We have a very old TV set, bought back in the late 80's that has no remote, no cable-ready anything, and that you have to manually turn on with the volume control knob. It's so old that it still has the old VHF and UHF dials even. But for nearly 20 years this TV has seen limited use but given us still a great picture despite its age.
Now all of a sudden the TV set is turning itself off and then on again right after we start it up. This usually goes away after 10-15 minutes, but it is quite annoying. And when you first turn it on, sometimes it will start then go back off immediately and takes several minutes of turning it back on each time it turns itself off before it stops this.
Seeing as how old this TV set is, is it really worth taking to an electronics repair place? What could be the cause of it? The tube itself is still very clear, none of the colours in it are bad or off at all! So to me it sounds like a short in the on/off switch - but I wanted to get some opinions before investing in a new one. After all, it's rare to find any piece of electronic equipment that lasts almost 20 years so I feel like tossing it aside just because of what may be a simple problem! I know new TVs are cheap, but I'd rather spend the $100 to $150 on other things more important if this can be fixed for a modest price.
Thanks in advance!
