One other idea occurs to me. If your TV has a 3 prong plug try a cheater that eliminates the ground and see if that solves the problem. Also you may check where the cable enters the building and see if they(cable company) used a grounding block and check that connection. Just another idea.
Serious hum problem. Help
Long time no post...
I just moved, and hooked up my system to my housemate's television. The TV gets its cable signal directly from outside- ie through an RF cable, no cable box. Whenever I plug the RF cable into the TV, the hum is awful. Changing the input on the amp or switching cables out makes no difference. I bought a new, shielding RF cable, but it didn't help at all.
Any ideas?
Thanks!
