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 a Computer" and “Connecting to Video Equipment” on page17-19.

Make sure all equipment is connected to AC outlet and the power is turned on.

If the projector does not project an image being operated with a computer, restart the computer.

Problem:

– Solutions

 

 

No power

– Plug the power cord of the projector into the AC outlet.

 

– See if the POWER indicator lights red.

 

– Wait 90-120 seconds after the projector is turned OFF when turning the

 

projector back on. The projector can be turned on after the POWER

 

indicator turns red. (See “Turning Off the Projector” on page 21.)

 

– Check the WARNING indicator. If the WARNING indicator lights red, the

 

projector cannot be turned on. (See "Warning Indicator" on page 47.)

 

– Check the projection lamp. (See page 50 and 51.)

 

– Unlock Key lock for the projector in the Setting Menu. (See page 45.)

Image is out of focus.

Adjust focus of the projector. (See page 24.)

Provide proper distance between the projector and the projection screen. (See page 15.)

Check the projection lens to see if it needs cleaning. (See page 49.)

Moving the projector from a cool to a warm place may result in moisture condensation on the projection lens. In such cases, leave the projector OFF and wait until condensation disappears.

No image

– Check the connection between your computer or video equipment

 

 

and the projector. (See page 17–19)

 

– See if the input signal is correctly output from your computer. Some

 

 

laptop computers may need to change the setting for 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 with your computer or video

 

 

equipment. (See page 27 and 36)

 

– Select correct input source once again through menu operation.

 

 

(See page 26, 34 and 35)

 

– Make sure the temperature is not out of the specified Operating

 

 

Temperature (5°C ~ 35°C).

 

 

Image is Left/Right reversed.

– Check the Ceiling / Rear item. (See “Setting” on page 43.)

image is Top/Bottom reversed.

– Check the Ceiling item. (See “Setting” on page 43.)
