    Hello Guys/Girls

    LCD panel, when I press the BNC/D-SUB on the front panel of the monitor
    I could see the output from the computer for about 3-5 seconds. with
    Perfection.

    However, after that it becomes black as deep space. There is power.


    Any help will be great.

    Thanks

    Bad back light or ballast. Initial light up is ok, then it goes out
    because the ballast is not seeing all the lamps come on ok.
    Needs repaired.

    The ballast or lamps may need to be replaced.

    I've fixed two of these with the same symptoms - blown picofuses on the
    inverters were the culprit.

    I also have an lcd that behaves similiarly. I found that if I reboot a
    few times it will eventually come back on, then that no longer worked.
    This lcd comes with a dedicated pci video controller (which provides
    power) , and its also dual head. There are some dos utilities that
    control turning it lcd only, crt only, and dual, after a few times,
    nolonger worked, I hacked up some dos batch files, that would turn the
    lcd on and off in loop, and eventually it stays on, but seems to
    producing a good amount of heat, and produces a smell, and it takes
    longer and longer. I stopped using it, and bought a new lcd monitor,
    this was used when I got it, but I'm wondering if it's repairable.
