CABINET CLEANING
• Always unplug the TV from the AC outlet before
cleaning.
• Clean the case of the TV with a soft cloth which
has been wet and wrung dry.
• If the screen is dirty or dusty, wipe it clean with a
soft cloth.
NOTES:
•
Never use a solvent, alcohol or any other abrasive liquid
to clean the TV.
•
Always make sure the area around vents on the TV is
clear and clean. Failure to do this may result in fire or
cause the TV to fail prematurely.
SERVICING
Should your unit become inoperative, do not try to
correct the problem yourself. There are no user ser-
viceable parts inside. Turn off the TV, unplug the
power cord and call our toll free customer support
line found on the cover of this manual to locate an
authorized service center.
IR SIGNAL CHECK
If the remote control isn’t working properly, you can
use an AM radio or digital camera (including a cellu-
lar phone with built-in camera) to see if it is sending
out an infrared signal.
•
With an AM radio
:
Tune the AM radio station to a
non-broadcasting frequency.
Point the remote control towards
it, push any button and listen. If
the sound from the radio flutters,
it is receiving the remote control’s
infrared signal.
•
With a digital camera
(including built-
in cell phone cameras):
Point a digital camera towards the
remote control. Push any button on
the remote control and look through
the digital camera. If the infrared light
appears through the camera, the
remote control is working.
