– Solutions
Problem
No power
– Plug the power cord of the projector into the AC outlet.
– See if the POWER indicator lights red.
– Wait until the POWER indicator stops blinking to turn on the
projector again. 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.)
– Unlock the Key lock function. (See page 48.)
Image is out of focus
– Adjust the focus of the projector. (See page 22.)
– Provide proper distance between the projector and the
projection screen. (See page 13.)
– Check the projection lens to see if it needs cleaning. (See
page 53.)
– Moving the projector from a cool to warm place may result in
moisture condensation on the projection lens. If this occurs,
leave the projector off and wait until condensation evaporates.
No image
– Check the connection between your computer or video
equipment and the projector. (See pages 15-17.)
– See if the input signal is correctly output from your computer.
For some laptop computers, you may need to change the
setting for the monitor output when connecting to a projector.
See your computer’s instruction manual for the setting.
– It takes about 30 seconds to display an image after turning on
the projector. See if the selected system is corresponding to
your computer or video equipment. (See pages 26 and 36.)
– Select a correct input source once again through menu
operation. (See pages 25, 34 and 35.)
– Make sure the temperature is not out of the specified
operating temperature (41°F ~ 95°F (5°C ~ 35°C)).
