Cleaning the remote control
Avoid getting dirt, dust or hand lotion on the remote’s trackball. If 
the trackball gets dirty, it will not work properly. Follow these steps 
to clean the trackball and the remote control.
1.Turn off the projector.
2.Using 2 pointed objects, such as pens, remove the trackball cover. 
Put the pointed ends into the two holes in the trackball cover.
3.Turn the cover counter-clockwise about one-half turn until it 
comes off.
4.Remove the trackball.
5.Wipe the trackball gently with a soft, dry cloth. If necessary, 
dampen the cloth with a mild detergent. Do not use alcohol sol-
vents on the trackball.
6.If necessary, use a cotton swab to clean the inside of the trackball 
mechanism.  Be very careful not to press hard on the rubber 
roller; if it gets out of alignment, the trackball will not work prop-
erly.
7.Replace the trackball.
8.Replace the trackball cover. Turn it clockwise to lock it in place.

Cleaning the fan intake filter
The fan intake filters on the bottom and top of the projector catch 
dust and particles in the air. If a filter becomes clogged, the projector 
will not cool properly and may malfunction. To prevent this, clean the 
filters after every 100 hours of use.
To clean the filter:
1.Turn off the power and unplug the power cable.
2.Remove the filter.
• Carefully place a screwdriver against the indented part of the 
filter and lift.
3.Clean the filter.
• Use a vacuum cleaner set on low power to remove the dust 
and dirt. 
4.Replace the filter.
• First, insert the side with tabs, and then press the other end in 
place.
• If the filter cannot be cleaned or is damaged, contact your In 
Focus dealer for a replacement.

Replacing the projection lamp
If the lamp fails to come on and the lamp monitor on the projector 
lights in red, you must replace the bulb. Be sure to replace it with 
another metal halide lamp.
You can order replacement lamps from In Focus. Refer to “Order 
information” on page 66 for information.
Follow these steps to replace the lamp module.
1.Turn off the projector and unplug the power cord. Allow the 
projector to cool thoroughly.
Allow the LitePro to cool for at least 20 minutes 
before you open the lamp cover! The inside of the 
LitePro can become very hot. Use extreme care.
2.Remove the lamp cover on the bottom of the projector.
• Loosen the two screws with a screwdriver or a coin.
• Pull the lamp cover up to remove it.
3.Pull out the lamp.
• Loosen the two screws holding the lamp in place.
• Pull up on the handle to remove the lamp.

Replacing the fuse
A power surge or spike can blow the power supply fuse and cause 
the LitePro to stop working. If this happens, you’ll need to replace the 
fuse.
Use only the specified power supply fuse. Using a 
different fuse may cause serious damage to the 
LitePro.
The correct fuse for your LitePro is a 6.3A. 250V. T. 5x20 mm fuse.
Follow these steps to replace the fuse.
1.Make sure that the condition that caused the fuse to blow no 
longer exists.
2.Turn off and unplug the projector.
3.Remove the fuse holder, located just below the power cord con-
nector, from the projector.
• Pull out the fuse holder with a screwdriver as shown.

Troubleshooting
Do not open the LitePro case!
Opening the case may cause electric shock! 
Except for the projection lamp, there are no user-
serviceable parts inside. If you are having problems 
with your LitePro, read through this section. Call In 
Focus Technical Support if necessary. They will refer 
you to an In Focus Authorized Service Provider if 
your projector needs repair. 
Before you call for assistance
Before calling your dealer for assistance, follow these steps in this 
order to make sure everything is properly connected.
1.Make sure you have connected the LitePro to your equipment as 
described in section “Setting up the LitePro 580” beginning on 
page 7.
2.Check cable connections. Verify that all computer, video, and 
power cables are properly connected.
3.Verify that all power is switched on.
4.If the LitePro still does not display an image, reboot the com-
puter. 
5.If the image is still bad, unplug the LitePro from the computer 
and check the computer monitor ’s display. The problem may be 
with your graphics controller rather than with the LitePro. (When 
you reconnect the LitePro, remember to turn the computer and 
monitor off before you power up the LitePro. Power the equip-
ment back up in this order: LitePro, monitor, computer.)
6.If the problem still exists, read through the problems and 
solutions in this chapter.
