    Been searching for months to figure out where I stand with a UN556150 . . .

    I have a UN55SE6150FXZA that doesn't have a picture and no sound, but reacts to the remote. I get the 5 start up blinks, but when I pull the power I get a 5-5-4 in double blink sequences. I can't find anywhere any listings for Blink Codes. I know that this model is most susceptible to the cap issue. But would really like to get this thing fixed. So I can take my time in rebuilding my DLP.

    Any assistance will be greatly appreciated.

    Thank you . . .

      'UN55SE6150FXZA' You need to verify the mode.

      UN55ES6150FXZA?
      There are more than one version of the boards so we need good clear pictures.

        We have seen this model come into the shop many times with bad LED's and never seen bad caps on it. Disconnect the main board from the power supply and see if the back-light turn on. If not then we know for sure its going to be power supply and or LED strips.
        Once the power supply has had time to discharge, connect the main back in and perform the flashlight test. If you can faintly see the picture in a dark room by using a flashlight at a 45 degree angle about 2 or 3 inches from the screen, then you know your issue is backlight.

          I think if the Backlights have a fault the set may shutdown. So if disconnecting the Main Bd from the Pwr Bd gives backlight, then Main Bd faulty. However, if the result does not give backlight the Pwr Bd or Backlight is the fault....In most of my encounters the Backlight LEDS were bad.
