1.
Here's
a
great
way
to
keep
the
dust
off
your
screen
for
a
while.
Wet
a
soft
cloth
in
a
mixture
of
lukewarm
water
and
a
little
fabric
softener
or
dish
washing
detergent.
Wring
the
cloth
until
it's
almost
dry,
and
then
use
it
to
wipe
the
screen.
2.
Make
sure
the
excess
water
is
off
the
screen,
and
then
let
it
air-dry
before
you
turn
on
your
TV.
To
remove
dirt
or
dust,
wipe
the
cabinet
with
a
soft,
dry,
lint-free
cloth.
Please
do
not
use
a
wet
cloth.
If
you
expect
to
leave
your
TV
dormant
for
a
long
time
(such
as a
vacation),
it's
a
good
idea
to
unplug
the
power
cord
to
protect
against
possible
damage
from
lightning
or
power
surges.
-
Early
malfunctions
can
be
prevented.
Careful
and
regular
cleaning
can
extend
the
amount
of
time
you
will
have
your
new
TV.
Be
sure
to
turn
the
power
off
and
unplug
the
power
cord
before
you
begin
any
cleaning.
