controller repair not going well
« on: April 08, 2023, 10:56:08 PM »
in the process of replacing my joysticks on a xbox series controller c26 and c307 broke off and now the triggers are reading as always pressed and the left joystick cant reach 100% on left on up direction. could the broken capacitors be causing this and if so where can I get replacements?

Neither of those caps missing will cause those issues. Post good pics of your board.

Upload the image(s) to any of a dozen sites that are for that, then post the link.

OK, good pics meant in focus pics. I can't make out anything that is screaming there's an issue, even from those, but it's really a PITA to try and diagnose blurs. Give that solder flux a cleaning with some rubbing alcohol and a few Q-tips also.

The Triggers are kind of their own thing, for them to both have an issue I'd suspect a problem around C3, C32, C33, C35, C37, R38, R40, U9, U10, U11, or an issue with the MCU. You can also try seeing if the controller needs a Firmware update. If C307 tore the pad up, then U9 would get no power and there would be Trigger issues, but that' doesn't look like it in that pic.

I couldn't find anything wrong with the things you listed. I did upload a new pic to the folder with a closer and more focused look at the broken c307 if that helps.

Around C307 looks fine. At C26 though that kind of looks shorted, though all that would do is make the LSC button act pressed all the time.

What voltages are on U10 and U11 there?

R37 and R41 are 0 ohms, just jumpers.

Check the voltages at spot to the left of TP84, the one above TP84 and the one above TP98.

You really need a scope to see what is going on there.

That's conflicting info. If you have 1.65v to the left of TP84, but 0v on pin, then either R37 and R41 are open, or you have some damaged traces to both Hall sensors, or both Hall sensors are bad.

Connect the red dots with a jumper wire and see if LT works.

You have a 3.3v issue then. Test the top board alone, plugged in with USB cable, and make sure it outputs 3.3v first.

Pin 4 of U9 is supposed to be 3.3v, the top/left pin in the pic I posted. If U9 was bad pulling the 3.3v line down to 1.6v, then all of the 3.3v in the controller would be 1.6v You could try jumpering the top of C34 to 3.3v and see what happens, but I'd want to know where that 1.6v is coming from.

broken track or rust underneath C34,  now i have 3,26v on u10 and u11 , LT RT are normal.
i removed it, scratched and soldered a bridge c34 to u9, now i need way to solder a c34 again without damaging the bridge.

I tried to post a picture in hopes of helping someone, thank you very much boss!

Welcome.

C34 isn't really necessary, it's just another decoupling cap on the 3.3v rail and there are plenty of those in there.
