Heat might do it I suppose. I wonder if you could "wake" them back up by
forcing each pixel full on/full off over and over?

I have just pulled a heap of old Apple PowerBooks and

storage, and have discovered that quite a few of the LCDs that were perfect
last time I looked at them (some probably not for seven years ago now) have
deteriorated to the point that they are no longer usable. Problems vary
from big black splotches on mono screens, to colour screens with almost the
entire display from the centre out showing only the backlight.
What are the causes for these kind of problems? Heat? Humidity?
They have been stored for the last six or seven years in a cool dry
environment, but did spend one summer in a storage facility that could have
reached 40 deg c at times.
