I've been maintaining Sun equipment for over a year and have seen a common failure mode for the Hitachi 19" Monochrome monitor. When this failure occurs there is a high pitched squealing coming from the power supply module in the monitor. (No, it is not the flyback transformer.) It is often an intermittant problem which can be temporarily "fixed" by power cycling the monitor. Does anyone here recognize this problem and know the solution? Thanks in advance.
