Common Problems & Solutions (→ “Power/Status/Lamp Indicator” on page 84.)

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 19 and 20)

• Ensure that the lamp cover is installed correctly. (→ page 83)

• 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 79)

• 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 (3000 feet/900 meters on V300X/V300W) 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 70)

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 [AUTO POWER OFF] is off. (→ page 65, 73)

No picture

• Use the COMPUTER1, the VIDEO or the S-VIDEO button on the remote control to select your source (Com-

puter, Video or S-Video). (→ page 22) 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 58)

• Remove the lens cap.

•

Reset the settings or adjustments to factory preset levels using the [RESET] in the Menu. (→ page 79)

• Enter your registered keyword if the Security function is enabled. (→ page 34)

• 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 be-

comes dark

•

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

the internal temperature of the projector by selecting [HIGH] for [FAN MODE]. (→ page 70)

Color tone or hue is

unusual

•

Check if an appropriate color is selected in [WALL COLOR]. If so, select an appropriate option. (→ page 64)

• Adjust [HUE] in [PICTURE]. (→ page 58)

Image isn’t square to the

screen

• Reposition the projector to improve its angle to the screen. (→ page 23)

• Use the Keystone correction function to correct the trapezoid distortion. (→ page 26)

Picture is blurred

• Adjust the focus. (→ page 25)

• Reposition the projector to improve its angle to the screen. (→ page 23)

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

(→ page 11)

• 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 (3000 feet/900 meters on V300X/V300W) or lower. Using the projector at altitudes less

than approximately 5500 feet/1700 meters (3000 feet/900 meters on V300X/V300W) and setting to [HIGH

ALTITUDE] can cause the lamp to overcool, causing the image to ﬂicker. Switch [FAN MODE] to [AUTO]. (→
