    Samsung P2270HD backlight problem

    Hi all and thanks in advance to anybody will support me in this moment.
    I'm from Italy and i'm not engineer or eletrician but i like electronics and i understand a little bit of it.

    Anyway that's my problem:
    (I think images can ne clearer than words)
    My monitor/TV got an intense and wrong backlight that prevent it from showing clear black, as you can see in the pictures down. All i can get is grey colour instead of black, and every image is ruined.

    I did some search on the forun and i got that, maybe, the t-con card needs to be changed with a new one, what do you think? I'm going go open the case to take detailed pictures of inner parts...

    This isnt a backlight fault, this is either an Lcd failure or Tcon failure. What Tcon does it use ?

          As it's a 22", the tcon is most likely integrated,and directly bonded to the chip-on-film drivers,and thus not replaceable.
          I would think replacing the panel (screen) is the probable only option.

            Here is everything i found (apart from The power board).
            It seems that t-con is integrated....


            In addition, I noticed that when I close a window, its trace (like a shadow) stays in the place for hours, also after removing power.

              Can you confirm there's nothing i can try?
              Reffering to replacing LCD panel.. Is there any model you can suggest to me?
              I found a panel (T220SW01V.0) with 1366 resolution, do you think i can use it (The original one is 1920)?

                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 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.

                Samsung UE55H8000 Backlight Power Problem
                by Bloopeta
                Have a Samsung UE558000, which I thought was just going to be a straightforward backlight replacement, as the screen was dark in the middle.

                After stripping it down, I noticed it was exactly the same lights out on both sides (see pic)

                I tested the strips with LED tester, and no bulbs were out, so I tested the voltage going to the strips, both at the board side, and at the strip.

                On Blue, there is 30.5v on pin 3 and 9, but nothing on the others.
                Same situation on White, 30.5v pin 2 and pin 8

                All caps look ok, anyone any idea?...
