    Samsung Syncmaster T240 Super Dim Backlight

    Hello all,

    I am very new to tearing down a monitor and I need assistace on how to test/know what to look for. The monitor is SO SO dim. I have read so many posts, but I feel I am in over my head in terminology and basic testing skills. I got as far as taking out the power board. Here are some pics. Thanks in advance for everyones time...

    Re: Samsung Syncmaster T240 Super Dim Backlight

    Hello. do you have a multimeter? Maybe you can start by measuring the voltages at CN2 from the bottom side of the board with all the boards hooked up. Place the black probe on the chasis and the red one on the individual solder joint on the bottom side. There is an indicator at the side of CN2 showing the correct voltages.

    P/s: This model have a history of pad inverter transformer T301.

      When you mean hooked all up, I assume you mean run power through it, correct? I understand the rest of what you saying, and I will give it a try. Thanks for the reply and I will post the results.

        I tested at the CN2, All readings were normal. Nothing was out of the ordinary. When is the next step in testing to find out what needs to be changed?

          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 UE60KU6079 backlight okay mainboard responsive, no picture, no sound
          by Ierwin
          Hello everyone,
          Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
          The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
          He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
          I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
          Anyway I still fully expect that there has been something seriously damaged...

          Samsung BN44-00807E Low Backlight
          by Warrensmith
          Symptom is dim backlight - this set came in with almost no backlight.

          Samsung UN55JU6500FX2A

          1 - Replaced all backlight LED strips (set had lots of hours at level 20 backlight)
          2 - Changed out what appeared to be a bad Q9102C on BN44-00807E - not shorted or burned but appeared to be open. I was able to read (with difficulty) the part number - however I may have misread it - Can someone confirm that this is indeed an AOD9N40.

          Backlight improved significantly - about like it would be set to a level 3 or 4. Setting all the way to 20 seems to...
