SAFETY PRECAUTIONS

1. The design of this product contains special hardware, many circuits and components specially for safety purposes. For continued pro­tection, no changes should be made to the original design unless authorized in writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Service should be performed by qualified personnel only.
2. Alterations of the design or circuitry of the products should not be made. Any design alterations or additions will void the manufactur­er's warranty and will further relieve the manufacturer of responsi­bility for personal injury or property damage resulting therefrom.
3. Many electrical and mechanical parts in the products have special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in the parts list of Service manual. Electrical components having such features are
identified by shading on the schematics and by ( ) on the parts list in Service manual. The use of a substitute replacement
which does not have the same safety characteristics as the recom­mended replacement part shown in the parts list of Service manual may cause shock, fire, or other hazards.
4. Use isolation transformer when hot chassis. The chassis and any sub-chassis contained in some products are connected to one side of the AC power line. An isolation transformer of adequate capacity should be inserted between the product and the AC power supply point while performing any service on some products when the HOT chassis is exposed.
5. Don't short between the LIVE side ground and ISOLATED (NEU-
TRAL) side ground or EARTH side ground when repairing.
Some model's power circuit is partly different in the GND. The dif­ference of the GND is shown by the LIVE : ( ) side GND, the ISOLATED(NEUTRAL) : ( ) side GND and EARTH : ( ) side GND. Don't short between the LIVE side GND and ISOLATED(NEUTRAL) side GND or EARTH side GND and never measure with a measuring apparatus (oscilloscope etc.) the LIVE side GND and ISOLATED(NEUTRAL) side GND or EARTH side GND at the same time. If above note will not be kept, a fuse or any parts will be broken.
6. If any repair has been made to the chassis, it is recommended that the B1 setting should be checked or adjusted (See ADJUSTMENT OF B1 POWER SUPPLY).
7. The high voltage applied to the picture tube must conform with that specified in Service manual. Excessive high voltage can cause an increase in X-Ray emission, arcing and possible component dam­age, therefore operation under excessive high voltage conditions should be kept to a minimum, or should be prevented. If severe arcing occurs, remove the AC power immediately and determine the cause by visual inspection (incorrect installation, cracked or melted high voltage harness, poor soldering, etc.). To maintain the proper minimum level of soft X-Ray emission, components in the high voltage circuitry including the picture tube must be the exact replacements or alternatives approved by the manufacturer of the complete product.
8. Do not check high voltage by drawing an arc. Use a high voltage meter or a high voltage probe with a VTVM. Discharge the picture tube before attempting meter connection, by connecting a clip lead to the ground frame and connecting the other end of the lead through a 10kØ 2W resistor to the anode button.
9. When service is required, observe the original lead dress. Extra precaution should be given to assure correct lead dress in the high voltage circuit area. Where a short circuit has occurred, those com­ponents that indicate evidence of overheating should be replaced. Always use the manufacturer's replacement components.

AV-27D502
10. Isolation Check
(Safety for Electrical Shock Hazard)
After re-assembling the product, always perform an isolation check on the exposed metal parts of the cabinet (antenna terminals, 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 of electrical shock.
(1) Dielectric Strength Test
The isolation between the AC primary circuit and all metal parts exposed to the user, particularly any exposed metal part having a return path to the chassis should withstand a voltage of 1100V AC (r.m.s.) for a period of one second.
(. . . . Withstand a voltage of 1100V AC (r.m.s.) to an appliance rated
up to 120V, and 3000V AC (r.m.s.) to an appliance rated 200V or more, for a period of one second.) This method of test requires a test equipment not generally found in the service trade.
(2) Leakage Current Check
Plug the AC line cord directly into the AC outlet (do not use a line isolation transformer during this check.). Using a Leakage Current Tester, measure the leakage current from each exposed metal part of the cabinet, particularly any exposed metal part having a return path to the chassis, to a known good earth ground (water pipe, etc.). Any leakage current must not exceed 0.5mA AC (r.m.s.). However, in tropical area, this must not exceed 0.2mA AC (r.m.s.).
Alternate Check Method
Plug the AC line cord directly into the AC outlet (do not use a line isolation transformer during this check.). Use an AC voltmeter hav­ing 1000 ohms per volt or more sensitivity in the following manner. Connect a 1500Ø 10W resistor paralleled by a 0.15µF AC-type ca­pacitor between an exposed metal part and a known good earth ground (water pipe, etc.). Measure the AC voltage across the resis­tor with the AC voltmeter. Move the resistor connection to each ex­posed metal part, particularly any exposed metal part having a re­turn path to the chassis, and measure the AC voltage across the resistor. Now, reverse the plug in the AC outlet and repeat each measurement. Any voltage measured must not exceed 0.75V AC (r.m.s.). This corresponds to 0.5mA AC (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.).
11. High voltage hold down circuit check. After repair of the high voltage hold down circuit, this circuit shall be checked to operate correctly. See item “How to check the high voltage hold down circuit”.

