(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 cir cuitry of the pr oducts shou ld n ot 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 me chanical 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 w hich 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 part s 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 difference of the GND is shown by the L IVE : ( ) 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 measu re 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 10kΩ 2W resistor to the anode button.
(8) When service is required, observe the original lea d 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 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.).

1.3HANDLING FOR PLASMA DISPLAY PANEL
1.3.1 PRECAUTIONS DURING NOTES FOR TRANSPORTATION
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 lea st
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 screensavers, 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 b ut is
because due to the discharge surface of th e lighted porti on 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.

TROUBLESHOOTING
5.1SELF-DIAGNOSIS FEATURE
5.1.1 OUTLINE
This unit comes with the "Self-diagnosis" feature, which checks
the operational state of the circuit and displays/saves it during
failure.Diagnosis is performed when power is turned on, and
information input to the main microcomputer is monitored at all
time.Diagnosis is displayed in 2 ways via screen display and LED
flashes. Failure detection is based on input state of I
the various control lines connected to the main microcomputer.
5.1.2 HOW TO ENTER THE SELF-DIAGNOSIS DISPLAY
MODE
(1) Press the [SLEEP TIMER] key and set it to 30 minutes.
(2) Press the [VIDEO STATUS] key and [DISPLY] key
simultaneously, then enter the TEST MODE.
(3) Press the [4] key (Self-diagnosis Display mode) before the
service mode screen disappears.
(4) Press the [MTS] key to enter Page 2 of the Self-diagnosis
Display mode.
*Use the [MTS] key to toggle between Page 1 and Page 2.
NOTE:
The remote control unit attached to this set does not
contain the [MTS] key. To perform the procedure (4), use
a remote control unit that contains the [MTS] key.
5.1.3 HOW TO EXIT THE SELF-DIAGNOSIS DISPLAY MODE
To Save Failure History:
Turn off the power by unplugging the AC power co rd plug when
in the self-diagnosis display mode.
To Clear (Reset) Failure History:
Turn off the power by pressing the [POWER] key on the remote
control unit when in the self-diagnosis display mode.
5.1.4 FAILURE HISTORY
Failure history can be counted up to 9 times for each item.When
the number exceeds 9, display will remain as 9. Failure history
will be stored in the memory unless it has been deleted.
NOTE:
Only SYNC (with/without sync signals) will be neither counted
nor stored.

5.1.5 POINTS TO NOTE WHEN USING THE SELF-DIAGNOSIS FEATURE
In addition to circuit failures (abnormal operation), the following cases may also be iagnosed as "Abnormal" and displayed and counted
as "NG".
(1) Temporary defective transmissions across circuits due to pulse interruptions
(2) Misalignment in the on/off timing of power for I2C bus (VCC) when turning on/off the main power.
Diagnosis may be impeded if a large number of items are displayed as "NG". As such, start self-diagnosis check only after 3 seconds
in the case of receivers and 5 seconds in the case of panels upon turning on the power. If recurrences are expecte d, ensure to clear
(reset) the failure history and record the new diagnosis reults.

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.
