Hopefully you problem is already solved, but just for the record I will post this... (1) Connect controller to computer using USB (2) in Windows, press Win+R and type "joy.cpl" (without quotes) (3) in opened application select your controller and press properties (4) Press buttons on your controller to see if they are triggered correctly (in my case I was able to see that dpad is pressed permanently without me doing anything) Above steps will help you diagnose what's wrong with buttons! (1) Once you know which buttons/dpad/thumbsticks/etc are affected you have to disassemble controller using iFixIt guides. (2) In my case (Xbox One Controller with Bluetooth) I had to reach motherboard with dpad because under dpad was white tape that was not accessible to easily remove... and I needed to do it to clean underneath (and metal "squares"). (this tape is needed, don't mess too much with it) All the best
