I saw enough warning labels to make me take a step back. Everything

Next, I'll take a deep and thorough look at safety precautions for re-
capping it. (ie, discharging everything without electrocuting myself
before I start poking around)

Have a read of this:

Well, my initial reason for taking it apart was to replace those caps.
It's still a possibility if the other things mentioned by Michael
(Mahon) don't work.

Speaking of which, What do those things look like? (Ferrite core,
flyback transformer and yoke) I'm seriously a beginner in all this
stuff. What would I need to tighten and how would I do it? What would
I apply the lacquer to?

Most of my experience is on paper with digital components, rather than
opening old stuff and fixing it.

Rather than go into a long discourse, I recommend that you read up
a bit on CRT monitors--Wikipedia might be a good start, but any TV
repair discussion will cover the ground.

You wouldn't pop the hood of your car and start replacing all the
ignition wires without reading up on it, and I wouldn't recommend
doing it with your monitor, either.

Blind replacement of capacitors (or any other component) is actually
a grave risk to the PC board of the monitor, and it is virtually
certain that 90% of the capacitors are as good as the day they were
made.  It's always "one bad apple" that causes a problem, and the
repairman's job is to find it and replace it.  Shotgun approaches
are often seen as a "quick and dirty" way to fix problems, but they
are never really quick, and they are always dirty.  ;-)

Remember, it may not even *be* a capacitor causing the problem!
