Hum from Plasma TV

Try lifting the ground on 3 prong plugs by using a cheap 3-2 prong gray plug adapter from the hardware store. Try the TV first, then TT related equipment.

I did all the that stuff and more. What I'm thinking is the cables from the TT are picking up interference directly from the screen when the tv is on.

Maybe try some kind of shielded tone arm cable? I would move your TT as far away from the TV to see if anyhting happens. It's free and it might present a clue.

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!

I would have to rewire the whole arm to change the cables.



It is a Samsung tv. And it doesn't hum. The Ty is picking up hum when the tv is turned on.
