It's a Magnavox CRT. I had been watching a DVD for about an hour when I heard a popping sound and the TV shut off. There was a plastic burning smell. The DVD player connected to the same power strip was not affected. Any idea what blew and if it can be repaired? I haven't opened it up yet because it's very heavy and I'll need help moving it.

The only clue as to what may be wrong with your TV comes from your description of a burning plastic smell , I feel that the probable cause would be the flyback or eht transformer , when they arc they give off a plastic burning smell . This is my first choice guess . You would need to have a TV Tech to diagnose it properly !
Ignore all the other idiots who said it may be the Tube because it is not . It will be a run of the mill repair for any half competent Tv Tech .

That would have been a fuse. Unless something exotic happened, I would imagine that the power supply failed.
Usually the damage is invisible, concealed within an integrated circuit or filter capacitor. The technician will pull the case off and check for visible damage (occasionally there is some, which shortens the search considerably) and then check for a short circuit within components that he might suspect. I'd probably check filter capacitors and the switching transistors in the power supply; the latter are a rich source of trouble. After that, I'd probably take a circuit breaker and jump the blown fuse with it to see what else might have failed.
If the TV set is fairly new, or it has an unusually large CRT, then it's probably worth repairing. As it stands, however, TV sets are awfully cheap these days, and many are not worth the trouble to repair. Nobody in the electronics repair business is too thrilled about this.
Oh: the TV set is not particularly dangerous--certainly not deadly--to open. The voltages used in modern (i.e., the last 25 years) are quite low. So if you're interested in having a look yourself, go ahead; you'll probably need a screwdriver of some weird length to reach all the little case screws. Don't lose them.

Magnovox huh? Well not exactly the best brand and most likely an older set. Unless your an electronics technician, I doubt you will be ably to properly troubleshoot and repair it or if it's even worth repairing... It's not gonna be a simple fuse as you would hope. If you heard a pop and smelled something burning, then most likely their will be physical evidence of burned components on the main circuit board. If you are comfortable enough, you can take off the rear cover and blow out the lower circuit board with canned air so you can easily see the components and do a visual inspection for a part(s) that look burned.

Don't open up TV, there are places where electiocity is still stored - touch it incorrectly and it might be major hospital-visit shock!
If you're lucky, you might find a local TV repair guy who can come by to look at it (ironically, if you live in a poorer area), more Tv repair guys - in richer areas - not so much but mostly likely you will have to carry it in. Most likely, it's going to cost you #$100-$200 to get ir reapired if it can be so plan accordingly.

That usually means somewhere in the power supply is defective. If you are electrically challenged, you should really not be touching it any further. Capacitors in TV can hold charge for few minutes and that means HV is still active. You could get shocked by 25K volts.... Which can either give you an awful shock, or in some cases kill you instantly.

It's toast. The only thing it's good for now is playtime. I shot a CRT with a 44 magnum one time, and it made a really cool implosion. I'm sure other methods of puncturing it would be just as effective.. just stand several feet back from it when you do it.
Dangerous.. maybe
Fun.. hell yes.
Besides.. it's either that or throwing it away.

TV's have transformers in them! If you are no a qualified professional, it might not be a good idea.. OLDER TV"S STORE ELECTRICITY IN THE TRANSFORMERS/ CAPACITORS AND CAN HARM YOU IF YOU DO NO DISCHARGE THE ENERGY! Sorry for the CAPS. I just wanted to stress the serious nature of what you are about to do and what could happen. You might have blown an internal fuse. It might be easier (and cheaper) to buy a new TV. Good luck!
