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 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 : (
GND, the ISOLATED (NEUTRAL) : (
EARTH : (
) side GND. Don't short between the LIVE
) side GND and
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 B1 setting should be checked or
adjusted (See ADJUSTMENT OF B1 POWER SUPPLY).
(6) The high voltage applied to the picture tube must conform
with that specified in Service manual. Excessive high
voltage can cause an increase in X-Ray emission, arcing
and possible component damage, therefore operation
under excessive high voltage conditions should be kept
to a minimum, or should be prevented. If severe arcing
occurs, remove the AC power immediately and determine
the cause by visual inspection (incorrect installation,
cracked or melted high voltage harness, poor soldering,
etc.). To maintain the proper minimum level of soft X-Ray
emission, components in the high voltage circuitry
including the picture tube must be the exact replacements
or alternatives approved by the manufacturer of the
complete product.
(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 10kΩ
2W resistor to the anode button.
) side
(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 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 1000 ohms 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. 3 PRECAUTIONS REGARDING PDP
1.3.1 PRECAUTIONS DURING NOTES FOR TRANSPORTATION
When transporting the display unit, pressure exerted on the
internal PDP (Pplasma Ddisplay Ppanel) 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 horizontally
Ensure 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.
1.3.4 OPTICAL FILER (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.
1.3.2 RESIDUAL IMAGE / BURN-IN ON SCREEN
Like CRTs, "burn-in" 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.

2. 4 TECHNICAL INFORMATION
2.4.1 PDP STRUCTURE AND CHARACTERISTIC
This unit (Display Unit) uses the flat type panel PDP (Plasma Display Panel), instead of the conventional CRT (Cathode Ray Tube),
as a display unit.
2.4.1.1 PIXEL (CELL) ARRAY
PDP is constructed by sealing the xenon, which emits neon and ultraviolet rays for discharging purpose, in between the electrodes
lay on the front glass substrate and rear glass substrate.
One pixel is composed of 3 RGB cells, with cell pitch of 0.365mm (1 pixel 1.095mm) horizontally and 1.110mm vertically.
The cell is arrayed in each RGB color as shown in Fig. 1. One pixel is formed by interlacing each RGB color cell.
One cell size is 0.365mm horizontally and 1.110mm vertically.

2.4.1.2 PIXEL DEFECTS
Though PDP is made by means of ultra precise technology, there are cases whereby not all pixels (cell) will function properly. In
some cases, there may be defective pixels that do not light at all or the ones that always light on.
There are 3 types of Pixel defects, [Bright Dot Defects], [Dark Dot Defects] and [Flicker Dot Defects], as defined respectively in the
following:
(1) Bright Dot Defects
Bright dot defect is a pixel cell that lights though it should not light.
The presence of bright dot defects can be confirmed by inputting a full black signal (pattern).
(2) Dark Dot Defects
Dark dot defect is a pixel cell that does not light, though it should light.
The presence of dark dot defects can be confirmed by inputting a 100% full white signal (pattern).
(3) Flicker Dot Defects
Flicker dot defect is a pixel cell that blinks though it should light or not light.
The presence of flicher dot defects can be confirmed by inputting a full black signal (pattern).
