Plasma TV Background noise

Try by resetting the picture settings. Brightness, contrast etc. Do a factory reset. Refer its user manual for details.

I will need the model number of your set to assist you with the most probable cause of the problem.

I THINK ITS A DEAD PIXEL , YOU CAN'T DO ANYTHING WITH YOU DISPLAY , CHANGE THE PLASMA DISPLAY COST YOU MORE THAN HALF OF THE TV

Sounds like a software or firmware issue...

It is hard to find a company that will tell you where the parts come from. Most parts you cannot purchase in america.
Here is a website I would suggest that will help you at best!

same problem on mine, its a known fault on panasonics website and requires a software update

Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.

If this is a new set, return it for exchange. This is a warranty repair item.

check your sharpness setting, it should be very low and even in the negatives possibly on a plasma. I was told the sharpness option was for crt tube tv's anyway

If you mean the picture froze or formed fuzzy pixelated picture and crackling, this will be due to a poor aerial signal to the tv, but if you mean the screen rolls with pink/white patchwork type squares and shows the picture in the background, all be it fuzzy, then that's the same fault as I am getting and have had to report the fault to LG as I am on my second TV. If it is the problem mentioned in the first sentence, it is happening to our friends in OS and they have been told by specialist aerial fitters, the signal is too weak for the tv.
