    Panasonic TCL32C12 13 blinks on red light

    I picked up a Panasonic TCL32C12 which has power but no picture. My research led me to discussions that the blinking red light is for diagnostic purposes.
    My tv blinks 13 times which is a A board issue. Does anyone else have this model OR has anyone fixed this board without buying a new one?
    I uploaded a picture an A board for reference.

      I didn't post that picture of the power supply because what I found pointed to the A board. I'll post a picture If it will help.

        I just repaired a Panasonic that had 13 blinks, what I found was 2 pennys stuck into the SD card slot, i unplug the cable going to the sd card and the tv came on. this was on a th-42px75u

        I have replaced these A boards in the past under warranty but never repaired them, if I recall panasonic did'nt even want the old boards back because they were'nt repairable.
        here is the error code for a tcl32c22
        Blinking times Contents BOARD
        1 BACK LIGHT_SOS P BOARD
        3 PANEL POWER_SOS A BOARD

        9 SOUND SOS A BOARD

          Darn. I'll try my multimeter on various components and take a chance. Purchasing a new board will be my last resort.

            The diagnostic blinks for this model tv is great. The 13 blink code for the A Board is absolutely correct. It gave me a starting point of where to start looking.
            I opened up the tv and went straight to the A board. Within a few seconds I found my problem. The solder joints on what looks like a fuse were broken.
            I resoldered it and that fixed the problem. The repair was done in minutes. I may not be as tech savvy as some of the vets here but I'm trying to contribute and share my experience with the site.
            In the pic I circled the fuse in red.
            THANKS AGAIN TO THE PEOPLE OF BADCAP.

              Theres a reason why fuse blows. On a common case, Something else is faulty then for safety reason these fuse blows. U might have jump cable these fuses and the set works but im afraid something else might blow straight since the fuse is directly shorted. U might wanna double check the circuits and the voltages if all is in correct order.

                Great job locating the problem, that component looks like an inductor. That section with 3 round inductors are for switching power supplies. That inductor looks like is for feeding B+ to the three 8-pin MOSFETs.

                  That little component didn't blow, it was a bad solder joint that broke. The tv is fine. In fact I just connected it to my pc and its working great.
                  I'm using it now as I type this.
