What all do you have connected to the TV? Are you using a Pre-pro that you can connect everything to then just run HDMI from the Pre-Pro to the TV? If you are running analog IC's to the TV and they are picking up interference from the AC cable then maybe a shielded power cable would help. If possible try to have your analog IC's cross the AC cord at a 90 degree intersection, if they must cross. If they are coming out of the TV mount area and must be together, try sheilding them as much as you can.
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?
