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 in a circular 
motion.
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. Replace the lamp when the 
brightness is no longer acceptable. You can order new lamp mod-
ules from your Toshiba dealer. See “Accessories” on page 36 for 
information. In the unlikely event of a lamp rupture, please con-
tact your Toshiba dealer.
Follow these steps to replace the projection lamp:
1Turn off the projector by unplugging the power cord. 
2Wait 30 minutes to allow the projector to cool thoroughly.
3Invert the projector on a flat surface, then insert a small screw-
driver or other flat object into the tab on the lamp module 
door (Figure 19).

Maintenance & Troubleshooting
4Pull the lamp door up and remove it.
WARNING: Be extremely careful
when removing the lamp module.
In the unlikely event that the bulb
ruptures, please contact your
Toshiba dealer, as small glass
fragments may be generated. The
lamp module is designed to
contain these fragments, but use
caution when removing the lamp
module.

Removing the lamp door
CAUTION: Never operate the
projector with the lamp door open
or removed. This disrupts the air
flow and causes the projector to
overheat.
5Loosen the two non-removable screws on the outside of the 
module.

the lamp door into the projector and pressing the lamp door 
into place. If the lamp door does not fit properly or bulges out, 
remove the door and re-seat the lamp module.
11Plug in the power cord to turn the projector back on.

Maintenance & Troubleshooting
Replacing the Batteries in the Remote Control
The life of the batteries depends on how often and how long you 
use the remote. Symptoms of low battery charge include erratic 
responses when using the remote and a reduced range of opera-
tion.
Follow these steps to replace the batteries:
1Turn the remote face down in your hand.
2Slide the battery cover off the end of the remote.
3Remove the old batteries and dispose of them in an environ-
mentally proper manner.
4Install two new AAA alkaline batteries. Make sure you install 
each in the correct direction.
5Slide the battery cover back on the remote.
Using the Kensington Lock 
The projector has a Kensington Security Standard connector for 
use with a Kensington MicroSaver Security System (Figure 22). 
See “Optional Accessories” on page 37 for ordering information. 
Refer to the information that came with the Kensington System 
for instructions on how to use it to secure the projector.

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 lamp 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 19 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
Move the projector to reposition the image.
Reposition the image using the software. 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 
(keypad only) or Computer and Video (remote only)” on 
page 16.

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 Computer Activation Chart” on page 38 or 
your computer ’s manual for details.
Make sure your computer ’s video board is installed and con-
figured correctly.
Make sure your computer has a compatible video board. The 
projector isn’t CGA, EGA or SXGA compatible.
If you’re using Windows 98:
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.

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-

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 19, 
“Tint” on page 19 and “Contrast” on page 19. 
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. Unplug 
the projector, wait at least a minute, then plug it back in.
Make sure the vents are not blocked.
