Apple Powerbook damaged screen - fault diagnosis
HI
I have an Apple Powerbook G4 which has been dropped. The screen is physically intact, although one hinge is broken so the screen is attached to the main case at one end only. When it powers up, the display is 'scrambled' flickering horizontal lineswherever there is an image. I've hooked it up to an external display which displays fine. I've opened up the main case and screen casing & 'jiggled' cables, disconnected cables, etc, but no change to the display. Do you think it possible to determine which component is the source of the image problems. As I say the LCD unit itself looks intact.

Could be the edge connectors to the screen proper that have become unseated. This may prove a bit tricky to fix; a replacement screen may be a better way to go.

Thank You Arthur and RID. The owner has decied to bail out on a fix - I'm to remove the screen & then he'll use it like a desktop with an external monitor. Thanks both for your information - I have a better insight as to the various components that make up the video system and that link to the disassembly instructions was really useful Arthur.
Thanks

The video cables run thorough the hinges, most probably they're damaged. You can also try opening the screen with the 4 screws around the side edges and pull the screen apart, as it is glued together.
Have a look on ebay for cheap spare parts.
Hope this helps,
Cheers,
Arthur
