Help! Is My TV Dead?

Question

I have a Samsung TV manufactured in 1998. I picked it up from a trash pile on bulky-item pickup day!! To my surprise, it worked fine. But occasionally, the picture would "compress" or shrink in an oscillating fashion. It would "shrink" in the way that the image "shrinks" when you turn off a TV (right before the screen goes black). It would oscillate, and sometimes turn itself off. (sound was fine) Gradually, this started to happen more often, until it began to turn itself off after only a couple of minutes. Now, when I hit the power button, the TV does not come on at all, but there is a "click" sound, followed immediatley by another "click" sound as the TV shuts itself back off. Any ideas? Thanks!!!

Observe all proper safety precautions, and resolder the connections to the flyback to see if that cures it.  BB

I don't know how to identify the flyback. I have soldered and desoldered things, but I don't know TVs too well. Do you have a link to a diagram/picture, or can you explain how to locate the flyback?

Then you honestly should take it to someone who does, as it's not easy to describe such a part to someone who doesn't know one from Adam other than it's part of the tube on the end concerned with voltages to the gun (often in the thousand of volts). High Voltage components are not to trifle with and a flyback is not a DIY repair for the average Joe. I am being honest when I say that this is something you cannot do with your level of knowledge, while you were looking for a DIY fixit cure anyone could accomplish. This is not that repair. I wish I could paint a rosier picture or rule out other problems or even provide a website. Google flyback or CRT or TV tube construction, or similar and perhaps that will help, or consult a local broadcast engineer or TV serviceman or enthusiast, and that would be better still. until hit back the
