Avoid using an excessive amount of cleaner.
Abrasive cleaners, solvents or other harsh chemicals might 
scratch the lens.

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 38 for 
information.
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 soft flat surface, then insert a small 
screwdriver or other flat object into the tab on the lamp mod-
ule door (Figure 20).

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 Security Lock 
The projector has a security connector for use with a PC Guardian 
Cable Lock System (Figure 23). See “Optional Accessories” on 
page 39 for ordering information. Refer to the information that 
came with the lock for instructions on how to use it to secure the 
projector.

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 29.
Make sure that the cables do not have any bent pins.

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

no greater than 1024x768. 
Problem: Image isn’t centered on the screen

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.

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.

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.
