing, then the issue is either at the via for TP19 on the top side of the board, the trace from that via to the via right under where it's marked EG2, or the via/trace at bottom/left corner of U4.

You'll need to peel up the top of the D-pad about 1/4 of the way to follow the LB trace. It's easiest to follow from the via under EG2, and it's the trace closest to the top of the octagon opening there. You can measure from that via at EG2 to the top of D1 to check the trace.

The castellated pad 62 on the small MCU board, where it's soldered to the larger board, is RT. Then LT (TP68) is pad 52 for comparison, RT is 10 to the left of that pad. The top row there is 80 to 43, going left to right.

The Antenna is on the Button/Power board. That is a coax cable, a thin wire inside of a shielding wire, that's how the Antenna connection gets to the MCU.

thanks to your patient guidance and perfect info....we have a working controller !!

scratched off the via by EG2, tested from there to LB - same result.
Got the old magnifying glass out, follow along...along..along, and boom, tiny section broken trace.
Ran a 'lil wire from LB to the via....tested.....controller like new.

Hello, big noob in electronics here. I recently got a controller from a friend and he told me that I can take it and fix it for myself. And this has a very strange fault. The IC labeled U1 completely burned and with it also the resistors, capacitors and diode around it. I know that the only possible fix is to replace the entire board especially because the PCB is destroyed, but can anyone tell me why this happened and how? I was assuming too much current passed in the component. I don't want to get this fixed and repeat the same error.

Could be they just plugged it into some higher output USB source. Without knowing how the thing was treated it's entire life you'll never really know why it happened. Electronics can just up an do that sometimes also, as there are hundreds or thousands of transistors in those tiny packages and when just one goes it can avalanche into a mess like that.

Morning all.
Time to nag RDC once again.

Dived into my box of spares, and this 1708 top board came to hand.

Problem.... No dpad response at all.

Diagnosis didn't take too long..... Cracked board in thin area under right stick cut out,  right where LB1 is printed.

Can see 4 via to the right..... Where are the best... Or rather... Easier. . points to solder to ? Are there easier points on other side of board ??

Edit : on further examination.... Think this is one for the spares bin.

You'll be soldering to some vias to jumper those traces back together, also the Sync button trace runs thru there as well, so it's probably dead too.

To restore..

DR - TP14 to the top side of D10. (both bottom side of PCB)

DL - TP15 to the via for pin 13 of U4 (both bottom side of PCB)

DU - TP16 to the via for pin 11 of U4 (both bottom side of PCB)

DD - TP17 (bottom of PCB) to the bottom side of D12 (top of PCB, bottom left of D-pad)

SY - TP18 (bottom of PCB) to the left side of C27 (top of PCB at SY button)

Hello! I was doing the extreme rate remap kit and ended up pulling off a few TP's. I was able to fix most of them, but I do not know where to wire TP11 to. Also, despite the fact that TP66 was not touched at all, my right sticks X-axis does not work. Upon checking the continuity between TP66 and the black hole connected to where TP11 used to be, I get a short beep. When I did it with a working controller, I got no beep at all. What should I do? Thank you.

Not sure why they are using TP11, a couple other places for that particular spot are pin 3 of J5 or pad 70 of the small MCU board. If it's supposed to be the power for the thing, then using TP9 would be a better choice as it's a regulated 3.3v source.

Take the meter off continuity and use the Ohms setting to check traces.

Post by: aydinrad on May 23, 2020, 01:45:40 PM
I'm not too concerned about using the remap kit anymore, I just want to fix my right stick Y axis(I might have accidentally said X axis on the last post). I used the ohm setting to check the traces for TP65 (the RSY) and both traces give me around .3 ohms (I got the same numbers on a working controller so I assume the traces are fine). Upon checking the right joystick, I noticed the Y axis pin had a similarly low resistance to the ground pin on the joystick, whereas my working controller had a high resistance. Another observation I made is that the resistance between TP 65 and the black hole connected to TP11 is 200k ohms on the working controller and 3M ohms on the broken controller. Is this because I accidentally pulled off TP11 on the broken controller, or is it something else, like my right stick (which worked perfectly prior to ripping off TP11)?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on May 23, 2020, 01:56:17 PM
TP11 doesn't have any trace running thru it, so it it's missing then it's fine like that.

Measure from TP65 to the center lead of the RSY POT, that should be right around 0 ohms. If it is anything higher, then connect those together with a jumper wire.

A tip for you, don't go jamming test leads into the vias, as that will give you a bogus measurement unless you stab it in there and pierce the solder mask and at that point you can damage them and cause an open in the trace and more issues.

I'm not too sure what you mean. Is the POT the physical joystick with the 14 solder points? If that's the case, which one is the center one? Also thanks for the advice, I am new to all of this.

The POT is the Potentiometer that clips onto the side of the stick. The 3 leads in a row are the POT leads, one is for X-axis (left/right) other is for Y-axis (up/down).
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: aydinrad on May 23, 2020, 02:50:41 PM
It is .3 ohms. So no jumper wire?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on May 23, 2020, 02:54:56 PM
Correct. That 0.3 ohms is the resistance of the trace and mostly your test leads, so that means it's connector from the POT to the TP65.

Is the thing acting like it's pressed all the way up or down on it's own? or what is it doing exactly?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"

The stick is completely centered. it moves left and right perfectly, but it does not register vertical movement at all.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on May 23, 2020, 03:05:21 PM
You'll need it powered on for this test, so be careful poking the leads around in there while it's running. Nothing in there will give you a jolt, but shorting out the wrong things while it's on could kill it.

See what the voltage is on the center lead of that POT. Red test lead on the center POT lead, black test lead on any ground spot, meter set to DC volts. It should measure right around 0.9v, and that value should change up and down when the stick is moved up/down. Lower voltage when moved up, higher voltage when moved down. If you measure the 2 outside leads of the POT, it should be 1.8v, or -1.8v depending on which way you have the test leads, but either way it should measure 1.8v

Post a pic of the board there where you're measuring, just that general area. Something is really not right, because if that Y axis line is measuring 0v then it should be acting like it is being pressed up all the way.

Well for a functional stick that's impossible as there was 0.9v on the X-axis POT, so it was getting voltage. That jumper wire should have put the voltage to the Y-axis POT. Has that stick been replaced? It looks like very single solder joint on the thing has been had at.

It has been replaced, but it worked after the repair. It stopped working when I tried to install that button remap kit and tore out the solder joint for TP11, TP67, TP41 on the MCU board and TP20 on the button board (yeah I really goofed). I was able to restore functionality to all of the buttons affected by my mistakes.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on May 23, 2020, 09:25:56 PM
The only way for there to still be 0v on the center Y-axis POT lead now is if the POT has an issue. Unless the jumper wire you put on has a break in the middle of it, which I'd doubt. Measure voltage on both ends of it though, with respect to ground, they should both measure 1.8v. If the center lead of Y still measures 0v and you do have the 1.8v on the bottom lead, then that POT is the problem.

Only thing that makes sense so far. You can try resoldering the middle lead and remeasure it, see if anything happens. Kind of odd for one to jut up and die that was working, but I've seen weirder things.

Do you think it could be the little sensor inside the POT that isn't working? I've had success fixing stick drift by replacing those.

The only thing in there is the Wiper. It's either that, the resistor trace inside the POT or the lead is broken.

Post by: RDC on May 23, 2020, 09:56:07 PM
Yep. It doesn't sense anything, it's just metal, and it doesn't rotate all the way around. It 'wipes' over the resistive trace inside the POT to change the value you get on the middle lead.


The Sticks are just voltage dividers. One side is connected to ground, other side is connected to 1.8v and the middle is connected to the Wiper and is what the controller measures to tell what position it is at. The more you move it one way or the other the higher/lower the voltage you'll get out of it, between 0 and 1.8v, with 0.9v being the center value, since 1.8v / 2 = 0.9v

Hello there!

Today I received a smelly controller, and by opening it this was shown:


(https://i.postimg.cc/yJqnx7R5/placa-1.png) (https://postimg.cc/yJqnx7R5)


(https://i.postimg.cc/mtv7N8r1/placa-2.png) (https://postimg.cc/mtv7N8r1)


The burn was so nasty, a cap now lives fused to the plastic shell:


(https://i.postimg.cc/V5zGXshP/plast-quemado.png) (https://postimg.cc/V5zGXshP)


Except from this little detail, the controller was in mint condition.

Here where I live it is difficult to get a new board fast and cheap. So it was time for some ol' 3rd world engineering...

Upon removing all the bloated components (IC, mofets, ++), I managed to provide power to the other regulators by passing 5V to the V+T trace. TP35 checked 3V3, and the controller seems to work nice from USB power now (at least for the few hours I've tested it).

Now if I could make the controller run like this on batteries, I would forgot to order a new board. I tried connecting L1 to the V+T trace, and TP35 checked 3V3, but the controller wouldn't start. Does the blown circuitry provide 5V from the AA to some key section I'm missing? Or maybe some kind of check? I'm curious now...

Thanks again RDC for your board pics & schematics! This is the second time I use them, and they are great. Greetings from South America!

Welcome.

The V+T rail is really the 3v/B+ rail. When powered from USB it's 3v, then battery pack voltage when run from them, I need to update that schematic a bit. That's all that U1 does, it just knocks the USB 5v down to 3v for U2 and U3 to step up to 3.5v and 3.3v respectively. Those chips have a max input of 6v, better for them to be run from 0.6v to 4v though.

I've only ever removed U1 alone as a test, but know the controller will work from a battery pack if just that chip alone is missing.

That whole Q6/Q7 area is responsible for getting the battery pack voltage onto the 3v/B+ (V+T) rail, so some of that will need to go back in there to get it to work correctly from a battery pack. Then Q8/Q9 is responsible for turning that Q6/Q7 mess on/off so the battery power isn't always connected to the 3v/BAT+ rail, because if it is then U2/U3 are always on.

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: Ramon2221 on May 29, 2020, 05:26:58 PM
Thanks for the data RDC.

I finally could power up the controller from batteries. I discovered that I must press the power button within 2 seconds of placing the AAs, otherwise it wouldn't start. And yes, as you said, it has a current of about 60 mA while powered off with the Bat+ connected to the V+T rail.

Good to know about the voltage limits in U2/U3. Now I drop about 1.5V with two diodes in series from the 5V line.

I think I'm happy with the result (the joystick belongs to a friend, if he wants full capabilities he'd have to get a new board).

I've replaced the bad joystick with a known working one and the right stick Y axis is still stuck all the way up. I also put the bad joystick on another controller and it works completely fine. Any advice? It seems the POT is not the issue.

Post by: aydinrad on May 31, 2020, 03:03:47 PM
The center lead for the Y-axis is at 0V, the one below it is 1.8V (as it should). The X-axis leads are getting the expected voltages.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on May 31, 2020, 03:13:15 PM
That's just straight up not right unless the center lead is shorted to ground somewhere. Measure the Resistance on the POT leads to ground.

The Top lead of the POT to ground, should get 0 ohms

The Center lead to ground, should get around 4.4k

Bottom lead to ground should measure around 2.5k

If you get 0 on the center lead, there's a short on that line to ground somewhere.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on May 31, 2020, 03:23:43 PM
There is either a solder bridge at the top and center solder joints, C23 is shorted, somewhere along that trace is shorted to ground, or something on the MCU board has died.

