8.2 LED IS NOT GREEN
Cause 1: There is no power.
Solution: Disconnect the video input from the DA1957CT 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 1: Verify the computer output is operating correctly by connecting it directly to a local monitor. If the display is good, see Solution 2.
Solution 2: Verify that the transmitter and receiver are each operating correctly by connecting them directly to each other, bypassing the DA1957CT. If the display is good, see Solution 3.
Solution 3: Reconnect the DA1957CT. If the Power/Signal Present LED is on and red with a signal, call ALTINEX at

Cause 1: The source has a problem.
Solution: Check the source and make sure that there is a signal present and all source connections are correct. If the source is working and there is still no sound, see Cause 2.
Cause 2: The volume is too low.
Solution: Increase the Audio Gain on the transmitter toward maximum. If there is still no sound present, see Cause 3.
