Default Bad connection on tv

Panasonic 17" color tv, mnfgr'd 1987. Standard design, layout near as
I can tell.

Dog bumps tv stand, pic is still viewable, but goes snowy and has
pulsing waves across screen.

If I fiddle the power cord where it enters the box or bang on side of
box I can get the proper pic back, if only for a second or 2.

I'm not particularly skilled at electronics, but if I could get proper
access to where the cord connects to the power supply, I could likely
solder the connection or some-such. Access looks kinda problematical:
it's right under the nasty ol' CRT. The one that stores (what?) 20k
volts?

More than likely there is a broken /intermittant connection, or the
circuit board itself, or some other component(s) have been damaged.

Considering the age of the set, I would not want to put any serious
money in to this servicing this set.

I know, I know. The unit is truly jurassic, and the new LCD's etc
are priced down a bunch. But it's stereo and it's connected to my
jurassic stereo audio system. And I don't think enough of what they
broadcast to spend any $ on it unless I have no choice.

Any ideas on how to approach it? Just workbench it and start
disassembling stuff? Cautions other than about the 20kv "gun" at the
back of the CRT? Etc, etc.