Post by: RDC on May 31, 2020, 03:32:16 PM
If you removed it from the board and checked it, then yes. However, if you tested it on the board then all you're doing is the same thing as checking the center lead to ground and reading the same short.

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: aydinrad on May 31, 2020, 04:06:36 PM
A potential source of short could be the soldering I had to do to reconnect a few test points related to the controller buttons. Here's a photo https://photos.app.goo.gl/y9KUu4KivrVg1wb86. The resistance from the center lead to the wires is in the thousands, leading me to believe it is not the culprit though.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on May 31, 2020, 04:38:08 PM
Looks like there is solder splash on C23 in that pic. Solder splash is just excess solder that lands some place it shouldn't and usually causes shorts.  Since you were soldering there just above it at TP67 that could be where it came from.

You can remove C23 with and iron, just drown it in solder so both ends get heated at the same time, but if it just has some splash on there then just knock it off or if it's really stuck on there heat one end then the other so it will open back up.

If you mean RSC (called R3 on the Sony controllers) then there has to be a short on the RSC button line somewhere or the MCU has a weird issue. Have you replaced the stick or done anything to this controller? I've seen the button in the stick get corrosion in it and that Resistance is enough to register a button press.

I used this thread to replace the left joystick on the slim 1708. It was my first time so I lifted some pads and had to use jumper wires front he joystick pin to the board. All was good for about a week but then the Y motion stopped working. I thought maybe my jumper, which had a cut in the insulation so I replaced it. Now the Y doesn't work and the X is glitched moving back and forth quickly.

I saw an older post that had something similar and they had an issue with TP64. I see I messed up TP64 could that be the issue?

The reason LSX is glitch now is because TP64 is missing. The trace runs thru it, so it's basically open now and 'floating' so it done' know which way to go. Solder a jumper wire from the center lead of the LSX POT to the solder joint that is just below where TP64 used to be. Directly between the 64 in TP64, go straight down from there.

For LSY, clean up those bottom 2 solder joints of the POT first. Then solder a wire from the center lead of that POT to the solder joint just to the right of the one you just did for for LSX above. IF the bottom lead can't be reconnected to the via, you can solder it to the left one of the LSX POT or to TP103.

Hello RDC, I have a controller (1708 as this thread) which has the “menu” button constantly on, I already tried with a new contact/ rubber pad without luck. Therefore should be a short on the capacitor, I tried following the trace and I’d like to confirm with you if is either the C1 or L1. Or if is not a capacitor short where to jump the button?

Check the Resistance from TP25 to ground with the View button unpressed, then with it pressed. If the value does not change then the trace is broken between TP25 and the View button, or you're not pressing the View button.

If the value does change from some high value (unpressed) to around 200 ohms or less (pressed) then the trace from View to TP25 is good. Check the Resistance from U4 pin 15 to Ground and press View again. If it does not change value the trace is broken between TP25 and pin 15. If it does change value then suspect U4 is the issue.

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on July 20, 2020, 08:17:30 PM
If it's always pressed then make sure the membrane isn't worn out and the thing still 'snaps' on and off. Ohm out TP16 to ground and see what it measures pressed and unpressed, controller off and top board disconnected from bottom board.

If TP16 to ground always measures 0ohms then look for a short to ground on the DU line.

If there is no short and TP16 to ground measures normal (high resistance unpressed, low resistance pressed) then I'd suspect that U4 is the issue.

Pin 2 of J1 is the Guide button, not sure what you're trying to look for there.

U2 and U3 get their power from U1 when connected to USB, or the battery when used wireless. Check R1 and then U1 and it's support components. That U1 regulator takes the 5v from the USB and knocks it down to 3v for U2 and U3 to use, so there's an issue whit it or whit the 5v getting to U1.

The castellated pad 62 on the small MCU board, where it's soldered to the larger board, is RT. Then LT (TP68) is pad 52 for comparison, RT is 10 to the left of that pad. The top row there is 80 to 43, going left to right.

Hello RDC I have this same issue, but in my case C33 was shorted and by removing it out took the bottom pad with it and now is all the way to 100%, tried jumping c36 and r39 to tp67 and from there to pad 62 and still the same.  Any idea?

The RT line was fine if all you damaged was the bottom pad of C33.  Removing the bottom pad of C33 took out the VCC to U10 there. Jumper pin 1 of U10 (marked with the dot) to TP50.

That looks like it's some kind of Arcade Stick mod, being they removed the Hall sensors for the Triggers and the Sticks from the board and have Resistors installed, so the 'LT on stick' would be the LT button of the Arcade Stick.

RT MOTOR+ is TP29. It's actually TP29 on the 1537 as well, has those backwards for years now, so that's also been corrected.

Got it, thanks a lot.

The board I am dealing with has a crack in the area of the right stick. I've managed to route most severed functions to test points to get them working, but the RT MOTOR + spot and TP29 are not providing power for the function. Is there any other spot where I can intercept this signal? Maybe somewhere to the right of the right stick, if I am looking at the bottom of the board.

U5 on the top of the MCU board controls the Light and RT Rumble motors.

Here's where the crack is - I wired RSY and RSC to their respective test points successfully. Perhaps I need to wire the RT MOTOR + directly to one of the pins of U5?

The connections from U5 to the motors is short and nowhere near that crack.

One or more of the 4 control lines that go to U5 are probably broken somewhere. Those traces are on the top and bottom of the board and all run right thru about the middle of the Stick there. I'd remove the Stick first, because if the traces on the bottom are cracked there very well could be damage on the top side as well.

This is all the further I'm currently tracing them out. I'd have to pull the SOC board there or poke around with the DMM to see where they end up on the SOC board points, but odds are you have a break on one or more of those 4 there somewhere.

Yes thanks a lot, very appreciated. This info is great! Your schematics helped fix an issue with the 7 buttons pressed fault https://acidmods.com/forum/index.php/topic,44652.0.html (https://acidmods.com/forum/index.php/topic,44652.0.html)

I checked everything mentioned in the thread and even replaced the U4 chip twice and nothing worked out. With the schematics there was VCCI, VCCP and ADDR connected to 3.3V and turned out there was a break in a via on my board for VCCI and VCCP, but ADDR had 3.3V. So it was fixed with a jumper, many thanks!

CR1 is a Diode. It's nothing special, just some Schottky diode for the 5v reverse polarity protection. You could leave it off, or install just about any type of Diode you want there. Cathode goes to the 5v rail (the right side in that pic) Anode goes to Ground.

I have another problem controller - this one needs RSX connection to be recreated but TP66 was ripped off the board. I can see where the trace leads to TP66 but cannot see where it goes after TP66 (which is where I think I need to jump the connection to). Any advice is appreciated as always!

Thanks RDC. Maybe I misunderstood the spot because per the wiring in the picture, the RSX value went from a erratic ~-60% to a constant -100%?

I also jumped Vcc and ground from one of the working potentiometers to the inputs of RSX just to make sure nothing funky was happening there.

Post by: RDC on November 21, 2020, 05:18:37 PM
That's the right spot, but make sure that it is only touching #19. I can't make it out from the pic for sure, but it looks like that RSX trace is possibly grounded out on the one next to it, which is ground, and grounding the RSX line would make it go -100% there.

Hi guys, I need your help.

This is the second time I try to repair an XB1 controller's bumper.
While the first time it went smoothly (beginner's luck I guess), this time I'm afraid I've been able to lift all the 4 pads, while desoldering the LB switch.

(https://i.postimg.cc/Lg8YpZGB/IMG-20201122-140654.jpg) (https://postimg.cc/Lg8YpZGB)

I dunno what to do, can you tell me if it's fixable or not (the other buttons work anyway)?
Sorry for my poor work, I have practically zero experience in soldering

Got it, thanks a lot!

It was only touching #19, the issue was that the normal RSX pad was somehow being grounded somewhere along the broken trace, so I simply made sure the RSX pin on the potentiometer was wired to #19 without any contact to the normal RSX pad.

Thank you again RDC - you have helped me and others countless times and are always generous with your knowledge.

@ Greedaycolt - Welcome.


@ Rocky98 - It's for sure repairable. Three of those 4 connections are ground anyway. Easy enough to just scrape a little bit of the solder mask away, the green 'paint' that is covering the copper underneath it. Then bend over those 3 leads and solder them to the board there.

The fourth connection is the LB button line, and you can run a wire form that one to TP19.

Thanks for helping me
So, I need to scrape anywhere near those 3 pins, the copper will emerge and then I'll bend those pins and solder to the copper, am I right?
Or I need to scrape somewhere specifically?

Dark green is the solder mask, copper is under there. Scrape gently, don't dig for it. When you see the shiny, you're there. nowhere really specific, but has to be where the leads will bend over and touch.

Sorry to be a pain, got a 1708 that wasnt turning on via USB, the port looked damaged so I replaced it. Did the trick for 5 minutes but the pad randomly loses power.

I suspect U1 is not working correctly as I know this knocks down the voltage from 5 to 3.3. which pins are Vin and Vout so I can test it?

I have an ECU board per picture below that has a constantly activated RB (RSC) input. I ensured ground is present at 3 of the four pins and jumped wires to the grounds from the working LSC just to be sure. I then jumped wire from RSC to TP20, but RB is still constantly activated. No visible damage on the board. Any ideas how to further troubleshoot/fix?

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on November 30, 2020, 01:49:51 PM
RB and RSC are 2 different buttons.

RB = Right Bumper
RSC = Right Stick Click (the Stick button)

Given the pic, you're having an RB issue.

First check the Resistance of the RB button line to ground.

If RB measures a few k or less, look for that issue on the trace between RB and U4. Could be the Tact has failed or has some crud in it as it doesn't have to go directly to ground to register as a press. Could be the trace that runs under the AA post there since it's the negative one.

If RB measures a Meg or more, then U4 is most likely bad. I've seen that thing fail and kill just a single button or two while everything else still works.

Post by: Greendaycolt on November 30, 2020, 07:40:55 PM
Thanks RDC. You are awesome - this board is working now!  :#1:

Resistance was about .24M Ohm, so I cut the trace going from TP20 to RB, very close to where TP20 is on the flip side of the board, and jumped TP20 to RB.

Hey RDC, sorry to bump this one up, but need a little help.

You helped me a long time ago (about 15 yrs) get my original wireless arcade controller done for 360.

Well, I am updating it to a 1708 S controller pcb. I have everything soldered to the xbox controller boards and then to the arcade buttons and joystick.

So, heres the problem (and I know it's an easy one). Everything powers on and tests great with the micro usb plugged in. All buttons work and all is g.

But when I try to connect external 2xAA pack to the battery contacts on the button/power board I get nada. I noticed there is a little tab that hits EG1 on the button/power board and guessing that has something to do with it.  ???

Any help is appreciated and sorry for dumb question.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on December 31, 2020, 03:48:19 AM
The EG1 isn't causing the issue, that's just another ground, and it does that thru 2 pins on the connector there.

Was the controller confirmed working on the AA before it was torn apart?

If so, first make sure you're getting the + and - connected correctly (have to say it, because if I don't then that's what it would be) then I'd check and make sure is that L1 is still on the top Button/Power board and that it did not get cracked in any of the corners of the octagon opening there.

