Important notes about your DLP ™ projection TV
1) The light source for this TV is a projection lamp unit with a
limited service life. When the lamp wears out, the picture
may become dark or black, or the lamp may fail, at which
time you must replace the lamp unit. See “Lamp unit
replacement” on pages 60-64.
2) Each time you turn on the TV, it may take up to several
seconds to go from no picture to full picture brightness.
3) The display on this TV is manufactured using a chip that may
contain up to 1.3 million microscopic mirrors. Each of these
micromirrors measures less than one-fifth the width of a
human hair and represents a single pixel on the television
display. These micromirrors are mounted on tiny hinges that
enable them to tilt either toward the light source (ON) or
away from it (OFF). Occasionally, one of these mirrors may
become inoperative, creating a light or dark pixel on the
projection surface. This is a structural property of DLP™
projection TV technology, and is not a sign of malfunction.
Such pixels are not visible when the picture is viewed from a
normal viewing distance (see item 29 on page 4).
4) Depending on the media you are viewing, it is possible,
although unlikely, that a limited number of viewers may
see a “rainbow effect” on the screen, which can, in rare
instances, result in eye fatigue. This is a rare occurrence
related to technology of this type, and is not a sign of TV
malfunction.
5) Always sit approximately 10–25 feet away from the TV and
as directly in front of it as possible. The picture quality may
be affected by your viewing position and length of viewing
time. If you sit too closely to the TV for too long, you may
suffer from eye fatigue. See item 29 on page 4.
6) This TV contains several cooling fans to moderate
the internal temperature. You may be able to hear
the fans for several minutes after the TV is turned
off. This is a function of the Quick Restart standby mode
and is not a sign of TV malfunction. You can set the Quick
Restart feature to stop the fans as soon as the TV is
turned off. See “Selecting the Quick Restart” on page 28.
7) The green and red LED lights on the control touchpad (on
the lower right corner of the TV screen) indicate your TV’s
current status. If either light flashes, see “LED indications”
on page 64 for details.
8) Review all safety and operating information in this owner’s
manual before you use your TV.
