    Samsung UA48H6400 Backlight Problem

    Hi

    I have a samsung LED TV ua48h6400. With a back light problem. Checked the Leds and found they all light up. When reassembling set I switched it on with the Screen to TCON collectors not plugged in. On checking if both connectors are plugged in. LEDS do not light up but with either one conneccted singly the Leds are on. Is this problem being caused by the screen?

    Thanks

    Jim

    post a picture of the resulting display with either of the cables disconnected and also feed in a signal. That may indicate whether there is a different issue that the led backlights.

            Samsung UE32D4010 Backlight problem, led ok
            by fanaticgames
            hello I have a backlight problem on this TV, if I unplug the cn201 cable the backlight works perfectly and the voltages are 13v if I connect the cn201 cable the backlight goes off and the voltage drops to 12v, I assume it's a motherboard problem, the question is has anyone had a similar problem? I want to understand if the motherboard is repairable or it's not worth wasting time...

            Samsung BN44-00284A Backlight problem
            by sandinemail@hotmail.com
            Samsung BN44-00284A in a Samsung LE40B755 TV bought 2009.

            In November 2020 the TV didn“t turn on only flashing red diod on front off TV.

            I then opened up the TV and found bulged capacitors on the inverter/powerboard.

            I changed all capacitors except the main two 450V 100uf capacitors.
            The TV has worked pefectly since.

            But this week it started to turn off the backlight. Audio on TV still works.
            Sometimes it turn off the backlight after 10 seconds but sometimes it works for hours.

            Any suggestions on what might...

            Samsung ue55nu7096u - no backlight - faulty LEDs?
            by ohren
            Hello,

            I'm looking at a Samsung model ue55nu7096u that I've only ever seen in a non-working condition, i.e. I don't know if the failure was progressive or instant.

            Symptoms

            No backlight at all — LCD and logic board are working normally. Resetting all settings and installing system updates has no effect.

            I tried reseating the connectors between PS and logic board, and PS and panel. No difference there.

            I could not find a service manual.



            Measurements when powered on

            Bulk cap: 388 V. Stable....

            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.
