Lamp operating

error

This can happen when the main power switch at the rear of the

projector was turned off before the cool-down

period had

finished the last time the projector was turned off, and it was then

turned back on again before one hour had passed.

When turning off the projector, wait 2 minutes. After about 2

minutes, the cooling fan will stop. When the cooling fan stops,

turn off the main power switch and then turn it back on again.

When the main power switch is turned back on, the projector will

return to its previous state, so press the [Power] button on either

the remote control or the projector's control panel to turn it back

on. If the lamp operating error happens again when the power is

turned back on, remove the lamp and check if the lamp is broken.

If it is not broken, reinstall it. If it is broken, replace it. Then turn

on the main power switch at the rear of the projector and press

the [Power] button on either the remote control or the projector's

control panel.

If the indicators still show a problem, stop using the projector,

turn off the main power switch, disconnect the power cord from

the electrical outlet, and contact your dealer or the nearest

address provided at “International Warranty Conditions” in

included in the

each problem.

No images appear p.37, p.38 Images appear dark p.41

Poor image quality p.39 Images appear green p.41

Only part of the image is displayed (Large/small) p.40 The remote control does not work p.41

The image colors are not right p.40 The power does not turn off p.42

Condition

No images appear (Nothing at all appears)

Probable cause Remedy

Is the lens cover still attached?

Is the power cord disconnected?

Check the power cable connection at the power inlet of

the projector and at the wall outlet. (p.6)

Is the main power switch turned off?

Turn on the main power switch at the rear of the

projector. (p.6)

Was the power turned off and then straight

back on again?

While the indicator is flashing orange (during cool-

down ), the [Power] button on eiher the remote

control or the projector's control panel will not operate.

Wait until cool-down has finished. You can then use the

[Power] button on either the remote control or the

projector's control panel. (p.8)

Have you pressed the [Power] button on

either the remote control or the projector's

control panel?

Press the [Power] button on either the remote control or

the projector's control panel. (p.7)

Is sleep mode active?

When sleep mode has been set to “ON”, the lamp turns

off automatically if no operations are carried out for a

set period of time while no video signal is being input.

The indicator lights orange at this time.

Turn the projector power back on. To cancel the sleep

mode setting, set "Sleep Mode" in the “Setting” menu

to "OFF".

The image contains interference

Probable cause Remedy

Has the focus been adjusted correctly?

Adjust the focus. (p.13)

Has the front adjustable foot been adjusted

so that the projection angle is too big?

If the projection angle is too big, the image will be out

of focus vertically.

Adjust the projection angle. (p.10)

Is the projector at the correct distance?

The recommended distance from the projector to the

screen is within 0.9 - 13 m (2.9 - 42.6 ft). Set up the

projector so that the projection distance is within this

range. (

Setup Guide

)

Is the projector beam perpendicular to the

screen?

Adjust the projection angle so that the projector beam

is perpendicular to the screen. (p.10)

Is the lens dirty?

Clean the lens. (p.44)

Has condensation formed on the lens?

If the projector is suddenly taken from a cold

environment to a warm environment, condensation may

form on the lens, and this may cause the images to

appear fuzzy.

Turn off the power and wait for the condensation to

disappear.

Does the input signal setting match the

connected source?

Use the “Video Signal”, “Input A” or “Input B”

commands in the “Advanced” menu to select the signal

format that matches the connected source.

“Advanced” - “Video Signal”, “Input A”, “Input B”

(p.29)

Are the cables connected correctly?

Check that all cables that are required for projection are

connected correctly. (

Setup Guide

)

Is an extension cable being used?

If an extension cable is used, electrical interference

may increase.

Use the accessory cables provided, or connect a signal

amplifier and see if this helps.

Have the synchronization , tracking and

display position been adjusted correctly?

(When connected to a computer)

Press the [Auto] button on either the remote control or

the projector's control panel to adjust these settings.

You can also use the environment setting menus to

make the adjustment. (p.16, “Video” - “Tracking” ,

“Sync.” p.27)

Has the correct resolution been selected?

(When connected to a computer)

Set the computer so that the signals that are output are

compatible with this projector. Refer to the

documentation provided with your computer for details

on changing the settings. (p.50)

Troubleshooting

Condition

Images appear dark

Probable cause Remedy

Is the lamp due for replacement?

If the indicator is flashing orange, it means that the

lamp will soon be due for replacement. When the lamp

is nearly due for replacement, the image will become

darker and the tint will become poorer.

Replace the lamp with a new one. (p.46, 47)

Condition

Images appear green

Probable cause Remedy

Do the settings for component video input

signals match the signals from the connected

device?

If the YCbCr or YPbPr settings are incorrect, the

images may appear greenish.

Use the “Input A” or “Input B” commands in the

“Advanced” menu to select the signal format that

matches the connected source.

“Advanced” - “Input A” , “Input B” (p.29)

Condition

The remote control does not work

Probable cause Remedy

Is the remote control being pointed at the

right angle?

The operating angle for the remote control is

approximately 30° horizontally and approximately 30°

vertically. Use the remote control within these ranges.

(

Setup Guide

)

Is the remote control too far from the

projector?

The operating distance for the remote control is

approximately 10 m (30 ft.). Use the remote control

within this distance. (

Setup Guide

)

Is direct sunlight or strong light from

fluorescent lamps shining onto the remote

control light-receiving area?

Avoid using projector in places where the remote

control light-receiving area is exposed to strong light.

Are there batteries in the remote control?

Insert batteries into the remote control. (

Setup Guide
