    Samsung QN65LS03RAFXZA (65” The Frame) Backlight Repair

    One quarter of the TV's backlight is dim. I bought the following replacement LEDs: Samsung BN96-49193A/BN96-49194A LED Backlight Bars/Strips and some suction cups.

    Does anyone know where I can find a repair manual or any other suggested reading/viewing material?

    Thank you.

    There must be a mistake, an emploee of a tv shop told me that theese tv have a different type of backlight, not normal led stripes, so what are the spare parts you are mentioning?

        A qled is an lcd screen in front of a backlight led screen, that's all...

          Samsung are great at marketing bullshit. Their QLED use traditional edge lighting, SJ are correct.

            I would expect edge-lit blue LEDs and yellow sheet. Haven't found teardown of this frame TV yet.
            Agree, should be shopjimmy mistake, can't be the same strips for 65" and 75", also QLED and normal LCD/LED.

              The thickness of the screen that i was watching let me thinking the shop boy told the truth, and also the big difference in cost, i have understood nothing about this Qled so i guess i'm not of help here, but to answer the question, today's samsung manuals are more or less a clown thing, not useful. Better to watch some video on ytube..

                  I know it's a old thread but it wasn't a mistake from SJ, qleds do use normal led backlight strips, some leds are blue but some are normal white leds

                    Did you repair it, shouldn't be too hard as this model is not a slim model and the bezel on the front goes all the way round so be easier than the newer ones which have no bezel and screen is glued in

                      All QLED TVs have blue leds. They shine through a layer of quantum dots on a yellowish diffuser

                        Problem

                        This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                        Trying To Fix: Samsung THE FRAME backlight replacment - How to open display???
                        by KYBOSH
                        I came across this TV (UN65LSO3NAF) and would LOVE to replace the backlights and save it but i do not know how to access it. I attempted this repair not too long ago on a 50 inch model and cracked the display while tryjng to remove the bezel around it. Even after that display crack and i was free to do an autopsy on the remains i could not find a safer/proper way of removing the metal frame around the display. Does anyone know the trick to opening these FRAME TV displays? Im not above carefully taking a dremel to the corners but im pretty sure there is a right way to do this. I have looked...

                        Samsung QE82Q70RAT no backlight
                        by sansanpartida
                        Hi everyone!

                        Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.

                        My issue: No backlight.

                        Model: QE82Q70RAT
                        Type No: QE82Q70RAT

                        The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.

                        So hopefully, I can fix this cheaper.
