i am having problems with my nokia 770 now and this white screen error started this afternoon. I can still see the logo a little but still see the blue lines across the screen. but i can still see the screen, control the buttons a little, and hear the theme nokia logo sound or whatever. but is there a way that i can fix this problem. and one note... can anybody tell me how to flash my nokia maybe that will work.

No, reflashing doesn't fix the white screen, unfortunately you'll need to send it in for service.
