Title: Series s Controller 1914 not working
Post by: sergod11 on September 01, 2022, 02:01:12 AM

Hello! I'm new member here and i need your help! My xbox controller stopped turning on. I took it apart and connected it to my computer. During the inspection of the board, it turned out that the U5 element is very hot. Who knows the designation of this element and what it can be changed to?

Unplug the Top and Bottom boards, then connect the USB cable to the Top board and see if U5 gets hot. If it does not get hot then check the voltage at TP35. If it does get hot then suspect some capacitor on the 3.3v rail of the Top board.

U5 is the 3.3v Regulator, it's a TPS613221ADBVR, and if it does not get hot with the Bottom board disconnected and TP35 has 3.3v on it, then it is probably fine and you will need to look for an issue on the 3.3v rail of the Bottom board.

I did this and the u5 element still gets very hot. Can you tell me which capacitors I should check? I don't really understand how the 3.3v bus goes. I don't have a scheme. Voltage on the TP 35 is 0.33V

There is quite a bit on that 3.3v rail just on that board. C22, C23, C24, C26, C28, C33, C41, C45, C323, C326. A few other things on that 3.3v rail are Q11, U4 and an unmarked Resistor.

Could be that U5 is all that's bad also. You could remove U5 and inject 3.3v onto TP35 and see if anything else gets warm.

I checked all the capacitors, they are ok. Q11 like too. U4 I did not understand how to check all its electrical outputs. If I remove U5, where can I get 3.3v?

You need a benchtop power supply to inject 3.3v into the board.

Briefly speaking. After a couple of days, I still found a capacitor that was in short circuit. It was c33. Changed, everything worked. Thanks for all the info!

It tells you that is the 33rd Capacitor that they used when they designed that board.
