This message appears if the electron gun-controlling power
supply unit detects an error during a self test. It is possible
that the error is due to malfunction or equipment error from
isolated noises, in which case shut down the PC, turn off
the Main switch, wait 30 minutes, and then restart the
system. If the problem persists, call a service engineer.
