Resolving image issues
Computers, peripherals, source inputs and their connection cables might not be correctly set up to
transmit their signals to your SMART Board interactive whiteboard system. Refer to Video format
compatibility on page 23 and the following section to help resolve these issues.
Loss of signal
If a visual source signal is lost 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.
g To resolve signal loss issues
1. Wait approximately 45 seconds for the image to synchronize. Some video signals require a
longer synchronization period.
2. If the image doesn’t synchronize, check your cable connections to the projector.
3. Ensure that the image signal is compatible with the projector (see Video format compatibility on
page 23).
4. If your projector still doesn’t show a source signal, contact your authorized SMART reseller
( smarttech.com/wheretobuy ).
No projected image
If the projector displays no image at all, and the interactive whiteboard and projector power lights
aren’t on, perform the following procedure.
g To resolve projected image issues
1. Ensure that the power cable is connected to the power outlet.
2. Ensure that your cables are correctly and securely connected as described in the included
SMART Board 480i5 Interactive Whiteboard Systems Installation Guide
( smarttech.com/kb/156695 ).
3. Check the power cable and VGA connector pins to make sure they aren’t bent or broken.
