Possible Solution
• Check to ensure that all devices in the video system
are plugged in and powered on.
• Check the connector on the camera-head cable for
broken pins.
• Detach the camera head from the console and
reconnect.
• Turn off the console, wait 3 seconds, and turn it
back on.
• Release the scope from the coupler and then
reconnect it. Make sure the scope is seated
correctly in the coupler.
• Perform the white-balance test. (See the
"Performing the White-Balance Test" section.)
• Check the settings on video peripherals.
• Ensure the light source has a proper infrared filter
(check with manufacturer specifications).
• Refocus the camera.
• Refocus the coupler.
• Clean and dry both the scope and the coupler
windows.
• Remove the coupler from the camera head and
remove any moisture that has built up between the
two components.
• Rotate the scope. If dust particles in the picture
rotate, the dust is located on the scope itself.
Follow the manufacturer's instructions for cleaning
the eyepiece and negative lens.
• If particles in the picture do not move when you
rotate the scope, the particles are located on the
coupler or camera. Remove the scope and clean
the window on the front of the coupler with a dry
or alcohol-tipped cotton swab.
• If dust particles lie between the coupler and
camera, remove the coupler and clean the coupler
and camera windows.
• Ensure all components are completely dry before
reassembling them, or fogging may result.
