Maintenance
CAUTION
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 continues to be 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 possible 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.

Lamp replacement
A lamp is a consumable item. 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 strongly recommended that you
contact a Toshiba dealer when the lamp has to be exchanged. Do not attempt
to replace the lamp by yourself.
If you uncover the lamp while the projector is mounted on a ceiling, there may be
a danger of damage from falling pieces of glass if the lamp is broken, resulting
in possible injury. In addition, working at high elevations can also be potentially
hazardous. Do not attempt to replace the lamp by yourself.
Always use lamp “TLPLW15” (sold separately) when replacing the lamp.
Using a lamp other than the one specified 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 1 hour or longer for the lamp to cool 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.
