TROUBLESHOOTING

Before asking for repair of the projector, check the followings: If the problem still continues, stop using

it and be sure to unplug the power plug. Then, contact the delivery agent of the projector.

Picture images are not projected on screen.

Phenomenon

Power can not be turned

on.

Picture images are not

projected on screen.

Projected images sud-

denly disappear.

Check/Countermeasure

• Check whether the indicators are on or off and how they are lighting.

• In some cases it takes about one minute to put the lamp on.

• On rare occasions, the lamp fails to come on. Then, turn on the lamp again after a few minutes.

• If the projector finished operation without sufficient cooling, the cooling fan is turning and the follow-

ing operation of the main power button may not work after the main power was turned on. (At this

time POWER indicator blinks in orange.) After the fan has stopped turning, press the power button

again to turn on the indicator in orange.

• Check if the intake vent is not blocked with anything.

• Check to be sure that the lamp cover is closed. (See Page 32 and 33.)

• Check if the cable connecting the projector and external equipment is not broken.

• When an extension cable is used, replace it with the attached cable for checking. If picture images

are normally projected with the attached cable, employ an RGB signal amplifier together with the

extension cable.

• This phenomenon may occur if the intake vent and/or exhaust vent is blocked with any-

thing.

(At this time TEMP (temperature) indicator is lighting in red.)

– After removing those things blocking the intake vent and/or exhaust vent, execute the

followings:

1 Wait until the intake/exhaust fan stops turning. (Wait until TEMP (temperature) indica-

tor comes off.)

2 Turn off the main power switch.

3 Wait about 10 minutes.

4 Turn on the main power switch.

5 Press POWER button.

• LAMP indicator lighting in red indicates that the lamp must be replaced. Replace the

light-source lamp to a new one. (See Page 32 and 33.)
