Cabinet Cleaning
• Wipe the front panel and other exterior surfaces of the unit with a soft
cloth immersed in lukewarm water and wrung dry.
• Never use a solvent or alcohol. Do not spray insecticide liquid near the
unit. Such chemicals may cause damage and discoloration to the exposed
surfaces.
Servicing
Should your unit become inoperative, do not try to correct the problem
yourself. There are no user serviceable parts inside. Turn off the unit,
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.
Picture Tube Cleaning
Wipe the picture tube of the TV with a soft cloth. Before cleaning the
picture tube, disconnect the power cord.
Degaussing
A degaussing circuit in this unit clears up color errors on the TV screen.
Color errors occur when there is any excess magnetism close to the unit.
This circuit is designed to operate once when the unit is fi rst plugged
in. If you see minor color errors on the screen, unplug the unit for
approximately 30 minutes. When you plug the unit again, the degaussing
circuit will operate to clear errors. Take this step any time the TV screen is
accidentally magnetized or when you move the unit.
IR Signal Check
If the remote control is not working properly, you can use an AM radio or
digital camera (including a cellular 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 fl utters, 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.
