Red and green lines on my screen

Hello,

For the last two months, small red and green vertical lines (which look like small clumps of barcode) have been appearing all over the screen of my iBook G4. They're not always there, but they come and go as they please, regardless of what program I'm using.

The lines don't appear in screenshots, but they do appear on other computers if I'm desktop sharing on iChat. I haven't tried reformatting, but I only want to do it with some assurance that it will be worth the effort. Does anyone know a fix?

Regards,
Olls

iBook G4, Mac OS X (10.5)

Hi Olls,

That does seem weird. Do you have a mini to VGA adapter? That would verify that the output of the graphics chip is bad.

Yes probably not until you test it with the adapter and an external monitor.
