    Hi there,
    I am plagued by an audio hum from the TV to the Surround receiver and it's only from the TV. I have investigated the ground loop idea and ensured all units were on the same pathway but the hum still prevails.
    I repeat, this is only from TV programs: not dvds, vhs, am/fm stations at all. Only the TV programs.

    Any ideas?
    I have been trying to eliminate this bothersome noise but cannot get around it. Any help would be appreciated.
    Thanks.

    If you're using a CATV box, try disconnecting it and see if the hum goes away.

    Do you have any other electronics other than your Home Theater gear in the same room (ie: small apliances, cordless phones, halogen lamps)? Sometimes these cause interfence.

    Directly from the TV? Using the left and right audio out? If so probably the TV. What kind of TV?

    I have a similar prob with a high-pitched whistle, which comes through reciever - it happens only when viewing TV via my digital decoder but is not present when using the dvd (or the TV without the receiver on).

    I have significant digital reception issues and I suspect this may be the cause of my whistle, kind of like when you get a bacground noise on a weak radio station- maybe it's worth checking out your antenna's signal strength and reception quality? Just a thought.
