I had to swap the volume and power controls by de and resoldering them onto the appropriate chassis. It "works", but I think there is a problem within the remote chassis, because it exhibited this same behavior before I swapped.

Until I saw the thumbnails attached to this post, I had never in my life seen such a weird CRT display on a color TV--and I worked on old cast-off TVs as a hobby for years when I lived in a house with a basement. I would not have thought it was possible to distort a color bar pattern that way, and I have no idea what was going on in your set to cause it. If you just swapped a couple of wires on the chassis, that should not have caused such a display. I am at a complete loss to explain why you are getting this, although I have never worked on a Zenith roundie color TV, or even Zenith rectangular sets. At this point I don't even want to guess what was causing this bizarre screen display.
