    Hi There,
    I've recently been given a dual input 19" Dell Trinitron monitor that
    needs repair. I'm wondering if this is a fixable problem and if you
    fine folks can advise me on how to fix it myself. I have generally
    good electronic repair skills but have never tackled a monitor before.

    Here are the problems I'm seeing:

    ***The black level is very grey, but dos screens (white text on black)
    are quite legible and clean despite the greyed black background.

    ***Different colors seem to have a smudge running to their right, the
    brighter the color, the darker the smudge and vice versa.

    ***The more white there is on the screen, the darker it gets. The more
    black there is on the screen, the lighter it gets.

    What do you think?
    Thanks,
    Mike

    Sorry, it's actually a 21" P1110.

    Most likely to be caused by problems in the high voltage area. The HV is
    varying with intensity of the image.
    It's very fixable. My first suggestion would be to look into the tripler
    module.

    Don't worry, probably very simple.Two solutions:

    a)

    With this program you can fix the G2 level, that is probably too high.
    Fix it to 125.
    Good work! :)
