(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 visual inspection
nor can the protection afforded by 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) Don't short between the LIVE side ground and
ISOLATED (NEUTRAL) side ground or EARTH side
ground when repairing.
Some model's power circuit is partly different in the GND.
The difference of the GND is shown by the LIVE : ( ) side
GND, the ISOLATED (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.
(5) If any repair has been made to the chassis, it is
recommended that the PDP voltage setting should be
checked or adjusted.
(6) 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.
(7) 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 3000V AC (r.m.s.) for a period of one second. (.
. . . Withstand a voltage of 1100V AC (r.m.s.) to an
appliance rated 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 not exceed 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 1000Ω per volt or more
sensitivity in the following manner. Connect a 1500Ω
10W resistor paralleled by a 0.15µF 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.).

1.2INSTALLATION
1.2.1 REQUIREMENTS FOR SETTING
The following minimum space must be kept when a PDP is installed.
(The recommended distance should be from the most projected portion when a PDP is inclined.)
An insufficient space reduces cooling efficiency and raises the internal temperature. If the internal temperature rises over the reference
value, the temperature sensor works to turn the power off for protecting the main body. Therefore, vents on the backside of the main
body such as heat dissipation vents must not be blocked, and sufficient spaces for heat dissipation must be kept around the main body.

Preventing the radiation of heat from
each side causes high temperature
within a PDP and may damage the
inner circuit.
Install a PDP in a place where is well
ventilated.
Ambient temperature should be within a
range of 0 ~40 .

The structure and strength of the wall
where a PDP is installed should be
checked beforehand so as to install the
PDP safety without any accident.
In the case of vertical setting, 2
exclusive cooling fans(option) should be
attached.
Additionally, the rotation of internal
cooling fans should be "high "(see also
the instruction manual).
A PDP should be installed on a rigid
floor or stand.
In order to prevent a PDP from turning
over by an accident or earthquake,
safety measures should be considered.

1.2.2 PRECAUTION DURING NOTES FOR TRANSPORTATION
When transporting the display unit, pressure exerted on the
internal PDP (Plasma Display Panel) due to improper handing
(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 exchanging the handing 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 lay a PDP on its side.
A PDP should always be placed upright during both
transportation and safekeeping. Don't lay it on its side. The
panel of a PDP is very fragile to the impact in the horizontal
direction.
When a car carries a PDP, load it on board the car in
parallel with the moving direction of the car. Don't lay
several PDPs one on top another.
During safekeeping, don't lay more than two PDPs one on
top another even if they are kept upright.
1.2.4 RETAINED-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 this 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
inverting 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 dose 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 then the other parts.
This is not a defect but is because due to the discharge surface
of the lighted portion has become being relatively activated and
its luminance higher than the unlighted parts.
1.2.5 BRIGHTNESS CHANGE IN THE SCREEN
In order to save the power consumption, the power is controlled
(with APS function) depending on the brightness of the screen.
For this, the brightness may change after a short time when the
picture of the screen is changed. However, this phenomenon is
not a trouble.
1.2.3 HEAT DISSIPATION IN THE CASE OF VERTICAL
SETTING
In the case of vertical installation, it is required to attach 2
exclusive cooling fans(option) in order to help dissipate the heat
within the PDP unit. Connect the DC power code of exclusive
cooling fans to the exclusive optional terminal.
If you install the PDP in other ways such as on the angle, not only
cooling fans but additional methods are required to cool down the
PDP depending on the thermal environment.
An option terminal is exclusively
for a cooling fan. Please do not
use it for connection with other
apparatus

1.2.6 INFRARED RAYS
Because the near infrared rays (800nm~1000nm) radiate from
the panel face, the neighboring infrared ray remote controllers,
infrared communication systems, etc. may malfunction. In these
cases, take a measure to prevent the trouble to be caused by
direct rays (or reflected rays) from the screen by changing the
direction of the screen face or keeping a safe distance between
a PDP and other devices.
1.2.7 OPTICAL FILTER (FRONT 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 a flannel).
Do not use solvents such as benzene 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 the filter surface is fragile. Do not scratch or hit it with hard
materials.
1.2.8 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 met, etc. underneath to avoid
causing scratched 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.
