    I have a slight problem with my Barco Graphics 800.:(:(

    If the top of the image being displayed happens to be white the projector emits a strange sound and lines appear to cross the top of the screen. This only happens when the image at the top of the screen is white or extreamy light. (My brightness settings are at 50%)

    The source is Svideo and the sound is coming from the rear right if the picture is in front. (The projector is table mounted at the moment). It sounds like the power supply area.


    Has anyone had any experience with this and is there a cure?


    Many thanks for any help

    The 800 series did this from new but it does get worse with age.

    Sounds like the Quadrupler is qetting a bit old does the noise reduce with a reduction in brightness and contrast.?

    The cure is a replacement as these are sealed units.

    Thanks for that.

    The noise does go down slightly when the brightness is reduced.

    The noise does not bug me that much; it's the lines across the screen that worries me. The lines take up about 1 quarter of the screen and are really noticeable on the white background.

    Any idea how much a Quadrupler would cost?

    many thanks
