Compaq Screen issues. Black screen but can see screen momentarily if I hit FN + F4

    I have a Compaq Armada 7400 that I bought from my company after some
    layoffs. I dropped it and broke the screen. I went to the IT guys
    and asked them if they had any bad computers that I could swap screens
    with. They gave me a computer (same kind). I brought it home and
    swapped screens. I booted it up but the screen says black. I went
    back and got another bad computer and swapped screens again. Still a
    black screen. Then I tried with an external monitor and everything is
    great. So I started wondering how I got two bad screens. I then
    tried hitting the Function key and F4 at the same time and the screen
    flashed on for a second. I could see everything perfectly but only
    for about one second. I tried it several times and can see it very
    well and it looks normal but it goes away after one second. I
    attached the computer to the external screen and played with the
    settings but nothing changes.

    I also bought my son a laptop of the same kind and model. His worked
    fine so we swapped hard drives in the event there was a setting or
    driver causing the problem. Still have a black screen that flashes
    when I hit Function +F4.

    Anyone have any suggestions? Sure would like to get this thing
    working properly.

    Thanks Bob

    Have seen this problem. I sounds like your inverter. It is a long
    circuit board that controls the voltage to your LCD. Go to ebay, and
    find one for your model.
