Hello, Looking to get my favorite monitor back up and working away again.
I had been using it non stop for a few years, and just before I had to move,
I went through a period of about a week where after it would be on for maybe
an hour, the blue gun or signal would just drop out. I could immediatly power
it off, turn it back on and the blue signal would be back, but then would cut
out again in a few minutes. If I let it fully cool down, I could maybe get an
hour out of it. Jump ahead a year later after it was in storage. It still has
the problem, although last night I timed how long until it would drop out, and
it lasted about 4.5 hours. Let it sit turned off most of today, and it's
running just fine now for about 3 hours, but I suspect the drop is coming.
I had opened it up about 3 months ago, the main board was dusty, the usual
stuff. Took a can of dustoff and a small vacuum cleaner to it, so at least now
the insides look nice, but are still taking a dive. I don't know the vintage
of the monitor, picked it up surplus from Seagate in about 2002, they must
have had a few years prior (they are very good at getting brand new gear
every year and surplusing everything else out..)
I'm taking a wild stab and thinking it might be some caps that have
aged out. There's a surprising lack of great numbers of components on the
mainboard, so I'm not nervous about just changing them all out. Just wondering
if anyone out there has had the same symptoms, or have seen this in any
service doc's as a known problem.
And last: If anyone has a copy of the service manual/schematic that
they be willing to sell a copy of, I'd be interested.
Please reply to this newsgroup or leave an email address and I will
send a reply.
Thanks!

D.
