Amazingly, the control door isn't broken, and all the buttons all work. It's the first time I've seen a Zenith that had working buttons on the door! It does have a very good picture for being 34 years old. The auto CRT bias really works to keep proper gray scale from the moment the CRT warms up.

All it needed was the 10uF 315v cap that often fails. Strangely, the left side was only slightly darker than the right, and the gray scale didn't look that bad, but it really messed up the color decoding. Flesh tones were either green or blue. In the middle, everyone just looked pale even though other colors were strong.

It's just a slight buzz on bright highlights. I can remember adjusting the detector coil on similar sets, I just don't want to go in randomly tweaking things! Either that, or the AGC should fix the buzz.

I used to have a stereo model with the controls on top and a speaker on each side of the screen. I pulled it out of the trash and used it. It always had a bad power control circuit...Only way to power it up was to slap it on the top. Last move about 10 years ago I returned it to the place I found it because I had too much stuff...
