Lamp unit replacement and care

Replacing the lamp unit

(User-replaceable component)

The light source for this TV is a mercury lamp with internal
atmospheric pressure that increases during use. The lamp has a
limited service life that varies depending on product use and
user settings.
As is generally the case with all projection TVs that use
projection lamps as a light source, the brightness of the lamp
in this TV may vary somewhat over the expected service life
and will generally decrease over time. Because of the many
variables that can affect the useful service life of the lamp, your
experience may vary from other users.
Note : The lamp is warranted only for the periods and to the
extent set forth in the Limited Warranty applicable to this set.
See “Limited United States Warranty” (- page 67) or “Limited
Canadian Warranty” (- page 68), as applicable.
If you use the lamp beyond its service life:
•you may notice a reduction in the colors and/or brightness of
the picture; and
•the strength of the quartz glass in the lamp will be reduced
and the lamp may rupture (often making a loud noise when
this happens). If the lamp ruptures, the TV will not operate
until the lamp unit is replaced.

When to replace the lamp unit

You should replace the lamp unit:
•if the picture darkens and/or colors fade;
•if the screen (lamp) does not light (LED indication #4,
- page 62); or
•if you hear a loud noise and the picture goes black, which
may indicate a lamp rupture (LED indication #4,
- page 62).
To obtain a replacement lamp unit:
Always replace the lamp unit with the model
currently recommended by Toshiba.
For more information, please contact us at the
telephone numbers or websites listed above, as

Using any lamp other than those recommended by
Toshiba may cause damage to the TV and/or lamp.
SUCH DAMAGE IS NOT COVERED UNDER YOUR
TOSHIBA WARRANTY.
