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. 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.
