Lamp unit replacement
(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. The average useful service life for the lamp is
approximately 8,000 hours in LOW POWER mode or 6,000 hours in
HI BRIGHT mode. See “Selecting the Lamp mode” on page 46 for
information on switching the lamp mode. Because these are averages,
some lamps will require earlier replacement.
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.
Note: The lamp unit is designed so broken lamp glass remains securely
inside the lamp unit.
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 3); or
• if you hear a loud noise and the picture goes black, which may
indicate a lamp rupture (LED Indication 3). See “LED indications”
on page 60.
