•
Make sure that the power cord is properly connected to a fully
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.

tion screen
•
Make sure you have removed the lens cap on the projection
lens at the front of the projector.

The lamp automatically shuts off at 2,050 hours and the LED
blinks orange. See “Replacing the Projection Lamp” on

Check the projector’s lamp to ensure that it is securely con-
nected in the lamp module. Make sure the lamp door is
installed. See “Replacing the Projection Lamp” on page 33.

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 44 or
your computer’s manual for details.