5. NOTE FOR REPAIRING SERVICE
This 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 the LIVE side GND and ISOLATED(NEUTRAL) side GND at the same time with a measur­ing apparatus ( oscilloscope, etc.). 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 cir-
cuit constants may be subject to change for improvement with­out any notice.

NOTE ON USING CIRCUIT DIAGRAMS
1. SAFETY
The components identified by the symbol and shading are critical for safety. For continued safety replace safety critical components only with manufactures recommended parts.
2. SPECIFIED VOLTAGE AND WAVEFORM VALUES
The voltage and waveform values have been measured under the following conditions.
(1) Input signal : Color bar signal
(2)
Setting positions of each knob/button and variable resistor
(3) Internal resistance of tester : DC 20kØ/V (4) Oscilloscope sweeping time : H ⇒ 20µS/div
(5) Voltage values : All DC voltage values
: Original setting position when
shipped
:V 5mS/div : Others Sweeping time is
specified
9Since the voltage values of signal circuit vary to some extent ac-
cording to adjustments, use them as reference values.
3. INDICATION OF PARTS SYMBOL [EXAMPLE]

(7) Ground symbol
: LIVE side ground
: ISOLATED(NEUTRAL) side ground
: EARTH ground
: DIGITAL ground
5. NOTE FOR REPAIRING SERVICE
This 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 ( 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 cir-
cuit constants may be subject to change for improvement with­out any notice.

SAFETY PRECAUTIONS

1. The design of this product contains special hardware, many circuits and components specially for safety purposes. For continued pro­tection, no changes should be made to the original design unless authorized in writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Service should be performed by qualified personnel only.
2. Alterations of the design or circuitry of the products should not be made. Any design alterations or additions will void the manufactur­er's warranty and will further relieve the manufacturer of responsi­bility for personal injury or property damage resulting therefrom.
3. Many electrical and mechanical parts in the products have special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in the parts list of Service manual. Electrical components having such features are
identified by shading on the schematics and by ( ) on the parts list in Service manual. The use of a substitute replacement
which does not have the same safety characteristics as the recom­mended replacement part shown in the parts list of Service manual may cause shock, fire, or other hazards.
4. Use isolation transformer when hot chassis. The chassis and any sub-chassis contained in some products are connected to one side of the AC power line. An isolation transf ormer of adequate capacity should be inserted between the product and the AC power supply point while performing any ser vice on some products when the HOT chassis is exposed.
5. Don't short between the LIVE side ground and ISOLA TED (NEU-
TRAL) side ground or EARTH side ground when repairing.
Some model's power circuit is partly different in the GND. The dif­ference of the GND is shown by the LIVE : ( ) side GND, the ISOLATED(NEUTRAL) : ( ) side GND and EARTH : (
GND. Don't short between the LIVE side GND and ISOLATED(NEUTRAL) side GND or EARTH side GND and never measure with a measuring apparatus (oscilloscope etc.) the LIVE side GND and ISOLATED(NEUTRAL) side GND or EARTH side GND at the same time. If above note will not be kept, a fuse or any parts will be broken.
6. If any repair has been made to the chassis, it is recommended that the B1 setting should be checked or adjusted (See ADJUSTMENT OF B1 POWER SUPPLY).
7. The high voltage applied to the picture tube must conform with that specified in Service manual. Excessive high voltage can cause an increase in X-Ray emission, arcing and possible component dam­age, therefore operation under excessive high voltage conditions should be kept to a minimum, or should be prevented. If severe arcing occurs, remove the AC power immediately and determine the cause by visual inspection (incorrect installation, cracked or melted high voltage harness, poor soldering, etc.). To maintain the proper minimum level of soft X-Ray emission, components in the high voltage circuitry including the picture tube must be the exact replacements or alternatives approved by the manufacturer of the complete product.
8. Do not check high voltage by drawing an arc. Use a high voltage meter or a high voltage probe with a VTVM. Discharge the picture tube before attempting meter connection, by connecting a clip lead to the ground frame and connecting the other end of the lead through a 10kØ 2W resistor to the anode button.
9. When service is required, observe the original lead dress. Extra precaution should be given to assure correct lead dress in the high voltage circuit area. Where a short circuit has occurred, those com­ponents that indicate evidence of overheating should be replaced. Always use the manufacturer's replacement components.

