Hard to tell, but it looks like the picture is all chrominance and no luminance. Turn the color control off and see if the image disappears. With a scope, this would be very easy to find but I realize that not everyone has one.
Depending on the year, it could be a delay line of sorts or a rudimentary comb filter issue.
Some TVs had a service switch of sorts on the CRT module. It will be a small three position switch if it has one. Some had a similar switch on the chassis somewhere, but those were mostly imports. If you can find one, try all three positions.
