TROUBLESHOOTING
APPENDIX

Abrasive cleaners, solvents or other harsh chemicals might scratch the lens.
2. Lightly wipe the cleaning cloth over the lens.

CLEANING THE LENS
Before calling Boxlight Corporation for assistance, check the matters below once again.
1. Make sure you have connected the projector to your equipment as described in the section "CONNECTING THE
PROJECTOR" on pages 14 ~ 21.
2. Check cable connections. Verify that all computer, video and power cords are properly connected.
3. Verify that power is switched on.
4. If the projector still does not display an image, re-start the computer.
5. If the image still does not display, unplug the projector from the computer and check the computer monitor's display. The
problem may be with your graphics controller rather than with the projector. (When you reconnect the projector, remember
to turn the computer and monitor off before you power up the projector. Power the equipment back up in order of:
Projector first, and then the computer.)
6. If the problem still exists, check the following chart.
