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.

If the screen split is exactly 50/50 top/bottom You are not getting SU or Scan Upper drive.
These are lovely set to work on.
Most likely is SU board itself - Not repairable just to be replaced.
Sorry I work in the UK so I can only guide that the UK part is around £30
SU may have been damaged by failure if the PDP (Plasma Display Panel) but is 9 years only had 2 screens damage the SU board.
There are several setups to do after fitting a PDP. If you don't have the service data - Do not risk it, Reduced life of the Panel and a safety risk.
