Samsung Plasma Black vertical bar on left side

[2hamburgers]

Model number s42ax-yb07, mfg:2009. So here is another broken TV i bought that I already repaired once. I bought this tv with a now power issue and ended up replacing the X-main (only) with an ebay card. It worked great and I sold it to a friend. About a month later it started doing this. Visually, everything looks ok under the back cover. What say you BC Forum?

Either a loose connector on the appropriate X DRIVER connector.
Or the plasma panel is bad.

Make changes only to these connectors while the TV is unplugged, failure to observe this may lead to damage to the panel.
