    PANASONIC TC-P50G20 - New issue after replacing SC board

    Hi guys,

    Original problem was TV would not turn back on after I heard a pop and it shut off (this was months ago). I forget the exact blink code but from my searches I traced it to most likely be a bad SC board.

    Ordered one up from EBAY, received it and then got busy and fast forward a few months to today, installed it.

    Great news is the TV now turns on! Huzzah I thought, everything works good, started watching a show to test, found one thin blue vertical line down the screen (see attached).

    Wondering if this could be a new different fault of the replacement board I received or something else I am overlooking.

    -TV did not have this line before original problem.
    -After discovering it I re-seated and used compressed air to clean the connections for SC board as well as the ribbons for the C boards along the bottom.

      usually it's a panel fault, bad luck it coincided with the SC failure. You could go into the service menu (mirror) and do a horizontal flip , if the line stays put, then either panel or the c buffer for that section but history has shown it to be panel.

          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

          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 Soulzink
          Hi everyone,

          I am trying to fix a samsung washinmachine power supply main board.
          I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
          Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
          The power supply board reference is the following: DC41-00189a
          I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel...

          TCL 55RP620K power board issue
          by notallbad
          Originally the tv arrived with dimmed backlights (not failed leds) but everything else worked ok. Adjusting backlight in menu did nothing but voltage changed on dimming control pins,
          0% p_dim at 1.65v and a_dim at 1v
          50% p_dim at 3.3v and a_dim at 1.65v
          100% p_dim at 3.3v and a_dim at 2.88v

          Changed backlight leds anyway as always like to have complete peace of mind they wont fail shortly after selling the tv. No change as expected!

          Leds are 2 rows of 15 6v leds.

          On inspection of the power board found diode MBR3200 shorted so replaced with...

          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...
