    Emerson PL-P42W-10A plasma

    It will just click on and off twice then nothing. Most voltage reading I only get when it's clicking then gone except standby.
    CN801
    PS On 3.2
    STBY 5.28
    GND 0
    D15v 15.4
    GND 0
    GND 0
    D5.3 5.26
    D5.3. 5.26
    GND 0
    D15v 15.4
    D15v 15.4

    Again only while clicking on do I get correct voltages.

    CN802
    D5.3v. 5.3
    D5.3v. 5.3
    GND 0
    GND 0
    Ps on 3.2
    Vs on 3.2

    CN803
    Not sure if this says V5 or VS
    V5 17-18 range
    V5 17-18 range
    GND 0
    GND 0
    D15v 15

    CN804
    VA 22
    GND 0
    D15 15
    GND 0
    Vs or V5 around 18
    Vs or V5 around 18

    I have replaced power board, the small green board and swap eprom on connection board. I have also have unplugged each board and powered on but to no avail.

    That will be Vs, there is a sticker on the panel with the correct voltage, It looks like the Vs should be 205Vdc, and the Va 55Vdc
    I suspect you have a problem on either the Y-sus or Z-sus boards

      So should I be able to unplug one or the other and it should stay on?

        Yes you can disconnect the y & z boards, and monitor the voltage on the Vs of the power supply to see if it comes up to 205v.

          Emerson plasma PL-P42W-10A clicking no startup
          by Hornnumb2
          Emerson plasma clicks about 4 times but won't start up. I have replaced the power board with a shop jimmy one with no change. I have tried unplugging various board with no change. I do get a green light on t con while it's trying to start but clicks off when power board does. What is my next step?...

          by ArMaaN376
          Hello,
          I am having Samsung PS51E550 Plasma TV. While the TV was working, a crackling sound heard & video went off with audio still ON. After switching it off & ON, the red LED on TV blinks six times & then off.
          Opened TV cover & observed foll
          a) Green LED on the small PCB blinks at @5-6sec ON & off for 3-4 secs. Red LED on logic board ON
          b)Vs & Va on power supply board raises momentarily to 209v & 58v resp & then drops.
          c) Cold test on Y-main board shows all 3 pins of FGPF4536 IGBT short to Grnd.
          How to confirm Y -Buffer board...

          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...

          Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
          by KYBOSH
          Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
          No picture but you hear the TV static (white noise) playing loud and clear.
          The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
          But it seems they didn't get too far and just left it.

          When I first took a look I was amazed at how pristine the inside looked.
          Its as if the TV had been in a time capsule.
          Caps looked like they were just pulled off the self.
          Copper coils had no sign of corrosion on...
