Top half of screen takes
Plasma screens have a video board that controls the bottom half of the panel, and another that controls the top half. It sounds like the board for the top half is failing. That would definitely make it a service issue, which would be taken care of under warranty, if you are lucky enough to have one. If your warranty is long gone, your options would be to pay for service at an authorized repair shop, or if you are extremely handy, obtain a service manual and see if it is possible to acquire the parts you would need for replacement.
I hope that helps.
Red line on screen
The vertical line, in my case, was due to a bad contact on the flexible printed circuit. I fixed the problem by using a piece of a rubber eraser to apply downward pressure on the flexible circuit as shown in the picture. To locate the faulty section lightly push on the flexible circuit from lef to right untill the line dissapears.
