RFI from steel TV bracket?


Yesterday I installed a new TV on a steel wall-mounted extendable bracket between all my electronic components.
I now have a low hum/buzz from both speakers on all sources....even with the preamp on mute?
When I switch the preamp off.....the hum is still there.
The only way to remove the hum is to switch the amps off?
I tried grounding the steel bracket to the preamp and then the amps without success.
The previous TV was in the same location but sitting on the shelf.....not a steel wall bracket.
Any help would be dearly appreciated?

Halcro, you may want to look at the Mogami 2534 or 2549 cable. It's what allot of studio's use because of their abillity to be quiet. Low capacitance and fairly cheap to what's out there.
