Herringbone pattern in video.
Which is what I tried to point out yesterday.

All color is essentially being blocked in the tuner/ IF because the response curve is so far off.
Turn up the color, and the patterns show up, turn it down, they vanish, but put in video at test point B, and you see color, meaning that chroma bandpass is OK, and the corruption is in the IF, as been very evident for some time now.
Do review this thread, and how carefully and methodically he has been aligning the CT-100.

There is just no getting around that sometimes it has to be done on these sets.
