It sure sounds like a power supply problem, maybe a high esr capacitor?
But if it were me, I would just replace it with a LED LCD flat screen new TV and let the savings on the electric bill pay for the credit charge. Now days, you can get >36 inch LCD sets for ~~ $100 or so. Maybe even better just after Xmas.

Subject: [TekScopes] Zenith 36" problem!
Hello all,
I am having a problem with my Zenith 36" CRT TV. It goes into shutdown mode. When it is cold I have to start it up over and over before it will stay on. Also as the brightness of the screen varies the size of the horizontal axes varies. When the size becomes very small the tv goes into shutdown. I believe that it is dropping into low voltage shutdown.
Also the top of the screen is rolling over and it started about 2 months ago. At first it was just a variation in the size of the horizontal axes but it has been getting progressively worst. Up to last week it would stay on once it was warmed up but now it is shutting down when the screen has a lot of white space on it.
I know that without a schematic and a list of the voltages that it will be impossible to fix it but what I am asking for is any thoughts or ideas of where to look first. This thing is a monster and I will have to have a friend come over and stay here for a while to help me move it.
Any thoughts and/or ideas?
Thanks,
rich!