Post by: beardawg252002 on December 31, 2020, 04:09:46 AM
Yes, controller was confirmed working with 2xAA before tear down. I tested it thoroughly before working on it.

And, no worries, I will get a close up pic of my wiring tomorrow to the battery contacts. Pretty sure it's right and checked it first thing when it wouldn't power up with AAs but would power on with micro.

I will check L1 and let you know on that too.

Thank you for all the help and info on this site.

Also, any alternative wireless powering ideas if the battery contacts won't work. Like a 5v to the micro connector or something. I know that connection works at least.

Any further help on a location for L1 on the button/power board? I am not finding it and have to go off ur scans since xbox PCBs are mounted for now and hoping to solve this without removal. Around the octagonal opening for the analog stick correct?

Something about that L1 don't look right. Maybe it shifted when it soldered and it's fine, but it's not on there straight. Take a meter and put the AA in there and check the voltage from any ground spot to each side of that L1, should have ~3v on each side of it.

I may just run with the micro usb and get a usb battery bank, run micro usb cable into there. Works great on micro usb and would have crazy battery life.

Thoughts?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on December 31, 2020, 05:31:36 AM
It might work that way, but 5v on the USB lets the controller know the cable is connected, so it may try defaulting to a wired state, never tried that before to see how that acts. I'd still wonder what was up with the AA path. The 5v input has to go thru U1 first and gets knocked down to 3v for U2 and U3 to use, whereas the AA goes to U2/U3, via Q6/Q7. Since it works from the USB everything is good as far as U2/U3 are concerned, so the issue has to be L1 or around the Q6 and Q7 area not letting the AA 3v thru to U2/U3.

I pulled it all apart and checked L1 and Q6/Q7 under 10x mag. It all looks fine. No cracks, solder looks good.

Hmmm, was going to redo some stuff but now not sure where the problem is. Going to try hooking it up to AA now with it all out and see if it changes.

The usb packs work good, but eventually disconnects on me. The 5v 1A works best and almost never disconnects. The 5v 2.5A disconnects often.

Going to see what I can see and possibly try again with fresh boards, but want to know what happened first.

Also, I forgot to mention it said a headset was connected to the controller and there was no headset connected to anything.

Maybe a grounding fault.

I wonder if that EG1 contact needs to be in the loop still.

There is a contact in between the batteries in the stock controller battery holder that touches that point on the button/power board. Why?

Most mods don't require total removal of the boards from the controller. They usually go back into the original case but modified. So, it's kinda the only difference I can see. Outside of me toasting something or breaking something.

The fact that all buttons, sync, guide and all that work fine makes it hard to believe I screwed up that bad to make it not accept battery power. I checked and rechecked all solders and components on both boards and don't see anything obvious or damaged. I could have screwed something up for sure, but everything around my solders is good.

I don't have my fluke right now to test the voltage on L1, but that may be next. Gotta get it back from my buddy.

Sorry for the long posts, but was so close and want to know what happened.

I solder to vias right by the test points. I don't see it causing any issues on this board except for maybe TP17 with that resistor in play. But, when that button worked just fine (DD), I thought I was good. All the other solders are uninterrupted from TP to closest via.

Lmk if any further thoughts come to you.

Post by: beardawg252002 on December 31, 2020, 03:20:46 PM
Also, no headset jack in there cause it's just floating between boards.

Could that be causing the issue somehow.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on December 31, 2020, 04:57:30 PM
EG1 isn't causing it.

Headset connector missing is not causing the AA issue either, but is the reason it shows the Headset is plugged in. If you plan to never use a wired Headset with it then on the MCU board jumper the PK2 contact to the PK3 contact.

If you've scraped and soldered to vias then something could have been damaged during that process. The wiring is stripped back quite a bit as well and could be shorting on something else in there.

Does the Guide button work when connected with the USB?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: beardawg252002 on December 31, 2020, 05:43:07 PM
Yep, guide works. Everything works except AA power.

Got it on the headset. Ty.

Well, guess this one we won't know. I am pretty careful and exact in my solders, but possible I hosed it up.

Via prep and soldering is easy. And I double checked them all under 5x mag, so I think I would see damage or shorts. All traces are in tact around my solders, I checked under 10x mag.

??  Try again I guess.

You'll need to poke around in there with a meter and see where the AA power is not getting to. L1 is still top of my list, with some solder bridge or other issue around that Q6, Q7, Q8, Q9 area causing it and being where I'd look next.

It won't power on with the battery pack, but it will stay on if I start it up with usb plugged in. Then I unplug the usb once fired up and runs fine. Been on AA batteries for 10 mins now. So.... stable but why no start up? All buttons work under AA power also.

Least you know L1 is good now.

Follow the schematic and look around everything connected to Q8 and Q9 there. You either have something shorted in there still, or possibly damaged something in that area.

Pressing Guide turns on Q8, which turns on Q9, which turns on Q7 and that sends the AA+ to U2/U3 powering the controller up, which sends power to Q9 via J1p9 and D26 which keeps Q9 on after Guide is released. Issue has to be in there somewhere with Q8/Q9 or the Resistors around them.

Thank you so much for your help and time. At worst I redo it and do better.

I will look there again with the scope and if not, I have a backup controller. Pretty sure I can nail it second try if all else fails.

It's gotta be R24. It looks ok but must have failed somehow when I over soldered.

Taking the night off for New Years and back at it tomorrow.

Happy New Years from Hawaii

Been on AA with zero disconnects for about 20 mins. All buttons including guide test fine. ??? Super solid, just won't power on with AA.
power button always start weirdly, i press it multiple times on any xo1 controller just to powerup

I would like to thank you RDC for all the posts here! They helped me enormously with my controller! As you said in some of the posts, we need to make mistakes to learn from them. So thank you a lot for my first error solving of this year and continue to teach us how to fix more and more errors ;D

Happy new year!

So, update: arcade controller is done and I am very happy. However, it will still not power on with AA.

It's weird. The second run on new boards I wanted to nail it, cause I love this project. I practiced hitting test points on the boards from run number one. I got really good and clean solders to test points on the "test" boards so I moved to the fresh board set. Also, we figured I may have damaged something around TP19 and R34 the first run.

Fresh board set goes fabulous under 10x scope and I think I am good until testing reveals same behavior. Will power on only with usb but then runs perfect on batteries only.

First, I am fine with this. Once powered on it works flawlessly as a battery powered wireless arcade controller. It is a minor thing to plug it in once to power it on and then disconnect it. Got the cord run all hidden. However, and the last part of this long post is mostly for the detectives, it is unlikely I screwed up twice and the exact same way using two different soldering techniques, creating the exact same behavior, imo.

It's something I am doing for sure, but I don't think it's soldering error anymore. Second time around had no board modification except tear down of the controller. No scraping vias or anything.

Since this is so long, sorry, I can post more on exactly what I do later (teardown and exact tp's and such) if anyone is interested. And keep in mind, I am stoked on how it turned out, so no worries.

Thank you RDC for all the info and help.

Ahhh frak, I bet I know what it is now. Where are you wiring up the Guide button at?

I'll wager you are soldering to J1p2 for Guide, if so, then that is the 'problem' and why it will not turn on from the AA pack. You need to solder the Guide button line to the right side of D27.

You are correct sir. J1pin2 guide button solder.

I was starting to think it was something with guide. Ty. Think it's fine, honestly. I may look into the diode foot solder fix, but mostly just for information on here.

Just tried the D27 solder on my first round "test" boards and it fires up great with AA only. Damn, it was pretty easy, so now I gotta do it on the permanent one.

Thank you.

Welcome. Oddly enough I have that D27 'issue' mentioned in every other XB1 controller version thread where it applies, and thought it was here also. Soon as you had the same issue on the other board it knocked that cobweb loose in the ole attic here and figured it was that.

Apologies if it was here already, I figured it would have been. Appreciate the help and I know all about cobwebs.

Permanent board D27 done and remounted and tested. About to shove it all back in to the arcade box for the 3rd time. (I love it tho,lol)

Greetings!

During the parsing of the controller from the Xbox One S (1708), the socket of the bluetooth antenna fell off (it remained in the connector tightly). I cut off the connector, cleaned the wire, decided to solder it directly, but the question is .. to which contacts what to solder?

Thank you in advance for your help and sorry for my poor english! :beg:

That wire is coax, and the pad has been torn off the board there for the center wire. You will need to make sure the trace is still there and connecting C77 and Z10, and if it is, then solder the center of the coax to either of those.

The outside of the coax can go to any spot that is ground.

So, just a quick question. The arcade controller project went so good I am going to do an expansion of the deck and want to include the "view/back" button and the triggers. Aka, drilling a few more holes in the wood deck and wiring up the 3 more buttons.

The view button looks easy at TP25 on the button board. If I want the triggers to just work like buttons just solder to TP67 and TP68 on the mcu board? Then common ground of course.

Thanks, just checking with you before proceeding.

Sorry for stupid question.

Can I use other wire (thicker) with ground, or it must be the same coax wire?

@beardawg252002 - For the LT/RT I'd run them thru a 10 to 100ohm versus straight to ground, but either way will work. https://acidmods.com/forum/index.php/topic,43204.0.html


@Artem_Slowpoke - You might be the right distance from your console for it tow work with some janky wire setup, but the wire should be coax for shielding. It would at best work intermittently using some other wire that is not shielded before it gets to the actual antenna that is on the top board.

RDC, sounds good. I read the other thread info too, ty. Also, what do you recommend for resistor as I have 10 ohm, 50 ohm and 100ohm? Can use whatever is best. Just going to put the LT and RT grounds at the end of my daisy chain ground with the resistor in line before those last two grounds. How does that sound?

@RDC hello again, so I soldered the cable (coax, took it from old notebook), center to C52, shield to the green circle. After that, the gamepad became recognizable on my PC, I was even able to connect to it, but it works well only at a very short distance. I also noticed that there is contact between the two pins (orange). Is this normal?
 
Am I doing something wrong? Thanks for further help, a lot.

The center wire needs to be soldered to where those components meet.

Measuring continuity from ground to the antenna center lead will look like a short.

It's an A1304ELHLK-T

There is no 1.23v there, it's 3.3v that is turned on/off 125 times a second. That switched voltage comes from U9.

Post by: beardawg252002 on January 26, 2021, 03:47:05 AM
Also, do u have pinout info for J8? I got both versions of the brook adapter. One is meant for the elite, and worked well, btw. I don't think this version has an independent battery and uses power from the J8, I think. ??

The other one is meant for the x1 controllers with batteries and micro port. Has its own battery power to trick the 1708 board into wired state and then I assume resends the usb commands via bluetooth or whatnot to the other consoles/pc. Pretty ingenious, simple and cheap way to use one controller on any system wirelessly.

Anyways, the SE version for elite is much easier to use and switch systems on. I am sorry if this is off topic. But kinda has a lot to do with the inner workings of the 1708 board vs the elite setup. I was thinking of using the brook SE version on the 1708 boards with some ninjaneering. It basically does the same thing on the elite and seems to force it into a wired state using the elites own power instead of independent battery?

J8 on the 1708 MCU board has I2C and some I2S stuff on there, also has a 3.3v rail and grounds. The closest for a pinout I have for it is in the 1537 thread, the bottom board schematic, and that's all subject to change as it's not been verified. I never dug much more into that port than that.

