Common Problems & Solutions

(→ "Power Indicator"/"Status Indicator"/"Lamp Indicator" on page 182.)

Problem Check These Items

Does not turn on

or shut down

• Check that the power cord is plugged in and that the Power button on the projector cabinet or the remote control

is on. (→ pages 14, 15)

• Ensure that the lamp cover is installed correctly. (→ page 158)

• Check to see if the projector has overheated. If there is insufﬁcient ventilation around the projector or if the room

where you are presenting is particularly warm, move the projector to a cooler location.

• Check to see if you continue to use the projector for another 100 hours after the lamp has reached the end of its

life. If so, replace the lamp. After replacing the lamp, reset the lamp hours used. (→ page 113)

• The lamp may fail to light. Wait a full minute and then turn on the power again.

• Set [FAN MODE] to [HIGH ALTITUDE] when using the projector at altitudes approximately 5500 feet/1700 meters

or higher. Using the projector at altitudes approximately 5500 feet/1700 meters or higher without setting to [HIGH

ALTITUDE] can cause the projector to overheat and the projector could shut down. If this happens, wait a couple

minutes and turn on the projector. (→ page 103)

If you turn on the projector immediately after the lamp is turned off, the fans run without displaying an image for

some time and then the projector will display the image. Wait for a moment.

Will turn off • Ensure that the [OFF TIMER] or [POWER OFF ON NO SIGNAL] is off. (→ page 99, 107)

No picture • Use the Computer 1, the Computer 2, the Video or the S-Video button on the remote control to select your source

(Computer, Video or S-Video). (→ page 17) If there is still no picture, press the button again.

• Ensure your cables are connected properly.

• Use menus to adjust the brightness and contrast. (→ page 91)

• Ensure that the lens cover is open. (→ page 5)

• Reset the settings or adjustments to factory preset levels using the [RESET] in the Menu. (→ page 113)

• Enter your registered keyword if the Security function is enabled. (→ page 33)

• Be sure to connect the projector and notebook PC while the projector is in standby mode and before turning on

the power to the notebook PC.

In most cases the output signal from the notebook PC is not turned on unless connected to the projector before

being powered up.

* If the screen goes blank while using your remote control, it may be the result of the computer’s screen-saver

or power management software.

• See also the next page.

Picture suddenly

becomes dark

• Check if the projector is in the Forced ECO mode because of too high ambient temperature. If this is the case,

lower the room temperature by turning down your air conditioner.

Color tone or hue is

unusual

• Check if an appropriate color is selected in [WALL COLOR MODE]. If so, select an appropriate option. (→ page 98)

• Adjust [TINT] in [PICTURE]. (→ page 91)

Image isn’t square to

the screen

• Reposition the projector to improve its angle to the screen. (→ page 19)

• Use the Keystone correction function to correct the trapezoid distortion. (→ page 24)

Picture is blurred • Adjust the focus. (→ page 21)

• Reposition the projector to improve its angle to the screen. (→ page 19)

• Ensure that the distance between the projector and screen is within the adjustment range of the lens.

(→ page 139)

• Condensation may form on the lens if the projector is cold, brought into a warm place and is then turned on.

Should this happen, let the projector stand until there is no condensation on the lens.

Flicker appears on

screen

• Set [FAN MODE] to other than [HIGH ALTITUDE] mode when using the projector at altitudes approximately 5500

feet/1700 meters or lower. Using the projector at altitudes less than approximately 5500 feet/1700 meters and

setting to [HIGH ALTITUDE] can cause the lamp to overcool, causing the image to ﬂicker. Switch [FAN MODE] to

[AUTO]. (→ page 103)

vertically, horizontally

or both

• Check the computer’s resolution and frequency. Make sure that the resolution you are trying to display is supported
