      I now call it the 10 blinks of death... when i went back and looked at the boards they were all rusted and corroded; turns out the unit was used outside... the panel itself is like a gas lite light bulb it has and has x-amount of life to it too... Im going out on a limb here and going to say your panel is shot....
      We've already proven the sustains and panel are good in this at post #31.

      Something keep in mind is just because a TV was working before the screen is smashed does not mean all boards are good. Quite often if it was running it damages the buffer boards which then could also blow the sustain.
      A number of boards can cause SOS10 including SC boards.

      What model panasonic was the one you talk about? Do you still have it or has it gone to TV heaven?

      It always interesting to come across new unusual faults, did you ever post that TV story in here?

        If you want to try something random, put the original back in and leave A52 disconnected which should go to the GS board and see if still 10 blink.
        I cant find a52 i can find a53

            it was a long shot in desparation, there has been 10 blink with shorted SD slot with coins being stuck in there shorting the 3.3v line.

            i really think get the other A board off the seller and see what happens. If it's the same deal I don't know what to suggest really.

            With the new A board, the front LED is on and starts normal, like red to green? With the new board, when the TV is turned on is the red optic fibre out on the HA board below lit red?

              yeah with the new board all is ok its as if it should be on led normal and optical, i have a feeling the replacement board will be the same as i don't have much luck with repairing Panasonics lol

                The fact that a TV encounters failures does not make it an unreliable TV!

                Panasonic panels are well known to suffer 7 blinks on the 2007 models. What's the actual failure rate? According to someone in the industry, less than 2% due to panel.

                Older Panasonic SC/SS on these models are extremely reliable; I've heard of maybe one SC failure, one SU/SD failure, and no SS failures. That's compared to the hundreds of P board and A board failures they have.

                The design isn't deliberately unrepairable: you tell me how you can connect 5760 lines on a panel just 40 inches wide using conventional electronic connectors. That's 0.2mm pitch with NO gaps between connectors. Plus routing these connections to the address driver ICs. Yeah... it's not going to happen.

                Any TV in an environment where it is on 24/7, exposed to cigarette smoke/moisture/dust/salttwater, etc. will of course last less time than an ordinary TV. This is common sense! LCD and plasma alike...!

                10 blinks CANNOT BE CAUSED BY A PANEL PROBLEM!

                The only blink codes for possible panel problems: 5, 7 and 8.

                    Agreed proprietary garbage; its no wonder panasonic got out of the plasma business...

                    I no longer invest in trying to fix pani units anymore; too few, not enough interchangability; nice TV not worth the time to fix to me; hunting down parts is a pain...

                    I will crack open the POS pani unit again and see whats the deal but to me they are a crap product x-sys ribbons tear so easy; the screwing down of the ribbon is the most retarded thing i have ever seen too...

                    if any of you guys are in south florida i will give you a great deal on the pani parts..! LoL good riddance to Panisonic..!

                    If you ask me anything with LG or samsung guts inside are the units to work on and save cause parts are available... Panis are shots in the dark; I mean just read this thread how many shots in the dark and no hits already..?

                    Time is money and to continue to invest in a device which can be replaced for the same price makes it NOT WORTH FIXING! LoL

                    Update cracked open the unit put the y-sys ribbon back on fired it up 7-blinks; when i first got the unit with its original boards in it, it was 10-blinks after swapping all my good known boards over got 7-blinks... So even if the unit starts with 10-blinks it can be other underlying issues... with y-sys disconnected it gives 6 blinks... no signs of anything fried; and again all boards came out of a working unit with a broken screen... again if anyone wants a good deal on this batch of parts let me know...

                      Hi all new main arrived and still exactly the same, no blinks powers on but no picture.

                      When I disconnect main I get a white screen and all other boards have the LEDs lit

                      Original main gives me 10 blinks

                      I'm lost now anything else I can check ?

                            Top trick that did it thanks so much tom I was ready to part it out tbh. Do you think that would have worked with the other main?

                                I think your remote isn't working... That's just how you turn a Panasonic on without a remote.

                                  Been reading through this, as I have a ten-blinker and can say for sure--It AINT the panel!

                                  I'll start a new thread as its a slightly older set 42PZ70B but was really happy the panel Appears to be good.
                                  (Its original owner had well 'got-at' this poor thing, got PSU running now, and its ex-owner had left the plug just above tuner out.
                                  This gives panel initialisation and the usual glow--with nothing on the screen however, plugging back in--Gives 10-Blink --of death?--Nah!.....)

                                      Yes - they always run at a low speed. Normally.

                                          Normally, these sets will turn on for about 10-15 seconds then shut off if the fans are not spinning. There is a feedback circuit which will notify the main board if the fans are stuck (jamming, broken fan, cable loose etc.) So it's odd that the detect circuit isn't working...

                                            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 TX-P50V10E 6 blink led problem
                                            by Vebririon
                                            Hi everyone,

                                            I'm new here and trying to repair my Panasonic TX-P50V10E plasma TV, which is currently showing the 6 red blink error code.

                                            Just for context: I'm used to building PCs and installing modchips in old consoles, but this is my first time trying to fix a TV. I'm French, and while my English is okay, I'm using ChatGPT to help translate and clarify my messages as much as possible — so please forgive any odd phrasing.

                                            I'm also not very experienced with using a multimeter, but I'm very motivated and ready to follow instructions carefully and report...

                                            Nikon D800 camera - flash don’t work and capacitor don’t charge
                                            by corrize
                                            Hello, I'm stuck in troubleshooting…
                                            The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.

                                            In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
                                            When I press the flash button, it's detected by the system, flash icon appear on LDC display....

                                            by James Jackson
                                            I usually try to figure these things out on my own but am asking for help now as I have been beating my head against a wall.

                                            Backstory, I initially ended up with a CF20 Mk2 with a locked BIOS. I used aptio to read the BIOS and made the adjustments to the .rom file and attempted to write it back with aptio before reading other users problems with that setup. Well it bricked the BIOS go figure. Computer no longer boots, black screen. I found a clean BIOS on this forum but now I am having ME issues. So I would rather hand over the aptio dump(pre BIOS brick) and a hardware reader dump(post...

                                            Panasonic TH-42PZ800 8-blink error mystery
                                            by nervx
                                            Years ago my tv gave a 7 blink code which turned into 8 during diagnosis. I had ordered a replacement ss board but somehow the tv started working again and i never used the board. Now a week ago my tv flickered and shut off at random and gave the 8 blink error code. The same issue it had all those years ago. The only difference this time is that over the last few months there has been some purple and green tinge that comes and goes in more solid colors such as white.

                                            Anyway i checked all the screws and replaced the ss board with a known good one and still got 8 blinks. I saw a...
