Powerbook screen problem

by Phillip Barron

Anyone want to help me diagnose a computer problem?

The screen on my Apple Powerbook (15″, Aluminum) has recently started to flicker or scramble intermittently. Sometimes the flickering is preceded by patterned pixel discoloration — an odd “highlighting” of images with purple or green dots. Sometimes the flickering signals an imminent screen crash (although the computer stays up and running). All I can do when this happens is to put the laptop to sleep and put it aside for a few hours; then it may (or may not) wake up normal.

It looks like this…

I have feelers out in the Apple Support forum for Powerbook displays, but any other thoughts are appreciated.
