    Panasonic TH50PX80U 7 blinks

    So I got this Panasonic TH50PX80U for free today from a friend with the 7 blinks and followed the SD/SU/SC elimination and narrowed it down to SD. Amazing got test results laid out just as they are in the pictures in service manual, now I am a automobile mechanic and it is rare to get that, I will take it. I get a Picture and no blinks with SD disconnected. Is there anything else I should look for before replacing SD board, or is there a common failure on the board that I can go after.

    Got to give you guys thumbs up on this thread that helped a lot,

    Thanks.

          A common issue on these sets, replacing SD should sort it right out, and then you can enjoy a nice big plasma.

                      Parts for these are quite cheap - many of them die only because people smash them. Usually everything still works until the Wii controller hits it...

                                  No reset needed.
                                  SD board has some screws and connectors going to the SC, and to the panel. Be extremely careful with the connectors going to the panel, they cannot be replaced.

                                          Yes, also try with SU, though you might not get half a picture with SU out.

                                              Yes All I did was disconnect from SU ( 20 pin at connection SU11/SD11unplugged flat ribbon cable) then disconnect from SC (unplugged flexible hard wire SD42/SC42) Ran the jumper ground wire from circuit L801 to one of the floating ground bolt holes and it turned on. This works for SU test also.

                                              Installed my 11.00 used card and TV looks great, been on for 3 hours now.

                                                  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 😂.

                                                  Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.

                                                  Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner...

                                                  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...

                                                  Hello,

                                                  Stopped by this site trying to fix my parents Panasonic Plasma TV.

                                                  Model number is TH-50PZ85U

                                                  Power comes on and the red power light stays on solid.

                                                  Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

                                                  I also hear a few clicks.

                                                  I also think my parents said there was a thunderstorm and the TV failed after that.

                                                  Section 6 in the service manual talks about power and no screen,...

                                                  Hello all,
                                                  As the title states, I followed the troubleshooting guide located here: https://www.manualslib.com/manual/23...page=53#manual, which concluded the 'A' board needs to be replaced. Looking around the net and eBay, I see that there are repair services for the board (TNPH1043UE? Not sure if it is a 'UE' as the suffix grid does not appear marked). What additional troubleshooting can be performed to ensure 1) this board is the problem and 2) since there are repair services, what are they fixing on the board?) I expected 3.3V not to be available anywhere...
