High Pich sound comming from Receiver and Spaeakers, what is this?

[Pat D]

Its more like this,


I tried turning off my TV and I can hear a slight buzz, very faint just coming from my speakers. But when I turn on the TV I can hear that high pitched sound again. I think its my TV. I guess I am doomed to hear some noise on the line. I just wanted a nice tight sound that doesn't have all that extra buzz to it. Maybe it my cheap o RCA cables from Radio Shack. Would replacing those help any? Any way to block interference from TV?

I take it that you get the audio from the audio output TV as source which seems to have noisy electronics. We use a hi-fi VCR to receive the TV signal first and then it is passed to the TV. But we feed the audio line output of the VCR to the receiver. Our VCR has much quieter electronics. I gather with some AV receivers this can be done with the receiver, but I am not familiar with yours.
