Try soldering up the driver boards. They run pretty hot and can develop cold solder joints.
Where's JohnCT? I think he's an expert on these.

With a plasma, a single horizontal line is either the buffer board (95%) or the display itself. I can't honestly recall seeing a display itself cause this but some training manuals over the years mention it, so I am as well. John |

A little update: the line is still there, and has not grown, moved, or otherwise changed at all. Definitely a fixed anomaly. I'm a bit concerned about it affecting the panel as far as burn-in is concerned.

I actually wanted to go that route (replace the entire buffer board) but none seem to be available. Alas...

Part number LJ92-01729A A couple of caveats. The 50C550 is a 1080P panel and the ribbons from the panel to the buffer board are a bit difficult to remove and difficult to seat in the connector. When I install them, I use an Optivisor to make sure the ribbon's two notches are seated fully down in the connector. They may look good at first but when you see them with magnification, you'll see what I'm talking about. If you're nearsighted then this won't be a problem. This board was marked good by me which means it was either pulled from a running panel or tried in another panel and verified, so it *should* be good. If you want it, it's yours for the asking.
