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.
