    panasonic TX-P50V10E 6 blink led problem

    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 back with results as soon as possible.

    ok, here we go :

    The screen doesn't turn on at all, but I do hear some clicking sounds from the relays when I plug it in, so something is trying to start up.

    I've done a bit of research, but now I'm lost and not sure how to proceed.

    Here's what I've observed:
    • When I disconnect the power cable in the green circle (going to the left board, TNPA4782AF, marked in blue), I get a 7 blink error.
    • When I disconnect the power cable in the orange circle (going to the right board, TNPA4783AF, marked in red), I get the original 6 blink error.

    From what I understand, this could mean the right board (TNPA4783AF) is faulty, since when it's disconnected, the error doesn't change.

    I've carefully inspected both boards but didn't find any visible damage (no blown capacitors, burnt areas, etc.).

    Could the issue still come from the power supply board in the center, or something else entirely?

    If anyone has the time to guide me or suggest some next steps (like voltages to check), I'd really appreciate the help!

    Thanks in advance!

    i wanted to edit but seems like i cant now, sorry for double post.

    i've just removed the right card and redone the pads because they were trimed, but nothing changed.

    here is a little pic of it after



    i've also noticed there is a green led fading after some seconde near a blue capacitor marked with a red "here" above​

          Not worth the effort, this plasma uses 590 watts, the typical 50 inch led tv uses 72 watts.

            I understand but I would like to fix it anyway, instead of throwing it if it can be repaired

              There are different theories on the subject, I believe the group that says global warming is causing most of the extreme weather that has been going on in the last number of years. At least 28 killed by tornadoes yesterday in the U.S. And that's just one day. It doesn't make sense to keep these heavy old dinosaurs going, big energy hogs and only able to display 1080p. It's true a lot of them lasted quite a while but from what I have seen, once they get old, you fix one thing then another goes soon after. No doubt because they run hot and work hard so after all that time something has to give out. Also hard to find new parts that are not counterfeit and used boards are all going to be old and probably nearly worn out too.

                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 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...

                (Another) 7 BLINK TC-P60VT60 Panasonic - NEWBIE
                by SentraDude
                Greetings from SoCal I am new to this forum but not new to forum world. I come from Automotive end of side which is my main passion in life. Give the automotive nature, I love fixing and restoring things and I have in the past fixed many simple electronics, soldering, etc.. but this is a bit more involved so I found this forum, and I am very glad I did.

                I picked up a Panasonic TC-P60VT60 with the 7 BLINK error.
                Upon removing the back plate I found spider webs, dead spiders, and an amazing amount of dust. I did my best to clean the surface of the boards with a portable vacuum...

                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
                ...
