Monitor occasionally looses sync causing it to go blank for a 
few seconds. 
  This occurs if your electrical power system is very noisy, particularly

The probable cause is that the Local Unit is not powered on.  The 
Local Unit obtains its power from the CPUs Keyboard port, so the 
Keyboard cable must be connected from the Local Unit to the CPU 
even if no Keyboard and Mouse is required, only Video or a 
supplementary power supply can be obtained that connects to the 
Local Units Keyboard connector.
