Thank you. I disconnected the cable box, unplug it from the wall, now I connected the cable straight to TV, the hum is still there (the only wire that link to the system is the hdmi cable from Bluray player to TV). It is the cable tv line that cause the hum not cable box. Will the isolator fix this? thanks again
Checked cable junction box outside the house, I opened the box and found that they forgot to hook up the ground wire. I hooked up the wire, no more HUM!!!!! Great advice Bob. Thank you everyone for all your help.
