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.

Recapped agile modulator tonight and scrolling bars GONE!!
 Two of the 4 caps had nasty corroded leads when I unsoldered them from the board. But none had actively leaked. That was indeed glue on the board from the last install of these caps. I was able to clean the glue off the board easily as well. Thx to those who chimed in on this issue. Video here: http://youtu.be/wgrp8HOewxs

Fortunately, the symptom is very similar to the same problem with a B/W television. Scrolling black bars up the screen were usually failed electrolytic capacitors in the power supply. Of course, our modulators are not exempt!
Glad you got the problem solved quickly and easily. What type of solvent did you use to remove the glue?

Turns out the glue was SO dried out, it flaked off with my finger nail completely. Did not need to use any solvents.

I've got a strange issue with my Blonder Tongue CAMS-60. It's probably been like this for a while, but it bugs me. It's not "terrible", but if there's something I can do to fix it, all the better
 Is there a place on the board to align the audio signal? It's not the audio adjustments on the front. I get slight whistling "S"s from everyone on TV that sounds out a "sss".
