Replacing the lamp

This projector is equipped with 2 lamps to project

images. This lamp is a consumable. It may burn out

or its brightness may decrease during use. In such

cases, replace the lamp with a new one as soon as

possible. Be sure to replace the lamp with a new lamp

separately sold that is exclusive to this projector.

Contact your dealer for purchase of the lamp.

Spare lamp VLT-XD8000LP

Warning:

• Be careful not to drop the lamp ﬁ xing screws into

the inside of the projector. Don’t put a metal piece

or ﬂ ammable object into the projector. Using the

projector with any foreign object present inside

may result in electric shock or ﬁ re. When you can’t

remove the foreign object from the inside, contact

your dealer for removal.

• Be sure to install the lamp securely. When the lamp

isn’t installed properly, it won’t illuminate. Improper

installation may also result in ﬁ re.

• Don’t shake the removed lamp or don’t lift it above

your face. You may be injured in your eye by ﬂ ying

or falling glass fragments.

• Don’t replace the lamp immediately after use

because the lamp cover is very hot. You may get

burned. Turn off the power using the POWER

button. After the lamp goes out, wait about 2

minutes until the intake and exhaust fans for

cooling the lamp stop rotating. Then turn off the

main power switch, unplug the power cord, and

wait at least 1 hour to allow the lamp to cool down

enough to the touch.

• Do not touch the lamp directly. It may break and

cause injury or burn.

Interval of lamp replacement

The recommended interval of lamp replacement is

about 4000 hours

*1*2

of consecutive use. Such interval

differs depending on the operating environment

and may be shorter than 4000 hours

*1*2

. Decrease

in luminescence and/or color brightness indicates

that the lamp needs to be replaced. When the lamp

operation time exceeds 3000 hours

, the indicator

will blink alternately between green and red (while the

lamp is lit; when the lamp is not lit, the indicator will

be lit red only) and the lamp replacement message

will appear on the screen for 1 minute everytime the

lamp is turned on. When the lamp has been used

for about 3800 hours

, the replacement message

(LAMP REPLACEMENT) will appear on the screen for

1 minute every 20 hours

thereafter. When the lamp

operation time exceeds 4000 hours

*1*2

, the projector

automatically shuts off.

*1: Duration when LAMP MODE of the INSTALLATION 1

menu is set to LOW. When it is set to STANDARD, this

duration will be shorted.

*2: When LAMP MODE is set to STANDARD, this duration

will be shorted to 2000 hours.

Caution:

• Don’t remove the lamp for any purpose other than

replacement. Unnecessary removal of the lamp

may result in a breakdown.

• This projector uses a high-pressure mercury lamp

as the light source. The high-pressure mercury

lamp may explode or fail to illuminate permanently

because of an impact, scratch, or deterioration

through use. The period of time until explosion or

permanent failure to illuminate varies considerably

from lamp to lamp, depending on operation

conditions. Therefore, the lamp may explode soon

after the start of use.

• The possibility of explosion of the lamp increases if

you use it beyond its replacement period. When the

instruction of lamp replacement appears, replace it

with a new one immediately even if the lamp is still

lighting normally.

• When the high-pressure mercury lamp explodes,

glass fragments will scatter inside or outside the

lamp box and the gas charged inside the lamp

will diffuse inside or outside the projector. The gas

inside the lamp contains mercury. Be careful not

to breathe it or avoid it from entering your eye or

mouth. If you should breathe it or if it should enter

your eye or mouth, see a doctor immediately.

• In the event that the high-pressure mercury

lamp exploded, glass fragments may have been

scattered inside the projector. Ask your dealer to

replace the lamp and to inspect the inside of the

projector. When you clean or replace the lamp by

yourself, be sure to hold the handle of the lamp.

You may get injured by glass fragments.

• When removing the lamp from the ceiling-mounted

projector, use the lamp replacement tray packed

with the projector or option lamp to prevent glass

fragments from scattering.

• Be sure to use the lamp exclusive to this projector,

VLT-XD8000LP. Use of other lamps may cause a

failure of the projector.

Before replacing the lamp

1. Check which indicator (for LAMP 1 or LAMP 2) is

illuminating or blinking.
