HELP! PCB button RB,B,BACK no response!

Sorry if someone have ask the same problem before,because I can’t find any thread about the same question yet.

I’ve mod many pads since now,but three of the pad have the same problem.

The RB,BACK,B is not working at all, all pcb is tested working before I disassemble it. And the PCB is old version, I’ve solder two resistors on the RT,RB points.

So any one have the same problem before,if so please advise how to fix it.

niking, what version of the microsoft gamepad is it?

I guess it’s the old version without common ground.

anyone can help me about this? I’m send the PCB to you if you’re willing to help me about this. :smiley:
