Testing and troubleshooting
1.
Apply power to the line driver. The power/signal LED on
the line driver lights amber (power) or green (video input).
2.
If the LED does not light, check the wiring at both the line
driver and the power supply, and make sure the power
supply is connected to a power source.
If the image does not appear or there is no sound
1.
Make sure that all the devices are powered on.
2.
Ensure that the connectors are wired correctly at both
ends of the cables. Audio cables must be wired for an
unbalanced stereo input signal and for the appropriate
(unbalanced or balanced) output signal.
3.
Check the video source's user's guide or contact Extron to
determine if there are special requirements to output video
to the external video port.
4.
Call the Extron S3 Sales and Technical Support Hotline if
the image still does not appear or there is no sound.
If the image is not displayed correctly
1.
If the picture is too bright or too dark, or if the edges of the
image seem to exceed their boundaries, or if thin lines and
sharp edges look thick and fuzzy, change the gain setting.
If the picture appears and is stable, but it has ghosting
or blooming, verify that the video input is properly
terminated. If the problem is not resolved by changing the
termination, try using a different input cable. Poor quality
or damaged cable can cause ghosting and blooming.
2.
If the picture still is not displayed correctly, call the Extron
S3 Sales and Technical Support Hotline.
