this is my first post I hope I am in the right place.
My front speakers are driven by a denon poa2800 amp the center and rears ar driven by my yamaha 5890 receiver. when I turn the tv on I get a quiet buzz out of my front speakers only. It does not increase or decrease with volume adjustment. When I turn the tv off the buzz stops I think it is from the cooling fan in the tv. I ran an extension cord from the basement to plug the tv into the buzz is still there when I turn the tv on.
(50' away different circuit)
The denon amp pics up the noise the yamaha 5890 does not?????
Is there some gadget I can plug the tv into to stop the buzz from back feeding into the wall outlet?
