Zenith 5311U / 24MC32 restoration

[Tubejunke]

The metal control panel door definitely isn't as tough as they made the chassis and such. I wish I knew where to get a better one. Those screen shots look good. Did you have to do dynamic convergence work? Hope I didn't miss the answer to that in this thread. Just curious as mine needs it. I can live without it, but the Zenith's make such a nice picture, it a shame to go without.

Got a test pattern gen, hex diddle stick, and a chassis #? You'll need a gen with cross hatch to do it, and a diddle stick. I've got some Zenith issued color service manuals....It would be a trivial matter for me to post pics of the convergence procedure documentation for your chassis (or the closest one I have lit for).

Most deltagun sets have the same convergence procedure and some makes/models were kind enough to essentially number controls to walk you through the procedure.

I do in fact have an old RCA dot bar generator and a diddle stick. I would need to check the stability of the generator as I seem to remember it being a bit persnickety last I used it. Someone rigged the end of the input with a bunch of resistors in a haphazard way for some reason. Anyway, yes I would like to do that. I think I have the Sam's folder in .pdf for the set. Sorry, it's just been sitting for a few years waiting for the "significant" to vacate.

"Another problem is you may see some slight bars in the picture on a black screen. I was not able to track down that problem. Not that noticeable, And most people would not even see them."

I've always noticed them too, quite common on roundie Zeniths. About three light/transparent vertical bars, no foldover, just there!

Interesting you mention that. Mine has them too. They are not a problem, but just there.

There is no way i would use those surface mount caps unless you want to see a failure in a day or so. throw them in the garbage.

I haven't done anything yet except replace three tubes. Guess I got lucky New caps should arrive today.
