    Panasonic Viera TX-P46G10E 11 blink even after fan replacement

    Hi all,
    I have here a Plasma TV TX-P46G10E that before had a problem where it had issues with 11 blinks (FAN SOS) BEFORE starting normally. After that it works for all day long.
    It had some bad cold solder and I remade them all. After I replaced a fan that was half-dead (no RMP signal from the respective pin, but ok with 9V).
    Now the TV power up instantly and works perfect... only without the backplate!
    If the backplate is placed on the TV shutsdown after about 10min and start blinking with the 11 blinks. If I shutdown and re-powerup it starts blinking after a bunch of seconda. So I assume it's some sort of overheat protection.
    Since I don't have a thermal camera (but I can ask a collegue for it) I checked the schematic/service manual, but nothing talks about overheat protection or thermal sensors.

    I would ask you any suggestion where to check or which component to check.
    Thank you.

      After days of headhache I found that original fans have a Thermometer inside instead of a Tachimeter!
      So I made a little bypass by adding a 100k trimmer to drop the sensor voltage to about 1.20V.

      The TV worked perfectly for hours with fans at maximum rate (9V)

              Yes it would be the best, but they're becoming rare and expensive
              The only thing I could suggest is to see on the service manual, if any, if there's a specific code because I don't know if the thermal sensor changes between the fans.

                      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...

                      Panasonic SA-XR25,Looking for a good replacement cap
                      by Jagster
                      I have a Panasonic SA-XR25 surround receiver that is not working and I believe it may have a faulty capacitor. This large capacitor near the mains power input has a plastic top that is bulged out. Anyhow, I'm trying to find a like replacement but Panasonic doesn't seem to make this capacitor any longer and I want to find a suitable replacement. It has an "AUDIO" designation written which I presume means something important in relation to the capacitors design characteristics. Can someone advise on what would be a good replacement? Image attached.

                      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 Viera LC470EUN (SE)(M2) T-Con issue?
                      by Ama Chur
                      After watching some youtube videos and checking some forums, I'm at a loss. With both ribbon cables connected, we have no image. With the left one pulled out, the screen is black and white, split down the middle. With the right cable removed, it is all black. Backlight is working fine and we have sound and can open applications. We are strapped for money right now and are hoping to repair whatever the issue may be. I think the TV was manufactured in 2012, so I'm aware that may not be possible. Edit: Found a single vertical line of blue pixels on the left side of the screen with one of the ribbon...
