You have a burn in problem from watching widescreen movies.If you have access to a signal generator or tv setup disc run a perfectly white screen on the plasma for about 30 min.This should help even out the pixels on the display.

SOURCE: Top half of screen going black.

I've seen this or something similar to this problem on an old lcd screen. The bulb haden't burned out but the system was no longer getting proper 5 volts to the processor chip that processed the image. I ended up desoldering the voltage regulator and soldering a new regulator in it's place it was one with the same amperage so I put a heatsink on it to reduce the chance of another failure.

SOURCE: Have sound but no picture on Samsung plasma

It's a pretty common problem. The no picture but sound problem is usually the y sustain board. I've replaced 2 on mine now. The 680uf 35V capacitors usually are bulging because one of the power transistors went and took them out. This has happened to both of the y boards I had. One time the failing y board took out the buffer boards too, and once it did not. The fix is super simple and anyone with even the most rudimentary knowledge of computers or electronics can do the labor yourself. You should do the simple stuff first by just doing a quick test with a multimeter. Just check the power coming to the y board. After that you can just remove the y board by removing 3 cables and like 3 screws. Plug in the new board and it's done! You can source the parts from a place like shopjimmy or discount merchant. 3 boards were like 200 bucks. 1 board is like 100 bucks. Labor took me 15min. Think about that the next time an electronics repair place charges you 1000 dollars. Of course they check everything (Yeah right) and warranty their work (I don't) but if you check the service manual it states that this is the most common repair. Look for the Canadian manual online. Hope this helps!

Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.
