I solved the same problem by replacing my digital board. Cost $118.00. Been working perfectly for several months now.

If it looks like a pin or magic marker drawn straight down the screen, it most likely is a de-laminated flex cable to the glass, if it is the panel needs replaced.

Chances are really good that it is the LCD Panel.
If so, cost of repair would exceed cost to buy new.
Give LG a call and see what they may be able to for you. Their Customer Service number is

It is hardware issue related to LCD Panel (screen).
Regarding fixing it, it depends if you are handy with electronics stuff repair and can replace circuit boards in tv etc then please check T-Con (lcd controller board) on top center position at rear of lcd panel, this board would be covered with metal shield. Need to take off back cover of tv to get access to T-Con board. If T-Con board does not solve lines problem of screen then LCD Panel is bad and will be replaced.
If you fee uncomfortable doing so then repairman option is better choice.
Hope this info will help you.
