Pre-installation Testing and Troubleshooting

(HSA 200CE and HSA 200SE Models Only)

Before installing an HSA 200 with an Extender line driver into
furniture, test the system to make sure that the connections and
settings are correct.
1. Apply power to the line driver. The power/signal LED on
the line driver will light to indicate that the line driver is
receiving power.
If the LED does not light, check the wiring at both the line
driver 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 the appropriate
(unbalanced or balanced) output signal.
3. If the input is from a laptop computer and no picture
appears, use a laptop breakout cable for the input
connection. 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. 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.
2. 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.
3. If the picture still is not displayed correctly, call the Extron
S3 Sales and Technical Support Hotline.
