    Samsung UE55JU6800kxxu Dark Screen Issues

    Have a Samsung UE55JU6800kxxu that is darker on lower half of the screen, more noticible on solid black, or solid white images.

    Quick google search showed reviews on these TVs, that were far from glowing lol.

    Seems a common thing with them, my question is, am I looking as gradual Panel failure?? Or perhaps just dying backlight LEDs??

    Ive attached some pics (including one of the TVs built in picture test thats the first pic of the seaside setting) and have tried to capture best I can, but as the problem isnt really terrible (yet lol) its quite hard.

    Any input, advice, opinions greatly appreciated

    Looks like a couple of LEDs are out.

      Thats what I was thinking, just wanted a few opinions before I remove a billion screws and try not to break the screen removing it lol, doesnt matter how many I do, its ways a heart in mouth moment removing more than a 40" lol, never found cardboard so useful.

      Any recommendations of the best place to purchase this LED type for both quality and reasonable pricing??

        It's advised to replace all of the strips with new, the thought being all of the other LEDs are worn out, just not yet dead. I use Aliexpress for both new strips and individual LEDs.

          Yeah I was going to replace them all m8 whilst I was on, as Im keeping this TV to go in one of the bedrooms, so want quality LEDs too with keeping it, I only gave £40 inc. delivery for the TV so dont mind putting a few quid into it.

          Id be looking at buying individuals as thats what I usually do, although if the strips could be bought as cheap would just buy them complete.

          Any idea whats the correct LED for this model so I can order them up before I strip it down?

                    Pulled it apart this morning, only top half was illuminating.
                    Tapped on the strips at the joins, and on they all came. Hot glue gun to the rescue, TV is now resembled and fully working.

                    Many thanks to everyone who took the time to reply and advise. Much appreciated

                      I would put in jumper wires just as shown on the video.
