If you reboot the A1200, with 3 key's held down less < 2 Sec, No Video output appears at all & the Monitor reverts to standby mode.
IF A1200 require Powercycle at anytime then PSU must remain off for at least 1 Minute or Indivision fails to Output any display or switch monitor on.
Hope this explains the symptoms.
