6.  TROUBLESHOOTING  

 

a.  No  picture  after  applying  power  –  (i)  check  all  plugs  and  cables  are  securely 

connected  to  the  proper  connectors;  (ii)  ensure  your  power  supply  is  providing  the 
correct voltage and current.  

 

b.  The  picture  has  ripples  –  (i)  check  to  see  if  the  power  supply  is  experiencing  AC 

ripple,  if  so  a  filter  may  be  required;  (ii)  determine  if  the  monitor  is  faulty;  (iii) 
determine  if  other  peripheral  equipment  is  causing  ripple  and  if  so  make  the 
necessary adjustments.  

 

c.  The picture background continuously changes color – a fluorescent lamp’s magnetic 

field  may  cause  color  roll,  therefore,  reduce  the  number  of  fluorescent  lamps  or 
increase the distance between the camera and the lamps.  

 

d.  The picture appears smeared – (i) the power supply voltage level may be unstable, 

therefore,  try  another  power  supply;  (ii)  ensure  the  cables  are  correctly  connected 
and/or the cables are of the correct impedance.  

 

e.  Other interference may require a SecurityTronix ground loop isolation filter.
