Has any Mac][ owners noticed their AppleColor (sic) monitor
having a tendency to "Shimmer" when first turned on ?
The monitor will shimmer for a couple of minutes then stop
and behave it self until it is turned off then on again.
The technician at our dealers has had the monitor in for
service twice. Both times he claims he has fixed it!
Thanks in advance,

If it is annoying to you during intermitant shutdowns and powerups, you might like to power the monitor separately from the base unit. | Thanks in advance, Hope this has helped mate. Stu.

Regarding people having problems with the Mac II colour monitor shimmering for a few minutes after being turned on, we have a similar problem in our facilities. According to Apple and Sony, the manufacturer of the monitor, the equipment is rated to require about a half hour warm-up time before it is necessarily going to perform up to its specifications. This means even if your shimmer lasts for TWENTY MINUTES, there's nothing wrong with the monitor, and it probably can't really be 'fixed.' Yes, that's a pain because when you turn your computer on is when you want to use it, not a half hour BEFORE you want to use it, normally. Stu's suggestion that the monitor be powered separately from the computer, i.e. plugged into its own receptacle rather than into the back of the Mac, is valid. It would be a good idea to turn the poor thing off when you go home for the night, though. You could turn it on in the morning as soon as you come in, and by the time you've finished playing 'telephone tag' with all the people who've left phone messages, and read your paper mail, your monitor will be ready for you! -- Mark H.

That shimmer is characteristic of older logic boards in the AppleColor. Your dealer should have received instructions from Apple on dealing with the problem. It involves either replacing the board or making some internal adjustment. My dealer fixed the problem (which never occurred until the newer logic board was replaced, evidently with an old one, after other problems). It was quite irritating but I didn't take in for servicing until I ran across a news item in MacWorld detailing the problem. That issue would have been between June and August of this year, I think. Perhaps your service tech doesn't know quite what he's doing... -- -- Stephen D.
