IMPORTANT SAFETY PRECAUTIONS
Prior to shipment from the fact ory, our products are stri ctly insp ected for recogni zed pr oduct sa fety and elec trical
codes of the countries in which they are to be sold. Howev er, in order to ma intain such c ompliance, it is equally
important to implement the following precautions when a set is being serviced.
Safety Precautions fo r M onitor C ircuit
1. Before returning an instrum ent t o the c ustom -
er, always make a safety check of the entire instru-
ment, including, but not limited to, the following
items:
a. Be sure that no built-in protec tive devic es are de -
fective and have b een defeated during servicing.
(1) Protective shields are provided on this chassis
to protect both the technician an d the customer.
Correctly replace all missing protective shields, including any removed for servicing convenience. (2)
When reinstalling the chassis and/or other assembly in the cabinet, be su re to put back in p lace all
protective devices, including but not limited to,
nonmetallic control knobs, insulating fishpapers,
adjustment and compartment cove rs/shields, and
isolation resistor/capacitor networks. Do not oper-
ate this instrument or permit it to be operated
without all protective devices correctly installed and functioning. Servicers who defeat
safety features or fail to perform safety checks
may be liable for any resulting damage.
b. Be sure that there are no cabinet openings through
which an adult or child might be able to insert their
fingers and contact a hazardous voltage. Such
openings include, but are not limited to, (1) excessively wide cabinet ventilation slots, and (2) an improperly fitted and/or incorrectly secured cabinet
back cover.
c. Leakage Current Cold Check - With the instru-
ment AC plug removed from any AC s ource, con nect an electrical jumper across the two AC plug
prongs. Place the in strument AC swi tch in the on
position. Connect one lead of an oh mmeter to the
AC plug prongs tied together and touch the other
ohmmeter lead in tu rn to each exposed metallic
cabinet part. If the measured resistance is less
than 1.0 megohm or greater than 5.2 megohm, an
abnormality exists that must be corrected before
the instrument is returned to the customer. Repeat
this test with the instrument AC switch in the off position.
d. Leakage Current Hot Check - With the instru-
ment completely reassembled, plug the AC line
cord directly into a 120V AC outlet. (Do not use an
isolation transformer d uring thi s test.) Use a leakage current tester or a metering system that complies with American National Standards Institute
(ANSI) C101.1 Leakage Current for Appliances.
With the instrument AC switc h first in the on posi tion and then in the o ff position, measure from a
known earth ground (metal water pipe, conduit,
etc.) to all exposed metal parts of the instrument
(antennas, handle br ackets, metal cabi net, screw
heads, metallic overlay s, control shafts, etc.), es pecially any exposed metal parts that offer an electrical return path to the chassis. Any current
measured must not exceed 0.75 milli-ampere. Reverse the instrument power cord plug in the outlet
and repeat the test.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
SPECIFIED HEREIN INDICATE A POTENTIAL
SHOCK HAZARD THAT MUST BE ELIMINATED
BEFORE RETURNING THE INSTRUMENT TO
THE CUSTOMER OR BEFORE CONNECTING
THE ANTENNA OR AC CES SORI ES.
2. Read and comply with all caution and safety-related notes on or insid e the cabi net, or on the chassis,
3. Design Alteration Warning - Do not alter or add
to the mechanical or electrical design of th is mon itor. Design alterations and additions, including,
but not limited to circuit mod ifications and the addition of items such as auxiliary audio and/or video
output connections, might a lter the sa fety charac teristics of this receiver and create a hazard to the
user. Any design alterations or additions will void
the manufacturer's warrant y and may make you,
the servicer, responsible for personal injury or
property damage resulting therefrom.
4. Hot Chassis Warning -
a. Some monitor chassi s are electrically connected
directly to one conductor of the AC power cord and
maybe safety-servi ced without an isolati on transformer only if the AC power plug is inserted so that
the chassis is con nec ted to the ground side of the
AC power source . To confirm that the A C power
plug is inserted correctly, with an AC voltmeter,
measure between the chas sis and a known ear th
ground. If a voltage read ing in excess of 1.0V is
obtained, remove and reinsert t he AC power plug
in the opposite polarity and again measure the
voltage potential between the chassis and a
known earth ground.
1-2-1L0604IMP
Page 7
b. Some monitor chassis normally have 85V
AC(RMS) between chassi s and earth ground regardless of the AC p lug pol arity. This chass is can
be safety-serviced only with an isolation transformer inserted in the p ower lin e betwee n the r ecei ver
and the AC power so urce, for both p erso nnel a nd
test equipment protection.
c. Some monitor chassis have a secondary ground
system in addition to the main chassis ground.
This secondary ground system is not isolated from
the AC power line. The two ground systems are
electrically separated by insulation material that
must not be defeated or altered.
