    Much confusion over one Panasonic TCP50S2 board

    Hello,

    Hoping there is still someone around that works on Plasma's and knows specifics about the 50S2... I bought one used with issues and want to replace the A board. Service manual says board model number is TXN/A1LQUUS. So, I look around and find a used pull from a working set(came from a TCP50C2 but said it was compatible). I get it home and the board is identical..., except for the ribbon cable mount. To of the three are a different size. My S2 are wider than the board I received. After looking on the internet, other companies are selling the same thing.

    https://www.tvpartstoday.com/TXN-A1L...sh-a1lquus.htm

    What gives? If i can attach a picture of my board I will but would anyone know the issue here? Did they make two different boards for the same model year? Thanks in advance for any help!

    It is likely the board would work "electronically" but the cables are different, Your model has the connectors mounted on the other positions that are available when it was manufactured to be used with a different main and cables
    So main board and ribbons would also need to be replaced

      Hey GLE3
      On a side note, I too bought a used a board from tvpartstoday, last week, for my Panasonic plasma tv, Tc-p50s30. They sent me a board with the tuner jack ripped out! IMHO, I don't trust them. Luckily I went through eBay so if tvpartstoday won't refund my money, eBay is supposed to. I'm waiting for refund.

        There is a TNPAXXXX number that your board would carry. That is the number you are to match. Ask for a refund and get another board from a different supplier. Once you tamper with the board they will not give you a refund.

            Thanks for the heads up on tvpartstoday, their reviews are limited out on Google.

            In my case would that be a TNPHXXXX number? From what I can tell they are the same....

              'TNPHXXXX' number is the Blank PCB (Printed Circuit Board) P/N not the PCBA (Printed Circuit Board Assembly) P/N.
              Blank board can be stuffed in many ways to make a bunch of different PCBA's as you can see from the board that you bought which uses the same blank board but it is stuffed with parts for other TV model..

                +110. So the TNPH No. matches And yes that is blank PCB No.

                  Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                  by Tynan Dill
                  I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                  Upon bringing it home and plugging it up, it showed a standby light.

                  I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                  The screen seems to blackout and stay black, but with a flashlight I can see the display.

                  With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                  by m1ch43lzm
                  Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                  Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                  Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
                  by sam_sam_sam
                  I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

                  This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

                  Panasonic TC-P54VT25 No image. A or D board?
                  by canadaboy25
                  I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

                  The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

                  I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...

                  TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                  by howardc64
                  All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                  • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                  • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
