Hello, all!

My current monitor is an Apple Multiple Scan 17 Display, #M2494. You know,
beige Trinitron behemoth.

It, like my aging Mac, has a few minor problems. The stickers from the
previous owner I'll overlook (hey, when you get it for $5, you get it for
$5!), but it does something quite inexcusable. For the first 15-20 minutes
(sometimes MUCH longer) after I boot the system up, white and pale areas
have a green "shadow" off to the right, and the color is rather off. As it
warms up, it flickers in and out of this state until it finally settles
(likely after a few sharp licks to the side or top) into the beautiful,
crisp, color-corrected delivery we've come to expect from our fancy
monitors.

Changing the resolution doesn't zap it into line. Nor do the reset buttons
on the front have any effect on this condition. I've looked over it's
Apple Service Manual, but there's nothing immediately relevant there.
Someone had a similar problem with a different brand screen, and says
replacement of PQR capacitor on XYZ board fixes it.  Not quite what I was
hoping for!

Earlier today I disassembled the unit to hunt for obvious flaws. Not so
much as a cracked solder pad! I resoldered the ones on the CRT board
anyhow, and it's behaving better now though there are hints that the
problem remains.

Any ideas?

Thanks,
Jesse
