Replacing the lamps
When a lamp reaches the end of it's usable life, the following message is displayed.
Replace the lamp.
The projection lamps should be replaced when they burn out. They should only be replaced
with a specified replacement part, contact your local dealer if unsure.
CAUTION:
•
The lamp contains a certain amount of mercury and should be disposed of according to
local ordinance regulations.
•
Avoid touching the glass surface of the new lamp: doing so may shorten its operation
life.
•
If the lamp's useful life ends and projector could not turn on over 2100 hours, please
have the projector serviced.
Notes
•
The lamps are positioned differently. Use extra caution not to force the lamps when
replacing.
•
Installation of both lamp modules (Lamp 1 and Lamp 2) is required to operate the
projector in dual or single lamp mode. If only a single lamp module is installed, the
projector's lamp will not turn on and will appear as a lamp failure.

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 attemp 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 broke, resulting
in possible injury. In addition, viewing at high elevations can also be potentially
hazardous. Do not attemp to replace the lamp by yourself.
•
Always use lamp "TLPLW25" (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.

•
burn injuries.
