I have a Panasonic 53" HDTV RPTV. I have my satelitte signal coming in on input one which is s-video, with the sound coming in via RCA cables. then i have a component input for the DVD and RCA inputs for the vcr. (the DVD is a combo with the VCR). Today I had the sat on and switched inputs before turning anything else on. on component 1 I could hear the sat audio, not clearly but it was coming through fairly loud. this happened on all other inputs. Is this normal, or is there a problem with the tv?
