horizotal lines like this are most commonly caused by a bad panel (failed gate drivers on the LED driver board). Check to see if you have thin ribbon cables entering the side of your TV (those come from the driver board and enter the LCD screen. Those are bonded to the panel. Apply some pressure on the ribbon cables that corresponds to the area where the line is. If those lines disappear, it is possibly a failed bond. Those are hard to fix permanently without the proper tool but sometimes a tightly applied strip of clothes tape will restore it for awhile.

@seafury no. The ribbon cables are on the inside of your TV.
