    If it is ONE LED, how can it be two colors at once?

    When you power off the LCD, and plug it in? Does it go green first?

    The sequence and timing of makes a huge difference on what to look troubleshoot next. That is why this question is so specific.

      As soon as I plug in the Power supply. the ONE dual color LED lights up both colors at once. I tried to take a picture of the LED, but it does not show up, it washes out and you can't tell both colors are lit. You can see at the base of the LED that both colors are lit at the same time in person...you'll have to trust me on this one.......
      They never change to one or the other and they stay on till I unplug it.

      Also, my laptop "detects" it with plug and play beep.

      The logic board is putting out 11.3 vdc to the inverter board, have 2 inverters since I have 2 monitors and neither seem to make a difference.

          Ther is a simple explanation for this. There appears to be two 'processors' on the logic card. One handles the interaction with the front panel, backlights, and also turns on the power to the LCD panel. The other handles the video signal. The first one is defective, and is cycling the power LED at a high rate.

          For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

          Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

            So, does anyone have any other ideas on what to test next? I'm going to start on the other board I think...maybe I'll have better luck.... Can anyone suggest a cross reference for the mosfet listed above? I can't find them at digikey, mouser, jameco, or on google searches???

                No, put it on the back burner. Now it will most likely end up in the trash. I don't even remember what the last thing was I tried.

                  I suggest posting your monitor on your local craiglist/kijiji to give away as others may be able to use parts.
