    Samsung UN32D4000ND flashing red light

    The power board in the TV isn't working anymore (BN44-00421B).

    When the TV is plugged in the led begins to flash.

      I previously took it to a Samsung repair centre and they said that was the problem

        What dc volts do you have on the pins of the connectors?

          The connector on the top of the picture (from left to right)
          7.2, sometimes changes to 3.6
          7.2 sometimes changes to 3.4
          Ground
          Ground
          12.6
          12.6
          12.6

          Connector on bottom right of the picture (from top to bottom)
          I'm not getting any readings on this connector

            Can you tell us what it says in the box alongside the connector and then put your reading alongside. It looks like there are 14 pins

            An example attached

                Your chart made no sense to me at all, see DB chart again on how you suppose to report the reading of each pin.

                  He once read the second half of the pins on Cnm803p. It has 14 pins not 7. Since the secondary is powered up, A5v and PSON has to be there
