    Samsung UE40D6530WS Led TV main board repair

    Hello all.
    I need help with a Samsung UE40D6530WS Led TV. It has no picture and sound, red indicator blinking and clicking sound is heard. There is backlight, but the screen is black (I can see it in a dark room, as the TV tries to start continuously).
    The local TV shop said it needed the main board to be replaced.
    Is there something I can do to repair it, rather than replacing it?
    Some components I can check that are more typical to fail?

    Pictures:











    Best regards,
    Milen

    I decided to replace the two electrolytic capacitors on the main board (third picture), but I am not sure what replacement to get.
    The markings are:

    22564
    100
    350

    Any help would be appreciated.

    Regards,
    Milen

      You cant use as replacement for the two electrolytic capacitors 100uF 35V :
      EEEFK1V101XP, EEEFPV101XAP, UCD1V101MCL6GS , UCD1V101MNL1GS.

        Check with an Oscilloscope the LVDS signal. While you are at it check all the voltage regulators and then the caps for excessive ripple.

          Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
          by Asraf Atb
          Hi everyone,

          Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

          Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

          I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

          Samsung UN75RU8000FXZA bad main board?
          by Lee M.
          When plugged in it will click and cycle the BL on and off, no pic and does not respond to remote. When I disconnect the cable from the PS board to the main board and then plug it in the BL will come on and stay on. There are only two boards in this set, the LVDS cables from the panel driver boards connect directly to the main board. Since the BL comes on and stays on I'm thinking the PS board is ok and the problem is on the main board. Should I order another main board or do I need to do more testing? thanks, Lee

          Issue: No Power, Then Rebooting After Main Board Change

          Short answer: replace main board and power board
          Technical answer: replace main board and Q306 & Q307 on power board.

          Long answer:

          TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....

          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't

          Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
          by cheeky2
          I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
          Obviously the same LVDS connector for the screen connection...
