If the following problem occurs after the lamp is replaced, check the following ﬁrst.

Problem

The projector does not

turn on.

The STATUS indicator

blinks.

Solution

• Fit the lamp cover securely. (See pages 33 and 34.)

• Reset the lamp operating time. (See page 34.)

Images are not displayed correctly. (continued)

Solution

• Some signals may be recognized wrongly as XGA60 signal. In such cases, carry out

the following procedure.

1. Set WXGA in the FEATURE menu to AUTO.

2. Display an image with many characters such as HELP menu.

3. Press the AUTO POSITION button.

If images are still recognized wrongly:

•

Set WXGA in the FEATURE menu manually depending on input signal. (See page 26.)

• The input signal may be an inapplicable signal. Change the signal format of the

computer.

• When WXGA in the FEATURE menu is set to other than OFF, it may take long time to

detect WXGA signal or may cause misclassiﬁcation of signals. In such cases, set it to

OFF.

Problem

Images of WXGA

signal are not

displayed correctly.

It takes abnormally

long time to display

images of signals

other than WXGA, or

the images are not

displayed correctly.

Problem

The exhaust vents

emit warm air.

The menu can’t be

used.

“TEMPERATURE!!” is

displayed.

The mark appears.

The remote control

doesn’t function easily

or at all.

The buttons on the

control panel (except

for the POWER button)

don’t function.

Abnormal sound is

heard.

Solution

• This air comes out after cooling the inside of the projector. You may feel hot, but this is

not a malfunction.

• 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.

• 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.

• 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. Clean the ﬁlter, if clogged.

• 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.

• PASSWORD FUNCTION in the FEATURE menu has been set to MENU ACCESS to en-

able the password lock.



Cancel the password lock or contact the person in charge of management of the

projector. (See page 31.)

• Because the color wheel spins at a high speed, metallic sounds may be heard in rare

occasions. Such symptom is not a malfunction.
