CT-100 color sync issue?

[Phil Nelson]

I'm guessing this CT-100 has a color sync problem, but I'm open to other theories. The color bars are bright and stable when I connect a pattern generator:



When I switch to any other source, we get the same old rolling color bands, which are usually so faint that the picture looks almost monochrome:



Going through the color AFC alignment procedure didn't fix anything. You can see more pictures and read about other things I've tried in the updated article:

Scroll down to the section, "First Picture With New Picture Tube."

I'm just about to take the chassis back out for another round of checks & tweaks. If you think I'm barkin' up the wrong tree, now would be a great time to say so
