Could be a ground loop between your incoming tv signal and the
electrical system.  This is a common problem when the cable TV line
isn't properly grounded. I used to get a slow scrolling horizontal bar
across my television, and a slight hum.

I tried using a MAGIC box, but it caused about as much noise as it
fixed.  The right solution was to make a better connection between
the cable and the house grounding system.
