    Model # 27R430T (YX1), Chassis # ITC008FAR, dead, nothing shorted, or
    leaky, all standby voltages are ok, plug unit in, & just relay click
    for degaussing. No start up, or High Voltage.
    Could the tact switches be leaky? It has a front panel board with the
    IR sensor, & the tact switches on it. Dani.

    You will need to get a bit deeper into the device, checking the voltages at
    the Eprom and MPU to determine if the Data or Clock lines are being loaded
    down. Will definately need a good schematic of the circuit to start tracing
    the associated lines to the other probable devices.
