8. Troubleshooting Guide
We have carefully tested and found no problems in the supplied system; however, we would like to offer suggestions for the following:
Symptom
Resolution
Power LED is Off
1. Make sure the projector power on the wall controller is turned on. The VGA wall panel is only on when the
projector power is on. If a computer video signal is present the LED turns green.
2. If the projector power is on and the Power/Signal Present LED is still off, verify the cables on the rear of the VGA
wall plate are properly installed. The switcher has 2 inputs (A & B) for each VGA wall plate. The "A" connector on
the switcher must be connected to the "A" connector on the VGA wall plate.
No Display on Projector
1. Make sure the projector has power and is turned on.
2. Check the source and make sure there is a signal present. The Power/Signal Present LED on the VGA wall panel is
on and green.
3. Make sure the correct input is selected at the wall controller or at the switcher front panel.
Poor Output Image
1. The source resolution may not be compatible with the projector or other display device. Try other resolutions from
the source.
2. The source and display may not be compatible. Connect the source directly to the input of the projector or other
display device. If the image is poor the devices may be incompatible.
No Sound
1. Make sure the audio cable from the PC is plugged all the way into the jack on the VGA wall panel.
2. Make sure the PC is playing audio and that the audio is turned up to a reasonable level and not muted.
3. Make sure the system is not muted. If it is, the mute key on the wall controller will be on an illuminated red.
4. Turn the volume knob on the controller to the right. If the controller has power the green LED indicators above
the knob will turn on to indicate the new volume level.