10.Isolation Check
(Safety for Electrical Shock Hazard)
After re-assembling the product, always perform an isolation check on the exposed metal parts of the cabinet (antenna terminals, 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 of electrical shock.
(1)Dielectric Strength Test
The isolation between the AC primary circuit and all metal parts exposed to the user, particularly any exposed metal part having a return path to the chassis should withstand a voltage of 1100V AC (r.m.s.) for a period of one second.
(. . . . Withstand a v oltage of 1100V AC (r .m.s .) to an appliance rated
up to 120V, and 3000V AC (r.m.s.) to an appliance rated 200V or more, for a period of one second.) This method of test requires a test equipment not generally found in the service trade.
(2)Leakage Current Check
Plug the AC line cord directly into the AC outlet (do not use a line isolation transformer during this check.). Using a Leakage Current Tester, measure the leakage current from each exposed metal part of the cabinet, particularly any exposed metal part having a return path to the chassis, to a known good earth ground (water pipe, etc.). Any leakage current must not exceed 0.5mA AC (r.m.s.). However, in tropical area, this must not exceed 0.2mA AC (r.m.s.).
Alternate Check Method
Plug the AC line cord directly into the AC outlet (do not use a line isolation transformer during this check.). Use an AC voltmeter hav­ing 1000 ohms per volt or more sensitivity in the following manner. Connect a 1500Ø 10W resistor paralleled by a 0.15µF AC-type ca­pacitor between an exposed metal part and a known good earth ground (water pipe, etc.). Measure the A C voltage across the resis­tor with the AC voltmeter. Move the resistor connection to each ex­posed metal part, particularly any exposed metal part having a re­turn path to the chassis, and measure the AC voltage across the resistor. Now, reverse the plug in the AC outlet and repeat each measurement. Any voltage measured must not exceed 0.75V AC (r.m.s.). This corresponds to 0.5mA AC (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 .).
11. High voltage hold down circuit check. After repair of the high voltage hold down circuit, this circuit shall be checked to operate correctly. See item “How to check the high volta ge hold down circuit”.

