Powerbook Screen gone crazy.

Question

Powerbook Screen gone crazy.

So my brothers powerbook screen suddenly went crazy.
I just wanted to ask if you have any idea what's going on (before I go to the Apple store).

This is an image of the screen working in target disk mode.

PS: last time I checked it had gone completely blank.

powerbook 12inch, Mac OS X (10.4.11)

Welcome to the Apple discussions.

That looks like a video circuit issue. However, first, does the screen change if you move the cover? If yes, the cable to the screen has a problem. Otherwise, If you have the OS X CDs that came with the system, or one of the TechTool products, you can test it. If you have the OS X CDs, find the one that, in small print, says 'AHT Version x.x' on it. Insert it, and reboot holding the option key down. Choose the Apple hardware test, click the arrow pointing to the right, and follow directions. Does that give you any additional information?

If it is confirmed as a video circuit issue, the solution is to replace the logic board, as the video is integrated on the logic board.

well I tried running the diagnostic.
The problem is that the screen always looks like this and you can barely see anything.
I got the test running but you can't really see the results on this screen.
I guess I will have to take it to the Apple store.
If it's a logic board failure, I doubt it will be worth fixing.
