Ever since I replaced the housing on my PSP the analog stick has been drifting. Cleaning the contacts had no affect. I know the problem is that there is not enough pressure to make the proper connection between the analog stick and the motherboard but I am not sure of a way to fix it. I cannot tighten the screws holding the faceplate on anymore but if i put pressure near the analog stick it stops drifting. Does anyone have any ideas?
