LEDs
The Lamp LED on top of the projector (Figure 13 on page 18) will
alert you to certain problems.
•
A solid red Lamp LED means it is time to change the lamp.
See page 30.
•
A blinking red Lamp LED means the projector is overheat-
ing. Turn off the projector and allow it to cool.
The other LED on top of the projector indicates the normal oper-
ating state of the projector.
•
A solid green LED means the projector is on.
•
A blinking green LED means the projector does not recog-
nize an active source or is in DPMS mode. See page 24.
•
A blinking orange LED means the projector is going into
DPMS mode; a solid orange LED means the projector is in
standby or DPMS mode. See page 24 for details.
Problem: The projector is not running
•
Make sure that the power cord is properly connected to a func-
tional 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. Verify that the LED is
solid green.

Make sure you have removed the lens cap on the projection

Check the projector’s lamp housing to ensure that it is securely
connected to the bottom case. See “Replacing the Projection
Lamp” on page 30.
