That's an interesting theory, but not sure it applies to my situation. My modulator has been working fine for a year. Just within the past three weeks has the scrolling bar symptom started - so I don't think it is a grounding issue.
I will see if replacing the 'lytics fixes it, and if not go from there. Waiting on the caps from Mouser along with a bunch of other parts.
Thanks for all these theories, as it gives me a good road map to follow if the first "fix" accomplishes nothing.
