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
(714) 990-2300.
8.3 NO SOUND
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.
Cause 3: Cable connections are incorrect.
Solution: Make sure that cables are properly
connected. Also, make sure that the
continuity and wiring are good. If
there is still no sound, see Cause 4.

Solution: Adjust the Video Equalization on the
DA1957CT. Long cable runs may
require adjustment. In general,
cable runs less then 50 ft (15 m)
require little or no video equalization
and should be set to minimum. If
there is still no image, see Cause 3.

on and green and there is still no
image, call ALTINEX at
