Maintenance & Troubleshooting
•
You might need to turn everything off and power up the 
equipment again in the proper order. Refer to your com-
puter ’s documentation to determine the correct order.
•Make sure your laptop’s external video port is turned on. See 
the “Portable and Laptop Activation Chart” on page 41 or 
your computer ’s manual for details.
•Make sure your computer ’s video board is installed and con-
figured correctly.
If you’re using Windows 3.x:
1In the Windows Program Manager, double-click the Win-
dows Setup icon in the Main program group.
2Verify that the Display setting is 1024x768 or less.
If you’re using Windows 95:
1Open “My Computer” icon, the Control Panel folder and 
then the Display icon.
2Click the Settings tab.
3Verify that the Desktop area is set to 1024x768 or less.
 Also check the following: 
•Does your computer have a compatible video board? The pro-
jector isn’t CGA or EGA compatible.
•Is your computer ’s video port activated? This is especially 
true for laptop computers. See “Portable and Laptop Activa-
tion Chart” on page 41.
Problem: Image is too wide or narrow for screen
•You might need to manually adjust the tracking to reduce or 
enlarge the projected image. Refer to “Manual Tracking” on 
page 22.
•Adjust the resolution of your video card if it’s greater than 
1024x768 pixels.

Problem: Image is out of focus
•Turn the projection lens to focus the image.
•Make sure the projection screen is at least 5 feet (1.5 m) from 
the projector.
•Check the projection lens to see if it needs cleaning.
Problem: Image and menus are reversed left to right
•Rear projection mode is probably turned on. Turn Rear Projec-
tion off in the Controls menu. The image should immediately 
return to forward projection. See “Rear Projection” on 
page 24.
Problem: the projector displays vertical lines, “bleeding” or 
spots
•Adjust the brightness. See “Brightness” on page 18.
•Check the projection lens to see if it needs cleaning.
Problem: no sound
•Adjust volume.
•Verify audio/input connections.
•Adjust audio source.
Problem: Image is “noisy” or streaked
Try these steps in this order.
1Deactivate the screen saver on your computer.
2Tu r n  
Auto Image off and then back on again. See “Auto 
Image” on page 21. 
3Adjust the synchronization and tracking manually to find an 
optimal setting. See “Manual Sync” on page 21 and “Manual 
Tracking” on page 22.
•The problem could be with your computer ’s video card. If 
possible, connect a different computer.

Maintenance & Troubleshooting
Problem: Projected colors don’t match the computer or video 
player’s colors
•Just as there are differences in the displays of different moni-
tors, there are often differences between the computer image 
and the projected image. Adjust the brightness, tint and/or 
contrast from the Display menu. See “Brightness” on page 18, 
“Tint” on page 18 and “Contrast” on page 18. 
Problem: Lamp seems to be getting dimmer
•The lamp begins to lose brightness when it has been in use for 
a long time. Replace the lamp as described in “Replacing the 
Projection Lamp” on page 29.
Problem: Lamp shuts off
•A minor power surge may cause the lamp to shut off. Turn the 
projector off, wait at least a minute, then turn it back on.
Before calling Boxlight for assistance, please have the following 
information available:
•the projector ’s serial number (located on the bottom label)
•the resolution of your computer.

Portable and Laptop Activation Chart
Many laptop computers do not automatically turn on their exter-
nal video port when a secondary display device such as a projec-
tor is connected. Activation commands for some laptop 
computers are listed in the following table. (If your computer is 
not listed or the given command does not work, refer to the com-
puter ’s documentation for the appropriate command.) On some 
laptops, the activation function key is labeled with an icon, for 
example   or the text CRT/LCD.
NOTE: Often, pressing the key 
commands once activates the 
external video port, pressing it 
again activates both the external 
and internal ports, and pressing it 
a third time activates the internal 
por t. Refer to your computer’s doc-
umentation for details on your spe-
cific model.
