Troubleshooting
Before calling your dealer or service center for assistance, check the items below once again.
– Make sure you have properly connected the projector to peripheral equipment as described in “Connecting to Video
Equipment” and “Connecting to a Computer” on pages 15 – 16.
– Make sure all equipment is connected to an AC outlet and the power is turned on.
– When you operate the projector with a computer and it does not project an image, restart the computer.
– Solutions
Problem:
No power.
– Plug the power cord of the projector into an AC outlet.
– See if the automatic slide shutter is only half-open. When it is half-open, the POWER
indicator blinks orange and the projector cannot be turned on (see page 18).
– See if the Main On/Off switch is on.
– Wait 90 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 44).
– Check the projection lamp (see page 49).
– Check if the projector is installed on a flat surface.
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 48).
– 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.
– Projecting from the excessive slant angle to the screen may cause keystone
distortion and partial imperfect focus (see page 14).
No image.
– Check the connection between your computer or video equipment and the projector
(see pages 15 – 16).
– See if the input signal is correctly output from your computer. For some laptop
computers, the setting for the monitor output needs to be changed when
connecting to a projector. See your computer’s instruction manual for the setting.
– It takes about 20 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 24 – 26).
– Select a correct input source once again through Menu operation
(see pages 25 – 26).
– Make sure the temperature is not out of the specified operating temperature (41°F
– 95°F [5°C – 35°C]).
– When “No show” is operating, the image cannot be displayed. Press the NO SHOW
button or any other button on the remote control (see page 23).
– When “Cleaning” is operating, the image cannot be displayed. Press any button on
the top control or on the remote control (see page 42).
