Ground Loop Humm/Buzz from Television

Hello:

Any suggestions on the following: I have noticed a humm/buzz in my speakers that I suspect is some kind of ground loop. However, it appears ONLY when the television itself is on and disappears when I turn it off. I tried lifting the ground on the tv (which, by the way, is tied to a properly ground satellite cable/box) but to no avail. I haven't found any precedent in any of the archives so any thoughts out there?

Thanks.
John

Hi ReubenT:

Thanks for the response but if you had read the entirety of my post, you would have noted that it is NOT a cable tv connection. It is a properly ground satellite connection. Indeed, when I had cable many moons ago, I used the mondial unit and it was not helpful. Trust me, I took quite some time to search the various archives and I found nothing similar to my post. Nevertheless, thank you for responding.

I am beginning to wonder whether there is a shielding issue with my tv (it is about 10 years old) and it is throwing off a lot of something . . .

Best.

Thank you everyone for your responses but I actually think I may have a more serious problem. In doing a little experimenting today, I noticed that every time I plugged the power cable from the tv into an outlet, a little spark jumped from the connection. Bad news, me thinks.
