Sounds fishy to me! Picture tubes aren't common to go these days, &
when they go, they USUALLY get weak, & gassey, or blurry over time.
Now, he MAY have put an actual bad tube in it! Ask around about
his reputation. Also, post the model of T.V. Dani.

Hi, sorry if this is a really dumb question but my knowledge of
electronics is pretty poor and here seemed like a decent place to ask
the question....

My TV started turn itself off after half an hour or so. This time
period slowly came down to 15 mins, 5 mins, ... 1 second, no seconds.
If I leave it plugged in for a week this time period goes up.

The repair shop owner (who lives near me) came and collected it and
when I explaind the problem said it was the probably transistor, like a
capacitor that wasn't hold it's charge, but would charge up over a
period of time. Although my knowledge of electronics is very poor this
seemed pretty plausible.

Next day he phones my wife and says it's actually the "tube" (i guess
he means the cathode ray tube) that's gone and the cost of repair is
£100. He quickly follows this up with the good news that he's got
another TV (same make) which is better that he could sell us for £135.

My wife was a bit suspicious and said she would have to speak to me
first.

So my question is, does this all make sense?
If the tube had gone how come a picture was visible?
Does his offer to sell us another TV hint that he's trying it on?

Any help, advice would be welcome.

Thanks

I aggree that it sounds like he may be trying to rip you off. The crt would
not cause that type of problem, least not that I have seen.
Sounds more to me the voltage regulator may be getting heat stressed and is
simply shutting down. I would tell him you are taking the set to another
shop to get a second oppinion, and have them look it over to see if he did
indeed switch tubes with yours. How long has this guy been in business.
Also if this set is not a big set to start with, you may be better off to
replace it as the shop repair will still cost at least 60 to 80 for
replacement of a regulator per say. Jtt.
