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.
2Push the tab on the battery door toward the top of the remote 
and lift the door off.
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.
5Insert the hooks on the battery door into the remote and press 
the tab to re-install the door.
Using the Security Lock 
NOTE: The lamp cannot be 
removed while the security lock is 
attached.
The projector has a security connector for use with a PC Guardian 
Cable Lock System (Figure 25). See “Optional Accessories” on 
page 37 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 the projector is turned on.
Problem: Projector is running, but nothing appears on projec-
tion screen
Make sure you have removed the lens cap on the projection 
lens at the front of the projector.
Check the projector ’s lamp to ensure that it is securely con-
nected in the lamp module. Make sure the lamp access grill is 
installed. See “Replacing the Projection Lamp” on page 27.
Problem: Only the start-up screen displays
Verify that the cables are connected correctly. See page 7 for 
connection procedures.
Make sure that the cables do not have any bent pins.
Verify that the proper input source is connected. See 
“SOURCE” on page 14.
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 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 or EGA compatible.

You might need to adjust the brightness up or down until the 
text is visible. Refer to “Brightness” on page 17 for more infor-
mation.

Make sure the computer ’s video card is set for a resolution of 
no greater than 1280x1024. 
Problem: Image isn’t centered on the screen
Move the projector to reposition the image.
Reposition the image using the menu. Refer to “Horizontal 
Position” on page 20 and “Vertical Position” on page 20.

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 17, 
“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.

Portable and Laptop Activation Chart
NOTE: Visit our website at
projectors.toshiba..com for the
most current activation chart. It is
located in the Technical Library in

Many laptop computers do not automatically turn on their exter-
nal video port when a projector is connected. Activation com-
mands 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 computer ’s documentation for the appro-
priate command.) On many laptops, the activation function key 
is labeled with an icon, for example   or the text CRT/LCD.
NOTE: Usually, 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
