LAMP 1 / LAMP 2: The condition of each lamp is indicated.			POSSIBLE SOLUTION
Normal condition	Blinking green		When the lamp is illuminating, it is in the warmup mode. (You cannot turn off the power.)			Replace the light source lamp indicated by the illuminating or blinking indicator.
	Steady green		When the lamp is off, it is in the cooling mode. (You cannot turn on the power.) The lamp is illuminating.			Change with a new lamp if this problem recurs.
Replacement	Blinking red		Lamp operation time warning. (Total lamp operation time reached 3000 hours*3.)
	Blinking green/red		Lamp operation time warning. (Total lamp operation time reached 4000 hours34.)			When both indicators blink, wait until the indicators stop blinking and then press the POWER button. If the light source lamps don't illuminate even after you perform the above operation several times, unplug the power cord from the wall outlet and contact your dealer.
Abnormal condition	Steady red		The protection circuit is working or the lamp is in an abnormal condition.			To illuminate the failed lamp again when either indicator blinks, turn off the power and wait until the indicator stops blinking and then press the POWER button. If the light source lamp doesn't illuminate even after you perform the above operation several times, unplug the power cord from the wall outlet and contact your dealer.
	Blinking orange		In the case that LAMP SELECT is set to DUAL, only the normal lamp illuminates (the intensity of one lamp is obtained). In the case that LAMP SELECT is set to SINGLE, LAMP 1, or LAMP 2, only the normal lamp illuminates (the lamp isn't switched).
No image appears on the screen.	Press the BLANK button to cancel BLANK.
	Check that the lens cap is removed.
	It may take about 2 minutes 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 main power switch is turned on. 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 37.)
	Check that the intake vent is clean. 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 displayed correctly, add an RGB signal amplifier to the extension cable.
Power turns off.	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. Turn off the main power switch. 3. Wait about 10 minutes. 4. Turn on the main power switch. 5. Press the POWER button.
	When the LAMP indicator is steady red, it is indicating that the lamp should be replaced. Replace the lamp that is being indicated by the indicator.
	Check that AUTO POWER OFF has been set to OFF.
	If the lamp has deteriorated, it may go out after a while it illuminates.
Images are not displayed correctly.	"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 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.
	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. → Project an image containing many characters such as a help menu and press the AUTO POSITION button. Some computers output out-of-spec signals on rare occasion. Adjust the SIGNAL menu. (See pages 45 and 46.)
	Projected images are distorted. → Check whether there is a wind that blows the exhausted air from the projector to the direction of the projection lens. Adjust the projector and the screen so that they are perpendicular to each other. (See page 14.)
	Projected images are dark. → Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 42.) Replace the lamp. (See page 62.)
	Projected images are blurred. → Adjust the focus. (See page 12.) Clean the lens. Press the ◀ or ▶ button on the remote control to eliminate flicker. Adjust TRACKING and FINE SYNC. in the SIGNAL menu. (See page 46.)
	White dots are seen on projected images. Black dots are seen on projected images. → Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 42.) Adjust the projector and the screen so that they are perpendicular to each other. (See page 14.)
	Rainbow effect is seen on projected images. → This symptom is normal for a DLP™™ projector and is not a malfunction. (A very small number of pixels may stay lit or out, but such symptom is not a malfunction. Pixels of 99.99% or more are effective.)
	Fine streaks are seen on projected images. → This is due to color breaking noise that occurs in a DLP™™ system and is not a malfunction.
	Projected images become wavy. → This is due to interference with the screen surface and is not a malfunction. Replace the screen or displace the focus a little.
	Hue is not appropriate. → 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. 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. Check that the cables connected to the external devices are not broken.
	Tint in projected images is incorrect. → Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 39.) Check that the cable connected to the external device isn't broken.
	Different color tint. → 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.
	Projected images are obscured. → 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 73.) Some images and texts appear obscured during the keystone adjustment. In such cases, use the projector without applying the keystone adjustment. (See page 14.) When SUPER RESOLUTION is ON, the displayed image may be obscured. Set it to OFF. (See page 44.)
	Noise appears around the image. → In some images such as DVD, noise may appear around the recorded image. In this case, decrease the setting value of OVER SCAN of the SIGNAL menu. (See page 39.)
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.
	The menu can't be used.	The microcomputers inside the projector may be wrongly operating because of noise. → Turn off the main power, wait about 10 minutes, and turn on the main power 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 remote control doesn't function easily or at all.	This mark appears when ineffective operation is carried out. This isn't a product malfunction. • 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. • Check that the CONTROLLER ID matches with the PROJECTOR ID. (See pages 10 and 60.) • Check that the projector isn't controlled by a control panel or other device that is connected to the REMOTE 1 IN terminal. (See page 61.) • When the terminal cover is attached, remote control may not work properly from behind the projector. → Remove the terminal cover.
	The buttons on the projector (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 56.) Check that the projector isn't controlled by a control panel or other device that is connected to the REMOTE 1 IN terminal. (See page 61.)
	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.
Others (continued)	FOCUS/ZOOM doesn't work. Lens shift doesn't work.	Check that LENS LOCK in the INSTALLATION 1 menu isn't ON. (See page 34.)
Others (continued)	If the following problem occurs after the lamp is replaced, check the following first.	Problem
	The projector does not turn on.	Fit the lamp cover securely. (See pages 62 and 63.)
	The LAMP indicator illuminates red.	Reset the lamp operating time of the newly installed lamp. (See page 63.)
