Hum from Plasma TV

Is it a Panasonic? I had the same problem with mine while it was on warranty. Panasonic sent a tech to my house, he opened the back changed out most of the screws holding the PCBs to the housing. It mostly solved the problem, there is still some audible hum but it is really faint.

The issue was a loose transformer on one of the PCBs. They change all the screws just to be sure that it won't occur again on another board.

You can tell if this is your problem, if the hum becomes louder when the screen is white. My hum was coming from the top left corner.

Good luck, it is really frustrating!

Evank, sorry should have read the op more carefully.

Based on your system pics could it be caused by your centre sound bar speaker located below your TV?

Note that my TV is located as close if not closer to my tonearm than yours and I have no hum issues. Mind you my arm is shielded.

On the basis that the source may not be the TV, try running the TV without the cable or satellite decoder or any other device used in conjunction with the TV.

Hope this helps
