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.

1-2-1 L0604IMP

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.

7 Product 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.

1-2-3 L0604IMP

Safety Check after Servicing

Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires have been returned to original positions. Afterwards, perform th e fol lo wing tes ts and c on firm the specified values in orde r to verify comp liance with safety standards.

1. Clearance Distance

When replacing primary circuit components, confirm specified clearance d istance (d) a nd (d') betwee n soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)
