View Full Version : Problem with my powerbook screen/scanlines

Sep 4, 2009, 09:57 PM
Hey guys I have searched some apple discussion threads about this problem but I can't seem to find a solution..
My display monitor on my powerback g4 15" is showing scanlines/horizontal. I don't believe it is the display screen though that is faulty because when I hook it up to a external monitor it shows the same lines.

here is what the problem looks like

Before I sent it in to apple I would like to see if any of you could help me out.!

Most likely GPU. Sorry, man:(.