Hey guys! So I decided to attempt to install a remapping kit on my controller and royally messed up a few test points. Everything seems to be working fine except my right trigger. Tp67 came off the board. I know it is related to the right trigger. I have seen other issues with the right trigger but it worked fine before this. It seems like the controller thinks the right trigger is being held down. Is there a way to fix this, or am I boned? *I did not mess with the trigger physically at all and no soldering was near any of the components near the trigger*

If TP67 was pulled off the board then the RT line is now open and it wouldn't work. You can prep and solder to the via that is just below and to the right of it (directly under the T in TP67) and connect that via to U10p2 (U10 pin 2) and you'll get your RT back.

Well, not sure what it's really called technically, and I tried looking. Other companies must be able to buy it somewhere cause some 3rd party stuff uses the male side.

Anyways, just went with solving the problem and u can buy the female side on ebay as "xbox expansion port" and the male side is coming from old chat headsets. Then I can just make an expansion port extension cable. Making two of them cause I am making a second arcade controller from x/s controller guts 1914.

Best I can think of without knowing the name of the connection. Thank you.

Hi,

Wondering if one of the gurus can help me here? I changed out the right analog stick module on the controller and managed to lift a pad. C

Is it possible to wire in a jumper to a TP spot and if so which TP spot is it?

I have a MCU board that shorts out and will not power on via battery or USB when the antenna coax cable is plugged in. When the cable is not plugged in, the controller will power on and work perfectly via USB, when on battery it also powers on but cannot connect since the antenna cable is not plugged in.

I know it is the MCU board because I have used multiple, working power board/antenna cables that are known working. Additionally, the MCU board has no noticeable physical damage to the antenna connector port or anything else.

Any advice to figure this one out is appreciated!

Hello, Can you please help me? My xbox one S controller it's not working on battery just on cable.  have disassembled the not working and the working controller and swapped the motherboards, the problem it's with the top one with the guide button. i have measured everything and compared and not finding anything different, all resistors and capacitor have the same value. But if I hold down the guide button the controller is working normally when I release the guide button is going off. I have find a temporary solution! I have soldered an resistance between pin TP33/C11 and it's acting like the button is pressed down. The controller is turning on normal and is working, but if you turn of the controller or the console you can't turn on the controller back (to solve this, just disconnect the battery from controller and you are good to go)! Every time you turn off you have to disconnect the battery! Can't figure what's the problem. Can I duplicate the guide button using cathode side of D27 with another button? How to do this D27 and ground on another button?? Please help me! Thanks ?n advance! Hope you understand what I want

@ Greendaycolt -  I haven't seen that issue first hand here, so not sure what is causing that one. Someone on here awhile back had that same issue, and IIRC they never got back with any info about it. There would have to be something jacked up in the Antenna Filter circuit or the actual MCU to cause that kind of issue though.


@ xh0st - Issue is most likely on the Power OK line somewhere. R7, D26 or the trace from J1p9 to R7, D26, Q9. Schematic for the top board is in the first post. When you press Guide, you turn on Q8, which turns on Q9 which turns the controller on. At that point, it should 'latch' Q9 on with the Power OK signal and stay on when you release Guide.

Can't find any broken traces, i have checked all the traces and components and compared to a good working controller, also swapped Q9, broken some traces when swapped but repaired .R25 one leg is connected to Q9 and the other leg go up on a via placed on top Q8 and to J1 pin 11. Can't find any solution. TP33 ripped from board but it's the same with R25 leg. I have bridged C11 and R25 leg and it's working but still have to remove the battery after turning off the console or the controller to power it again. I don't want to give up .. if you have others ideea of what can be the fault I will check again.

A blurry image of a portion of the board doesn't really help. You have C11 bridged, remove that as well as the bridge at C12 or it's not going to work correctly to find the issue. R28 goes from Q9p3 to Ground and is not installed.

Sorry my mistake with previous post.
The bridge it's with C11 not C12. Without that bridge the controller it's not powering on. The bridge it's between C11 with R25 also my mistake in previous post.
TP33 is the same with R25 leg and it's going to J1 11 to the charging port on the other board. All the traces from Power Ok are ok

hello I have an issue with the home button. After replacing one of the analogue sticks and without removing the power board at all the home button is not registering anymore. It lights up but it doesn't do anything when pressing it , it won't turn off or turn on the controller. The controller is working fine if i connect it to the USB power cord and then remove it again (with batteries on off course). Have you got any ideas on where i should look if i messed anything up with desoldering ?.  The strange thing is that i haven't touched the power board or the home button at all.

just a quick note, i'm testing this with one analogue stick on board at the moment as i removed the other one because i'm waiting for the replacement part. Not  sure if this is related to the issue I have with the home button.

I have swapped the mcu board to my other working controller and didn't turn on. Now both controller's are not turning on.

Update: The good working controller it's back after connected by cable to console.
The not working controller back where I was on the fault with the guide button after connected to cable. I have removed the bridge between C11 and R25 and solder jumper wires from battery terminals to microusb port. The controller is working but it's not showing the battery procentage just show full.

Full size blurry image of one side, also not very useful.

The best advice that I can honestly give, is that you stop randomly connecting things together trying to make it work before it's ruined for good and never will.

Full is all of the percentage, and I have no idea what you expect it to show you having it all cross wired like that, it'll be the magic smoke before long, if it hasn't already ran off while you weren't looking that is.

You can not use the USB 5v as the AA battery source like that, and where you even came up with that idea boggles my mind on multiple levels. First, putting 5v into the AA+ terminal that was designed for 2 x AA voltage (1.5v x 2 = 3v) should not be done. Second, connecting the USB ground to the AA ground is redundant, as they are already connected on the board, so that wire is doing nothing at all.

The controller knows there is 5v there and it will run from that instead of trying to run form the AA source. Power the board correctly and look for the only issue(s) that it actually has, not problems that you are creating on top of it. If you don't have a bench supply for making a 3v source to act like the AA batteries, then get a 2AA battery holder and solder that on there, if you don't have access to that then use 2 AA batteries, some wire and tape them together to make one.

Since I can not make it out from the pics, what did you put in place of Q9?

So I have a question I recently bought an led mod for my
Girls controller. however instead of using the board it came with that's supposed to turn it on via shaking the controller I want to wire it to the main board so as to have them light when the controller is turned on, and off per shutting off. I have a decent amount of experience in this stuff but I am no expert. My idea was to wire it in along with the power buttons led?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on April 12, 2021, 05:35:34 PM
It completely depends on how the LED board for that thing is setup. If ti's designed to get 3.3v and ground connected to it, then just has an enable line to turn the LEDs on off, then yes. If you need a negative signal to turn them on, then you can use the Cathode side of the Guide LED and the new LEDs will mimic it. If you need a positive signal then you can use the Base of Q3. Again, those are only for a control signal, those are not to be used as power sources for driving who knows how many LEDs.

If the LEDs are just LEDs and their current limiting Resistors, then you need to wire them to either the 3.3v or 3.5v spots in the controller, as those are a switched power source, and even then a pile of LEDs shouldn't be wired up to those unless they are each drawing jack for current.

Hi,

I've got the following board, with R26, R28, D27 that need replacing. Do you know the values for them?

(https://i.imgur.com/m8WHIDw.jpg)

D27 - 1N4148 will prob work (according to a previous comment)
R26 - ?
R28 - ?

The board looks different to the schematic in https://www.acidmods.com/RDC/XB1/Schematics/XB1%201708%20TOP%20BOARD.pdf, so I wonder if it's a v2 of the board or something.
It's possible R26 and R28 are 25.5k and 0 respectively, but I don't know! I'm getting a multimeter to test a good controller soon.

Any help appreciated!

Thanks!

Post by: RDC on April 18, 2021, 01:13:45 PM
The schematic isn't supposed to look exactly like the board.

Those are R25 and R26, R28 is for the pads to the left of those there and it is not supposed to be installed, DNI in the schematic.

R25 = 25.5k
R26 = 0

If those things are fried then Q8 and Q9 are also suspect, if it's only corrosion on there then they are probably fine.

good night DRC

 first I want to thank you for all the teaching you provided here,

come on, I made some mistakes trying to fix my control, I tried to make a duplicate "B button" and ended up losing the TP41 solder point, following his guidance of scraping the point below the TP41 and making a jumper to the point R29 at the bottom for "Button B" to work again and for "Additional button" to use the bottom of the R29, it worked perfectly but it passed 2 days and the "Button B" and "additional" stopped working, in the intiuto of trying to solve I ended up losing the welding point on the R29.

my doubt is there ,is a solution for "Button B" to go back to work in addition to using the R29?

To get the original B button working again you will need to prep a couple of vias and solder a jumper wire between them. What I would do there is solder in a 100ohm 1/8W Resistor instead of a jumper wire, but either one will get the original B working again if done correctly. If you tear those vias up then it can still be fixed, but it will be more difficult to repair than what this is.

You can use either of those spots for the additional B button, or just install a longer jumper wire and cut it in the middle and solder both ends of that to the additional B button on one side, then the other side to ground.

ust for understanding,

For the operation of the original Button B, I connect the wire to the 2 red tips that you signaled.

to place the "Additional B" can I use one of the 2 red dots and connect the direct wire to the additional button, and on the other side I take the wire from the additional button and connect it to the grounding?

I don't think you have enough of the green solder mask removed for that solder to be making connection to the via/trace under there yet. That solder was most likely just sticking to the mask and not making connection.

Scrape a little more, gently, and when you see shiny STOP, you've hit the copper and going any further will just be damaging things. Then get the solder and wire on there and it should work.

Hello everyone,

I try to fix XB1-1708 on the RSC pad I get from 1.9V to 2.2V. I followed that line and removed c27 and r21 in case they're wrong and their voltage varied. But the PCB without joystick,  capacitor and resistor keeps giving me 2V on the TP43 and the joystick pad. I lose track on pin 80 of the MCU. Do you have the schematic of XB1-1708 MCU?
I don't know where the 3.3V comes from at TP 42 and TP43.

Thanks in advance. The post helped me a lot. I checked all the problems related to RSC and LSC but it didn't fix the problem.

Thanks for sharing your wisdom.

R21 (33ohm) must be in place or RSC will not work.

No schematic for the MCU board. The 3.3v most like comes from that line going directly to the MCU (Internal Pull-Up) so I'd suspect it has either some corrosion under there, or a bad solder joint. If a proper reflow of the MCU doesn't correct it, then I'd suspect some internal issue with the MCU itself.

Hi all

Great post as very helpful in trying to repair a broken 1708 pad!
Ive got it mostly working now using info from this thread, thanks!

one slight issue remains that the Left Stick button (LSC?) doesnt work
TP42 has lifted and the pad to the left isnt linked (tested iwth ground and moniored on controller test app)

grateful if you can advise if there are any alternate TP42 or LSC button points I can connect for button?

The proper way to repair that would be to install a jumper wire from the right side of R16 (top side of the board at the stick) to the LSC pin. Then another jumper wire from the left side of R16 to pad 55 of the smaller MCU board there, where it attaches to the main board. Alternately you could just go from the LSC pin to pad 55 and see how that works first.

