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.
Cause 4:
The receiving device is bad.
Solution:
Make sure the receiving device has 
power and is turned on. If there is 
still no sound, please call ALTINEX
at (714) 990-2300.
8.4 NO REMOTE IMAGE
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:
Video equalization is required.
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.
Cause 3:
There is no signal.
Solution:
If the Power/Signal Present LED is 
on and green and there is still no 
image, call ALTINEX
at
(714) 990-2300.

and verify the quality is good. If the 
local image is good, see Cause 2.
Cause 2:
Video equalization is required.
Solution:
Adjust the Video Equalization on the 
DA1957CT. If the image is still not 
correct, call ALTINEX at 
(714) 990-2300.
