Maintenance
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 dealership 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 “TLPLW40” (sold separately).
If the lamp other than the specified one is used, it may cause a malfunction or
damage to the unit due to the difference in the connector shape or the lamp rate. •
•
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. •

About lamp
Maintenance
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 replacement message
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”.
p.45 )
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, as they may be contaminated.
If the lamp bursts, consult a doctor if glass dust or mercury gas gets into your eyes or is
inhaled.
