Cleaning the Lens
Follow these steps to clean the projection lens:
1Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
Avoid using an excessive amount of cleaner.
Abrasive cleaners, solvents or other harsh chemicals might 
scratch the lens.
2Lightly wipe the cleaning cloth over the lens.
3If you don’t intend to use the projector immediately, replace 
the lens cap.
Replacing the Projection Lamp
WARNING: To avoid burns, 
allow the projector to cool for at 
least 30 minutes before you open 
the lamp module door. Never 
extract the lamp module while the 
lamp is operating.
The lamp hour counter in the Status menu counts the number of 
hours the lamp has been in use. The projectors use a metal halide 
bulb. These types of bulbs deteriorate over time. Replace the 
lamp when the brightness is no longer acceptable. You can order 
new lamp modules from your Toshiba dealer. See “Accessories” 
on page 37 for information.
Follow these steps to replace the projection lamp:
1Turn off the projector and unplug the power cord. 
2Wait 30 minutes to allow it to cool thoroughly.
3Place the projector on its side, then insert a small screwdriver 
or other flat object into the tabs on the lamp module door (Fig-
ure 19).
4Pull the lamp door up and remove it.

Troubleshooting
Problem: Nothing on projection screen
Make sure that the power cord is properly connected to a fully 
functional AC electrical outlet. Make sure that the power cord 
is also properly connected to the projector.
If the projector is plugged into a power strip, make sure the 
power strip is turned on.
Make sure you have removed the lens cap on the projection 
lens at the front of the projector.
Make sure the projector is switched on.
Check the projector ’s lamp to ensure that it is securely con-
nected in the lamp module. See “Replacing the Projection 
Lamp” on page 27.
Make sure that the cables do not have any bent pins.
Problem: Color or text not being projected
You might need to adjust the brightness up or down until the 
text is visible. Refer to “Brightness” on page 18 for more infor-
mation.
Problem: The screen resolution is not right
Make sure the computer ’s video card is set for a resolution of 
no greater than 1024x768. 
Problem: Image isn’t centered on the screen
Reposition the image. Refer to “Horizontal position” on 
page 22 and “Vertical position” on page 22.
Be sure the projector is at a 90 degree angle to the screen.
Problem: Only the start-up screen displays
Verify that the cables are connected correctly. See page 7 
through page 8 for connection procedures.
Verify that the proper input source is connected. See “Source” 
on page 15.

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 computer ’s external video port is turned on. 
See the “Portable and Computer Activation Chart” on page 39 
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.
Problem: Image is too wide or narrow for screen

enlarge the projected image. Refer to “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 27.
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.
