I the picture there is a black line between Brian and Stewie that runs top to bottom
half way down you can see it bends. It starts from the top to the bottom.[/QUOTE]
The line in the picture you are referring to is supposed to be there, but the bend isn't. There is probably 60-Hz hum getting into the deflection circuits at some point. I am at a loss to explain just where the hum is getting into the sweep circuits, as you said you replaced the filter caps. Elsewhere in this thread (I think directly above this post), DaveWM mentions other caps that could be defective and causing the problem as well. I would replace every filter capacitor in the set, since in a TV set of this vintage they are probably all either already defective or are getting there, slowly but surely. The CTC16 series is from the mid-'60s, so it is almost a certainty that every filter needs to be replaced; since those caps are now at least 47 (!) years old, a complete recap is in order.
