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 26.

Problem: Lamp shuts off

•

A minor power surge may cause the lamp to shut off. Turn the 

projector off, wait at least 2 minutes, then turn it back on.

Before calling your dealer or In Focus Technical Support for assis-
tance, please have the following information available:

•

the projector’s serial number (located on the bottom label)

•

the resolution of your computer.

Call In Focus Technical Support at 

1-800-799-9911 

between 5 a.m. 

and 5 p.m. PST, Monday through Friday.
