correct the problem by yourself. There are no
userserviceable parts inside. Turn off, unplug the
power cord and please call our help line mentioned
on the front page, to locate an Authorized Service

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 first plugged in.
If you see minor color errors on the screen,
unplug the unit for approximately 30 minutes.
When you plug in the unit again, the degaussing cir-
cuit 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 doesn’t work properly, you can
test if the remote control sends out the infrared sig-
nal with AM radio or a digital camera (including built-
in camera of cellular phone). It will help to define the
cause of malfunction.
•
With an AM radio
:
Tune an AM radio to a station with
no broadcasting. Press a button
on remote control toward the
radio. Sound will be fluttering
when you press any key and the
radio receives the signal. This
means the remote control unit is
working.
•
With a digital camera
(including
built-in camera of cellular phone):
Direct a digital camera to remote con-
trol, press and hold a button on
remote control. If infrared light
appears through digital camera, the
remote control is working.
