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

If you are connected to a coax cable TV feed, it is likely that the cable is causing the issue. This is VERY common and has been widely acknowledged on this and other forums. You can purchase an in line isolation unit that will solve this issue. I know there is one made by Mondial and I have read that Radio Shack sells a similar unit. I think the Mondial sells for about $99 new. Here's a link to an A-goN ad for a used one. BTW, I'm not associated with the seller.

I hope this helps.
