Default Problems diagnosing TV

Kind folks,

I'm having a hard time trying to guess what's going wrong with our TV,
though, to be honest, I haven't yet cracked the sucker open because I'm
only home when the baby in the same room is trying to get to sleep. The
TV is a 20-incher less than 15 years old, bought recently used.

Problems:
-- Picture moves vertically, sometimes drifting, sometimes jumping,
generally moving downward

-- Hugging the sides of the TV at the back seem to fix that problem

-- Screen will turn to static and take sound with it; turning it off and
then on again fixes it temporarily. It's almost sudden onset -- maybe a
second or two of fuzziness, then a washout.

-- Warning sign of vertical movement seems to be increasing
fuzziness/static in display, though nothing too seriously. Black is no
longer quite so black.

-- The complete fuzzout seems to be driven by something else, like it
has to be on for an hour and then it's constant.

I thought this was a problem with the vertical hold circuitry, but the
fuzzout with sound is completely throwing me for a loop. That makes me
wonder if there's a heat/dust problem going on.

Any advice would be greatly appreciated. I'm of the mind to try a
vacuum, canned air and some electric parts cleaner, but I'd love some
direction before I electrocute myself. =)