5. Observe orig inal lead dre ss. Take extra ca re to assure correct lead dress in the following areas:a.
near sharp edges,b. near thermally hot parts-be
sure that leads and components do not touch thermally hot parts,c. th e AC supply,d. high voltage,
and,e. antenna wiring. Always inspect in all ar eas
for pinched, out of plac e, or frayed wiring. Ch eck
AC power cord for damage.
6. Components, parts, and/or wiring that appear to
have overheated or are otherwise damaged
should be replaced with components, parts, or wiring that meet origina l specifications. Additionally,
determine the cause of ov erheating and/or damage and, if necessary, take corrective action to remove any potential safety hazard.
7Product Safety Notice - Some electrical and me-
chanical parts have sp ecial safety -relate d char acteristics which are often not evident from visual
inspection, nor can the protection they give necessarily be obtain ed by replac ing them wi th components rated for higher voltage, wattage, etc.. Parts
that have special safet y characte ristic s are ide ntified by a ( # ) on schematics and in parts lists. Use
of a substitute replacement that does not have the
same safety charac teristics as the recommend ed
replacement part might crea te shock, fire, and/or
other hazards. The product's safety is under review continuously and new instructions are issued
whenever appropriate . Prior to shipme nt from the
factory, our produc ts are strict ly ins pected to con firm they comply with the recognized product safety and electrical code s of the countries in which
they are to be sold. However , in order to maintai n
such compliance, it is equally important to implement the following precautions when a set is being
serviced.
General Caution of Plasma Display
1. Since the Panel module and front filter are made of
glass, sufficient care shall be taken when handling
the broken module and filter in order to avoid injury.
2. If necessary to replace Panel module, this work
must be started after the panel module and the
AC/DC Power supply becomes sufficiently cool.
3. Special care must be taken with the display area to
avoid damaging its surface.
4. The Panel Module sha ll not be touched wit h bare
hands to protect its surface from stains.
5. It is recommended to use clean soft gloves during
the replacing work of the Panel module in order to
protect, not only the display area of the panel module but also the serviceman.
6. The Chip Tube of the panel module (located upper
left of the back of the panel modu le) and flexible
cables connecting Pane l glasses to the drive circuitry Printed Wiring Boards (P.W.B.) are very
weak, so sufficient c are must be taken t o prevent
breaking or cutting any of these. I f the Chip Tube
breaks the panel mo dul e wi ll ne ve r w ork, re pla ce ment for a new plasma panel module will be needed.
7. Signal, power supply P.W.B.’s and PDP driving circuits P.W.B.’s are assembled o n the rear side of
the PDP module, take special care with this fragile
circuitry; particularly, Flexible Printed Circuits
bonded to surrounding edges of the glass panel.
They are not strong enough to withstand harsh
outer mechanical forces. Avoid tou ching th e flexible printed circuits by not only your hands, but also
tools, chassis, or any oth er obj ec t. E xtre me bend ing of the connectors must be avoided too. In case
the flexible printed c ircuits are damage d, the corresponding addres sed portions of the screen will
not be lit and exchange of a glass panel will be required.

PDP Module Handling
Precautions during Servicing
When there is need to rep lace a brok en PDP m odule
which is the displaying device from the Plasma display
unit, consider the following:
1. When carrying the PDP module, two persons
should stand at both shorter-edge sides of the
glass-panel and transport it with their palms. Avoid
touching the Flexible Prin ted Circuits or the chip
tube on the corner of the glass-panel. Handle only
by the surface of the glass panel.
2. When carrying PDP module, watch surrounding
objects, such as tables, and also do not carry it
alone since it may be dangerous and it will be damaged due to excessive stress to the module (glasspanel).
3. Please do not stand the m odule with the edge of
the glass-panel on the table since this might result
in damage to the glass-pa nel and /or flex ible printed circuits due to exces sive stress to the modul e
(glass-panel).
A. Parts identified by th e ( # ) symbol are critical for
safety.
Replace only with part number specified.
B. In addition to safety, other parts and assemblies
are specified for conformance with regulations applying to spurious radiati on. These must also be
replaced only with specified replacements.
Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.
C. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
D. Use specified insulating materials for hazardous
live parts. Note especiall y:
1) Insulation Tape
2) PVC tubing
3) Spacers
4) Insulators for transistors.
E. When replacing AC primary side components
(transformers, power cord, etc.), wrap ends of
wires securely about the terminals before solder ing.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.)
G. Check that replaced wires do not contact sharp
edged or pointed parts.
H. Also check areas surrounding repaired locations.
I.Use care that foreign objects (screws, solder drop-
lets, etc.) do not remain inside the set.
J. When connecting or disconnecting the internal
connectors, first, discon nect the AC plug from the
AC supply outlet.

SAFETY PRECAUTIONS
PDP Module is a displa y devi ce to be div ided in to a Panel part and a Drive part. The Panel part con sis ts of Electrodes, Phosphor, various dielectrics and gas, and the Drive part includes electronic circuitry and PCB.
