    Panasonic TC-P50G15

    Ok, so I finally figured out that is was the SD board that was giving me the 7 blinking lights. I got a new one and installed it and now I get this on my display?? Could this mean my panel is bad or something? Or something else I can look for causing it??

      It looks like D board or buffers to me. If SD died, SU could have too...

          Well, thru my dumbness I replaced the SU already as well. Bc I thought that was the cause at first. So the D board or buffer boards?

              The buffers I refer to are SU/SD. So I think it might be D board. On this TV I believe the A and D are integrated together so it is one board to replace.

              Did TV just die, or did you pick it up broken?

              If it just died, it is far more likely you got a faulty SU. Someone else on this forum had a similar problem with an LG, he got sold a faulty one, and found that it had a similar fault to his original failure. Try with your original SU. I know a bad SU can cause the whole screen to mess up, whereas a bad SD usually only messes up the bottom half.

                  Yea I got it from a buddy of mine who said I could have it if I fixed it.
                  I just replaced the SU board back with the original and still same picture on screen. Is there a way to test the A board?

                      Originally I had 7 blinking red lights. I isolated most boards such as, SS,SC,SU,SD and discovered that the SD board was the cause of the 7 blinking lights. Replaced that and TV turns on but with all that crap on the screen. Hope that might help.

                          I don't know of a way to test the A/D board, sorry. I cannot be 100% as Panasonic TVs are hard to diagnose sometimes.

                                  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 hereπŸ€”?
                                  Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting πŸ˜‚.

                                  by AquaMan Ua
                                  Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

                                  I finally got one too! a new monitor! and my first ips panel to boot!
                                  by ChaosLegionnaire
                                  after bigtroll managing to score a new video card in this thread, i thought i'd get a new monitor too, since my current one has a bubbly and blurry screen that i posted in this thread.

                                  i tried numerous local websites to get one but many required a mobile number to sign up which i dont own. i also had issues finding the right monitor that met my requirements. it was a nightmare finding one, spending weeks looking through g00gle.

                                  finally, i decided to try lazada, the singapore version of jack's aliexpress. it only required an email address for signup, but whenever i...

                                  So I've had this monitor for probably a decade now, and it's finally starting to fail. Began with a little sporadic flickering, then eventually started going black (power LED stays blue, can still see image on screen with flashlight). A power on/off fixes it for a bit, but then it happens again. Once it got to the point I was dealing with this every few minutes, I opened it up and just replaced all the caps (minus the big one) on the power board with new Panasonic ones. All the old caps tested fine on an ESR meter, and this worked for 5 days. But the screen just went black again today, so...

                                  Hi everyone!
                                  I happened several times, in the search for help from the web, to consult this very interesting forum.
                                  So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.

                                  Having said that I come to the gist of my post on the forum as the title suggests.
                                  For my passion for technology I'm now collecting several...
