OK, here is the problem. i got a brnd new psp 1.5 on ebay, and this guy has sold thousands. i got it, and after 2 mins, the screen went black, turned off. so i reflashed it to 3.40OEA thinking it would solve the problem. it worked fine for a while. but now, its even worse. it comes on after 2mins, but as soon as i press andy button, it shuts off the screen. battery is full. all works fine except for the screen. please help asap, ive only had this psp for 5 hours, and its already fucked!
