    Panasonic WV-LW2200/G, need dump file.

    Hi everyone, i need dump file from monitors Panasonic WV-LW2200/G , board TNP4CLM0805 REV:2 22GM05T0038. After plug power LED on but not screen, capacitors on power module seem to by ok, but I replaced it anyway without success.
    Sometimes "no signal" will appear for a while.
    Maybe the file replacement will help.
    Greetings to all.

    I doubt very much what you are asking for will solve your issue. I think you may have a PSU and/or Backlight issue that would need tearing down the Monitor and taking some test voltages for us.

      Thank You for your answer.
      Backlight ok. I will check the power module again tomorrow again.

        You may have to place your DMM on the pin connector before turn on so that at turn on you can observe the voltages and note the change at shut down. You may have to do this several times for the various pins or perhaps is you post clear pics of the boards and connectors I may be able to help you more.

          When power up, voltage power line 12V up 20-25V , this same moment line 5V down to 4,65V, after moment voltage ok. (sorry my bad english) (Belgium 3 - Japan 2, I ) Sometimes on lcd "no signal".
          I can not find schematics or service manuals this monitor.

            Let me think about this some more. You may in-fact have a BIOS issue.
