Lamp unit replacement and care

Replacing the lamp unit

(User-replaceable component)

WARNING: RISK OF

ELECTRIC SHOCK!

TO REDUCE THE RISK OF ELECTRIC SHOCK, NEVER REMOVE TV COVERS, EXCEPT AS SPECIFIED HEREIN. REFER ALL SERVICING NOT SPECIFIED IN THIS MANUAL TO QUALIFIED SERVICE PERSONNEL. Failure to follow this WARNING may result in death or serious injury.

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 72 for information on switching the lamp mode. Because these are averages, some lamps will require earlier replacement.

Note : The lamp is warranted only for the periods and to the extent set forth in the Limited Warranty applicable to this set, which is a substantially shorter period of time than the average useful service period. See “Limited United States Warranty” on page 102 or “Limited Canada Warranty” on page 103, 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.

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, 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, page 94); or

•if you hear a loud noise and the picture goes black, which may indicate a lamp rupture (LED indication #3, page 94).
