    touched the screen with a testpen and it lights up....its not static.
    is it monitor or could it be power supply?

    The CRT "Daq" should be grounded. The CRT is coated with a conductive
    material (black material you see from the back) which usualy has a spring
    surrounding the tube. This spring has a wire connected to it. That wire goes
    to the ground (line cord) either directly or through a low value resistance.
    Check continuity from the "Daq" to the ground prong of the line cord. Also
    check the wall receptical for a good ground!
