I found an IBM monitor model 6547-00N (chassis CM-1317). I cannot get the
unit to start up. It has a relay that keeps clicking on-and-off but there is
NO VIDEO. The monitor appearently suffered from a fall but there are no
visible cracks in the PCB. The monitor has a feature that causes it to
de-guass automatically upon power-up and I suspect that the relay that's
going on and off has something to do with the de-guass routine. Has anyone
ever seen such a problem? My next step is to try and locate a schematic for
this monitor so I can check test-point voltages and begin tracing the
relay's power supply.
