The LG plasma TV with the black vertical bands, may be the bad connections, you can try to reconnect the cables on the X board. If the bad connections on the panel side, you need to replace the panel.

SOURCE: got black line in the middle of my 42 inch plasma screen

Perform the following tasks:
Determine if the "line" is an external cause or internal.
By external, it means a result of the interface, cabling or other boxes that are connected to the set.By internal, it means a defect within the hardware or software of the set itself.

Do find out you must disconnect everything but, say one video source. The best would be to unplug, pull everything from the back or front of the tv .By a process of elimination you should be able to convince yourself the source of the vertical line is external to the tv or internal to it.
Then, once you have decided that, you can attack the place that is most likely to be the source. For example, some of the early sets had some non-standard processors and had to be upgraged to the new standard after they were purchased by the consumer. It had to do with the HD and HDMI interface connections, but could have effected other stuff. Also, some S video inputs have glitches in them.

SOURCE: Have LG 42 inch plasma, 1 inch black line down

Sounds like the middle scalar board is defective. Since the issue comes and goes it could just be a loose connection to the between the scalar board and the PDP Module (plasma panel).

Great caution needs to be taken when checking this connection because it is a ribbon cable connection it and needs to be put in correctly aligned or it could cause a short in one of the circuit boards.

Hi I have a LG RZ42px11 there are 6 vertical thick black lines running down the middle off the screen, when cold the TV seems OK but if it has been on for around 10mins or on standby the lines stay on screen.

Thanks.
