SAFETY PRECAUTIONS1. The design of this product contains special hardware, many
circuits and components specially for safety purposes. Forcontinued protection, no changes should be made to the originaldesign unless authorized in writing by the manufacturer.Replacement parts must be ident ical to those used in the originalcircuits. Service should be performed by qualif ied personnelonly.
2. Alterations of the design or circuitry of the products should not be
made. Any design alterat ions or additions will void themanufacturer's warranty and will further relieve the manufacturerof responsibility for personal injury or property damage result ingtherefrom.
3. Many electrical and mechanical parts in the products have
special safety-related characteristics. T hese characteristics areoften not evident f rom visual inspection nor can the protect ionafforded by them necessarily be obtained by using replacementcomponents rated for higher voltage, wattage, etc. Replacementparts which have these special safety characterist ics areidentified in the parts list of Service manual. Electricalcomponents having su ch features are identified by shadingon the schematics and by (!!!! ) on the parts list in Servicemanual. The use of a substitute replacement which does nothave the same safety characterist ics as the recommendedreplacement part shown in the parts list of Service manual maycause shock, fire, or other hazards .
4. Do n't short between the LIVE side ground and ISOL ATED
(NEUTRAL) side ground or EARTH side ground whenrepairing.Some model's power circuit is partly different in the GND. Thedifference of the GND is shown by the LIVE : (") side GND, theISOLATED(NEUTRAL) : (#) side GND and EARTH : ($) sideGND. Don't short between the LIVE side GND andISOLATED(NEUTRAL) side GND or EARTH side GND andnever measure with a measuring apparatus (oscilloscope etc.)the LIVE side GND and ISOLATED(NEUTRAL) side GND orEARTH side GND at the same time.If above note will not be kept, a fuse or any parts will be broken.
5. If any repair has been made to the chassis, it is recommended
that the B1 setting should be checked or adjusted (SeeADJUSTMENT OF B1 POWER SUPPLY).
6. The high voltage applied to the picture tube must conform with
that specified in Service manual. Excessive high voltage cancause an increase in X-Ray emission, arcing and possiblecomponent damage, therefore operation under excessive highvoltage conditions should be kept to a minimum, or should beprevented. If severe arc ing occurs, remove the AC powerimmediately and determine the cause by visual inspect ion(incorrect installat ion, cracked or melted high voltage harness,poor soldering, etc.). To maintain the proper minimum level ofsoft X-Ray emission, components in the high voltage circuitryincluding the picture tube must be the exact replacements oralternat ives approved by the manufacturer of the completeproduct.
7. Do not check high voltage by drawing an arc. Use a high voltage
meter or a high voltage probe with a VTVM. Discharge thepicture tube before attempting meter connection, by connect inga clip lead to the ground frame and connecting the other end ofthe lead through a 10kΩ 2W resistor to the anode button.
8. When service is required, observe the original lead dress. Extra
precaut ion should be given to assure correct lead dress in thehigh voltage circuit area. W here a short circuit has occurred,those components that indicate evidence of overheating shouldbe replaced. Always use the manufacturer's replacementcomponents.
9. Isolation Check(Safety for Electrical Shock Hazard)After re-assembling the product, always perform an isolat ioncheck on the exposed metal parts of the cabinet (antennaterminals, video/audio input and output terminals, Control knobs,metal cabinet, screwheads, earphone jack, control shafts, etc.)to be sure the product is safe to operate without danger ofelectrical shock.
(1) Dielectric Strength TestThe isolation between the AC primary circuit and all metal partsexposed to the user, particularly any exposed metal part having areturn path to the chass is should withs tand a voltage of 3000VAC (r.m.s.) for a period of one second.(. . . . Withstand a voltage of 1100V AC (r.m.s.) to an appliancerated up to 120V, and 3000V AC (r.m.s.) to an appliance rated200V or more, for a period of one second.)This method of test requires a test equipment not generally foundin the service trade.
(2) Leakage Current CheckPlug the AC line cord direct ly into the AC outlet (do not use a lineisolation transformer during this check.). Using a " LeakageCurrent Tester", measure the leakage current f rom each exposedmetal part of the cabinet, part icularly any exposed metal parthaving a return path to the chassis , to a known good earthground (water pipe, etc.). Any leakage current must not exceed0.5mA AC (r.m.s.).However, in tropical area, this must not exceed 0.2mA AC(r.m.s.)."""" Alternate Check MethodPlug the AC line cord direct ly into the AC outlet (do not use a lineisolation transformer during this check.). Use an AC voltmeterhaving 1000 ohms per volt or more sens it ivity in the followingmanner. Connec t a 1500Ω 10W res istor paralleled by a 0.15µFAC-type capacitor between an exposed metal part and a knowngood earth ground (water pipe, etc.). Measure the AC voltageacross the res istor with the AC voltmeter. Move the resistorconnec tion to each exposed metal part, part icularly any exposedmetal part having a return path to the chassis, and measure theAC voltage ac ross the res istor. Now, reverse the plug in the ACoutlet and repeat each measurement. Any voltage measuredmust not exceed 0.75V AC (r.m.s.). This corresponds to 0.5mAAC (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.).

5.NOTE FOR REPAIRING SERVICEThis 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.
NOTEDue 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.
