Pre-installation Testing and Troubleshooting

Before installing the interface into the wall or furniture, test the system to verify that the connections and settings are correct.

Apply power to the interface. If an active sync signal is present on the input or if the auto-power feature is disabled, the Power LED on the interface lights to indicate that the interface is receiving power.

If the LED does not light, check the wiring at both the interface and the power supply, and ensure that 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 a balanced or an
	unbalanced stereo output signal.
3.	If input is from a laptop computer and no picture appears,
	check the computer’s user’s guide or contact Extron to
	determine if special commands are required to output
	video to the external video port. Also, many laptops’
	screens shut off after the external video port is activated.
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.	Make sure the correct input and output cables are being
	used and that they are not damaged.
2.	Check the DIP switch settings to make sure the interface is
	putting out the correct sync format.
3.	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 or blooming.
4.	If the picture has a white, ghosted image on the right side
	of the lines/characters, the sharpness may be set to high.
	Use a Tweeker or screwdriver to turn the sharpness control
	counterclockwise.
5.	If the picture is still not displayed correctly, call the Extron
	S3 Sales and Technical Support Hotline.