I have an MCU board that works perfectly with wired connection, but on 2.4Ghz wireless it will only connect when the controller is within a few cm of the console or wireless adapter (it loses connection outside of this very small range). I?ve verified it is an MCU board issue and not anything to do with the antenna cable or power boards. Tried reflowing the MCU/RF module but the problem is exactly the same. Any advice is always appreciated!

Sorry when you say pad 55 on small mcu - is that a reference to the board with heat shield on it?

Great work with schematic.
I figured out ICs U1-U3.
U1    "IAEBD" is MP2161GJ-Z buck converter,
U2-3 "IACMD" is MP3414DJ-LF-P boost converter,
"I" isnt part of code, its mark where is top of IC,
and last letter (here "D") is some sort of production year mark.
Hope someone will find it helpful

Yeah, noticed after posting, just rushed to"share" my knowledge after seeing schematic ;)
I may come to right place for advice, got problem with controller.
Its totally fuctional with usb plugged in, but when i try to turn it on (with new AA batteries) it works as long as i hold power button down. I can connect via BT, play game etc. but when i release button pad just turns off instantly. My bet was that battery charge sensing is somehow broken and power button bypasses it. But after connecting to PC v/BT Game controller tester shows fully charged battery.
Sadly i dont have acces to PnC pack, but it looks like everything is working properly and software is flawed? Any thoughts what could i do?
Im aware of simillar problem in this thread but diffrence is that my pad works on batteries, just i have to hold X button whole time :/
Thanks in advance.

No worries at all.

99% of the time the issue is on the Button/Power board. Make sure D26 is not missing or there is some issue around the Q8/Q9 area of the board as that's where the 'latching on' takes place. Pressing Guide turns on Q8, which turns on Q9 and the controller powers up and then the MCU puts power onto J9p1, which keeps Q9 turned on after you release Guide. That's what isn't happening, so there is either an issue with D26, R7 or the traces and vias that connect that all together. That last 1% of the time, there is something going on with the MCU not sending that signal, broken trace or just the MCU being screwed up, but most times that issue is on the top board can can be sorted out.

There is the actual DD switch to consider as well, but that's about it. U4 can fail in that manner locking up only 1 button but otherwise functioning normally.

Hello.

I was trying to fix my drifting controller by replacing the analog stick but I ended up losing a good part of the solder pads of the X axis. There's just a tiny little saved part of the pad for each of the pins but doesn't seem enough to make contact for every of them since the X axis doesn't trigger any changes whatsoever when I move it.


Is there anything I can do now in order to fix this mess?

Thank you!

Hi! My first comment here. I have used the search feature but I didn't found any problem like mine (only this https://www.acidmods.com/forum/index.php?topic=44500.0 and some replies here about *other* parts).

I was trying to repair microusb port in my bud's 1708, but accidentaly I've blown D17 with an hot air. That thing is so tiny... I can;t find it anywhere in the room and I was literally crouching with flashlight, checking every black dot on my floor. I am so frustrated... Can I short pads or is this part vital? If it's vital, what are the specs?

Thanks so much to anyone who will respond and I hope, I did everything well in terms of forum rules (I've read them btw).

Never short the pads where any component was installed, unless some doofus specifically tells you to do it, and why it can be done, and even then you should check to make sure that it's an acceptable repair. In this case, no, not at all, as you would ground out the D- USB data line.

D17 is a protection Diode for the D- line, but it will be alright with it missing.

C6 has nothing to do with the AA voltage, it's on the 5v rail that comes from the USB. U1 is only in there to knock the 5v down to 3v for U2 and U3 to use. If the controller works on USB, then U1, U2 and U3 are all fine.

Use the schematic and check everything in the entire bottom right quadrant of it. The AA power gets to U2/U3 from there, L1, Q6 ~ Q9 and all of the support components around there.

Post by: will38uk on September 12, 2021, 05:10:55 PM
I just wanted to write a few words of appreciation for this thread and in particular RDCs comments without which I probably wouldn?t have fixed my controller. 


I was a complete novice to soldering or electronics, but with the advise within this thread, was little by little able  to understand how the potentiometers worked , what test points are for, how to use a multimeter , and how could put in my own jump connections to restore connectivity lost by damaged pads.  I didn?t initially understand there were pads, that I had damaged them and how to work around the problem of the damaged pads.

I have two controllers and have fixed the first one and optimistic should be able to fix the second.

First controller - I had unbeknown to me damaged the pads.  I didn?t even know they were pads lol .  I thought just having pins poking through board and a bit of solder meant it was making contact and couldn?t understand why not working.  I finally got working by soldering from the soc to the middle pin , as well as jumping negative and positive from the pins of the x axis which was working.  Prior to this I had unsuccessfully due to my clumsiness and inexperience bodged the test point pad and the c22  on other side of board.

Second controller - I can see that one axis doesn?t have negative positive charge and test point showing nothing with continuity so will jumper these .  The other axis it?s just the middle signal pin needs jumping to the appropriate test point .

I will mention this as may prove helpful to someone,  I accept that if you are confident at soldering and what you are soldering to then this step is unnecessary but for other novices something I found helpful was I connected up the controller to a permanent ?switched? battery  power.  I did this by digging out an electronics set I had as a child, popping in 2 aa batteries , figuring which pins tested as giving 3 volts ( also check polarity ) and then soldering the wires from my electronics set to the power pins in the Xbox controller.

This meant I could

A) test for voltage on the board ( which required controller powered on ) much easier !  Prior to this I was dangling a battery part from pins and trying not to jiggle to much .

B) likewise  quickly switch off the power, do some soldering and test , without having to either struggle to dangle the battery pack onto the pins and hold controller to the side, or put the plastic back cover on , then put batteries in and still trying to hold the cover in place so don?t loose contact

I should add as well that if you are planning to repair lots of controllers then this could be handy to keep this half of the controller circuit board to mix and match with the other board that the analogue stick sits on

EG2 there is some type of TVS Diode. It will work fine without it and that would not cause any issues with LT/RT.

Use the schematic for the MCU board and look around U9, U10 and U11 for the issue with them.

Thanks a lot for your answer. Power consuption of Controller is about 120-150mA. Is it normal or not?

Also 304 hall sensors have ~2Ohm resistanse between one leg and ground. Other leg connected to ground. And there is no any voltage on 304 and they not heating.

But main CPU heating about 35-38C (is it normal?).
Also diode D22 heated up about 40C


Controller detected by Win10 fine, but triggers doesn't work
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on November 11, 2021, 12:49:08 PM
I have no idea what any individual component temps for normal operation would be.

U9 is a 3.2v Regulator that is turned on/off 125 times per second to supply voltage to the Hall sensors, U10 and U11. You really need a scope to see what is going on there, but a decent DMM would still measure something there.

U10/U11

Pin

1 - Around 1v
2 - Around 0.12v, gets lower the more the Trigger is pulled
3 - GND

If those voltages are not there, then check the voltage at R38. It should be around 0.3v and that will mean the MCU is telling U9 to turn on/off and then the issue would most likely be with one of the decoupling caps between U9 and U10/U11, namely C32, C33, C35 or C37.

Guys, I'm a Hobbist and I fix my own consoles. I went to clean my friend's Xbox One controller, which had spilled some water, and after that the controller started turning on and off by itself. The day after the event, I opened it, cleaned it (there was a lot of cat hair inside and almost no water) but at the time of reassembling, I noticed that when I disconnected the cable from J1 point, the point detached from the plate, getting stuck in the cable.

No need for cross posting.

That's the connector for the antenna, and without seeing what you did exactly no one is going to have any idea how it can be repaired, or even if it could be. If the pads were torn up with the socket, then you'll most likely not get that repaired and working 100% as the RF signal will be quite a bit screwed up from how it was designed to work.

The second spot is just a ground, and most of it is still there, that one is fine. The first one though you'll need to solder a jumper wire to restore the RB trace.

Install the new RB Tact switch.

Solder up the 3 spots, or 2-3/4 if you want to be picky about it, that are still there.

Solder a jumper wire from the lead that has the missing solder pad down to TP20. It's just to the left of U4 there, same side of the board. Use as small a wire as possible and make sure it doesn't get pinched anywhere when you put the shell back together.

I'm sorry if I didn't understand correctly. English is not my native language. I'm sorry for this  :wacko:. By "solder a jumper wire from the lead that has the missing solder pad", did you mean I have to solder the male end of a jumper wire to the terminal of the RB tact switch (the terminal that goes into the hole with the missing solder pad)? I thought lead was a part of the solder. Sorry for my confusion. If you can explain this to me, I'll be grateful.

I did some quick search on what jumper wires are. Do I have to use a male-to-male jumper wire, a male-to-female, or a female-to-female jumper
wire? I searched in this website: http://blog.sparkfuneducation.com/what-is-jumper-wire
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on December 21, 2021, 09:33:15 AM
Lead (pronounced led) is a metal.

Lead (pronounced leed), or pin, is the metal part of a component that sticks out that you solder to. A typical IC has multiple leads, that RB Tact switch there has 4 leads.

Jumper wire is just a generic term for any kind of wire used to 'jump' over some bad spot. Those jumper wires are for use on a breadboard. All you need is a thin piece of wire, no ends on it. Solder one end on the RB lead there at the missing pad, the other end of the wire then goes to TP20. 30awg Kynar wire is what should be used, and do turn the heat down some, as you don't need much to solder to that small TP20 spot. Tearing that off the board will put you in a lot more difficult repair to make.

Thanks for explaining this to me. I really needed to learn it.

I don't have a soldering station to control the temperature of the iron so that it doesn't get too hot, but I do have a 25W iron. Is it "cool" enough not to damage the TP20? I'm afraid of damaging this board even more.

Edit.: I looked a bit more into it. Can I use old headphone wires as jumpers? I have some lying around, and maybe they could be used, idk.
Edit.2: Also noticed some jumper wires have rubber covers, while some don't (they're just bare wires). Which one should I use on this fix?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on December 21, 2021, 02:34:33 PM
If you can not turn the iron down some, then learn to leave it on the work for less time. That is the more important thing to get the hang of anyway, and you are only going to get better at that with practice. Expect to tear up plenty more stuff if you want to get better at not tearing stuff up, that is the only way to learn. Anyone that tells you they have never torn up a trace, lifted a pad, torn out a thru-hole plating or knackered a via either has never worked on any PCB ever, or is just straight up lying. I have forked up my fair share of things, but as you keep at it the mistakes get fewer and farther apart, but you will never get it right every time, all the time, and that's fine.

Headphone cable could be used, though it is an enamel wire type, that is to say that it has a very, very thin coating of enamel (paint) over it and that is the insulation for it. Even if it looks like it is already copper, there is a coating of enamel on there. Most times if you try to solder to that, it will look like it attached, but that is just the solder holding onto the wire mechanically. You have to tin that kind of wire first, and that is to burn off the enamel coating so you get down to the copper wire in there so the solder can stick to that to make the electrical connection, which is what you are after.

The different types of insulation on wires you can spend all day Googling. What you do not want is any bare wire in there, as that will just be asking for it to connect to places you do not want it to, aka shorts. You also do not need any wire that has a thick insulation as it will just be pointless and get in the way. Again, 30awg Kynar wire, also called wrapping wire, is what most people use for that kind of repair there.

