    This monitor is mine if I can repair it. The symptom is excessibe
    brightness with retrace lines. Screen control on the flyback does
    nothing. Voltage at G2 is like 660V or something - I am pretty sure
    this might be too high. All resistors in the G2 circuit seem to be ok,
    and I replaced a high voltage cap as well just in case. Basically the
    crt board (at least the part directly attatched to the tube) checks
    fine.

    Could this be a result of something near the flyback- or the flyback
    itself?
    Has anyone seen a case history on this model?

    As usual, any and all advice is highly appreciated. - Tim

    Yes, look around the flyback for an open resistor, I've seen this a number
    of times on older monitors.
