Question about Hitachi Televison & Video
Most of the times this type of damage is due to panel overheating. This can occur due to many situations but most offten is due to internal mulfunction of some of the high power/voltage driving circuits. You can only hope that the dealer will replace the set under warranty. Do not settle with a repair.

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.
