Hey folks, I'm having a problem with my sub humming quite loudly when I have my TV connected to the reciever.

The connection path is as follows:

Coax RCA from sub to reciever.
S-video from reciever to TV.
Cable Coax from TV to wall.

I've tried a nicely shielded cable for the connection to the sub with no improvement.

I can eliminate this Humm by disconnecting the S-Video cable from the TV to the reciever or by disconnecting the Coax cable from the outlet to the TV. So I'm pretty sure its coming to the reciever via the cable outlet.

I know all the cables are shielded other than perhaps the S-video cable.

It's not to big a problem as I don't have the sub on when I watch TV and I can disconnect the TV when watching a DVD or listening to a CD but for convience sake I would rather not have to go through this everytime I use the sub.

I'm really not sure what to do now...

Any help would be very much appreciated.

Cheers, Jag
