Maintenance

About lamp

The product's light source is a mercury lamp that lights at increased internal pressure. Be sure

to fully understand the following characteristics of the lamp and handle it with extreme care.

• The lamp may burst with a loud noise due to impact or deterioration, or fail to light at

the expiration of its life.

• How long it takes before the lamp bursts or the life expires may vary greatly by lamp.

Some may burst shortly after first use.

• Burst is likely to happen if the lamp is used after the replacement period has elapsed.

• When the lamp bursts, the broken pieces of glass may get inside the product or be

released outside from the openings for ventilation.

• When the lamp bursts, a slight amount of mercury gas enclosed in the lamp along with

glass dust may be released from the openings for ventilation.

Immediately replace the lamp when a sign appears on the screen.

• When the replacement time approaches, a message will appear on the screen.

• The risk of burst will increase if the lamp is continuously used without being replaced.

• Frequently check the used hours and prepare spares when the replacement time

approaches. (Refer to "Status display".

When the lamp is broken

• If glass components, including a lamp and a lens, should break, handle the broken

pieces with care to avoid injury and contact your dealer for repair service.

• In the event of lamp burst, unplug the product from the wall outlet, leave and completely

ventilate the room. Then, thoroughly clean the area around the projector and discard

any edible items placed in that area.

• When the lamp bursts, consult a doctor if glass dust or mercury gas gets into your eyes

or you breathe it.

Lamp replacement

A lamp is consumable supplies. If used for extended periods, images will appear dark, and

the lamp could burn out. This is characteristic of a lamp, and is not malfunction. (The lifetime

of the lamp depends on condition of use.) If this happens, replace it with a new one.

WARNING

• If the projector is mounted on the ceiling, it is recommended to use your Toshiba dealer-

ship when the lamp has to be exchanged.

Uncovering the lamp while the projector is mounted on a ceiling may lead to a danger

of damage from falling pieces of glass if the lamp is broken. Besides, working at high

elevations can also be hazardous. Do not attempt to replace the lamp by yourself.

• When replacing, always use lamp "TLPLW14" (sold separately).

CAUTION

• If you have been using the projector, the lamp will be very hot, and may cause burn

injuries.

Wait for the lamp to cool (for longer than 1 hour) before replacing it.

• If the lamp should break, please handle with care to avoid injury due to broken

pieces and contact your dealer for repair service.
