Last time I picked up a radio station through speakers was on my electronic organ in my home. The only solution lifting the ground on the power plug. I thought I was getting the same thing through my surround sound until I started hearing South Park. It turns out it is TV2 on my 622 somehow getting into TV1's audio lines. My stereo receiver doesn't have optical out (too old) so I am using the RCA jacks. I've disconnected/reconnected cables. Tried different cables, grounded, ungrounded and so far no solution. It seems to be internal within the box. Is this some sort of ground loop going on?
