Very old GE TV dies- what could be wrong?

I've enjoyed for 8 years a nice, jumbo sized, handsome real wood box,
cubic shaped, on-a-lazy-susan-base, GE TV, model 25PP5859K (built in Nov.
1984). I bought it used in 2000. I don't have or want cable TV-- I only
watch free, broadcast type TV shows. [I've had this TV connected for maybe
the past 1.5 months to a cheap Magnavox TV converter box.]

The other day I turned on the TV, it worked fine for a few minutes and
then suddenly goes dead. This pattern can be repeated after a short rest
of the TV: it goes on, picture looks fine and sound is OK and then suddenly
dies -- goes totally silent and black -- after a few minutes running.

What could be wrong with it? Does this sound like it's the main picture
tube which is shot or something else? [This TV must have been a
costly, state-of-the-art one when it came out in 1984, so I guess the best
electronics for its time were used in its construction.]

Tell me what you think or suspect.


Thanks