Do not remove cover (or back ) .
No user serv i c e a ble parts inside.
R e fer servicing to qualified service pers o n n e l .
The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated “dan­gerous voltage” within the product’s enclosure that may be of sufficient magnitude to consti-
tute a risk of electric shock to persons.
The exclamation point within an equilateral tri­angle is intended to alert the user to the pres­ence of important operating and maintenance (servicing) instructions in the literature accom­panying the appliance.
WARNING: TO PREVENT FIRE OR SHOCK HAZARDS, DO NOT
EXPOSE THIS TV SET TO RAIN OR MOISTURE.
CAUTION: TO INSURE PERSONAL SAFETY, OBSERVE THE
FOLLOWING RULES REGARDING THE USE OF THIS UNIT.
1. Operate only from the power source specified on the unit.
2. Avoid damaging the ACplug and power cord .
3. Avoid Improper installation and never position the unit where good ventilation is unattainable.
4. Do not allow objects or liquid into the cabinet openings.
5. In the event of trouble, unplug the unit and call a service technician. Do not attempt to repair it yourself or remove the rear cover.
Changes or modifications not approved by JVC could void the warr a n t y. * When you don’t use this TV set for a long period of time, be sure to
disconnect both the power plug from the AC outlet and antenna for your safety.
* To prevent electric shock do not use this polarized plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.
Page 87
IMPORTANT SAFEGUARDS
CAUTION:
Please read and retain for your safety.
Electrical energy can perform many useful functions. This TV set has been engineered and manufactured to assure your personal safety. But improper use can result in poten- tial electrical shock or fire hazards. In order not to defeat the safeguards incorporated in this TV set, observe the following basic rules for its installation, use and servicing. And also follow all warnings and instructions marked on your TV set.
INSTALLATION
1 Your TV set is equipped with a polarized AC line plug (one blade of the plug is wider
than the other).
(POLARIZED-TYPE)
This safety feature allows the plug to fit into the power outlet only one way. Should you be unable to insert the plug fully into the outlet, try reversing the plug. Should it still fail to fit, contact your electrician.
2 Operate the TV set only from a power source as indicated on the TV set or refer to the
operating instructions for this information. If you are not sure of the type of power supply to your home, consult your TV set dealer or local power company. For battery operation, refer to the operating instructions.
3 Overloaded AC outlets and extension cords are dangerous, and so are frayed power
cords and broken plugs. They may result in a shock or fire hazard. Call your service technician for replacement.
4 Do not allow anything to rest on or roll over the power cord, and do not place the TV
set where power cord is subject to traffic or abuse. This may result in a shock or fire hazard.
5 Do not use this TV set near water — for example, near a bathtub, washbowl, kitchen
sink, or laundry tub, in a wet basement, or near swimming pool, etc.
6 If an outside antenna is connected to the TV set, be sure the antenna system is
grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection requirements for the grounding electrode.
Page 88
7 An outside antenna system should not be located in the vicinity of overhead power
lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.
8 TV sets are provided with ventilation openings in the cabinet to allow heat generated
during operation to be released. Therefore: — Never block the bottom ventilation slots of a portable TV set by placing it on a
bed, sofa, rug, etc.
— Never place a TV set in a “built-in” enclosure unless proper ventilation is provided. — Never cover the openings with a cloth or other material. — Never place the TV set near or over a radiator or heat register.
9 To avoid personal injury:
— Do not place a TV set on a sloping shelf unless properly secured.
— Use only a cart or stand recommended by the TV set manufacture r.
— Do not try to roll a cart with small casters across thresholds or deep pile carpets.
— Wall or shelf mounting should follow the manufacturer’s instructions, and should
use a mounting kit approved by the manufacturer.
EXAMPLE OF ANTENNA GROUNDING
AS PER NATIONAL ELECTRICAL CODE
USE
10 Caution children about dropping or pushing objects into the TV set through cabinet openings.
Some internal parts carry hazardous voltages and contact can result in a fire or electrical shock.
11 Unplug the TV set from the wall outlet before cleaning. Do not use liquid or an
aerosol cleaner.
12 Never add accessories to a TV set that has not been designed for this purpose.
Such additions may result in a hazard.
Page 89
13 For added protection of the TVset during a lightning storm or when the TV set is to be left
unattended for an extended period of time, unplug it from the wall outlet and disconnect the antenna. This will prevent damage to product due to lightning storms or power line s u rg e s .
14 A TV set and cart combination should be moved with
c a re. Quick stops, excessive force, and uneven sur­faces may cause the TVset and cart combination to o v e rt u rn .
SERVICE
15 Unplug this TV set from the wall outlet and refer servicing to qualified service per-
sonnel under the following conditions: A. When the power cord or plug is damaged or frayed. B. If liquid has been spilled into the TV set. C. If the TV set has been exposed to rain or water. D. If the TV set does not operate normally by following the operating instructions.
Adjust only those controls that are covered in the operating instructions as improper adjustment of other controls may result in damage and will often require
extensive work by a qualified technician to restore the TV set to normal operation. E. If the TV set has been dropped or damaged in any way. F. When the TV set exhibits a distinct change in performance — this indicates a
need for service.
1 6 Do not attempt to service this TV set yourself as opening or removing covers may
