there have been a couple of other threads regarding the issue of the backlights going out on Apple's LCD monitors. The top half of my screen has become dim. however, if i turn my computer on and the apple OS load screen is running.. right when that screen turns on my LCD monitor's top half goes brighter than what it sits at once the computer is booted up. this is about a half second of extra brightness. I see this when I wake the computer from sleep sometimes. whats the deal, any clues?
