Troubleshooting
Turn on the input devices (computer, audio device) and output device(s) (projector, monitors,
speakers). The image should now appear on the screen, and sound should be audible.
If the Image Does Not Appear or There is No Sound
1. Ensure that all devices are plugged in.
2. Make sure that each device is receiving power. The front panel LED lights green if the
interface is receiving power.
3. Check the cabling and the audio connector wiring and grounding, and make
adjustments as needed.
4. For digital display devices (including LCD, DLP and plasma devices), try turning DDSP on
or off using the front panel DIP switch.
5. To test the system setup and output, substitute a video test generator for the computer
input. Unplug the power cords of the input/output devices and the remote interface,
replace the video source with a VTG, then reconnect the power cords to restore AC
power.
6. Call the Extron S 3 Sales & Technical Support Hotline if needed.
If the Image is Not Displayed Correctly
1. If the output image looks too green, the sync on green (SOG) DIP switch may be set to
On, and the display device may not be configured to handle SOG signals. Set SOG to
Off.
2. If the picture bends or flags at the top of the screen, set the serration pulse DIP switch to
Off.
3. For a display device that experiences intermittent glitches, try turning DDSP on or off
using the front panel DIP switch.
4. If the picture “hangs off” the left or right edge of the screen, and an RGB 580xi S AAP,
RGB 580xi CCS AAP, RGB 580xi SI AAP, or RGB 580xi CCSI AAP device is connected
to the interface, adjust the horizontal shift (H. Shift) control of the AAP to center the
image.
5. If the edges of the image seem to exceed their boundaries or if thin lines and sharp
edges look thick and fuzzy, try changing the Peaking control setting. If the image is too
bright or dark, try changing the Level control setting.
6. If the image still does not display correctly, call the Extron S 3 Sales & Technical Support
Hotline.
