No Video But All Functions Work
What to check.
1.
Iris adjustment from controller.
2.
RS422 board.
3.
Clock spring ribbon cable.
4.
Voltages/zoom, focus, and iris
functions.
What to do.
Open the iris and verify that video is present.
Check for the presence of video out of the
RS422 board. If video is coming out of the
RS422 board, check the J-Box, composite/
video cable and monitors for the problem.
If video is not coming from the RS422 board,
check for visual damage to the ribbon cables
and verify that the iris is operating.
Ensure that the clock spring ribbon cable is
correctly connected to the camera lens
board.
If voltages are not present and/or the zoom,
focus, and iris functions are not working,
replace the camera/lens board.
If replacing the camera/lens board does not
solve the problem, replace the camera.
