Maintenance
Routine
TV
Cabinet
and
Screen
Cleaning
Careful
and
regular
cleaning
can
extend
the the
useful
service
life
of
the
TV.
Be
sure
to
turn
the
power
Off
and
pull
out
the
power
cord before
you
begin
any
cleaning.
Screen
Cleaning
1.
Here's
a
great
way
to
keep
the
dust
off
the
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
the
TV
air-dry
before
turning
it
On.
Cabinet
Cleaning
1.
Use
a
soft
cloth
with
a
mild
soap
solution
to
wipe
the
cabinet.
(Avoid
using
any
harsh,
industrial
strength
variety
of
cleaner.)
2.
Rinse
the
cloth
and
wipe
the
cabinet
again.
3.
Let
the
cabinet
air-dry
before
turning
the
TV
on.
Extended
Absence
If
the
TV
will
be
dormant
for
a
long
time,
it's
a
good
idea
to
unplug
the
power
to
protect
against
possible
damage
from
lightning
or
power
surges.
If
you
use
off-air
antennas,
you
may
also
want
to
disconnect
them
from
the
back
of
the
TV.
If
you
unplug
the
TV,
you
may
have
to
reset
the
clock
using
the
Clock
Set
menu
described
earlier.
