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 on pages15-17.

–Make sure all equipment is connected to 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.

Problem	– Solutions
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 Temp.indicator. If the WARNING Temp.
	indicator lights red, the projector cannot be turned on. (See
	page 52.)
	– Check the projection lamp. (See page 55.)
	– Unlock the Key lock function. (See page 49.)
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 54.)

	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 37.)
	– Select a correct input source once again through menu
	operation. (See pages 25, 35 and 36.)
	– Make sure the temperature is not out of the specified
	operating temperature (41°F ~ 95°F (5°C ~ 35°C)).
Image is Left/Right reversed	– Check the Ceiling/Rear function. (See page 46.)
Image is Top/Bottom reversed	– Check the Ceiling function. (See page 46.)
