Since the smear starts on black lettering, it's possible the AGC circuit is conducting during trace when it should be gated off. It would be good to know that the 450 volt keying pulse on pin 9 of V6 is there, as well as whether V6 is good.

Also, in case the smear really is still there when you inject into the second video, check any caps in the following video circuits that are .01 uf or larger.
