8. Troubleshooting Guide
We have carefully tested and have found no problems in the supplied
DA1907LX; however, we would like to offer suggestions for the following:
8.1 LED is Not Red
The LED should be ON and RED when power is applied and ON and
GREEN when the unit is receiving power and a SYNC signal.
Cause 1:
There is no AC power.
Solution: Verify the supplied adapter is plugged into a working AC
outlet and that the outlet has power.
Cause 2:
The adapter is not connected.
Solution: Verify the DC power plug coming from the AC adapter is
plugged all the way into the DA1907LX.
Cause 3:
The DA1907LX has a problem.
Solution: If there is AC power to the adapter and the LED still does not
turn on, the DA1907LX or the power adapter may require
service. Please call ALTINEX at (714) 990-2300.
8.2 LED is Not Green
Cause 1:
There is no power.
Solution: Disconnect the video input from the DA1907LX 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.
8.3 No Remote Image
Cause 1:
The source has a problem.
Solution: 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 all the cables are connected properly and that
the continuity and wiring are good. If there is still no image,
call ALTINEX at (714) 990-2300.
8.4 Poor Image Quality
Cause 1:
The source has a problem.
Solution: Check the image on the local monitor and verify the quality is
good. If the local image is good, see Cause 2.
Cause 2
Signal transmission is poor.
Solution: Check the cables for continuity and make sure that
connections are wired properly. If the image is still not correct,
call ALTINEX at (714) 990-2300.
