Well, I finally had a reason to hook up my cable - I wanted to watch the NCAA tournament. To my surprise, as soon as I screwed the coax cable onto my VCR, I started getting a constant hum in all of my speakers and subwoofer - and my VCR wasn't even turned on yet! The hum occured when ANYTHING from the VCR was connected to the amp (audio or video). How do I get rid of the hum? Is the coax in the wall too close to a power run...or is the problem elsewhere? Thanks in advance! P.S. Receiver is a Denon 3802 if that helps.
