    I have a KDS VS-7P monitor that was purchased 18 months ago, but I jus
    started using it. Warranty has expired and shipping to KDS for repai
    is way to expensive. Description of problem: Power led comes on. Bu
    the relay does not engage. There is filament. If I unplug th
    degaussing coil relay clicks in, but still no high-voltage. Can anyon
    tell me what voltages should be coming from the power supply? Wha
    should be the voltages on the flyback? Any known issues with the mode
    that may be cause a problem similiar to what I have described

    Check the solder connections under the relay, I have found the same problem
    with 3 KDS over the years. The coil in the relay runs hot and corrupts the
    solder.
    Check the whole board wile your at it.
