    Re: Panasonic TX P50S20B

    just tested a couple of things just disconnected sc2 connector turned tv on with connector disconnected now 7 blinks
    next step I unplugged sc2, P35, ss11 and three white ribbons on the A board. The TV turned on and stayed on with no error blink.
    now im stuck guys what too check next

    EDIT! q661 is shorted so guess sc board fault.
    My sc is a TNPA5105 Ab would a TNPA5105 AD out of a 42 inch set work?
    any other tests too do on the other boards before replacement.

        Panasonic ZT60 plasma tv with strange behavior and 8 blink code
        by cloo
        I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
        It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.


        So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
        After doing a factory reset this problem was gone and the picture was back to...

        Panasonic Plasma repair - TH-P60GT50 - Dead, 3 blink code
        by rmacintosh
        I aquired this Panasonic 60" plasma around the time my first child was born. It was meant to be a project tv, hoping to fix it chipping away at the repair in my free time. Well that was 2 years ago and i'm really just getting around to making a sincere effort to see if I can ressurect this beast.



        The symptoms of the tv ar as follows:
        • Plug AC in to back of TV
        • After about 2 seconds the relay on the P-sub board will click on and then a fraction of a second later it clicks back off
        • The 3 blink code is given by the power LED
        • If the TV is unplugged and then

        Panasonic SA-MAX770PU SMPSU board fault....
        by Rictech
        Hello everyone. 😀

        As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
        Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

        Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
        This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
        There are no devices that have exploded or otherwise show signs...

        Panasonic plasma TX-P42ST50 - 6 blinks
        by jm1234
        Hi,
        anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
        It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
        I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
        I checked that board for any obvious faults...

        Panasonic Plasma tc-p55vt50 6 blink error code
        by orbit417
        Hi All,

        Thank you in advance for your advice.

        I have a Panasonic Plasma tc-p55vt50 that's about 9 years old and has just recently stopped working :-(

        I noticed that when I turn the tv on I hear a click then screen comes on for like half a second then shuts off and the led blinks 6 times.
        I did some googling and found several video's on trouble shooting all sorts of blink codes. I finally came across one that showed 6 blink error code but for a different model. It recommended disconnecting the SC board to determine if it was the A board or power...
