Thanks I'll figure that out later, nothing I did changed anything, actually disconnecting the ground altogether did nothing. Thinking when the guy made his own end connectors, maybe he screwed something up then I will start with all of ExDilbert's suggestions, but it has to be the cable coming in as it only started happening when I got cable tv and no other devices produce the hum.
Something interesting, the receiver still creates the buzz when not plugged in.
