IMPORTANT SAFETY PRECAUTIONSPrior 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 TV Circuit 1. Before returning an instrument to the custom-
er, always make a safety check of the entire instru-ment, including, but not limited to, the followingitems:
a. Be sure that no built-in protective devices are de-fective and have been defeated during servicing.(1) Protective shields are provided on this chassisto protect both the technician and the customer.Correctly replace all missing protective shields, in-cluding any removed for servicing convenience. (2)When reinstalling the chassis and/or other assem-bly in the cabinet, be sure to put back in place allprotective devices, including but not limited to,nonmetallic control knobs, insulating fishpapers,adjustment and compartment covers/shields, andisolation resistor/capacitor networks. Do not oper-ate this instrument or permit it to be operatedwithout all protective devices correctly in-stalled and functioning. Servicers who defeatsafety features or fail to perform safety checksmay be liable for any resulting damage.
b. Be sure that there are no cabinet openings throughwhich an adult or child might be able to insert theirfingers and contact a hazardous voltage. Suchopenings include, but are not limited to, (1) spacingbetween the picture tube and the cabinet mask, (2)excessively wide cabinet ventilation slots, and (3)an improperly fitted and/or incorrectly securedcabinet back cover.
c. Antenna Cold Check - With the instrument ACplug removed from any AC source, connect anelectrical jumper across the two AC plug prongs.Place the instrument AC switch in the on position.Connect one lead of an ohmmeter to the AC plugprongs tied together and touch the other ohmme-ter lead in turn to each tuner antenna input ex-posed terminal screw and, if applicable, to thecoaxial connector. If the measured resistance isless than 1.0 megohm or greater than 5.2 mego-hm, an abnormality exists that must be correctedbefore the instrument is returned to the customer.Repeat this test with the instrument AC switch inthe off position.
d. Leakage Current Hot Check - With the instru-ment completely reassembled, plug the AC linecord directly into a 120V AC outlet. (Do not use anisolation transformer during this test.) Use a leak-
age current tester or a metering system that com-plies with American National Standards Institute(ANSI) C101.1 Leakage Current for Appliancesand Underwriters Laboratories (UL) 1410, (50.7).With the instrument AC switch first in the on posi-tion and then in the off position, measure from aknown earth ground (metal water pipe, conduit,etc.) to all exposed metal parts of the instrument(antennas, handle brackets, metal cabinet, screwheads, metallic overlays, control shafts, etc.), es-pecially any exposed metal parts that offer an elec-trical return path to the chassis. Any currentmeasured must not exceed 0.5 milli-ampere. Re-verse the instrument power cord plug in the outletand repeat the test.
ANY MEASUREMENTS NOT WITHIN THE LIMITSSPECIFIED HEREIN INDICATE A POTENTIALSHOCK HAZARD THAT MUST BE ELIMINATEDBEFORE RETURNING THE INSTRUMENT TOTHE CUSTOMER OR BEFORE CONNECTINGTHE ANTENNA OR ACCESSORIES.
e. X-Radiation and High Voltage Limits - Becausethe picture tube is the primary potential source ofX-radiation in solid-state TV receivers, it is special-ly constructed to prohibit X-radiation emissions.For continued X-radiation protection, the replace-ment picture tube must be the same type as theoriginal. Also, because the picture tube shieldsand mounting hardware perform an X-radiationprotection function, they must be correctly in place.High voltage must be measured each time servic-

ing is performed that involves B+, horizontal de-flection or high voltage. Correct operation of theX-radiation protection circuits also must be recon-firmed each time they are serviced. (X-radiationprotection circuits also may be called "horizontaldisable" or "hold down.") Read and apply the highvoltage limits and, if the chassis is so equipped,the X-radiation protection circuit specifications giv-en on instrument labels and in the Product Safety& X-Radiation Warning note on the service datachassis schematic. High voltage is maintainedwithin specified limits by close tolerance safety-re-lated components/adjustments in the high-voltagecircuit. If high voltage exceeds specified limits,check each component specified on the chassisschematic and take corrective action.
2. Read and comply with all caution and safety-relat-ed notes on or inside the receiver cabinet, on thereceiver chassis, or on the picture tube.
3. Design Alteration Warning - Do not alter or addto the mechanical or electrical design of this TV re-ceiver. Design alterations and additions, including,but not limited to circuit modifications and the ad-dition of items such as auxiliary audio and/or videooutput connections, might alter the safety charac-teristics of this receiver and create a hazard to theuser. Any design alterations or additions will voidthe manufacturer's warranty and may make you,the servicer, responsible for personal injury orproperty damage resulting therefrom.
4. Picture Tube Implosion Protection Warning -The picture tube in this receiver employs integralimplosion protection. For continued implosion pro-tection, replace the picture tube only with one ofthe same type number. Do not remove, install, orotherwise handle the picture tube in any mannerwithout first putting on shatterproof gogglesequipped with side shields. People not soequipped must be kept safely away while picturetubes are handled. Keep the picture tube awayfrom your body. Do not handle the picture tube byits neck. Some "in-line" picture tubes are equippedwith a permanently attached deflection yoke; be-cause of potential hazard, do not try to removesuch "permanently attached" yokes from the pic-ture tube.
