    LCD 4 pin external 12v supply pinout

    I received an LCD monitor with out the external power supply called One Monitor
    model PV198SG. The input rating is 12V DC at 4.2 A. It has a 4 pin connector .
    Does anyone have the pinout.

    When I receive a monitor without the four pin external power supply, I will remove the back of the monitor to identify the power and ground pins. And then wire in a compatible voltage and amperage power supply for testing.
    Whatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!

      if you have a multimeter, it's even easier.
      put it in diode test mode (beep mode). one probe into the hole where the VGA/DVI cables would screw into (or any other exposed metal part), and with the other, go through the 4 pins.
      should be 2x ground (beeping) and 2x positive (no beeps or just a short one)

      edit: from a quick google search this seems to be a combo LCD monitor and TV

        Thanks

        It looks like the 2 pins closest to the DC IN are the ground pins and the 2 pins farthest away are the 12V pins.

          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.

          Assuming...

          Modification to a ZD-987 desoldering/soldering station using a external switching power supply
          by sam_sam_sam
          I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

          I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

          Aorus 17G YD laptop, broken display, could not switch to external monitor
          by ArchangelGabriel
          Hello guys! I need a little help, I have one laptop for repair, it is an Aorus 17G YD, gaming laptop. Broken display, some cable ripped form daughter board connector, case broken, battery discharged and probably locked, etc. After I did the most tedious job I ever did on soldering back the broken cables (shielded cable) , I measured resistance on CPU and GPU core, 3 and 5 v ps and any coils I find on the board, everything seems to be fine. After I plugged the charger I don't get the power led light on from the charger connection maybe because the battery is locked , but on power button I have

          How to force Acer Aspire Series to bootup BIOS/UEFI on external Monitor?
          by maralexbar
          I ask this question in general as there are many Acer Aspire models with UEFI Insyde BIOS that do not boot to the BIOS on an external monitor (VGA, HDMI, etc) showing only the Internal LCD (LVDS, eDP etc).
          It's a pain to work on Acer notebooks with a broken screen and not being able to access the BIOS using an external monitor.

          If anyone knows how to force the external monitor as primary for Notebooks of those models

          by penangit
          Hey everyone,hope everyone is fine, I got an issue hoping you guys can help me,

          I got a HP V193 monitor it has a E59670 now i got a few of these, been using them for long time now, however this particular monitor was blacking out for a few times then after unplugging and plugging it back in it gets back to normal until now its dead.

          I tried switching the power supply board with another similar monitor and it works,so I'm trying to fix this power supply board I got some basic in electronics as a hobbyist.

          Steps taken so far:

          Checked all...
