Typically when you have an LCD screen and you only see white the LCD panel has been damaged. I.E. unable to produce the color black that mutes out the white backlight. So the screen looks white. I've bricked my PSPs on purpose for testing etc.... and have never seen a white screen like that, not even from flashing bad rcos or anything. The only time I've seen such a thing was when I cracked the contact area of the LCD panel in my mp3 player disassembling it to clear dust. Good luck....when you get it if you give more description someone can help you out. Take notice of whether or not the MS indicator comes on things like that, does the UMD drive spin up at all during boot etc..... Good luck!
