Possibly, the interconnects to the amp aren't shielded and picking it up(?) or, if this TV is a Plasma, they do give more interference.
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?
