SECTION 1
PRECAUTION
1.1 SAFETY PRECAUTIONS
(1) The design of this product contains special hardware, many
circuits and components specially for safety purposes. For
continued protection, no changes should be made to the original
design unless authorized in writing by the manufacturer.
Replacement parts must be identical to those used in the original
circuits. Service should be performed by qualified personnel only.
(2) Alterations of the design or circuitry of the products should not be
made. Any design alterations or additions will void the
manufacturer's warranty and will further relieve the manufacturer
of responsibility for personal injury or property damage resulting
therefrom.
(3) Many electrical and mechanical parts in the products have special
safety-related characteristics. These characteristics are often not
evident from visualinspectionnor can the protectionaffordedby them
necessarily be obtained by using replacement components rated for
higher voltage, wattage, etc. Replacement parts which have these
special safety characteristics are identified in the parts list of Service
manual. Electrical components having such features are
identified by shading on the schematics and by ( ) on the
parts list in Service manual. The use of a substitute replacement
which does not have the same safety characteristics as the
recommended replacement part shown in the parts list of Service
manual may cause shock, fire, or other hazards.
(4) Use isolation transformer when hot chassis.
The chassis and any sub-chassis contained in some products are
connected to one side of the AC power line. An isolation
transformer of adequate capacity should be inserted between the
product and the AC power supply point while performing any
service on some products when the HOT chassis is exposed.
(5) Don't short between the LIVE side ground and ISOLATED (NEU-
TRAL) side ground or EARTH side ground when repairing.
Some model's power circuit is partly different in the GND. The differ-
ence of the GND is shownby the LIVE :( ) side GND, the ISOLAT-
ED (NEUTRAL) : ( ) side GND and EARTH : ( ) side GND.
Don't short between the LIVE side GND and ISOLATED (NEUTRAL)
side GND or EARTH side GND and never measure the LIVE side
GND and ISOLATED (NEUTRAL) side GND or EARTH side GND at
the same time with a measuring apparatus (oscilloscope etc.). If
above note will not be kept, a fuse or any parts will be broken.
(6) If any repair has been made to the chassis, it is recommended that
the B1 setting should be checked or adjusted (See B1 POWER
SUPPLY check).
(7) Do not check high voltage by drawing an arc. Use a high voltage
meter or a high voltage probe with a VTVM. Discharge the picture
tube before attempting meter connection, by connecting a clip lead
to the ground frame and connecting the other end of the lead
through a 10kΩ2W resistor to the anode button.
(8) When service is required, observe the original lead dress. Extra
precaution should be given to assure correct lead dress in the high
voltage circuit area. Where a short circuit has occurred, those
components that indicate evidence of overheating should be
replaced. Always use the manufacturer's replacement
components.
(9) Isolation Check (Safety for Electrical Shock Hazard)
After re-assembling the product, always perform an isolation
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 operate without danger of electrical
shock.
a) Dielectric Strength Test
The isolation between the AC primary circuit and all metal parts
exposed to the user, particularly any exposed metal part having a
return path to the chassis should withstand a voltage of 1100V AC
(r.m.s.) for a period of one second.
(. . . . Withstand a voltage of 1100V AC (r.m.s.) to an appliance rat-
ed up to 120V, and 3000V AC (r.m.s.) to an appliance rated 200V
or more, for a period of one second.) This method of test requires
a test equipment not generally found in the service trade.
b) Leakage Current Check
Plug the AC line cord directly into the AC outlet (do not use a line
isolation transformer during this check.). Using a "Leakage
Current Tester", measure the leakage current from each exposed
metal part of the cabinet, particularly any exposed metal part
having a return path to the chassis, to a known good earth ground
(water pipe, etc.). Any leakage current must not exceed 0.5mA AC
(r.m.s.).
However, in tropical area, this must notexceed 0.2mA AC (r.m.s.).
Alternate Check Method
Plug the AC line cord directly into the AC outlet (do not use a
line isolation transformer during this check.). Use an AC
voltmeter having 1000Ωper volt or more sensitivity in the
following manner. Connect a 1500Ω10W resistor paralleled by
a0.15µF AC-type capacitor between an exposed metal part and
a known good earth ground (water pipe, etc.). Measure the AC
voltage across the resistor with the AC voltmeter. Move the
resistor connection to each exposed metal part, particularly any
exposed metal part having a return path to the chassis, and
measure the AC voltage across the resistor. Now, reverse the
plug in the AC outlet and repeat each measurement. Any
voltage measured must not exceed 0.75V AC (r.m.s.). This
corresponds to 0.5mA 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.).
