Screen-shots to defective LCD TV panel is given. You can compare it to that of your TV's, and can make sure.

Panasonic does offer a one-year warranty. You might want to check the details of the warranty to see what is applicable to your situation. Your best bet would be to take it to an authorized Panasonic repair shop; find out how much the repair would cost, and weigh that against the cost of a new(er) TV.

Good Luck!

I think u Panasonic viera creating these problems due to magnetic field around d area,so suggestion is that keep away magnetic devices like ur speakers etc & may be ur TV pitcure tube was damage so u have to go for a repair man....thnx for giving me ur important time..:(

pls contact ur near Service center..because only panel replacement can made your tv ok.

I think they not. They will only repair your tv.

I would diffidently take it to a repair shop and see.If it's a projection screen then that's what it is,a broken mirror.

This not repairable,it a LCD screen have minor pixels cracks in the LCD screen itself,some body hit the LCD Screen with somethings.

The display screen is the most expensive part to replace in your plasma tv. In most cases its cheaper to buy the same model. Instead of buying the part and paying a repair man to fix it....Broken screen = junked plasma

The main driver board, or the main processor board most likely has a failure. The authorized Panasonic service rep can replace the defective boards and perform the necessary adjustments to match them up.

If the set is out of warranty it may be expensive to service. Using the set with a defect can cause more damage, and thus may increase the cost of the final repair.
