So after getting my PSP (PSP 1000, 5.00 m33-6) out of the pawn shop I noticed something. I have to press very hard on the buttons in order for the PSP to recognize that I pressed a button. I've opened the PSP up several times since I got it back to sort out several things and try to fix the problem with the buttons, but I've not found a fix yet. There appears to be nothing wrong with it. Anyone know what might fix this?