However looking for how to detach the bottom board from the upper one, I found too many things could go wrong, so I thought of another thing, and I don't know if it's possible. Maybe I could scrape the trace a bit and try to fix the connection like in the following video, at the 9:34 time stamp?

https://www.youtube.com/watch?v=AR0lb7YI0v4 (at 9:34).

As I still don't know how to attach images in this message, I'll put a link to another document I made, with some images related to my question: https://docs.google.com/document/d/1oNijNMwqyyXVqm3EnrFbY9udNF-CH77DQTsRdemjEmk/edit?usp=sharing.

Is the trace I put a red circle on the one I should scrape? I actually don't know which trace connects to which solder pad, so I'm sorry for asking these basic things. It sounds a little scary, but I want to give it a try maybe, if it works as well. My friend said he has a friend who has a lot of experience with soldering smartphones that maybe could orient me with the scrapping part, since I could pretty much ruin it.

Thank God it worked! Thank you so much, @RDC. I finally did it! I used a lead from a wire LED I bought very cheap and used it as a bridge between the RB tactile switch lead and the part of the board I scraped. Could someone please tell me how to insert images here, so that I can help other people with the same issue? Every time I try to insert an image, this appears:

Those are just the image tags, so that the link to the picture you place between those tags will make the image show in the forum here. You need to have the image uploaded somewhere first, like Google Photos, Imgur, etc, etc, and then use the link to the image. Also do try to keep them to a decent size, not everyone runs a massive monitor.

I'm planning to use my xbox one controller (1708) for controlling remote controlled vehicles (in my case an ROV), but I'm not entirely sure how to read data from the controller with an Arduino. Can I leave the controller circuit boards intact and power it from the battery and just tap into the I2C bus for reading the button presses and use test points for the joystick axes? Or do I have to cut any traces to some of the onboard chips?`

I hopew this isn't considered off topic and would highy appreciate anyone taking their time to respond!

Post by: RDC on December 28, 2021, 05:47:07 PM
A really nice way to go about it would be to use some kind of wireless dongle so the controller isn't even touched, but I could probably get a snake to juggle before I could pull that off.

Reading the data from the controller in a 'brute force' kind of way like that is pretty straight forward, but should be step 2 in your process there if that's how you plan to go about it. How are you going to keep the controller powered on to read any data from it? If you are running it off the battery pack or AA, it's going to be in wireless mode and looking for something to Sync to, and when it doesn't find anything it will turn itself off. You might be able to get around that by faking the Power OK so the thing stays powered on, but I have never tried that and even if it worked have no idea if the thing would continue to function correctly as the MCU could be setup to time out there or who knows what.

Powering it from the USB connector kind of bypasses that and will keep it running and spitting out data as that puts it into more of a wired controller mode. Then you can tap onto the controller and read it, but then you either need a 5v source or jerry rig the controller up so it thinks it's on 5v when it's not, and that's honestly more of a pain than just running it from some 5v source.

You can tap onto the I2C to read everything except the B, LSC, RSC, LT, RT and Sticks, as those are all on the MCU board. Reading the Triggers will be a pain all their own if you plan to use those also. If the I2C method becomes a hassle, you can always just tap onto each of the button lines that you want to read directly instead, though that will take more IO than using the I2C method. Using the I2C you'll get up to 12 buttons using only 2 IO, whereas directly wired you'd need 12 IO for the same 12 buttons.

What chip is responsible for making the 3.3v rail. Based on your schematic I would assume U4. I am asking because I have a board missing the 3.3v rails it puts out just a little over .1V, but it does have 5 volts coming into the board
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on January 01, 2022, 08:54:32 AM
U4 is the IO Expander. U3 (U3T in that schematic, I need to update that thing) is responsible for making the 3.3v rail.

If you are running it from the USB cable, that 5v does not go directly to U3. The 5v first goes to U1 (U1T) and is knocked down to 3v, then that 3v goes to U3 to make the 3.3v rail.

Post by: RDC on January 01, 2022, 12:19:09 PM
If you are testing the controller as a complete unit, that is both boards plugged together, there might be some short on the 3.3v rail of the MCU board and that is why you will not have that voltage.

You can test the voltages of the top board all by itself to make sure they are all working. Just unplug it from the bottom board, then plug up the USB cable and all 3 of the voltages that it makes should be there.

U1 = 3v
U2 = 3.5v
U3 = 3.3v

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on January 02, 2022, 10:32:06 PM
Not really much on that 3v/B+ rail. You could remove U2 and U3, then test and see if U1 is back to 3v, if it goes back to 3v then it's one of those chips or something on their outputs. If it stays low it's a decoupling cap or some issue I haven't seen before. You could also inject 3v on TP34 and see what gets warm first.

Well, something odd happened. After replacing my RB tactile switch (as posted above), my controller only works when connected to the console/pc with a USB cable, but it won't work using AA batteries anymore. It doesn't even turn on. Works fine with a cable, though, as I said. Any ideas on what could've happened here? I left the controller in the same state shown in the pictures I posted above and only repaired the RB (didn't even touch on anything else).

Can't see everything in those pics. Make sure you didn't put the AA battery posts behind the shell when putting it all back together and that L1 is still on the top board.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: student705 on January 07, 2022, 08:55:11 AM
The issue had to do with the shell not fitting correctly.

Turns out it didn't have anything to do with electronics. While replacing the RB tact switch, I accidentaly burned/melted and deformed that plastic piece that fits in the sync button with the hot soldering iron  :sadno:. As a consequence, the shell wasn't fitting correctly to the board (the deformed part was preventing the shell from fitting completely). So make sure you guys remove plastic pieces that get in the way before soldering anything so that you don't make the same mistake I did.
As I had deformed only the right side of that plastic piece, and the left side was still intact, I just used a knife to sort of carve the right side so that it became more similar to the left one. Well, it seems my carving abilities are somewhat good, surprisingly, because after making one side similar to the other again, as it should (since both sides are originally symmetrical), the shell fitted correctly again and my controller started to work with AA batteries. :tup:

So after replacing r18 and still having no change, I decided to do what I should've in the first place and make sure U1 is being told to turn on. So naturally next thing is to check for 5v at D23 and I have about a volt. I go all the way to the micro USB connector still only about a volt. My best guess is something has to be shorting the 5v line to ground now to find it

It's just a bulk decoupling cap for the 3.3v rail. Anything from 68uF to 100uF would do, and honestly you could probably even leave it like it is and not have any issues.

It's a Common Mode Choke on the USB data lines. There are most likely a few out there in that size that would work fine as a replacement, but the only way to replace it with the exact same part would be to get it from another controller board.

It will just not work wired, console or PC, if that is left out, but it will still work wireless fine. You can bridge the connections to get the USB data lines back, just be aware there are 2 traces there and it will be 2 wires to jumper that correctly, don't go bridging just any of the pads together there. It's basically just 2 Inductors in one.

Hi guys,

I've got a couple of questions regarding spares, I've done a lot of searching, but can't seem to be able to find clear answers.

1. What's the exact model number of those Alps analog sticks? Any chance of getting separate genuine potentiometer spares? Do you know of any better spec sticks/pots that would fit 1708 (I mainly mean durability/lifespan here, performance can't be inferior tho)?

2. Any chance of getting genuine bumper switch spares? If not, do you know of any reliable replacement?

3. Do you know where I can get a good quality button pad for 1708 (I live in the UK)?

I appreciate your help.

Hi all, I m going to add extra LSC and RSC button to my controller.
 
my plan is connect the MCU Board TP42(LSC) and TP24(GND), TP43(RSC) and TP22(GND) to a push buttom (simple 7mm Momentary Push Button Switch Round Flat Button)

my question is: do I need another 33ohm for this?

many thx.

Post by: RDC on April 21, 2022, 10:08:23 AM
It's not really that necessary. If you solder to the LSC and RSC solder joints at the stick instead of the TP spots though you'll be going thru the existing 33ohm and can keep it exactly how the original LSC/RSC work.

Not sure what you're seeing that looks suspect. An earlier/later run of the same version board or one made at another factory might have some subtle differences where they place that info or tweak something, but that doesn't mean it's fake. Knockoff controllers have massively different hardware inside and look nothing like the official ones.

Post by: Mackerel on June 09, 2022, 07:10:04 AM
@RDC and others. Thank you for your helpful posts. I accidentally ripped off the pad of my RB button, but successfully soldered a jumper wire to TP20 using your photos and advice. I didn't know there was a way to bypass the original pad to another pad located somewhere else. This was the 5th time I've had to replace my RB button. I hate this thing. Hopefully, the switches I bought from Digikey will last longer than another batch I bought elsewhere. Such a crapshoot of suppliers.

I have some questions:

1) Is it okay to stick the end of the wire through the through-hole of TP20 and solder it like that? The reason I ask is because TP20's pad looks different and seems like there's not much metal exposed to adhere solder to, so I ended up just holding the wire on top of the hole and soldering to the extremely small amount of solder that was already there. Not very strong, but it's holding.

2) Given how small TP20 is, would flux paste actually help make it adhere properly? It just seems like overkill, but I don't know.

3) Would conductive ink work as a connection from a new RB button's lead to the trace and be faster/better solution than a jumper wire? I'm considering getting some and trying it out, but if anyone else has some experience with it, I'd appreciate advice.

==============================

Things I noticed for anyone attempting the same thing:

(It seems I just didn't have the J1 connector connected securely)- There is a metal "spring" or ribbon on the second board (with thumbsticks) that must make contact with the first board's (with bumper button switches) surface contacts to enable the controller to power on (power cord is on the first board). I was scared that I had shorted something because the controller refused to turn on, but I realized this connection must be completed with pressure exerted from the screws. It was strange to me that the controller would not power on when disassembled, but would power on once I reassembled it with the outer shell's screws.

- Speaking of the metal spring above, if you do solder a jumper wire to TP20, it will likely have to be placed between the sandwiched boards, and therefore must be placed or shaped in a way that avoids getting sandwiched between the metal spring and it contacts on the first board.

- It is unnecessary to remove the bumper plastic (what you actually press when the controller is assembled) to solder bumper buttons. Just leave it alone, unless it's really getting in the way.

- It is unnecessary to desolder the rumble motors or its wires from either board. You can just unscrew the second board and gently move/rotate it out of the way to reach the first board's leads. But, of course, this might weaken/break the wires if you're not careful, but it's not like I've been super gentle with them and it's been fine.

- The torx screws for the second board are smaller and easily stripped (both the plastic post they screw into and the screw's notch). I stripped one side's post and it no longer screws in properly. :censored: Microsoft for these weak ass screws.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on June 09, 2022, 09:10:27 AM
TP20 is just a pad, there is no hole or via under that, and if you end up tearing that off the board you'll find soldering to the pad of U4 to get it going again a far bigger challenge.

The vias are full of solder mask, so you're not putting a wire thru any of them without using a pin vise and tiny drill bit to clear the hole first and then removing the solder mask around it to expose the copper.

If you aren't using 30awg size wire, you should be, and then use some hot glue to secure it in place after you have it where you want it. Do not glue right on top of the solder joint you made, but back from the joint just a little bit.

Good solder flux makes things go a bit smoother, depending on what you're soldering. For sticking a wire to a TP spot on that board, it's not really going to help out that much, and if it does then the solder you're using is most likely not a good rosin core type.

