well, change ur screen their is failure in your screen line & row moudle

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.

Ok did this happen the first time u turn on the TV. ? If so u might have a ribbon cable disconnect from the logic or u might have a defective Plasma panel. If u have a defect like your describing the IC's on the panel short out and no longer work causing that section of the screen not to function. Only fix then is replace panel

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.
