Lg 50PX4DR-UA lines in screen

[pop70458]

I have a 50PX4DR with lines on the top left hand side of the screen.

My guess would be the logic/control board.

Is there anyway I could narrow it down to that? Do you think freeze spray could help?

Is the fault intermittent or always there?
Not much you can do re narrowing it down, although the logic board generally is the only board to process the picture in two distinct halves like that, if that helps you decide.

The fault is always there. I will order the logic board.
