    Sharp LC-32D64U Blink Codes

    I have a Sharp TV that isn't turning on. After plugging in, green front LED turns on and then after about 20 seconds flashes an error code of power and OPC together and then power LED only 2 more times.

    Service manual here

    If I am interpreting it right, then it is a PS fault but then there is a secondary blink code on a notification LED. Not sure where this notification LED is. Confusing.

    I checked a similar manual and the it looks like the notification led is the same as the OPC led
    You said:"flashes an error code of power and OPC together and then power LED only 2 more times"
    so how many times does it flash power and opc leds together?

      The power and opc leds flash once together and then the just the power led two more times at the same rate. Pause and then repeat.

      I took the cover off the main board and there is a led flashing there as well. Looks like the TV is failing to turn on the backlight. When first plugged in, I have 15V from PS and PS_ON from the processor. The led on the main board flashes about 13-14 times, there is a relay click, and it repeats 3-4 times. The 15V then shuts down and it flashes the codes in the front.

      The PS error codes are misleading since there are regulators on the main board and the PS fault codes deal with these internal voltages and not the PS board.

      Still investigating. Thinking possibly inverter board or lamps but this fault doesnt match the error codes.

        Found post here which describes the same symptoms and it was fixed by replacing the main board. 32" TV's aren't worth that much so not worth replacing.

          Have you tried going into adjustment mode, Hold down VOL(-) + input then plug in the tv and see if gives a picture,
          If the Lamp Error gets too high, the tv will not turn on.
          Also Remove the inverter board and check the ground screw connections, If they look black and arced, try cleaning them, then going into adjustment mode and reset lamp error.
          I also recall this model did have some main board issues

            Reinvestigating this, power LED blinks 3 times which is communications error. OPC is notification LED and 1 blink indicating error on startup.
