Troubleshooting and error codes

Problem	Solution
Power can not be turned on.	Check whether the indicators are on or off and how they are lightning.
	POWER STATUS Solution
	Connect the power cord to the projector.
	Plug the power cord into a wall outlet.
No image appears on the screen.	If any objects are blocking the air inlet or outlet grille, remove them and carry out the following. 1. Unplug the power cord from the wall outlet. 2. Make sure that the projector has cooled off. 3. Plug the power cord into the wall outlet. 4. Press the POWER button.
	If any objects are blocking the air inlet or outlet grille, remove them. Don't expose the air outlet grilles to hot air emitted from a heating appliance. Check wheather the filter is clogged with dirt and dust. →Clean the filter, if clogged. (See page 38.)
	After the STATUS indicator stops blinking, press the POWER button. If you unplug the power cord while the fan is rotating, the lamp may not turn on about 1 minute when you plug the power cord next time. The lamp can't turn on again for 1 minute after it goes out. → Press the POWER button several times.
	Replace the lamp. (The lamp is at the end of its life.)
Power turns off.	Attach the lamp cover on the bottom.
Power turns off.	Unplug the power cord from the wall outlet and contact your dealer.
No image appears on the screen.	Cancel the AV mute by pressing the MUTE button.
	Check that the lens cap is removed.
	It may take about 1 minute for the lamp to light up. The lamp fails to light up on rare occasions. In such a case, wait for a few minutes and then try again.
	If the projector was turned off before the lamp was cooled down sufficiently last time, the fan may start rotating and the POWER button may not work after the power cord is plugged. After the fan stops rotating, press the POWER button to turn back on the POWER indicator.
	Set SCART INPUT in the FEATURE menu to OFF. (See page 25.)
	Check that the intake vent is clean. Check that the lamp cover is closed. (See page 37.) Check that the cables connected to the external devices are not broken. When an extension cable is being used, replace it with the supplied cable for check. When images are projected correctly, add an RGB signal amplifier to the extension cable.
	This problem may occur when the intake vent and/or exhaust vents are blocked. (In such a case, the STATUS indicator brinks orange.) → Remove the objects blocking the intake vent and/or exhaust vents and then carry out the following procedure. 1. Wait for the intake fan and/or exhaust fan to stop. (Wait until the STATUS indicator goes out.) 2. Unplug the power cord from the wall outlet. 3. Wait about 10 minutes. 4. Plug the power cord into the wall outlet. 5. Press the POWER button. When the STATUS indicator is steady red, it is indicating that the lamp should be replaced. Replace the lamp in this case. Check that AUTO POWER OFF has been set to OFF. If the lamp has deteriorated, it may go out after a while it illuminates.
The screen for entering the password appears.	PASSWORD FUNCTION in the FEATURE menu has been set to DISPLAY INPUT to enable the password lock. → Enter the password or contact the person in charge of management of the projector. (See page 31.)
"NO SIGNAL" is displayed.	Turn on the power of the connected device, or check whether there is something wrong with the connected device.
	Check whether the external device output signals. (Check this especially when the external device is a notebook computer.)
	Check that the cable connected to the external device isn't defective.
	Check that the projector is connected to the external device using the correct terminals.
	Check that the connected device is correctly selected as the input source.
	When an extension cord is being used, replace it with the supplied cable and check whether images are projected correctly. If images are projected correctly, use an RGB signal amplifier along with the extension cord.
Images are not displayed correctly.	Projected images are shaking.
	Check that the cable connected to the external device isn't intermittent. Connect the cable's plug with the external device's connector firmly.
	Projected images are displaced.
	Press the AUTO POSITION button. Some computers output out-of-spec signals on rare occasion. Adjust the SIGNAL menu. (See page 29.)
	Projected images are distorted.
	Adjust the projector and the screen so that they are perpendicular to each other. (See page 10.)
	Projected images are blurred.
	Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 27.) Replace the lamp. (See page 36.)
	Afterimages persist on the screen.
	This phenomenon is improved by projecting an evenly bright image. (Such "image burn-in" phenomenon where afterimages persist on the screen may occur if a stationary image is kept displayed on the screen for a long time.)
	Red, blue, and green dots appear in projected images.
	This phenomenon is unique to LCD projector and isn't a product malfunction. (A small number of pixels always stay on or off, which are not malfunctions. More than 99.99% of the pixels are effective.)
	Black dots appear in projected images. Fine streaks are seen on projected images.
	This is due to interference with the screen surface and is not a malfunction. Replace the screen or displace the focus a little. Vertical or horizontal streak noise may appear on the projected image, depending on the type of the DVD player or game console you use. In such a case, you can reduce such streak noise by enabling the LPF.
	Projected images become wavy.
	Connect the plugs of the cables to external devices securely. Keep the projector away from devices that emit interfering radio waves. When the keystone adjustment is carried out, the image may not be displayed correctly depending on the type of input signal. This isn't a product malfunction. In this case, readjust the keystone so that the amount of keystone correction is as small as possible.
Hue is not appropriate. Tint in projected images is incorrect. Different color tint.	Check that the cables connected to the external devices are not broken. Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 26.) Check that the cable connected to the external device isn't broken. When comparing images projected by two projectors, tints in the displayed images may be different because of variation between their optical components. This is not a malfunction. When comparing the image projected by this projector with those displayed on the television or PC monitor, tints in the displayed images may be different because of difference in the range of color reproducibility. This is not a malfunction.

Only the motion areas in the images supplied from the computer aren't displayed.	This is caused by the computer being used. Contact the manufacturer of your computer.
	Match the output resolution of your computer with the resolution of the projector. For the method to change the output resolution of the computer, contact the manufacturer of your computer. (See page 43.) Some images and texts appear obscured during the keystone adjustment. In such cases, use the projector without applying the keystone adjustment. (See page 21.)
Others	The exhaust vents emit warm air.
	This air comes out after cooling the inside of the projector. You may feel hot, but this is not a malfunction.
	No audio is output.
	Check that the volume isn't set to low.
	The menu can't be used.
	The microcomputers inside the projector may be wrongly operating because of noise. → Press the POWER button to turn off the lamp and unplug the power cord from the wall outlet. Wait about 10 minutes, plug the power cord in, and try again.
"TEMPERATURE!!" is displayed.	This indication appears when the ambient temperature rises high. When the ambient temperature stays high, the lamp goes out. → Eliminate any causes of the rise in the ambient temperature.
	The � mark appears.	This indication appears when the air inlet or outlet grille is blocked. When they are kept blocked, the lamp goes out. → Remove the objects blocking the air inlet or outlet grille.
	The � mark appears.	This mark appears when ineffective operation is carried out. This isn't a product malfunction.
The remote control doesn't function easily or at all.	Check that the batteries are loaded in the remote control or the batteries are not weak. (See page 6.)
	Check that the remote control sensor isn't exposed to direct sunlight or fluorescent light. (See page 9.)
	Use the remote control within its operation range. (See page 9.)
	Use the remote control at least 10 cm away from the projector.
The buttons on the control panel (except for the POWER button) don't function.	PASSWORD FUNCTION in the FEATURE menu has been set to MENU ACCESS to enable the password lock. → Cancel the password lock or contact the person in charge of management of the projector. (See page 31.)
Abnormal sound is heard.	Because the color wheel spins at a high speed, metallic sounds may be heard in rare occasions. Such symptom is not a malfunction.
If the following problem occurs after the lamp is replaced, check the following first.	The projector does not turn on.
	Fit the lamp cover securely. (See pages 36 and 37.) Reset the lamp operating time. (See page 37.)
	The STATUS indicator blinks.
	Reset the lamp operating time. (See page 37.)
