To resolve the unlit projector Power and Service lights issue
1. Check the power source, and then make sure that all cables are connected.
2. Confirm that the projector is connected to an active power outlet.
3. Make sure the pins on the connectors aren’t broken or bent.
4. Connect the power cable, and then turn on the projector.
5. If the previous steps don’t resolve the issue, disconnect the power cable and then contact
your authorized SMART reseller.
Resolving image issues
To resolve common image issues, complete the following tasks:
l
Ensure the computer or other video source is on and set to display a resolution and refresh
rate supported by the projector (see
l
Ensure the video source is properly connected to the projector.
l
Press the Input Select button on the remote control or ECP to switch to the correct video
source.
If these tasks don’t resolve the issue, refer to the following sections for additional troubleshooting
information.
Loss of signal
If a video source signal isn’t detected, if it’s out of range of the projector’s support video modes or
if the signal is being switched to a different device or input, the projector doesn’t show a source
signal and instead displays the SMART logo on a blue screen.
To resolve signal loss issues
1. Wait approximately 45 seconds for the image to synchronize. Some video signals require
more time to synchronize. Cycling through the inputs can also help image synchronization.
2. If the image doesn’t synchronize, check the cable connections to the projector and the ECP.
3. Ensure that the image signal is compatible with the projector (see
4. If there are any extension cables, switch boxes, connection wall plates or other devices in the
video connection from the computer to the projector, temporarily remove them to ensure
they aren’t causing the video signal loss.
5. If the projector still doesn’t show a source signal, contact your authorized SMART reseller.
