Question about Televison & Video
My plasma TV is buzzing loudly and the picture quality has deteriorated.
If the adjustments on the power board are correct and if you are not at high altitude, the plasma display panel is defective. If the set is off warranty, it is not cost effective to replace the display panel. If it is off warranty, you should give the manufacturers Customer Relations a call. The phone number is usually right on the back of the tv. The manufacturer of the tv might make a warranty concession if they are concerned about their brand reputation. Some manufacturers find it less expensive to just switch brand names rather than make good on defective products. If all else fails, you might get some money back by selling the circuit boards on eBay.

If you can hear any buzzing from more than
a few feet then the TV is defective and needs to be replaced. Buzzing is a
common defect among plasma TVs regardless of brand. It has nothing to do with
the plasma cells working; usually it's a defective board or a power supply
problem or something like that.
