    Panasonic TC-P50C2 dead

    I have a Panasonic TC-P50C2 with no power up and no lights of any kind. I found on this forum a similar situation (https://www.badcaps.net/forum/showthread.php?t=40922). When I received the TV it had a blown fuse so I replaced the fuse. No change. I then replaced the power board and still no change ... no power ... no lights. It could be the signal board but I don't want to keep throwing money on this TV without a little more testing. How can I make sure that whatever blew the fuse did not take out many boards with it?

    Here is what I have done lately:
    • Tested the "STBY5V" pin on Power Board connector that goes to Signal Board. Tests 5V.
    • Removed the Signal Board and closely inspected it with a magnifying glass looking for defects. (I know there can be problems I cannot see, but I have spotted a burned chip in the past that saved me lots of time.)


    What would someone suggest next?
    What pictures or additional information can help you help me?

      generally if you have 5v stdby and no LED the A-board is toast. All I could suggest is to download the manual and follow the stdby 5v path.

      pg34, 5v stdby goes to ic4700 at pin 7, that generates stb 3.3 pin8 & stb 1.2v pin 6 .

              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...

              by stecos
              Hi everyone!
              I happened several times, in the search for help from the web, to consult this very interesting forum.
              So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.

              Having said that I come to the gist of my post on the forum as the title suggests.
              For my passion for technology I'm now collecting several...

              LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
              by Hakuu
              Hi There,

              This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

              After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

              More Details

              Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

              Physically bending the T-Con board creates horizontal dotted lines on OLED55CXPUA
              by fredtred
              Hello!
              I have been trying to solve this issue the past 12 months to no avail. I have been a lurker here during that time but finally decided to post my problem and see if anybody knows a solution.

              Problem
              My tv (OLED55CXPUA) has an issue where it displays horizonal lines of dotted artifacts.

              (See Attachment 1)

              Self Diagnosing
              After a very long troubleshooting period I traced the issue to the T-Con board. If I gently flexed/bend the board I could make the display go from GOOD to BAD and vice versa. I have ruled out the connectors/wires...

              (SOLVED) - ONN 100012588 No Power, Then Rebooting After Main Board Change
              by JDC
              ONN 100012588
              Issue: No Power, Then Rebooting After Main Board Change

              Short answer: replace main board and power board
              Technical answer: replace main board and Q306 & Q307 on power board.

              Long answer:

              TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....
