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.
