SECTION 1PRECAUTION
1.1 SAFETY PRECAUTIONS [EXCEPT FOR UK](1) The design of this
product contains special hardware,
many circuits and components specially for safetypurposes. For
continued protection, no changes should bemade to the original
design unless authorized in writing bythe manufacturer. Replacement
parts must be identical tothose used in the original circuits.
Service should beperformed by qualified personnel only.
(2) Alterations of the design or circuitry of the products
shouldnot be made. Any design alterations or additions will voidthe
manufacturer's warranty and will further relieve themanufacturer of
responsibility for personal injury orproperty damage resulting
therefrom.
(3) Many electrical and mechanical parts in the products
havespecial safety-related characteristics. Thesecharacteristics
are often not evident from visual inspectionnor can the protection
afforded by them necessarily beobtained by using replacement
components rated forhigher voltage, wattage, etc. Replacement parts
whichhave these special safety characteristics are identified inthe
parts list of Service manual. Electrical componentshaving such
features are identified by shading on theschematics and by ( ) on
the parts list in Servicemanual. The use of a substitute
replacement which doesnot have the same safety characteristics as
therecommended replacement part shown in the parts list ofService
manual may cause shock, fire, or other hazards.
(4) Don't short between the LIVE side ground andISOLATED
(NEUTRAL) side ground or EARTH sideground when repairing. Some
model's power circuit is partly different in the GND.The difference
of the GND is shown by the LIVE : ( ) sideGND, the ISOLATED
(NEUTRAL) : ( ) side GND andEARTH : ( ) side GND. Don't short
between the LIVE side GND and ISOLATED(NEUTRAL) side GND or EARTH
side GND and nevermeasure the LIVE side GND and ISOLATED
(NEUTRAL)side GND or EARTH side GND at the same time with
ameasuring apparatus (oscilloscope etc.). If above note willnot be
kept, a fuse or any parts will be broken.
(5) When service is required, observe the original lead
dress.Extra precaution should be given to assure correct leaddress
in the high voltage circuit area. Where a short circuithas
occurred, those components that indicate evidence ofoverheating
should be replaced. Always use themanufacturer's replacement
components.
(6) Isolation Check (Safety for Electrical Shock Hazard) After
re-assembling the product, always perform anisolation check on the
exposed metal parts of the cabinet(antenna terminals, video/audio
input and output terminals,Control knobs, metal cabinet, screw
heads, earphone jack,control shafts, etc.) to be sure the product
is safe to operatewithout danger of electrical shock.
a) Dielectric Strength Test The isolation between the AC primary
circuit and all metalparts exposed to the user, particularly any
exposed metalpart having a return path to the chassis should
withstand avoltage of 3000V AC (r.m.s.) for a period of one second.
(.. . . Withstand a voltage of 1100V AC (r.m.s.) to anappliance
rated up to 120V, and 3000V AC (r.m.s.) to anappliance rated 200V
or more, for a period of one second.) This method of test requires
a test equipment not generallyfound in the service trade.
b) Leakage Current Check Plug the AC line cord directly into the
AC outlet (do not usea line isolation transformer during this
check.). Using a"Leakage Current Tester", measure the leakage
currentfrom each exposed metal part of the cabinet, particularlyany
exposed metal part having a return path to the chassis,to a known
good earth ground (water pipe, etc.). Anyleakage current must not
exceed 0.5mA AC (r.m.s.). However, in tropical area, this must not
exceed 0.2mA AC(r.m.s.). Alternate Check Method
Plug the AC line cord directly into the AC outlet (do notuse a
line isolation transformer during this check.). Usean AC voltmeter
having 1000 per volt or moresensitivity in the following manner.
Connect a 150010W resistor paralleled by a 0.15F AC-type
capacitorbetween an exposed metal part and a known good earthground
(water pipe, etc.). Measure the AC voltageacross the resistor with
the AC voltmeter. Move theresistor connection to each exposed metal
part,particularly any exposed metal part having a return pathto the
chassis, and measure the AC voltage across theresistor. Now,
reverse the plug in the AC outlet andrepeat each measurement. Any
voltage measured mustnot exceed 0.75V AC (r.m.s.). This corresponds
to0.5mA AC (r.m.s.). However, in tropical area, this must not
exceed 0.3V AC(r.m.s.). This corresponds to 0.2mA AC (r.m.s.).

