Re: LG 42LE4500 lines on screen

I have Lg 42Le4500 for about 4yrs and in recent weeks it started to show some lines on the left side of the screen, in start they were appearing intermittently on one side of the screen but now they are of a constant feature on the left of the screen. Saw few youtube post but of no help.

Can someone advise what is the issue and it it could be fixed. can post photos if that would help.

Many thanks
