8.2  LED IS NOT GREEN
Cause 1:
There is no power.
Solution:
Disconnect the video input from the 
DA1907SX and verify the LED is ON 
and RED indicating power is 
present. Reconnect the computer's 
video output. If the LED is still not 
GREEN see Cause 2.
Cause 2:
There is no Sync signal.
Solution:
Verify the computer output is 
operating correctly by connecting it 
directly to a local monitor. If the 
display is good, call ALTINEX at 
(714) 990-2300.

Check the image on a local monitor 
and verify the quality is good. If the 
local image is good, see Cause 2.
Cause 2:
Cable connections are incorrect.
Solution:
Make sure that cables are 
connected properly. Also, make sure 
that the continuity and wiring are 
good. If there is still no image 
present, see Cause 3. If the display

level.
