My tv keeps blowing fuses.

My tv (phillips crt widescreen) keeps blowing fuses. There must be some reason it keeps doing this, but I can't figure out why. I got it for free from a moving job because it didn't work (blown fuse), and then it worked for about 8 months just fine. Next fuse worked for about two months. And now it works for about five minutes before shutting off. But if I unplug it for a little while and wait, the tv will turn back on and have a picture for about five minutes. Any ideas?

Well, it's obviously knackered in some way - take it apart and look for components that look "buggered" then consider replacing them with a soldering-iron.

 ha, well of course i took it apart. i didn't see anything buggered or knackered or wompered or otherwise....jiggered. 
But i will certainly take another closer look. 
Another detail i forgot to mention: just moved to a newer house (old home was built in the 20s, new one built in the 70s.) Would newer home wiring have anything to do with it? 

It could make a difference depending on the type of circuit protection you have now compared to your old house.

 ah. an even easier solution: i was plugging the tv into a really crappy powerstrip that couldn't handle my tv's power requirements. i plugged it into a heavy duty one and now its just fine.....
Well, that's interesting, you might maybe have answered your own question.
Your electricity provider will tell you what they're providing and that it's under control, but they might be "spiking" you.
Consider a "surge protector", whilst thinking "at least it's just a fuse (again)"

Or perhaps replace the "knackered" or "buggered" component with an equivalent if not identical new component rather than a soldering iron. ;D

Failing after it warms up: Sounds like a classic problem of one of the components having become temperature-sensitive. We used to diagnose these with a spraycan of "circuit cooler", which allowed chilling one part at a time until we found the one where cooling it down made the device work again. Then there's the question of whether the device is something simple and available... or a bespoke part that you can't obtain, or can't obtain in less than repair-shop quantities.

Of course this is assuming circuit cooler can still be obtained. The old version was basically freon, and went away when that became illegal. I'm not sure whether it has been recreated with a new refrigerant.
