    Panasonic 50" Plasma and its crazy Stand by voltage...

    Hello folks,

    So, my TC-P50V10 has a 1 blink code. I checked the voltage of the stand by .. supposed to be 5v and it is 7.44 both on the a board and the power board. A25 and P25 pin 9. What does this mean? I read that if there is 5v voltage it is the A board.. but what if it is more.. same thing? replace the A board?

      Did you use DC volts or AC volts on your meter?
      (You must use DC volts...)

                  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...

                  Vizio E400i-B2 missing stand-by voltage
                  by DXseekerMO
                  I picked up this Vizio E400i-B2 with no stand-by light and diagnosed it with missing stand-by voltage. I found a Power Supply at ShopJimmy, installed it but it didn't work properly. SJ refunded the transaction and did not ask me to send the board back.

                  So I took some voltage readings upon the original board. Here's what I found:

                  Main caps have 169.9v

                  AC detect voltage is 1.3v

                  None of the MOSFETS appear to be short.

                  The opto (IC106) that appears to have something to do with stand-by voltage has 3.0 volts on terminal 1...

                  Panasonic plasma TX-P42ST50 - 6 blinks
                  by jm1234
                  Hi,
                  anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
                  It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
                  I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
                  I checked that board for any obvious faults...

                  Panasonic Plasma main board repair (ST30 GT30 VT30 ST50 GT50 VT50),LED with 3 blincks
                  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...

                  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?...
