    Panasonic P50S30 14blinks

    fellas, i need your help. i have a panasonic P50S30, it went dead last year and started blinking 7x. Panasonic had a technician come change the SC, SU and SD boards, it worked. 6 months later, it went dead again, blinking 7x and this time. i'm out of warranty.

    i bought an SC board online and replaced the the burnt out one. TV went from 7blinks to solid red and still no picture. when i hold the power botton for more than 5 seconds. it starts to blink 14x.

    i've changed the P-Board, A Boards and still no picture, still solid red and 14x blinks.

    I need help or i'm gonna have to part the TV out.

    thanks

      It's usually advised to swap the SU and SD at same time as SC replacement.

          yeah i knew, but i examined the SD & SU boards and they're both brand new with no burnt marks.

              The buffers on these can fail without obvious burn marks.

                  Panasonic Oled 55EZ950E, no picture, red led blinking every 4 sec
                  by riparo
                  Hi everyone, I have a Panasonic OLED TV model 55EZ950E, as soon as I turn it on I don't have any image the LED goes from green to red LED blinking every 4 sec, I found the service manual suggests checking OLED PANEL, PB BOARD, T-CON connectors but it seems like everything ok, I didn't find any burns under the pb board
                  I attach a link to download the service manual, thank you for anyone who can help me

                  I get no image nor backlight, standby light blinks 13 times then stops. Any clues what it could be no evidence of damaged components

                  I picked up a Panasonic NH-P70G2, though it would apply to the NH-P80G2, NH-P70G1 and NH-P80G1 models as well, as maybe some other models. This one was coming up with a H86 error. After lots of testing and googling it was an error with one of the thermistors in the condenser area.
                  The attached French service manuals is incorrect, TH11 is gray and is a 95k thermistor and TH12 is black and is a 35k thermistor.
                  In my case TH12 was bad. I was able to get a 35k thermistor on AliExpress. It's 6mm in diameter.
                  Unfortunately the whole machine has to come apart to fix it.

                  Panasonic PF50G20S blinking 13 times
                  by CoinCoin88
                  Hello there,

                  Google led me again to badcaps when trying to troubleshoot a dying Plasma that is sitting at my uncle's roughly 550 km from where I am. It's an old G20 from 2010 or so, that isn't being actively used so you can consider the panel "not too sollicitated".

                  Symptoms: TV starts, works for 5-10 minutes, then screen turns black and safety kicks in and spits a 13-blink code with the red LED. Once this code kicks in, the TV will not display any image anymore. Unplug it for a few minutes, plug it again, it'll work then fail a few minutes later.

                  Panasonic TC-P55ST50 8 blinks then no blinks
                  by Andre Gilbert
                  Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
                  Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
