Such a small cap cannot produce such a long smear. C7 couples only high video frequencies to the chroma circuits.
I would nose around the AGC / sync separator / noise inverter, since feedback circuits can do weird things and make it difficult to figure out where in the loop the problem is. Check voltges in that area, and substitute V6 if you have a spare. The fact that the smear disappears when you couple to the 2nd video is a strong indication that the problem is in first video or the above stuff that is fed from the first video.