(10) High voltage hold down circuit check.
After repair of the high voltage hold down circuit, this circuit shall
be checked to operate correctly.See item "How to check the high
voltage hold down circuit".

efficiency may deteriorate and temperature inside the unit will
rise. The temperature sensor that protects the unit will be
activated when internal temperature exceeds the pre-determined
level and power will be turned off automatically.Therefore,
please make sure pay attention not to block the heat dissipation
vent as well as the ventilation outlet behind the unit and ensure
that there is room for ventilation around it.
1.2.2 INSTALLATION REQUIREMENTS
Ensure that the minimal distance is maintained, as specified
below, between the unit with and the surrounding walls, as well
as the floor etc.Install the unit on stable flooring or stands.Take
precautionary measures to prevent the unit from tipping in order
to protect against accidents and earthquakes.

1.3 HANDLING FOR PLASMA DISPLAY PANEL
1.3.1 PRECAUTIONS DURINGNOTESFORTRANSPORTATION
When transporting the display unit, pressure exerted on the
internal PDP (Plasma Display Panel) due to improper handling
(such as tossing and dropping) may cause damages even when
the unit is carefully packed. To prevent accidents from occurring
during transportation, pay careful attention prior to delivery such
as through explaining the handling instructions to transporters.
Ensure that the following requirements are met during
transportation, as the PDP of this unit is made of glass and
therefore fragile:
(1) Avoid vibrations and impacts
The unit may be broken if it is toppled sideways even when
properly packed. Ensure that the unit is carried by at least
2 persons and pay careful attention not to exert any
vibration or impact on it.
(2) Do not place equipment horizontallyEnsure that it is placed
upright and not horizontally during transportation and
storage as the PDP is very vulnerable to lateral impacts
and may break easily under such circumstances.During
transportation, ensure that the unit is loaded along the
traveling direction of travel of the vehicle, and avoid
stacking them on one another.For storage, ensure that
they are stacked in 2 layers or less even when placed
upright.
1.3.2 RESIDUAL IMAGE / BURN-IN ON SCREEN
Like CRTs, ‘burn-ins’ may occur when a same image is
continuously displayed over an extended period of time.As Tthis
may also shorten the life span of the PDP. Therefore, turn off the
display when not in use, scroll the screen, make use of screen-
savers, or allow even distribution on the display by inverting the
brightness, switching to complementary colors or inserting
animated images at periodic intervals.As burn-in is more likely to
occur with high brightness and contrast settings, try to use
neutral gradations or medium tone colors.Burn-in does not occur
in the case of animated images.When switching to another
image after continuous display of the previous image, residual
images may become prominent, as luminance in a part of the
display is higher than the other parts. This is not a defect but is
because due to the discharge surface of the lighted portion has
becomebeing relatively activated and its luminance higher than
the unlighted parts.
1.3.3 INFRARED RAYS
Near Near-infrared rays (800nm to 1000nm) are emitted from the
front of the panel, and this may give rise to glitchescause
malfunctions in infrared remote controls or communication
systems placed near it. In this case, avoid direct infrared rays
(and reflected rays in some cases) from the screen by either
changing the direction of the unit or other infrared systems or
securing a longer keeping a distance from the screen.
1.3.4 OPTICAL FILTER (PANEL FILTER)
Avoid placing the unit under direct sunlight over a prolonged
period of time. This may cause the optical filter to deteriorate in
quality and color.Clean the filter surface by wiping it softly lightly
with outing flannels a soft and lightly fuzz cloth (such as
flannel).Do not use solvents such as benzine or thinner to wipe
the filter surface. This may cause the filter to deteriorate in quality
or the coating on the surface to come off.As Tthe filter surface is
fragile., Ddo not scratch or hit it with hard materials.
1.3.5 NOTES PRECAUTIONS FOR REPLACEMENT OF
EXTERIOR PARTS
Take note of the following when replacing exterior parts (back
REAR COVER, FRONT PANEL, optical filter):Do not exert
pressure on the front of the PDP (glass surface).Pay careful
attention not to scratch or stain the front of the PDP (surface) with
hands.When replacing exterior parts, the front of the PDP should
be placed facing downward. Place a mat, etc. underneath to
avoid causing scratches to the front surface.However, never use
materials that are too soft (such as blanket cloth). If replacement
is made with the PDP surface facing downward and in contact
with the blanket, pressure may be exerted on the PDP, thus
causing damages to it.