Conductive ink is alright, though it's better used where you are trying to keep the repair as low profile as possible, where a bunch of wires to make the repair might cause issues. It's also no good for trying to rebuil the eyelet where the RB lead goes, the wire end wrapped around that once is a far better option.

Not sure why you're going from the RB lead to TP20? You can go from the RB lead to the bottom of D3 and C29 for a much shorter run.

The large spring contact is just another ground, and there are already 2 ground connection in the J1 connector, so as long as that is plugged in that spring contact isn't really doing much.

Post by: Mackerel on June 09, 2022, 11:52:48 AM
This is the first time I did a jumper wire for anything and I'm not very experienced with PCBs, so I didn't know it wasn't a hole or that I could use the pad beneath D3/C29 either. If that info was posted, I missed it.

I have no other "just wire" wire and I'm not exactly interested in spending time getting wire from some random old earbuds, let alone buying a spool of wirewrap that I will almost never use again. The wire I have is probably around 0.5mm thick, about double of 30awg. Is there a reason to use 30awg wire?

For using conductive ink, I'd rather have the RB tactile switch easily replaceable, since it constantly wears out first for me. If a fix doesn't require setting up for soldering, which I extremely rarely ever do, and it's generally faster to use ink, I'll do that instead. As for glue, it makes sense. Not sure if I'll do that though.

Edit: Also, I see. I suppose I just didn't have the J1 connector connected properly at times. Again, appreciate the advice.

Hello, first time posting here.

I apologize in advance for asking for help. I've read this post's first page and other to guide me but each time i find a new thing to try, it kinda fails. Also, the thing is i started reading it after i butchered my controlller's pcb. :censored:

My micro-usb port started to fail so i decided i would change it. Ripped the traces off. Tried to do some jumper wires and sometime ago i managed to make it work for a while, but then it started failing after an half an hour, in the end, it all went downhill from there, but at

least i learned a lot (from making jumper wires and properties of electronics).

Here are some photos of the pcb. All i have is the ground left (also cr1 just fell when tried to repair one of those times).

And here is a replacement "upgrade" USB-C i bought to use instead.

They have nothing to do with each other, so you have caused some kind of collateral damage. Can't make out much from that board pic. Check C38 for a short and make sure R42 is 100ohms (both are top side just under the stick) and make sure TP68 is not shorted to ground.

Thanks so much for the quick response. I?m pretty new to all this fun stuff so bear with me. Checking with my DMM black on TP21 (grnd) red to TP68 I?m getting 3.3v. How do I check R42 and C38 won?t they not get power if it?s not connected to the other board? I?ve spent the majority of this Sunday working on this and as frustrating as it?s been it?s also been a pretty fun hobby for the day! Appreciate all your contributions.

Also curious how you would replace one of those small components (sensor, cap, resistor) I can?t see any solder to remove or anything
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on July 11, 2022, 09:23:04 AM
Typically you use a hot air setup for reworking most of these kinds of components, and you can see the solder on the ends of the Resistors and Capacitors.

Do not have the controller powered up when checking for Resistance values or looking for a short with the meter set to Ohms.

TP68 should never have 3.3v on it, and if it did then the LT would act unpressed. If it in fact does does though, then something is shorted and/or really knackered somewhere, because that measurement is conflicting with how it would act.

Plug up the USB cable and set the meter to DC Volts and measure the 3 pins of U11 with respect to ground, aka black lead to ground, red to check each of the pins.

Hey RDC thanks for the response , I double checked TP68 and it?s showing 3.3V and doesn?t change whether I push the trigger or not .

At U11
Point 3 gives me 3.3V
Point 2 gives me 3.3V
Point 1 gives me 2.3V

Well, you're not doing something right, because point 3 of U11 is ground, there is no way on earth for that to measure 3.3v.

Did some cleanup on the board a little , saw a little splash under my jumper so got that out. I?m hooked up to game pad tester and upon connecting nothing shows pressed, if I press right trigger it activates both left and right trigger but when I release RT shows unpressed LT shows pressed. Disconnect, reconnect to GP Tester press LT and release and LT shows still pressed.

You?re right, I?m a big dummy 😂 I was using TP9 as ground because it?s right beside TP21 I got them mixed up.


TP68 shows 0V

Point 3 gives 0V
Point 2 gives 0V
Point 1 gives 1V

I just checked the other side , looks like TP68 is getting 0.10 and the U10 port 2 has 0.10 as well
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on July 12, 2022, 06:47:22 PM
You really need a scope to see what's going on there for sure, but the meter should measure around 1.3v on pin 1, then 0.3v on pin 2 of U11, with the magnets in the Triggers away from the Hall sensors. You can also measure U10 for comparison, as it's the same Hall sensor, just for the RT instead of LT.

If you have around 1v on pin 1, and 0v on pin 2, then that suggests either the LT line is shorted to ground somewhere, or the Hall sensor has gone bad.

Hello!
I'm kind of new to modding, so forgive me if this is basic, but I was wondering if there is a way to completely block the analog sticks, I already removed them, but theres still some movement on the pad tester.
Thank u for this post, this is being really usefull for my arcade stick mod.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on July 18, 2022, 08:07:28 PM
With no POTs installed the Analog lines are now floating and that will cause all kinds of issues.

360 controller shown, but it works the same for any that have the POT style sticks. Resistor value isn't super critical, just make sure they are all the same, 10k for all of them will work fine. They do not have to be SMT, they can be thru hole 1/8W or 1/4W or whatever really.

Measure the Resistance of TP68 to ground, then TP67 to ground and compare them. They should be close to the same. If TP68 is much lower, then suspect C38 (470nF) or a short on the LT line from U11p2 to the MCU or an issue with the MCU.

The 1708 schematic is on the first page.

LB and DU are on the IO expander of the top board, so there is no LB and DU connections on the MCU board, all of those top board buttons are done over an I2C connection to the MCU.

You said the problem is not on the button/power board, but not how you came to that conclusion. Every time I have seen, or anyone on here has had an issue with more than one button not working, U4 has been the problem, and that is on the top board.

Hello, I just registered so I apologize if I made a wrong first step, anyway I have a friend of mine which gave me his Xbox one controller to fix because the RB button is always working, I thought it was a faulty switch so I proceeded to solder a new one on the board but the problem persist, so I even tried de-soldering the switch and test the controller without the RB switch and it still register as active! I don't know where to look at in the circuit scheme to find a solution, any ideas? Thanks for helping!

Post by: RDC on September 16, 2022, 01:00:30 AM
You can check the Resistance across the RB button pads, and that should be a couple of Meg ohms or more. If the Resistance value is low, in the Kilo ohm range or lower, then it could be C29 or D3 on that board is bad. Remove both and test again, if the Resistance value is till low then I would suspect U4 on that board is bad.

I tried testing the apparently faulty pads and I get different values between RB and LB, LB have much more ohm than RB, so how can I exclude others components?

Post by: RDC on October 08, 2022, 01:27:19 PM
No idea where the break is, so no idea where you would need to jumper it. If TP25 does not go low when you press View, then follow the trace back from TP25 to the view button and find where it is open. If TP25 does go low when you press View, then check the trace from TP25 to U4p15. If the trace is good then suspect U4 is bad.

Incorrect. It has pretty much the same outer shape as a miniHDMI connector, but that is a 19 pin connector. The one in the XB1 controller is only a 12 pin. I haven't gone looking for a mate for it, so hard to say what it is exactly.

Sorry to necro this, but I've been trying DESPERATELY to find a male plug for this. Do you have any new information or places I should be looking?

I am designing a touchpad attachment and I'd rather not have to include a separate battery. I really only need power and ground. I of course have already tried forcing a mini HDMI plug (lol that didn't work). Right now it's looking like my only option is to buy cheap accessories to dissect them for the plug.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on November 03, 2022, 05:07:47 PM
If the Touchpad interfaces with the controller, why not run the power/ground lines with the rest?

I've honestly never gone gone hunting for that connector mate, and if I did I'd probably start on eBay or AliExpress for it. After that I'd just look on eBay or even yard sales for some either used or cheap peripherals like you mentioned, at least then you'll know it's going to plug in there.

The Guide button line on the bottom board is pretty much a straight shot from the connector to the MCU. It would have to either be a broken trace, bad solder joint at pin 11 of the SoC board, bad trace on the SoC board, bad solder connection at the MCU chip or the MCU itself is bad. J5p2 to SoC board p11 to MCU K1

Thanks @RDC as always for your help.

After studying your schematics I finally worked out where K1 was !

I did a continuity test between J5p2 and SOC p11 and got a connection.

The MCU (ARM chip)is under the metal shield to test K1 ?

MCU is a BGA chip, you might just barely be able to get at K1 with a really fine needle for a test, but poking the thing could make it connect and then open back up after removing the test probe which will give you a false measurement.

C54, the large one, is 10uF. The rest not 100% sure, but are most likely 100nF or so. It should work with all of those missing though, as they are just decoupling. If those were knocked off or even accidentally desoldered with hot air, then it's hard to tell what else was done to her.

It did not turn on without one capacitor (to the right of the large C54). One side was soldered off. I just pressed it and the gamepad was able to turn on.
And I decided to return all the capacitors.

C55 is to the right of C54 and is just a decoupling cap on the 3.3v rail, wouldn't matter if it was there or not. Pressing on it probably made some other connection somewhere.

btw to of my controllers, when i connect them to usb supply, some kinda noise like whistles comes from my board. idk where that comes or that is due to my left analog stick problem or not

i checked all of my jumpers with multimeter and they are fine

As far as the 'whistling' goes, look around the DC-DC converter that does the USB 5v to 3v, U1. Could be that Inductor is going bad, it has some other iffy part or it's getting loaded down wrong.

No AN+ to LSY = full Up movement.
No GND to LSY = full Down movement.
No AN+ to LSX = full Left movement.
No GND to LSX = full Right movement.

Make sure both POTs have the AN+ (1.8v) and ground they need. AN+ is on TP103 there. Also make sure none of your jumper wires are touching each other or any other solder joints in there.

Have to be more specific with part numbers, because M$ didn't keep them in check between the boards.

C22 on the bottom board could case only LSY to go full up.

C22 on the top board is a decoupling cap on the 3.3v rail.

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on December 18, 2022, 10:21:58 PM
See if that 1.8v changes with USB connected versus wireless and battery powered. It shouldn't, and if it is putting out 1.5v all the time, then that's going to do something, but I have no idea what. Only the sticks and then the MCU uses that voltage as a reference, but there is also 1 pin on the MCU that measures that voltage thru a divider, so that 1.5v could be making it act that way, though I have no idea why it would make just 1 axis act funky over wireless and be fine on the PC.

No way I can replicate that here, so best thing to do is start comparing that one to one of your good controllers and see what doesn't measure the same between them.

hello,

I kinda messed up the solder pads when desoldering the analogue stick on one side. As a result the solder won't become attached to anythig for some of the pins of the new analogue stick. I want to try and restore the connection with very thin wiring but i'm not sure what to connect exactly. For some of the pads its obvious how they connect to the rest of the board but for others i can't understand what to restore. Can someone draw the connections ?

here's the damage done. What should i do with the ground connections ? I have attempt it to connect the analogue but as you can imagine it doesn't work at all :(

(https://i.imgur.com/oIXRG4u.png)

I drew the following. GREEN is Ground (if i'm not mistaken) and RED pads need to be replaced and connected to the wiring again. My guess is that GREEN doesn't have to be soldered necessarily at all points.

