well i just bought this machine and i didnt notice it when i self tested the dot matrix,but the very bottem row of it is out all the way across. is this a sign of outgassing or can i fix this and any ideas how to fix it or who might fix it.i did try reseting the ribbion cables with no luck.i posted a pic too .the other dots in the pic are just a reflection.its just perfect but the bottem row. thanks

That's not outgassing - that's either a signal problem, or a power issue on one of the lines going into the glass of the plasma display.

If you remove the DMD video signal cable (the grey ribbon cable that goes from the DMD driver board to the back of the DMD panel) and reverse it (swap ends), does the line out change?
