zenith chromacolor ii schematics/ tech/ restoration questions
 

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. :tears:

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.

LFOD !

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 :bash: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.
