iBook G4 screen - flashing white, black, red, green, blue

Recommended Posts

Got an iBook G4 here that boots up, but the screen displays nothing, just single colours. It flashes from black screen through red screen, blue, green, etc - like when you run a video test with techtool (or similar). I've tried resetting the PRAM and PMU, but apart from a half-second flash of the login screen it didn't do anything.

 

I've looked on Apple's discussion boards and found posting of the same problem:

has anyone else had this problem?

Sounds like the old iBook logic board problem. I'd give AppleCare a call or take it to a retail store.
