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 will all projection TVÕs 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 ÒLOW POWERÓ mode or [6,000] hours in ÒHI BRIGHTÓ mode. See ÒSelecting the Lamp modeÓ 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.

CAUTION: Always handle the lamp unit with care.

The lamp unit in this TV was designed for safe replacement by consumers; however, if the lamp unit is subjected to intentional abuse (such as excessive mechanical abuse or handling by children or pets), the unit may break, exposing sharp edges or pinch points.

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 ÒLED indicationsÓ on page 60.
