suspect panel logic board . you did not give the model number?

may be worth getting repiared,sounds like decoder video o/p.or line o/p stage.

I believe that this could be a type of "burn in". If you watch anything with a black stripe on the sides or bottom of the screen often, then this could be the problem. My suggestion is to watch things that have no black side bars for a while (>week) and see if this eliminates the problem.
Good Luck!!

We originally had a red stripe roughly 3" wide running vertically on the ride edge area of our Panasonic 52" Viera plasma tv. It has now been joined by a solid black stripe of the same width running from the top to the bottom. Living in Germany and purchased at local PX long enough ago that the warranty is likely expired. Now what?

I think you have a frame fault on the tv. If you are capable check the picture frame board first. If not find a competant technician. Good luck.

Hi
If there is no picture behind the stripe and the edges are well-defined, then one of the display driver ICs has failed. Philips displays can be made by several manufacturers - usually Samsung. The ICs are bonded to the flexible ribbon in most cases, and replacement is an expensive specialist job - and in many cases is simply not possible.
A shadow on the picture is much better - usually due to interference.

The bad news, it sounds like tou have a bad plasma panel.One of the vertical drive arrays are in the process of failing.This part is part of the display panel.
