The main difference I see between the last 2 pictures is loss of color sync (barberpoling) in the second picture.
You fix babrberp the way I described earlier by adjusting the chroma osc transformer with a color bars test pattern and color level maxed and fine tuning set for the worst position that gives recognizable color/barberpoling, and adjust color osc to achieve sync under that worst case scenario so that it syncs very easily under better fine-tuning/signal conditions.

All the adjustments I did was in the IF transformers v1 2 and 3 to get to where I am now with the color picture which was a running video and that test pattern so I want to be careful and sure about turning other things turning the IF adjustments was bad enough. The color level on the tv is set really low. I’ll have to check the sams for which trans is. Which coil is it A17 or A18 one says chroma reference osc the other is chroma reference osc control.
