Panasonic TH 50PX60U sound

Have TV sound turned off via TV controls.

Connected audio from Cable box to home theater sound system.

TV puts out a sort of feedback sound at bottom right of TV when facing screen, and it sounds like a fan or actual feedback.

Electrical plug is in correctly as it has a grounding and therefore polarity is correct.

How can this feedback-like sound be quieted?

Thanks in advance

Plasma sets do have a fan!
If you don't face the screen you still have sound?
Feedback is very loud screeching sound!!!! John

Sound is probably from fans then. Audio comes from home theater device, sounds good in digital surround.

Facing screen on right, lower right, is sound I am writing of, a humming sound.

Monster HDMI video cable (ultra 800) from cable box to TV is only cable going to TV.
