LG 65Uh5500, problem with led backlight, with flashing logo, here is the solution.

This video is for all LG led TVs with flashing logo."Please don't attempt to repair it your self if you don't have experience" also make sure to replace all the led set with same models. Don't replace just the bad one, you might have the same problem after wile.
