On the Plus, there are also a set of variable

the analog board setting various parameters (width, height, etc.) of
the video. Those might also be corroded. Running them back and forth
and then back to the original settings might clear that, or some
contact cleaner (which is probably a better treatment for the
connectors than what I list above) might be a good idea.
I'd tend to avoid tweaking those if at all possible, unless you have a pretty
good indication that it's the problem...
Finally, capacitors on the analog board might be
going bad.
An ESR meter could give you some indications there.
I think that's pretty likely. I had one monitor that I was given a number of
years back, EGA when I'd been running mono before that (g), and it was
_very_ wavy, so changing the cap out between that and a scrapper nearby with
a similar chassis fixed it.
And speaking of older monitors, I mentioned this in here once before, but
this guy is offering me a *pile* of older monitors -- mono, cga, ega, but
nothing newer. I'm holding off on going and getting them because I don't
really have a place to put them at this point in time, no storage available,
and he said in recent correspondence that I'd need a truck or a van to be
able to haul them all away. I've got past correspondence from a few of you
folks, but anybody else who's interested, drop me a line offlist, and
let's talk. I'd sure rather get 'em to somebody who can use them than scrap
them out.
