Troubleshooting the PowerBook G4 15" (FireWire 800): White spots on screen

There have been a number of complaints of white spots on the displays of the new PowerBook G4 15" (FireWire 800). MacFixIt reader Alwi Yunus writes:

"I?ve had the problem occur on my PowerBook purchased the day after the release at the retail AppleStore in Newark NJ. I had the screen replaced back home in Malaysia but five days after the screen replacement, the spots are back in the exact same configuration and place. I?m convinced that the problem does not arise from the screen itself but from the bottom half of the clamshell ? from heat generated by the bottom half of the powerbook damaging the display when the powerbook is closed.

"That is the only explanation I can think of for the problem recurring in the exact location of the original spots. I?ve put up pictures of my PowerBook at http://homepage.mac.com/alwi/PhotoAlbum10.html"
