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

Problem Solution

The exhaust vents emit warm

air.

• This air comes out after cooling the inside of the projector. It may feel hot, but this is not a malfunction.

The menu can not be used. • The microcomputers inside the projector may be wrongly operating because of noise.

➜Press the STANDBY/ON button to turn off the lamp and unplug the power cable from the wall outlet.

Wait about 10 minutes, plug the power cable 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.

• This indication appears when the air intake or exhaust vent is blocked. When they are kept blocked, the

lamp goes out.

➜Remove the objects blocking the air intake or exhaust vent.

The mark appears.

• This mark appears when ineffective operation is carried out. This is not a product malfunction.

The remote control does not

function easily or at all.

• Check that the battery is loaded in the remote control or the battery is not weak (see page 4).

• Check that the remote control sensor is not exposed to direct sunlight or fluorescent light.

• Use the remote control within its operation range (see page 7).

• Use the remote control at least 10 cm away from the projector.

Abnormal sound is heard. • Because the color wheel spins at a high speed, metallic sounds may be heard in rare occasions.

Problem Solution

The projector does not turn

on.

• Fit the lamp cover securely (see page 33).

• Reset the lamp operating time (see page 33).

The STATUS indicator

blinks.

• Reset the lamp operating time (see page 33).
