First do an ESR test on all the caps in the monitor, especially in the scans
and power supply. It is very likely you will have to change many of them to
start with.

I just purchased an old Commodore 1902 monitor (analog RGB/digital RGBi
15Khz built in 1985) to replace a similar Commodore 1084D monitor. The
previous owner had it in storage for some time. The monitor will turn itself
off (apears to look just as though I physically turned it off...but power
light above switch will wimper a few times before going out) after about 5
mins from a cold start, and about 3 mins after a warm start. As soon as it
turns itself off, I can turn it off and on again right away and works for
another 3 mins or so.

One thing I noticed about the display (as soon as I turned it on for the
first time upon purchase) was that the sceen was quite intense as though the
contrast was to high (not brightness control). Turning the contrast control
all the way down was almost normal but even still to high....not sure if
they are related....

My electronic abilities/skill only afford the ability to seek out bad
electrolytic caps, measure resitor values and check diodes....before I crack
the case and look for obvious signs I just wondered if someone has
experienced this before (I imagine it is a common problem for monitors of
this age) and could point me in the right direction.

Please respond to the newsgroup and my email. Thanks! jerry
