SOURCE: Plasma TV buzzing

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.

MY TV JUST WENT OUT W/O NOTICE AND I HEAR A HUMMING SOUND


Sound's like your tv just died on you. It will probably cost more to fix it then to replace it.
Buzzing is a common defect among plasma TVs regardless of brand. The buzzing you are hearing is probably a sign of a defective board or power supply or something similar. Either way, you'll need to fix it or get a new television set.
I know plasma television's are cheaper for larger sized sets but I never recommend plasma's to any of my customer's unless they are buying it for a large sized darker room (such as an in-house theater)
If you want a good, bright, clear picture I would stick with an LCD. If you want a higher end you could go with an LED. They both offer less glare than the plasma plus they are better to use with HD devices such as blu-rays & viideo game systems.
