My triangle button works sometimes in games but dosent others and is really buggy, I do have a led kit in the Co trollers so that could be making it bug out too? Please help
i see you mentioned the LED kit in it. i kinda doubt that the LEDs would mess with only one button. i would say open the controller back up again and check the rubber contact pad for the triangle button. see if maybe it got folded over or something and its not making contact properly. if thats good try to clean it with some alcohol on a q tip. also try rubbing the alcohol on the copper contact on the board and make sure theres no other corrosion on the PCB.
