About the LCD Projection TV
Although the LCD projection TV is made with high-
precision technology, black dots may appear or bright
points of light (red, blue, or green) may appear constantly
on the LCD screen. This is a structural property of the
LCD panel.
If direct sunlight or other strong illumination shines
on the screen, part of the screen may appear white
due to reflections from behind the screen. This is a
structural property of the LCD projection TV.
Do not expose the screen to direct illumination or
direct sunlight.
The picture quality may be affected by your viewing
position. Sit at least approx. 5.9 ft. (1.8 m) for KF-
42WE620 or approx. 6.6 ft. (2.0 m) for KF-
50WE620 away from your LCD projection TV, and
within 60° of the vertical and 130° of the horizontal
viewing area.
If you sit too close to the TV, you may experience
eye strain. For the best picture quality, install your
LCD projection TV according to "Recommended
Viewing Area" on page 24.
When installing your LCD projection TV against a
wall, keep it at least 4 inches (10 cm) from the wall.
Avoid installing the LCD projection TV close to
high temperature sources such as a heater.
Projection lamp
Your LCD projection TV uses a projection lamp as
its light source. It is time to replace the lamp with a
new one (not supplied) when:
• the lamp replacement indicator of the front panel
blinks in red,
• screen images become dark,
• no image appears on the display after prolonged
In rare instances, the bulb may pop inside the lamp
unit, but the lamp unit is desinged to contain all of
broken glass pieces inside the lamp unit. (See
"Replacing the Lamp" on page 15.)
Cooling fan
This LCD projection TV uses a cooling fan. You
may hear the noise of fan running, depending on the
placement of your LCD projection TV. The noise
may be more noticeable during the night or when the
background noise level is low.
Remote control detection
The remote control sensor is in the middle of the TV
on the bottom. For the best results, aim the remote
control at this location.
