    Panasonic TX-P42GT30B 7 Red Blink Code

    Hi All,

    A neighbor has contacted me about their 10 year old TV that does not power up but just gives the 7 red blinks.

    Before I commit to taking the back off do you have any thoughts?

    Many thanks

    Nev

          It's not that hard of a repair. Usually 4 shorted igbt's on the SC board. Take a continuity reading across the 2 pins of the power connector (unplugged) on the SC. If your meter beeps, you have the shorted igbt's. Post a picture of the SC board. Also, see how many of the mounting screws are loose.

                  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 TC-P42ST30: Repair for 14 blink code
                  by LongLiveMyPlasma
                  My beloved Panasonic TC-P42ST30 has been stricken with the 14 blink code.

                  I've spent many hours reading through forums, watching YouTube videos and reading the Panasonic plasma troubleshooting guide. But I'm a novice at this, and still need some help to cross the finish line.

                  I understand the Panasonic troubleshooting guide suggests that the 14 blink code usually means there's a problem with either P-board or A-board. However, I also learned the problem frequently rests with the SN-board.

                  Using my multi-meter, I was able to confirm the P-11 pin on the...

                  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...
