My mono display has been exhibiting weirdness lately - any ideas would be
welcome:

The display starts flickering where vertical lines will be drawn approximately
every eight characters, heavier at the top of the screen, lighter towards the
bottom. It seems to be worst when I first turn on the monitor, although today
it hasn't gone away. Fainter vertical lines are drawn between the heavier ones,
and at times all the white areas of the display will become black, but there is
a fuzzy white shadow near where the text would be.

My assumption is that this is a monitor problem, not an ST problem, for two
reasons. First, using the ST with a color monitor works fine. Second, bouncing
around the ST has no effect. Also, since the lines are fainter towards the
bottom this seems like an analog problem, not a video memory problem.

Do these symptoms sound familiar to anyone? Any suggestions what to replace in
the monitor, or should I take it in, or just scrap it?
