Hi, I've done a few different google searches but I can't seem to find any answers, I've got my nephew's PSP 3000 here and it'll play fine for a little while then the screen will go black but the sound will still be playing. I'm guessing there is some problem with the screen but I can't figure out what it is as I've taken it apart but I can't see anything wrong with it. All I can say it that it's not a CFW problem as it hasn't been modded. Has anyone else had a problem like this? Or know what's wrong? Thank you in advance for any help.
