CABINET CLEANING
• Wipe the front panel and other exterior surfaces of
the TV with a soft cloth immersed in lukewarm
water and wrung dry.
• Never use a solvent or alcohol. Do not spray
insecticide liquid near the TV. Such chemicals
may cause damage and discoloration to the
exposed surfaces.
PICTURE TUBE CLEANING
Wipe the picture tube of the TV with a soft cloth.
Before cleaning the picture tube, disconnect the
power cord.
SERVICING
Should your unit become inoperative, do not try to
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
Center.
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 broadcast-
ing. Press any button on remote control toward
the radio. Sound will be flutter-
ing when you press any key
and the radio receives the sig-
nal. This means the remote
control unit is working.
• With a digital camera (includ-
ing built-in camera of cellular
phone):
Direct a digital camera to
remote control, press and hold
any button on remote control. If
infrared light appears through digital
camera, the remote control is working.

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 approx-
imately 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 accidental-
ly magnetized or when you move the unit.
AUTO HEAD CLEANING
• Automatically cleans video heads as you insert or
remove a cassette, so you can see a clearer picture.
• Playback picture may become blurred or interrupted
while the TV program reception is clear. Dirt accumulat-
ed on the video heads after long periods of use or the
usage of rental or worn tapes can cause this problem.
If a streaky or snowy picture appears during playback,
the video heads in your unit may need to be cleaned.
1. Please visit your local Audio/Video store and pur-
chase a good quality VHS Video Head Cleaner.
2. If a Video Head Cleaner does not solve the prob-
lem, please call our help line mentioned on the
front page, to locate an Authorized Service Center.
NOTES:
• Remember to read the instructions included with the video
head cleaner before use.
• Clean video heads only when problems occur.
IF THE LASER OPTICAL PICKUP UNIT IS DIRTY
• If the unit still does not perform properly when it is oper-
ated, while referring to the relevant sections and to
"TROUBLESHOOTING GUIDE" in this Owner's Manual,
the laser optical pickup unit may be dirty. Consult your
dealer or an Authorized Service Center for inspection
and cleaning of the laser optical pickup unit.
DISC HANDLING
• Handle the discs so that fingerprints and dust do
not adhere to the surfaces of the discs.
• Always store the disc in its protective case when it
is not used.
• To clean-off, use a soft cloth.
• Do not use a hard cloth since this
will mar the disc.
• Wipe the disc in a straight line from center to edge.
• Never wipe with a circular motion.
• Do not use detergent or abrasive
cleaning agents.
