IMPORTANT SAFETY PRECAUTIONS

Prior to shipment from the factory, our products are strictly inspected for recognized product safety and electricalcodes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equallyimportant to implement the following precautions when a set is being serviced.

Safety Precautions for LCD TV

Circuit

1. Before returning an instrument to thecustomer,always make a safety check of theentire instrument, including, but not limited to, thefollowing items:

a. Be sure that no built-in protective devices aredefective and have been defeated duringservicing. (1) Protective shields are providedon this chassis to protect both the technicianand the customer. Correctly replace all missingprotective shields, including any removed forservicing convenience. (2) When reinstallingthe chassis and/or other assembly in the

cabinet, be sure to put back in place allprotective devices, including but not limited to,nonmetallic control knobs, insulatingfishpapers, adjustment and compartmentcovers/shields, and isolation resistor/capacitornetworks. Do not operate this instrument orpermit it to be operated without allprotective devices correctly installed and

functioning. Servicers who defeat safetyfeatures or fail to perform safety checksmay be liable for any resulting damage.

b. Be sure that there are no cabinet openings

through which an adult or child might be able toinsert their fingers and contact a hazardousvoltage. Such openings include, but are notlimited to, (1) spacing between the LiquidCrystal Panel and the cabinet mask, (2)excessively wide cabinet ventilation slots, and(3) an improperly fitted and/or incorrectlysecured cabinet back cover.

c. Antenna Cold Check -With the instrument ACplug removed from any AC source, connect anelectrical jumper across the two AC plugprongs. Place the instrument AC switch in theon position. Connect one lead of an ohmmeter

to the AC plug prongs tied together and touchthe other ohmmeter lead in turn to each tunerantenna input exposed terminal screw and, ifapplicable, to the coaxial connector. If themeasured resistance is less than 1.0 megohmor greater than 5.2 megohm, an abnormalityexists that must be corrected before theinstrument is returned to the customer. Repeatthis test with the instrument AC switch in the offposition.

d. Leakage Current Hot Check -With theinstrument completely reassembled, plug the

AC line cord directly into a 120 V AC outlet. (Donot use an isolation transformer during thistest.) Use a leakage current tester or ametering system that complies with AmericanNational Standards Institute (ANSI) C101.1Leakage Current for Appliances andUnderwriters Laboratories (UL) 1410, (50.7).With the instrument AC switch first in the onposition and then in the off position, measurefrom a known earth ground (metal water pipe,conduit, etc.) to all exposed metal parts of theinstrument (antennas, handle brackets, metalcabinet, screw heads, metallic overlays, control

shafts, etc.), especially any exposed metalparts that offer an electrical return path to thechassis. Any current measured must notexceed 0.5 milli-ampere. Reverse theinstrument power cord plug in the outlet andrepeat the test.

ANY MEASUREMENTS NOT WITHIN THELIMITS SPECIFIED HEREIN INDICATE APOTENTIAL SHOCK HAZARD THAT MUST

BE ELIMINATED BEFORE RETURNING THEINSTRUMENT TO THE CUSTOMER OR

BEFORE CONNECTING THE ANTENNA ORACCESSORIES.

2. Read and comply with all caution and safety-related notes on or inside the receiver cabinet, onthe receiver chassis, or on the Liquid CrystalPanel.

3. Design Alteration Warning -Do not alter or addto the mechanical or electrical design of this TVreceiver. Design alterations and additions,including, but not limited to circuit modificationsand the addition of items such as auxiliary audioand/or video output connections, might alter thesafety characteristics of this receiver and create ahazard to the user. Any design alterations oradditions will void the manufacturer's warranty and

may make you, the servicer, responsible forpersonal injury or property damage resultingtherefrom.

4. Hot Chassis Warning -

a. Some TV receiver chassis are electricallyconnected directly to one conductor of the ACpower cord and maybe safety-serviced withoutan isolation transformer only if the AC powerplug is inserted so that the chassis isconnected to the ground side of the AC powersource. To confirm that the AC power plug isinserted correctly, with an AC voltmeter,

measure between the chassis and a knownearth ground. If a voltage reading in excess of1.0 V is obtained, remove and reinsert the ACpower plug in the opposite polarity and againmeasure the voltage potential between thechassis and a known earth ground.

b. Some TV receiver chassis normally have 85VAC(RMS) between chassis and earth groundregardless of the AC plug polarity. This chassiscan be safety-serviced only with an isolationtransformer inserted in the power line betweenthe receiver and the AC power source, for bothpersonnel and test equipment protection.

c. Some TV receiver chassis have a secondaryground system in addition to the main chassisground. This secondary ground system is notisolated from the AC power line. The twoground systems are electrically separated byinsulation material that must not be defeated oraltered.