When using/handling this PDP Module, pay attention to the below warning and cautions.
Warning!
Indicates a hazard that may lead to death or injury if the warning is ignored and the product is handled incorrectly.
Caution!
Indicates a haza rd that can l ead to inj ury or dam age to proper ty if the ca ution is ignored and the produ ct is han dled incorrectly.
1. WARNING
(1) Do not supply a voltage highe r than that specified to this product. This may dam age the product and may
cause a fire.
(2) Do not use this product in locations where the humidity is extremely high, where it may be splashed with wa-
ter, or where flammable materials surround it.
Do not install or use the product in a location that does no satisfy the specified environmental conditions. This
may damage the product and may cause a fire.
(3) If a foreign substance (such as water, metal, or liquid) gets inside the product, immediately turn off the power.
Continuing to use the product, it is may cause fire or electric shock.
(4) If the product emits smoke, and abnormal smell, or makes an abnormal sound, immediately turn off the power.
Continuing to use the product, it may cause fire or electric shock.
(5) Do not disconnect or connect the connector while power to the product is on. It takes some time for the voltage
to drop to a sufficiently low level after the power has been turned off.
Confirm that the voltage has dropped to a safe level before disconnecting or connecting the connector.
(6) Do not pull out or insert the power cable from/to an outlet with wet hands. It may cause electric shock.
(7) Do not damage or modify the power cable. It may cause fire or electric shock.
(8) If the po wer cab le is dama ged, or if the co nnecto r is l oose , do no t use the pr oduct: o the rwise, t his can lead
to fire or electric shock.
(9) If the power connecto r or the connec tor of t he power c able bec omes dir ty or dusty , wipe i t with a dry cl oth.
Otherwise, this can lead to fire.
(10) P DP Module uses a high voltage (Ma x.450V dc). Keep the cautions co ncerning electric shock and do not
touch the Device circuitry when handling the PDP Unit. And because the capacitor of the Device circuitry may
remain charged at the moment of Power OFF, standing by for 1 minute is required in order to touch the Device
circuitry.
2. CAUTIONS
(1) Do not place this product in a location that is subject to heavy vibration, or on an unstable surface such as an
inclined surface. The product may fall off or fall over, causing injuries.
(2) Before disconnecting cable from the product, be sure to turn off the power. Be sure to hold the connector when
disconnecting cables. Pulling a cable with excessive force may cause the core of the cable to be exposed or
break the cable, and this can lead to fire or electric shock.
(3) This product should be moved by two or more persons. If one person attempts to carry this product alone, he/
she may be injured.
(4) This prod uct contai ns glass . The g lass may break, causing injuries , if sh ock, v ibration, h eat, o r distor tion is
applied to the product.

(5) The temperature of the glass of the display may rise to 80°C or more depending on the conditions of use.
If you touch the glass inadvertently, you may be burned.
(6) If glass sur face of the display break s or is scr atched, do not touch the b roken pie ces or the scratches with
bare hands. You may be injured.
(7) PDP Module requ ires to be handled with care not to be touc hed with metal or hard materia ls, and must not
be stressed by heat or mechanical impact.
(8) There are some exp osed components on the rear panel of t his product. Touc hing these components may
cause an electric shock.
(9) When moving the product, be sure to turn off the power and disconnect all the cables. While moving the prod-
uct, watch your step. The product may be dropped or all, leading to injuries of electric shock.
(10) In order to protect static electricity due to C-MOS circuitry of the Drive part, wear a wrist band to protect static
electricity when handling.
(11) If cleaning the Panel, wipe it with a soft cloth moistened with water or a neutral detergent and squeezed, being
careful not to touch the connector part of the Panel. And don’t use chemical materials like thinner or benzene.
(12) If this product is use d as a displ ay boa rd to dis play a st atic im age, “ image stic kin g” occur s. This means that
the luminance of areas of the dis pl ay that remain lit for a long time d ro ps com par ed with lum ina nce of ar e as
that are lit for a shorter time, causing uneven luminance across the display.
The degree to which this occurs is in proportion to the luminance at which the display is used. To prevent this
phenomenon, ther efore, av oid static im ages as mu ch a s poss ible and d esign y our system so that i t is us ed
at a low luminance, by reducing signal level difference between bright area and less bright area through signal
processing.
(13) Because PDP Modul e emits heat from the Glass P anel par t and the Drive circui try, the env ironmen tal tem-
perature must not be over 40°C.
The temperature of the Glass Panel part is especially high owing to heat from internal Drive circuitry. And be-
cause the PDP Module is driven by high voltage, it must avoid conductive materials.
(14) If inserting components or circuit board in ord er to repair, be sure to fix a lead line to the c onnector before
soldering.
(15) If inserting high-power resis tor (m etal -oxide film r esi stor or metal film r esi stor) i n ord er to re pair, inse rt it as
10mm away as from a board.
(16) During repairs, high voltage or high temperature components must be put away from a lead line.
