Cleaning
s
Clean the rear cover area of the TV regularly. Dust in the rear cover
area may cause a problem with the cooling system of the TV set.
s
Clean the cabinet of the TV with a dry soft
cloth. To remove dust from the screen, wipe it
gently with a soft cloth. Stubborn stains may be
removed with a cloth slightly dampened with
solution of mild soap and warm water. Never
use strong solvents such as thinner or benzine for cleaning. If the
picture becomes dark after using the TV for a long period of time, it
may be necessary to clean the inside of the TV. Consult qualified
service personnel.
s
Unplug the AC power cord when cleaning this unit. Cleaning this
unit with a plugged AC power cord may result in electric shock.
On Contamination on the Screen Surface
The screen surface has a special coating to reduce reflections. To prevent
screen damage, clean the screen as follows:
s
Clean the screen with a soft cloth.
s
To remove hard contamination, use a cloth moistened with a
solution of mild soap and warm water. Do not spray cleaning
solution directly onto the TV. It should only be sprayed to moisten
the cleaning cloth.

Do not use any type of abrasive pad, alkaline cleaner, acid cleaner,
scouring powder, chemical cloth, or solvent such as alcohol,
benzene or thinner, as these may scratch the screen's coating.

For Safety

Be Careful When Moving the
TV
When you place the TV in position, be careful
not to drop it on your foot or fingers.
Watch your footing while installing the TV.
Carry the TV in the Specified
Manner
If you carry the TV in a manner other than the
specified manner and without the specified number
of persons, it may drop and a serious injury may be
caused. Be sure to follow the instructions
mentioned below.
s
Carry the TV with the specified number of persons (see page 11).
s
Hold the TV tightly when carrying it.
s
Before carrying the TV, disconnect any accessories or cables.
About the TV
Although the 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 screen. This is a structural property of the panel and is not a defect.
Installation
s
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 TV.
Do not expose the screen to direct illumination or direct sunlight.
s
The picture quality may be affected by your viewing position. For
the best picture quality, install your TV according to
"Recommended Viewing Area" on page 13.
s
When installing your TV against a wall, keep it at least 4 inches (10
cm) away from the wall.

Projection Lamp

s
Your TV uses a projection lamp as its light source. It is time to
replace the lamp with a new one (not supplied) when:
• the message, "Projection lamp is nearing end of life. Please
replace the lamp." appeared on the screen,
• the lamp replacement indicator on the front panel blinks in red,
• screen images become dark,
• no image appears on the display after prolonged use.
s
In rare instances, the bulb may pop inside the lamp unit, but the lamp
unit is designed to contain all of broken glass pieces inside the lamp
unit. (See "Replacing the Lamp" on page 51.)
s
When the lamp eventually burns out, you may hear a noticeable pop
sound. This is normal and is inherent in this type of lamp.
Cooling Fan
This TV uses a cooling fan. You may hear the noise of fan running,
depending on the placement of your TV. The noise may be more noticeable
during the night or when the background noise level is low.
Objects and Ventilation Holes
Never push objects of any kind into the unit through
the cabinet slots as they may touch dangerous
voltage points or short out parts that could result in
a fire or electric shock. Never spill liquid of any
kind on the unit.
Disposal of Used Batteries
To preserve our environment, dispose of used batteries according to your
local laws or regulations.
