Brian,

        Yes, that is a cabaret cabinet.

        You have a problem with the deflection circuitry in your
monitor. That's about all I can say, because I've seen the problem
before, and most of the time, it is a problem with the deflection
amps on the deflection board, but once, I found the problem to be a
bad deflection yoke.

        Try to get ahold of a good deflection board somewhere (you
might have to pay a nice chunk of cash for it) and then either:

        1) Swapping in the new, good def. board will completely
fix the problem

        or 2) You'll know it's the deflection yoke that is the
problem.

        If it makes you feel any better, I have 2 or 3 deflection
boards that I need to fix right now with the same symptoms.
