    Panasonic TC-P Series Vsus Voltage

    I have a TC-P54G20 that I cannot find the proper Vsus voltage. There is no sticker and none of the service manuals show what the proper voltage is. Mine is outputting at 194v. I have read posts that it might have to be 204v. I received the tv broken and the old owner tried to fix it, so who knows if he adjusted it. Can anyone confirm or has anyone got a P series that they can meter the Vsus for me?

    Re: Panasonic TC-P Series Vsus Voltage

    The series for your Panasonic TV is G20, not P.

    A low Vsus can cause:
    - dimmer image (~10% dimmer)
    - dead pixels or pixels sticking
    - pink tint to the image especially in the middle of the display

    It cannot however cause no image unless it were completely missing.

    I would run with it at 194V and see how it goes. It is quite low for a modern plasma TV, I would expect higher, but Panasonic has been among the least consistent manufacturers with regard to their Vsus voltage. Up until late generations their 42" & 46" panels were still hand calibrated with different Vsus for different panels.

      Ah I see. G Series not P. I find at 194v there is green pixels if you are up close to the screen. I was discussing this in another thread with TW. But he didn't know if it should be 204v.

        Green pixels up close: turn down the brightness setting in the user menu until they disappear. Plasmas tend to dither (display noise) especially at low light levels due to bit depth loss at those very low levels.

          Ok. So I should leave the voltage at 194v too? Also, should I set the Vsus level to high in the service menu?

            If you don't notice any of the symptoms I list above leave Vsus as is.

              Panasonic TH-L42D25A checking the PSU output voltage
              by electron_jj
              Hi Everyone, I am new to this forum. I have a Panasonic LED TV which doesnt turn on and is blinking 4 times repeatedly when I turn on the switch. The TV does not respond to the remote control so I had to turn on using the physical switch on the side of the TV. When I turn on the switch the 4 x blinking starts and repeat itself until I turn off the TV. There is a black screen. I turned off the light in the room to check the panel and I think there is no backlight as far as I can tell.

              I have been inspecting and testing the capacitors and diodes in the power supply board to try to...

              Lenovo Yoga 13 Panasonic, no video, fan OK, missing voltage rail (?)
              by jaroslav.psenicka
              Hi all,

              I have a Lenovo Yoga 13 Panasonic here, when powered
              • both fans spins (the sconds starts with a bit of a delay), no image neither on HDMI nor the display
              • most voltage rails seem OK (see image below, red labels)
              • resistnace to ground mostly seem OK as well (blue labels)
              the only suspicious is the 0.0V rail (2nd from left, top row)
              • the resistance to ground is rather low (1.9ohm)
              • when injecting the voltage (1V), it consumes around 200mA, seems OK to me (?)
              also tried new BIOS, no change
              I can't find a schematics for the board - can some of you gurus look at the voltages?...

              Panasonic TC-P60S30 - no standby voltage
              by BobbyMJ
              Hi All,
              Wanting to learn some electronics repair skills.
              I found a non working Panasonic TC-P60S30 and this is my first project / attempt.

              So far I have found a blown cap on the main power supply board.
              After replacing it there's still no standby power.

              Poked around and found a resistor on the PSUB power supply board that measures open.

              An online resistor calculator shows this is a 93k ohm resister.

              My questions:

              Is that correct, 93k ohms?
              Is it a fusible resistor?
              Lastly, how do I know what wattage?...

              by icanic
              Hello ppl!

              Can someone help me where to start with repairing this CRT TV. I have an old vintage PRO series CRT TV from Panasonic, model is TX-C81, cant find any schematics online. I will post pictures with the problems.
              If someone could please tell me where could I start searching to solve the problems and what could be the cause of the problems.
              As you can see all colors are bleeding, it have white glow on black and that white cube is not straight at the top.
              But the main problem for me are the colors and white glow
              ohh and when brightness is a little bit...