5. Hot Chassis Warning -
a. Some TV receiver chassis are electrically connect-ed directly to one conductor of the AC power cordand may be safety-serviced without an isolationtransformer only if the AC power plug is insertedso that the chassis is connected to the ground sideof the AC power source. To confirm that the ACpower plug is inserted correctly, with an AC volt-meter, measure between the chassis and a known
earth ground. If a voltage reading in excess of 1.0Vis obtained, remove and reinsert the AC powerplug in the opposite polarity and again measurethe voltage potential between the chassis and aknown earth ground.
b. Some TV receiver chassis normally have 85VAC(RMS) between chassis and earth ground re-gardless of the AC plug polarity. This chassis canbe safety-serviced only with an isolation transform-er inserted in the power line between the receiverand the AC power source, for both personnel andtest equipment protection.
c. Some TV receiver chassis have a secondaryground system in addition to the main chassisground. This secondary ground system is not iso-lated from the AC power line. The two ground sys-tems are electrically separated by insulationmaterial that must not be defeated or altered.
6. Observe original lead dress. Take extra care to as-sure correct lead dress in the following areas: a.near sharp edges, b. near thermally hot parts besure that leads and components do not touch ther-mally hot parts, c. the AC supply, d. high voltage,and e. antenna wiring. Always inspect in all areasfor pinched, out of place, or frayed wiring. CheckAC power cord for damage.
7. Components, parts, and/or wiring that appear tohave overheated or are otherwise damagedshould be replaced with components, parts, or wir-ing that meet original specifications. Additionally,determine the cause of overheating and/or dam-age and, if necessary, take corrective action to re-move any potential safety hazard.
8. Product Safety Notice - Some electrical and me-chanical parts have special safety-related charac-teristics which are often not evident from visualinspection, nor can the protection they give neces-sarily be obtained by replacing them with compo-nents rated for higher voltage, wattage, etc.. Partsthat have special safety characteristics are identi-fied by a ( # ) on schematics and in parts lists. Useof a substitute replacement that does not have thesame safety characteristics as the recommendedreplacement part might create shock, fire, and/orother hazards. The Product's Safety is under re-view continuously and new instructions are issuedwhenever appropriate. Prior to shipment from thefactory, our products are strictly inspected to con-firm with the recognized product safety and electri-cal codes of the countries in which they are to besold. However, in order to maintain such compli-ance, it is equally important to implement the fol-lowing precautions when a set is being serviced.
1-3-3 TD204IMP
Precautions during Servicing A. Parts identified by the ( # ) symbol are critical for
safety.
Replace only with part number specified.
B. In addition to safety, other parts and assembliesare specified for conformance with regulations ap-plying to spurious radiation. These must also bereplaced only with specified replacements.
Examples: RF converters, RF cables, noise block-ing 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 hazardouslive parts. Note especially:
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 ofwires securely about the terminals before solder-ing.
F. Observe that the wires do not contact heat produc-ing parts (heatsinks, oxide metal film resistors, fus-ible resistors, etc.)
G. Check that replaced wires do not contact sharpedged or pointed parts.
H. When a power cord has been replaced, check that5~6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repaired locations.
J. Be careful that foreign objects (screws, solderdroplets, etc.) do not remain inside the set.
K. Crimp type wire connector
When replacing the power transformer in setswhere the connections between the power cordand power transformer primary lead wires are per-formed using crimp type connectors, in order toprevent shock hazards, perform carefully and pre-cisely the following steps.
Replacement procedure
1) Remove the old connector by cutting the wires ata point close to the connector.
Important: Do not re-use a connector (discard it).
2) Strip about 15 mm of the insulation from the endsof the wires. If the wires are stranded, twist thestrands to avoid frayed conductors.
3) Align the lengths of the wires to be connected. In-sert the wires fully into the connector.
4) Use the crimping tool to crimp the metal sleeve atthe center position. Be sure to crimp fully to thecomplete closure of the tool.
L. When connecting or disconnecting the TV/DVDconnectors, first, disconnect the AC plug from ACsupply socket.
1-3-4 TD204IMP
Safety Check after ServicingExamine the area surrounding the repaired locationfor damage or deterioration. Observe that screws,parts and wires have been returned to original posi-tions. Afterwards, perform the following tests and con-firm the specified values in order to verify compliancewith safety standards.
1. Clearance DistanceWhen replacing primary circuit components, confirmspecified clearance distance (d) and (d') between sol-dered terminals, and between terminals and surround-ing metallic parts. (See Fig. 1)
Table 1: Ratings for selected area
Note: This table is unofficial and for reference only.Be sure to confirm the precise values.
2. Leakage Current TestConfirm the specified (or lower) leakage current be-tween B (earth ground, power cord plug prongs) andexternally exposed accessible parts (RF terminals,antenna terminals, video and audio input and outputterminals, microphone jacks, earphone jacks, etc.).
Measuring Method: (Power ON)

SCHEMATIC DIAGRAMS / CBA’S AND TEST POINTSStandard Notes
WarningMany electrical and mechanical parts in this chassishave special characteristics. These characteristicsoften pass unnoticed and the protection afforded bythem cannot necessarily be obtained by using replace-ment components rated for higher voltage, wattage,etc. Replacement parts that have these special safetycharacteristics are identified in this manual and itssupplements; electrical components having such fea-tures are identified by the mark " # " in the schematicdiagram and the parts list. Before replacing any ofthese components, read the parts list in this manualcarefully. The use of substitute replacement parts thatdo not have the same safety characteristics as speci-fied in the parts list may create shock, fire, or otherhazards.
Capacitor Temperature Markings
Capacitors and transistors are represented by the fol-lowing symbols.
Note:1. Do not use the part number shown on these draw-
ings for ordering. The correct part number is shownin the parts list, and may be slightly different oramended since these drawings were prepared.
2. All resistance values are indicated in ohms (K=103,
M=106).
3. Resistor wattages are 1/4W or 1/6W unless other-wise specified.
4. All capacitance values are indicated in µF
(P=10-6µF).
5. All voltages are DC voltages unless otherwisespecified.
