Hi
so the panasonic people took a look at the tv.. tinkered with the innards and tightened the screws on the circuit boards and now there is no buzzing sound. But they said its better to replace the board as it might fail later on.
Sadly, due to the discontinuation of the plasma line, they dont have any spares available to replace. Since the product is within warranty they offered to give me another tv ( LED ) instead. Panasonic AS670D..
any thoughts on what direction to take ?:sad:
