My TV is sometimes spontaneously turning off and having trouble
displaying video at times before banging the enclosure to have it
operational again. I have had the TV for about 13 years. Is it a sign
that this TV wouldn't last much longer (hence prudent to purchase a
new TV)? Thanks in advance.

Sounds like bad solder joints on the main board.

I guess I would have to open the case, discharge the capacitors, and
find out other than getting a new TV?

Keep on banging on the enclosure and you will have no choice but to buy
a new tv.

Depending on your skills and location, there are several options.

1. Open the case, pull the circuit board (discharging the caps is a
good idea), and examine the solder joints carefully with a magnifier
while flexing the circuit board. Starting points would include the
horizontal output transformer, the power supply, and the vertical
output IC (it's mounted on a large heat sink).

2. If you are in the US, a large number of used analog TVs are
available on places like Craigslist at bargain prices

3. Buy a new TV. Significant improvements have been made in the past
13 years.

"Turning off" as in turning the POWER off? If that's the case, check
your power cord, wall jack, on-off switch, power strip, surge
protector, and anything else you have in the power line. Also, check
if Junior is playing with a duplicate remote control.

and having trouble
displaying video at times before banging the enclosure to have it
operational again.

What trouble? Goes to black, goes to white, displays something odd,
horizontal, horizontal tear, vertical roll, herringbone, etc? Try
really hard to be specific.

You might want to bang on specific parts of the TV, to see if you can
isolate the intermittent connection.

1. Bad solder connection, cold solder joint.
2. Fried or filthy connector. Plenty of connectors to choose from.
Also, flakey wire crimps on some types of cable connectors.
3. Broken wire bond inside an IC.
4. Warranty timer circuit has been activated. That's the timer that
starts when you buy the TV, and causes the TV to drive you insane
after a pre-determined interval. 13 years sounds about right. Ask
your local TV service shop to reset the warranty timer for you.

Actually what it is trying to do is to tell the OP that he should not
be wasting his time watching mindless drivel on TV!

The most amusement you can get out of an old TV is a well placed M80,
although there are numerous safety problems with that solution.

This could be anything from cold solder connections to failing
components. In considering the age of the set, it would not be worth
the investment to fix it. Over the last number of years there has been
vast improvements in TV design.