Hi, i was wondering if i could get some advice on where to start with repairing a few of my controllers instead of having to spend $'s replacing them.
Im not completely tech minded but have succusfully replaced a couple of analogue sticks in the past but dont know where to start with these issues so any helps greatly appreciated :)

Controller 1 ) rattly light rumble

Controller 2 ) lsc not working when pressed

Controller 3 ) left trigger slightly activated on its own

I thought i would start with controller 1 believing it to be the easiest by just changing over the motor however after changing the motor for a new one the rattle is still there when activated?
I have changed it with a know working one from one of the other controllers also but the problem is still there? The motor spins as it should but just makes a rattling noise.

I do have a multimeter at hand but am no electrician by any means so if points need probing a bit of guidance of what setting on the meter i should be using would be really helpful and if the info is already a posted a point to the right page if you could.

TIA
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on January 19, 2023, 09:34:17 AM
Any rattling is most likely the motor not being held in there properly or something else in the shell making that noise. If the actual motor is making a weird noise, then the driver or support components for it could be suspect.

Hi RDC,

A friend attempted a repair on his 1708 controller with stick drift, the analog stick was replaced but now the only things that work are the center xbox button, analog sticks and triggers. now it is my problem, I am wondering if the sloppy soldering has killed the U4 io expander, whether you see anything obvious in the pictures or any advice you may have. i am wondering if i can get a TSSOP24 version of U4 and manually wire it in place of U4 to repair the io expander functionality as i dont have the capacity for hot air. I am also wondering if U4 is PCAL6416A or TCA6416RTWR as your schematic and post seem to contradict each other

https://imgur.com/a/y0Y3qQK

If you have any advice at all that would be super helpful! thanks

Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on January 22, 2023, 11:57:49 AM
U4 on the top board is the IO expander, U4 on the bottom board there is for the LT and Heavy Rumble.

No contradiction, both of the aforementioned chips are 6416 IO expanders. One is made by NXP and the other is TI and either can be used.

The soldering is just a shade on the heavy side, but I don't see anything at all wrong with it or around there, also, there's really nothing over there that would mess with the IO expander. I'd suspect and issue on the top board for that kind of no button problem first, but wouldn't rule out an issue on the bottom board. Give the connectors on both boards a good look and see if any joints are broken, and check the top board for any missing components. The Reset line to that U4 on the top there can go open and will cause it to not work also.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: Prophet254 on January 24, 2023, 05:38:52 AM
Thanks for the advice RDC!

I see now the correct U4, I did think there were not very many connections! Haha. I have been over the whole board several times and couldn?t find anything out of place, on the top or the bottom board. No issues with the connector or any traces heading away from them. I removed the analog stick and checked all the traces underneath for damage. Reset on the io expander is ok also.

I saw that the B button runs directly into the SOC and not through the io expander so after tracing back to the pad from the soc I have come to the conclusion the soc has been semi-killed as you would expect the b button to work at least as it is a direct input.

Anyway, all this to say thanks for the advice and I give up!

Post by: RDC on January 24, 2023, 12:57:49 PM
Yeah B, LSC and RSC are all 'direct' inputs to the SOC. They each have their own Resistor they go thru before getting to the SOC. For no buttons, including B, to not be working while the Sticks and Triggers are working is pretty odd. Do LSC and RSC work?

The RSX-axis line is shorted to ground, or the more likely issue is the 1.8v is not getting to the RSX POT.

I have 2 xb controllers, first has lost allot of pads, tried to do jumper fix but thumb stick is still dead.

Second pic, one jumper, the jumper has the thumb stick working but the other thumb stick (no work on it) is dead. Check board, can?t see anything bridged or missing, need voltage test point I think.

The RSX-axis line is shorted to ground, or the more likely issue is the 1.8v is not getting to the RSX POT.

   O          O
G                   B  o
Y
V                   B  o
   O          O
      V X G

G = Ground
Y = 0.958V (same on TP63)
X = 0.007V (same on TP64)
V = 1.794V
If you mean V is RSX-pot I have 1.794V. Changed left stick but same result.

EDIT: I saw that someone soldered a jumper instead of capacitor C24, I removed the jumper and got the required voltage and the controller now works. Thank you.
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on February 16, 2023, 01:11:18 PM
The 3 connections are the entire POT, V, X/Y and G. The V is the AN+ (1.8v) for the POT. That jumper in place of C24 was the RSX-axis short to ground.

There are multiple places where that LSC could fail, no one is going to know exactly where the problem is. Could be the new stick button is also bad, or R16, or a broken trace or bad solder joint or via at any one of several places on that entire LSC line or even the MCU that has the issue.

Doesn't work at all? or it acts like it is pressed all the time?

The RSY POT isn't soldered on that board, and I doubt it's related, but floating Analog lines like that can cause all kinds of weird issues. Also, no telling what all else has been done to that board from just that pic.

Can't make out what kind of soldering job is on those leads from that pic, so the issue could be there. Trace could be open from RB to U4p5 or U4 could be bad. If it acts lie it's pressed all the time, then the RB trace is shorted to ground somewhere or U4 is bad.

Welcome.

U1 is needed for powering the controller over the USB, that's pretty much all that it does. It's an MP2161GJ if you want to replace it, and you can find it at DigiKey, Mouser and several other online parts places.

Hi everyone, my old xbox one s controller had severe stick drift on both sticks so I attempted to try and replace them myself with the help of some youtube guides, I was able to replace the right stick and it works perfectly now, but I made a rookie mistake and didn't apply flux and ovoerheated my soldering iron so I damaged all three through holes for the Y potentiometer on the left stick. It was my first time soldering. Everything about the controller works but I desoldered the Y potentiometer since it sticks to 100% upwards when I apply a conductive adhesive and forcefully solder all 3 holes. Is there anything I can do about it? I came across this website while looking for a solution and i think I'm learning a lot just reading through posts. It is the same module shown in the pictures (1708). I know for a noob who knows nothing it will be a pain teaching but any help would be much appreciated. :beg:

Stop using that kind of wire for starters. Get yourself some 30awg Kynar wire or Wrapping wire.

That TP67 is right in the middle of the trace run, so you've just opened it up is all. You'll need to solder a jumper wire from the bottom of C36/R39 to the Via that is just below the T in TP67.

This world has always caught my attention and for that there is a lot of interesting information in this forum. I'll get the cable you recommended before continuing to liquidate pads 😅.

Should work I've done it on a few controllers because I used too much heat on the TP oh well we live and we learn.

The problem is that the controller does not turn on with the guide button from batteries, but turns on from the wire and continues to work without it on batteries. Also, after turning on the guide, the button is fully functional.

As far as I understand...

The IO Expander on first party xbox controllers is infamously sampled at just 124hz.
The controller will respond when polled up to 1000hz but it will send a stale input state until the IO Expander is sampled again.

What is setting the sample rate to 124hz?
What's the likelihood that this is set in firmware and not a hardware limitation?

Also, I believe the analog sticks are also sampled at 124hz, but they're not routed through the IO Expander; right?

As far as the 'whistling' goes, look around the DC-DC converter that does the USB 5v to 3v, U1. Could be that Inductor is going bad, it has some other iffy part or it's getting loaded down wrong.

No AN+ to LSY = full Up movement.
No GND to LSY = full Down movement.
No AN+ to LSX = full Left movement.
No GND to LSX = full Right movement.

Make sure both POTs have the AN+ (1.8v) and ground they need. AN+ is on TP103 there. Also make sure none of your jumper wires are touching each other or any other solder joints in there.

@Darkelf - Welcome

@WNKLER  - Schematic is on the first page.

It's all firmware controlled. The IO expander clock also isn't used at it's max frequency of 400kHz, it's around 356kHz or so.

You don't want to get into polling things too fast, depending on the kind of switch you're using, as you'll just wind up reading all of the switch bounces as well. At 124Hz, it's not missing any button pressing that a human is doing.

? At 124Hz, it's not missing any button pressing that a human is doing. ?
The motivation for higher sample rates is about the 'freshness' of the input states rather than 'missed' inputs.
It?s not uncommon for modern competitive/esports titles to be run in excess of 240fps.
In this case, there can be multiple frames of frame-disadvantage for a player whose inputs are sampled at only 124hz vs a player sampled at 1000hz.

No idea what will fix it, I haven't seen the board. If the trace from Y to U4 is broken, then find the break and repair it. If the trace from Y to U4 is good, then U4 is probably bad.

What are D14 and and CR1 on  BUTTON/POWER BOARD BOTTOM i have blown them away with hot air?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on December 09, 2023, 10:54:34 AM
D14 is just a Diode for reverse voltage protection, could use just about any diode there. Then CR1 is a Zener, haven't tested the actual voltage, but it's probably a 5.1v to 6.8v max. The controller will work fine with them both missing, they are just protection for 'in case stuff' happens, but you'd have to have a pretty messed up USB cable, console, PC or be plugging it into things that you shouldn't be for them to do anything.

Hello my 1708 is not working over  usb it worked when i soldered usb wires to test points but wire fell of with pads so these compomnents are mising CR1 D14 R1 C3 missing test points TP5,TP1,TP2 i so after that soldered usb wire to Battery terminals and data+ and data- to j5 connector pins it powers and works over bluetooth but is not showing through usb connection

It's not working becasue you have the USB 5v going to the AA rail, so it has no idea the USB 5v is there.

Replace R1 and it should work, unless you've wrecked that USB connector, in which case I'd say just get another top board from eBay or somewhere and use the old one for practice.

If you use a PnC battery pack, that TP5 spot on the bottom board will need to be repaired so the USB 5v can get to that connector.

I got two more questions:
1.What is the size package for R1?
2.If replace it with bigger value like 0.22Rwill it work?
Title: Re: XB1 Controller PCB Scans, Traces and Info - 1708 "Slim"
Post by: RDC on December 17, 2023, 09:59:19 AM
It's 0603 (1608 Metric) size.

0.22R isn't written correctly as the R is used sometimes instead of the decimal, so that means 0.22. which isn't a value. You just want to use the decimal or the R, so 0.22 or R22 mean the same thing, and yes that value would be fine. You could really put anything 1ohm or less there and it would still work. Can even jumper it straight thru for a test if you like before getting any parts.

Hi! Can someone lead me in my little problem?
I have an Xbox one controller 1708 and it has some kind of problems with range of radio connection
It works perfectly through Bluetooth, but if I connect it to Xbox it works only near console. I thought that antenna was disconnected, but it?s not. I?m bad at diagnosing by myself, but can do it with instruction or lead

The bottom 3 are ground, top one you can jumper wire over to the bottom side of D3/C29.

Hey RDC hope all is well!

I have a 1708 MCU board (looks brand new..) where the joystick push button mechanisms work but the XY directional inputs on both do not register anything, nor do the triggers. The "B" button works. Any idea what could be the issue?

Post by: RDC on March 06, 2024, 06:48:12 PM
Those things don't really have anything in common, except the MCU reading them as analog inputs. If nothing on the entire board looks suspect, then try a firmware update.
