Here's a summary: The symptoms my monitor was showing were shutting off after a minute or so of use. The green LED light would turn off. Upon turning the monitor on again, the monitor would promptly turn off again. Waiting a while (around 30 minutes) would bring the monitor out of the "mode", and I would be able to use it for a little while. Note that the monitor DID NOT have to be on all day for this to happen. It often happened the first time I used it. I got several responses from DBG%SLACVM.BITNET, 6500erik%ucsbuxa@hub.ucsb.edu (Erik Adams), waire@seas.gwu.edu (Timothy A. Waire Jr.), rhutchin@Bonnie.ICS.UCI.EDU, ckw@apple.com (Chris Wigginton), Marc T. Kaufman , t-jacobs@ced.utah.edu, hoepfner@heawk1 (Patrick Hoepfner), Dan Filiberti , root@MMUG.EDGAR.MN.ORG (Tony Austinson), Leigh Hume , and fratus@mgaid1.niaid.nih.gov (John Fratus). Several people reported the problem would go away upon wiggling the power cord (or even unplugging and plugging the plug). One suggested the problem was oxidation and poor contact of the plug. I tried this with some immediate improvement, but the problem would always reappear. Two people suggested a heat problem, and one suggested there was an autoshutdown feature in the monitor. I disagree with these ideas, though, because the monitor did not have to be warm to show the problem. The rest suggested the problem was either the power supply or the high voltage capacitor. I had the power supply in my monitor replaced, BUT IT STILL SHOWED THE SAME PROBLEMS. I then had the old power supply reinstalled, and the high voltage capacitor fixed, and the problem seems to have disappeared. Several people reported that they have also heard of others experiencing the same problems... maybe this SHOULD be passed on to Apple.... My monitor was 2.5 years old when this started... my advice to ANYONE owning an Apple 13" RGB that old is to get AppleCare for it (especially if you are educationally affiliated, where it's probably only around $30/year). The MINIMUM repair cost for the cheapest part in the monitor seems to be around $90... Atul Butte Brown University atul@brownvm.brown.edu
