The matrix controler or the matrix drive area is failing. The fix is to change the proper circuit boards, and then do the factory setup to match the board is necessary. In the worse case, it may be the display screen itself that has a failure occuring.
You will have to bring the set for factory service to have the work done. If the set is out of warranty, it may be expensive to service.

I had the same problem to and I fixed it.
At the bottom of the plasma there are six or seven ribbon cabbles that come out of the panel and connect to like driver boards. Each ribbon drives that section of the panel. Mine had it down the centre so I unplugged that ribbon cable and on the underside of a metal plate attached to it there are four big resistors and four small ones. The big ones labelled 100 required resoldering. Once they were resoldered it worked just fine.

The tv is shot. This occurs when pixels on the top row of the screen break, which blocks current from moving through the rest of the pixels in that column. But don't worry this problem is common and is covered in your tv's warranty.