transporters.Ensure that the following requirements are met
duringtransportation, as the LCD panel of this unit is made of
glass andtherefore fragile:
(1) USE A SPECIAL PACKING CASE FOR THE LCD PANELWhen
transporting the LCD panel of the unit, use a specialpacking case
(packing materials). A special packing caseis used when a LCD panel
is supplied as a service sparepart.
(2) ATTACH PROTECTION SHEET TO THE FRONTSince the front (display
part) of the panel is vulnerable,attach the protection sheet to the
front of the LCD panelbefore transportation. Protection sheet is
used when a LCDpanel is supplied as a service spare part.
(3) AVOID VIBRATIONS AND IMPACTSThe unit may be broken if it is
toppled sideways even whenproperly packed. Continuous vibration may
shift the gap ofthe panel, and the unit may not be able to display
imagesproperly. Ensure that the unit is carried by at least
2persons and pay careful attention not to exert any vibrationor
impact on it.
(4) DO NOT PLACE EQUIPMENT HORIZONTALLYEnsure that it is placed
upright and not horizontally duringtransportation and storage as
the LCD panel is veryvulnerable to lateral impacts and may break.
Duringtransportation, ensure that the unit is loaded along
thetraveling direction of the vehicle, and avoid stacking themon
one another. For storage, ensure that they are stackedin 2 layers
or less even when placed upright.
1.4.2 OPTICAL FILTER (ON THE FRONT OF THE LCD PANEL)(1) Avoid
placing the unit under direct sunlight over a
prolonged period of time. This may cause the optical filterto
deteriorate in quality and COLOUR.
(2) Clean the filter surface by wiping it softly and lightly
with asoft and lightly fuzz cloth (such as outing flannel).
(3) Do not use solvents such as benzene or thinner to wipe
thefilter surface. This may cause the filter to deteriorate
inquality or the coating on the surface to come off. Whencleaning
the filter, usually use the neutral detergent dilutedwith water.
When cleaning the dirty filter, use water-dilutedethanol.
(4) Since the filter surface is fragile, do not scratch or hit
it withhard materials. Be careful enough not to touch the
frontsurface, especially when taking the unit out of the
packingcase or during transportation.
1.4.3 PRECAUTIONS FOR REPLACEMENT OF EXTERIORPARTS
Take note of the following when replacing exterior parts
(REARCOVER, FRONT PANEL, etc.):
(1) Do not exert pressure on the front of the LCD panel
(filtersurface). It may cause irregular COLOUR.
(2) Pay careful attention not to scratch or stain the front of
theLCD panel (filter surface) with hands.
(3) When replacing exterior parts, the front (LCD panel)
shouldbe placed facing downward. Place a mat, etc. underneathto
avoid causing scratches to the front (filter surface).

5.NOTE FOR REPAIRING SERVICE
This model's power circuit is partly different in the GND.
The
difference of the GND is shown by the LIVE : ( ) side GND and
the
ISOLATED(NEUTRAL) : ( ) side GND. Therefore, care must be
taken for the following points.
(1)Do not touch the LIVE side GND or the LIVE side GND and
the
ISOLATED(NEUTRAL) side GND simultaneously. if the above
caution is not respected, an electric shock may be caused.
Therefore, make sure that the power cord is surely removed
from
the receptacle when, for example, the chassis is pulled out.
(2)Do not short between the LIVE side GND and
ISOLATED(NEUTRAL)
side GND or never measure with a measuring apparatus measure
with a measuring apparatus ( oscilloscope, etc.) the LIVE side
GND
and ISOLATED(NEUTRAL) side GND at the same time.
If the above precaution is not respected, a fuse or any parts
will be broken.
Since the circuit diagram is a standard one, the circuit and
circuit constants may be subject to change for improvement
without any notice.
NOTE
Due improvement in performance, some part numbers show
in the circuit diagram may not agree with those indicated in
the part list.
When ordering parts, please use the numbers that appear
in the Parts List.
