Yes, experimentation confirmed. I pulled out a long extension cord and plugged the TV into a different circuit. I have been running the TV for a while now, and the audio equipment is happy and not buzzing. The TV still buzzes itself, but much quieter. As mentioned above, this could be a ground loop problem. But only the TV appears to cause it. Could it potentially be the power supply in the TV is flakey or maybe drawing too much current? The outlet that I am using is dedicated to audio/video and is itself properly grounded. In the mean time, I will read up on ground loops and see if anything can be done. It isn't really practical to plug the TV into a different circuit so I would like to find a solution where it can be plugged in with everything else.
