It has a single vertical line running from the top to the bottom of the screen. It is about 1mm wide and is a light blue colour. It is particularly apparent/noticeable when the tv is displaying a dark blue colour. The line appeared a while ago and lasted for several months, it then disappeared for a couple of months without any intervention however the line has now returned. Thanks in anticipation.

Hello Depending how wide the line is their could be two possible causes.
I have two questions for you.
1. How wide is the line.
2. Does it run from top of screen to bottom of screen?
If the line is thin a single strait line then it is possible the PDP has gone Bad (Panel). (Screen). The screen will to be replaced.
If the line is at least 2 or more inches wide then its a buffer board which can be replaced. LG calls this board Hand insert Boards or display driver boards..
Both sound like bad LCD panels. The following must be answered to confirm this: Do the lines appear on all inputs/all signal sources? Can they be seen in the OSD/menu? If yes to both questions, it is likely that the LCD panel is bad
I was not sure if the line was going from top to bottom or left to right. the X driver board is for left to right and the Y board is for top to bottom . The Y driver board is a common issue with these sets there is a Y main board and a upper and lower buffer board for the Y axis
