zenith chromacolor ii schematics/ tech/ restoration questions

[bjornklh]

So I am a collector of all things zenith. Grew up with an older zenith set, and like them a lot. Ran into this chromacolor ii set from about 1975 and really like it a lot. I ran it for about two hours, somewhat stupidly. I have heard of caps going bad, but overall have had good luck with 70s zenith stuff working well without restoration.

It had a good picture, and everything worked correctly, but then it just shut off with no warning and wont come back on, no burnt smells or acting weird before it quit.

My question is, what is the likelyhood of it being repairable? I am willing to put some work into this set, and have some electronics background, I have re-capped old radios before. Would anyone be willing to help me with a list of things to check on it? From what I have seen of the chassis, it is pretty simple.

Idealy I would like to get it running again, and replace all questionable capacitors and parts that it would need to run reliably. I think the local tv shop close to me no longer accepts work on older sets.

Should be easy to fix. There is NO reason to recap it. Start with the
" dead set" problem. Its a remote & the tuner has an OFF channel on it.
If its stopped there it wont work. Open the door & manually change channels
to see if it comes on. There are instructions in there also. After that it can
be walked through easily.
It was a great set. When we got the first batch I watched it 5 mn then
stuck it in my car to take it home. Ran for years no problem.

I think i know what you mean about the channel off feature. tried changing channels manually and no luck. It just shut off while I was watching it, didnt change channel or anything. Not sure where to go from here.

I tryed tapping it on the side too, sounds weird but the 81 set i had growing up would be working fine, and would shut off the same way, with a bit of a staticky sound from the screen, but would always come back on if you whacked it on the side it worked that way for years, always wondered what caused it. lol

Another question would be, does anyone know a tv tech around minnesota/ north dakota that still works on these?

See if it tripped the circuit breaker.
