Hi Skipp-
I'll bet 100 bucks your problem is with a certain solder location (or
locations) on your analog board. Over time, due to constant heating and
cooling, the solder can become brittle and eventually crack making for an
unstable connection. This is usually the beginning of a condition that
worsens with time. When this condition sets in, I usually just swap out
the analog/video board for a known good one. If you're handy with a
soldering iron, you can attempt to repair the problem instead, however. I
don't know what the exact solder joints you want to look at are on an SE,
I am more familiar with this problem on a Mac Plus. I'm sure someone else
here on the list can point you in the direction of which solder locations
to look at.
I suppose it could also be caused by a loose grounding wire, too... You
might want to check that out, first.

I realize that this subject undoubtedly has come up before but, since
we are on the topic of fixing SE/30 CRTs I wonder if anyone could give
me some advice on how to fix an issue I have with my SE/30. When I
turn the computer on the screen shakes, not unusably yet annoyingly.
It seems to shake most when the machine is first turned on, but lessens
as the computer warms. It may however return after the computer has
been on for a while. I suspect that I have some problem with my analog
board, perhaps a leaky capacitor or perhaps it is having a problem
getting a steady current from my power supply. Does anyone have a
better explanation perhaps?
