Audio 'hum' From Components
My receiver has a significant electronic "hum" when my tv cable box is plugged into Video 1, and when my Blu Ray player is plugged into Video 2. I have tried moving the imputs to different jacks, (DVD, etc.), but there is always this hum. It sounds like the old 60 cycle hum that turntables used to produce sometimes, and gets louder as I turn up the volume to hear the tv.
