– Solutions
– Plug the power cord of the projector into the AC outlet.
– See if the POWER indicator lights red.
– Wait 90-10 seconds after the projector is turned off to
restart the projector. The projector can be turned on after the
POWER indicator turns red. (See page 19.)
– Check the WARNING indicator. If the WARNING indicator
lights red, the projector cannot be turned on. (See page 51.)
– Check the projection lamp. (See page 54.)

– Provide proper distance between the projector and the
projection screen. (See page 13.)

moisture condensation on the projection lens. If this occurs,
leave the projector off and wait until condensation evaporates.

equipment and the projector. (See pages 15-17.)

For some laptop computers, you may need to change the

the projector. See if the selected system is corresponding to
your computer or video equipment. (See pages 6 and 36.)

operation. (See pages 5, 34 and 35.)
