I recently replaced my LG plasma with a Panasonic plasma, and while the picture quality is about the same, I am now experiencing some hum in my Bryston amplifier. The hum is only present when the TV is on. It is not a constant hum, but more of a 3-seconds on, 3-seconds off type of hum or buzz.
Do you think this would be an issue with the TV? As I said, I didn't have the problem with my LG plasma and my system was all interconnected the same way. Should I go through the standard checks for finding ground loops? I thought those types of noises were constant -- this is definitely an alternating hum/buzz. It is not coming from the TV itself but from the amp. In fact, I switched out the Bryston for a Meridian amp I have in a secondary system and the hum was even more pronounced (but followed the same on/off pattern).
Thanks
