I have a LG DU50PX10C with a black vertical line
Plasma televisions have anywhere from 24 to 40 drivers that control the individual rows of pixels comprising the screen. Should any of those drivers fail, the screen will display a 2 or 3-inch black vertical line, and probably shift the image to one side or the other. Driver failure is considered a manufacturing defect, and is not preventable by the owner. In some instances the line can be caused by faulty pixel ribbons that run top to bottom, either faulty of just loose in their connectors etc.
Then there are Stuck Pixels, Pixels become "stuck" due a failure to turn on from its standby state. Occasionally, these pixels die in rows, spanning the full height or width of the screen, or be only a few inches long. These "dead" pixels can turn on randomly, or stay a different color other than black. This is an issue caused from the wire filaments inside the panel failing, or an offshoot from a driver failure. Impact to the screen can cause a row to stick as well, even if there is little to no external indication of damage.
However, in most cases, inspection by an engineer is usually necessary to diagnose exactly what has caused the fault, unfortunately this can be an expensive prospect, not to mention the potential for a painful bill for the repair alongside the inspection fee. If your TV is in its warranty, don't hesitate to claim on it.
I hope this helps you, or at least gives you a better idea of what you potentially could be facing. Good Luck.
