Question about Televison & Video
You have what is termed a vertical collapse, or complete failure of the vertical circuit. It is probably dry solder joints about the vertical output IC. Resolder and replace capacitors that are near the IC heatsink also. They probably caused the failure of the soldering in the first place from overheating. Replace the chip also if you have no success. Check also low value resistors about this stage that supply power to the IC. If this makes no sense to you, contact a repair guy. May cost you $80-150 depending on how many parts need to be replaced.

I think that you may end up better off getting a new set, to be honest. My 48" rear projection JVC TV lost all three of its guns after a few years. Total repair cost was $900 (thankful for warranty now - that was not much below the purchase price of the TV). The unfortunate thing is, labor and parts rates are so high in many ways that it's almost as if the TVs are becoming throwaway items. More than a small problem, and you spend a tremendous amount of money repairing it, when you could likely spend a few bucks more and get a new TV with a new warranty. The fact that you were once able to clear the problem by unplugging it, and now you can't, shows that the issue is getting more serious and parts are going to die before too much longer.
I'd call around town, find a repair shop that deals with TVs, and ask them at least for an estimate on the cost and timeframe of repair. I have a feeling that a couple of opinions from shops will show you very clearly that you may want to seriously consider upgrading or replacing your existing TV with a new one.
