Can anyone tell me what the specific error is with the following problem?
" i start my powerbook G4 it goes to the apple logo and the spinning circle logo for approx 30 secs to a minute then the screen goes to a gray colour with 7 broken horizontal lines across the screen ." I have tried the command c+V option key and it goes through the load and then alot of white lines appear.

I have tried various resets but to no avail.

If this is a Logic board issue (bad solder?) does anyone no of the usual chip/gpu that affects this issue?

I really appreciate any help on this issue.
