Thanks, I did that very check yesterday afternoon. It occurred to me that I already had a socket issue on the video IF board, so why not check this one? This socket seems solid, knock on wood.

I will try to follow up on the other suggestions. It would be nice if I could just substitute a 3.58-mc signal, as you could do with a video or horizontal drive signal, but this situation does not seem that simple.
