My laptop's screen died after I was caught under heavy rain, carrying it 
in a not-so-waterproof bag...

I never knew exactly what happened, but apparently some water got caught 
in the screen, causing the sort of effect Bill is seeing, I think. At 
first it was working OK but large drops of liquid could be seen, I 
believe they were behind the pixels and just in front of the backlight. 
I thought turning it on would help it dry, and apparently it was an 
error... One day after that the screen would not show anything. Perhaps 
some metallic connector got corroded by the water, I don't know.

The screen can still be turned on (it was a year ago), but now shows 
only squarish clusters of weakly colored pixels. Something hard to 
describe... Anyhow my laptop has became a desktop :-( And traces of the 
water can still be seen.

The interesting thing is that it had one broken pixel that permanently 
appeared red. This is now the only pixel with a definite color ;-)

I don't know exactly how you can solve the problem, but in my experience 
turning it on to make it dry did not help...
