Title explains everything. My PSP's face button's just died on me. The X O  and /\ buttons don't work, but every other button does. I couldn't test out the analog stick and L and R buttons because I couldn't select anything. I have tried pressing them hard, and shutting it down and switching it on, but they didn't get back to life. My only guess is a glass cleaner named "colin" which I used to clean it's screen about a month ago. If it is due to that, why did the buttons die now?
I have a morbid feeling my PSP's dead.
Can anyone help me?
