Loss of signal

If a video source signal is not detected, out of range of the
projector's support video modes or 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 a
longer synchronization period, cycling back through inputs to the one you want also helps 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 Video format compatibility on
page 75).
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 your projector still doesn't show a source signal, contact your authorized SMART reseller.