5. Observe original lead dress. Take extra care toassure correct lead dress in the following areas: a.near sharp edges, b. near thermally hot parts-besure that leads and components do not touchthermally hot parts, c. the AC supply, d. high

voltage, and, e. antenna wiring. Always inspect inall areas for pinched, out of place, or frayed wiring.Check AC power cord for damage.

6. Components, parts, and/or wiring that appear tohave overheated or are otherwise damagedshould be replaced with components, parts, orwiring that meet original specifications.Additionally, determine the cause of overheatingand/or damage and, if necessary, take correctiveaction to remove any potential safety hazard.

7. Product Safety Notice -Some electrical andmechanical parts have special safety-relatedcharacteristics which are often not evident fromvisual inspection, nor can the protection they givenecessarily be obtained by replacing them withcomponents rated for higher voltage, wattage, etc.Parts that have special safety characteristics areidentified by a #on schematics and in parts lists.Use of a substitute replacement that does not

have the same safety characteristics as therecommended replacement part might createshock, fire, and/or other hazards. The product'ssafety is under review continuously and newinstructions are issued whenever appropriate.Prior to shipment from the factory, our productsare strictly inspected to confirm they comply withthe recognized product safety and electrical codesof the countries in which they are to be sold.However, in order to maintain such compliance, itis equally important to implement the followingprecautions when a set is being serviced.

Instructions for Handling Semi-

conductors

Electrostatic breakdown of the semi-conductors mayoccur due to a potential difference caused byelectrostatic charge during unpacking or repair work.

1. Ground for Human Body

Be sure to wear a grounding band (1 M) that isproperly grounded to remove any static electricity thatmay be charged on the body.

2. Ground for Workbench

Be sure to place a conductive sheet or copper platewith proper grounding (1 M) on the workbench orother surface, where the semi-conductors are to beplaced. Because the static electricity charge onclothing will not escape through the body groundingband, be careful to avoid contacting semi-conductorswith your clothing.

SCHEMATIC DIAGRAMS AND TEST POINTS

Standard Notes

WARNING

Many electrical and mechanical parts in this chassishave special characteristics. These characteristicsoften pass unnoticed and the protection afforded bythem cannot necessarily be obtained by usingreplacement components rated for higher voltage,wattage, etc. Replacement parts that have thesespecial safety characteristics are identified in thismanual and its supplements; electrical componentshaving such features are identified by the mark # inthe schematic diagram and the parts l ist. Beforereplacing any of these components, read the parts listin this manual carefully. The use of substitutereplacement parts that do not have the same safetycharacteristics as specified in the parts list may createshock, fire, or other hazards.

Notes:

1. Do not use the part number shown on thesedrawings for ordering. The correct part number isshown in the parts list, and may be slightlydifferent or amended since these drawings wereprepared.

2. All resistance values are indicated in ohms(K = 103, M = 106).

3. Resistor wattages are 1/4W or 1/6W unlessotherwise specified.

4. All capacitance values are indicated in F

(P = 10-6

F).5. All voltages are DC voltages unless otherwise

specified.

6. This schematic diagrams are masterized versionthat should cover the entire PL10.5 chassis models.Thus some parts in detail illustrated on thisschematic diagrams may vary depend on themodel within the PL10.5 chassis.Please refer to the parts lists for each models.

7. The Circuit Board layout illustrated on this servicemanual is the latest version for this chassis at themoment of making this service manual.

Depend on the mass production date of eachmodel, the actual layout of each Board may differslightly from this version.

Power Supply CBA Top ViewBecause a hot chassis ground is present in the power supply

circuit, an isolation transformer must be used when repairing.

Also, in order to have the ability to increase the input slowly,

when troubleshooting this type of power supply circuit,

a variable isolation transformer is required.
