PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS

IMPORTANT SAFETY NOTICE

This manual was prepared for use only by properly trained audio-visual service

technicians.

When servicing this product, under no circumstances should the original

design be modified or altered without permission from Zenith Electronics

Corporation. All components should be replaced only with types identical to

those in the original circuit and their physical location, wiring and lead dress

must conform to original layout upon completion of repairs.

Special components are also used to prevent x-radiation, shock and fire hazard.

These components are indicated by the letter “x” included in their component

designators and are required to maintain safe performance. No deviations are

allowed without prior approval by Zenith Electronics Corporation.

Circuit diagrams may occasionally differ from the actual circuit used. This way,

implementation of the latest safety and performance improvement changes into

the set is not delayed until the new service literature is printed.

Caution: Do not attempt to modify this product in any way. Never perform

customized installations without manufacturer’s approval. Unauthorized

modifications will not only void the warranty, but may lead to property damage

or user injury.

Service work should be performed only after you are thoroughly familiar with

these safety checks and servicing guidelines.

Graphic symbols

The exclamation point within an equilateral triangle is intended

to alert the service personnel to important safety information in

the service literature.

The lightning flash with arrowhead symbol within an equilateral

triangle is intended to alert the service personnel to the presence

of noninsulated “dangerous voltage” that may be of sufficient

magnitude to constitute a risk of electric shock.

The pictorial representation of a fuse and its rating within an

equilateral triangle is intended to convey to the service personnel

the following fuse replacement caution notice:

CAUTION: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE,

REPLACE ALL FUSES WITH THE SAME TYPE AND RATING AS MARKED

NEAR EACH FUSE.

SERVICE INFORMATION

While servicing, use an isolation transformer for protection from AC line shock.

After the original service problem has been corrected, make a check of the

following:

FIRE AND SHOCK HAZARD

1. Be sure that all components are positioned to avoid a possibility of

adjacent component shorts. This is especially important on items trans-

ported to and from the repair shop.

2. Verify that all protective devices such as insulators, barriers, covers,

shields, strain reliefs, power supply cords, and other hardware have been

reinstalled per the original design. Be sure that the safety purpose of the

polarized line plug has not been defeated.

3. Soldering must be inspected to discover possible cold solder joints, solder

splashes, or sharp solder points. Be certain to remove all loose foreign

particles.

4. Check for physical evidence of damage or deterioration to parts and compo-

nents, for frayed leads or damaged insulation (including the AC cord), and

replace if necessary.

5. No lead or component should touch a receiving tube or a resistor rated at

1 watt or more. Lead tension around protruding metal surfaces must be

avoided.

6. After re-assembly of the set, always perform an AC leakage test on all exposed

metallic parts of the cabinet (the channel selector knobs, antenna terminals,

handle and screws) to be sure that set is safe to operate without danger of

electrical shock. DO NOT USE A LINE ISOLATION TRANSFORMER DURING THIS

TEST. Use an AC voltmeter having 5000 ohms per volt or more sensitivity in

the following manner: Connect a 1500 ohm, 10 watt resistor, paralleled by

a .15 mfd 150V AC type capacitor between a known good earth ground

water pipe, conduit, etc.) and the exposed metallic parts, one at a time.

Measure the AC voltage across the combination of 1500 ohm resistor and

.15 mfd capacitor. Reverse the AC plug by using a non-polarized adaptor

and repeat AC voltage measurements for each exposed metallic part. Voltage

measured must not exceed 0.75 volts RMS. This corresponds to 0.5 milliamp

AC. Any value exceeding this limit constitutes a potential shock hazard and

must be corrected immediately.

X-RADIATION

1. Be sure procedures and instructions to all service personnel cover the

subject of x-radiation. The only potential source of x-rays in current TV

receivers is the picture tube. However, this tube does not emit x-rays when

the HV is at the factory-specified level. The proper value is given in the

applicable schematic. Operation at higher voltages may cause a failure of

the picture tube or high-voltage supply and, under certain circumstances

may produce radiation in excess of desirable levels.

2. Only factory-specified CRT anode connectors must be used.

3. It is essential that the service personnel have available an accurate and

reliable high-voltage meter.

4. When the high-voltage circuitry is operating properly, there is no possibility

of an x-radiation problem. Every time a color chassis is serviced, the

brightness should be run up and down while monitoring the high voltage

with a meter, to be certain that the high voltage does not exceed the

specified value and that it is regulating correctly.

5. When troubleshooting and making test measurements in a product with a

problem of excessively high voltage, avoid being unnecessarily close to

the picture tube and the high voltage power supply. Do not operate the

product longer than necessary to locate the cause of excessive voltage.

6. Refer to HV, B+, and shutdown adjustment procedures described in the

appropriate schematics and diagrams (where used).

IMPLOSION

1. All direct view picture tubes are equipped with an integral implosion

protection system; take care to avoid damage during installation.

2. Use only the recommended factory replacement tubes.

TIPS ON PROPER INSTALLATION

1. Never install any receiver in a closed-in recess, cubbyhole, or closely

fitting shelf space over, or close to, a heat duct, or in the path of heated

air flow.

2. Avoid conditions of high humidity such as: outdoor patio installations

where dew is a factor, near steam radiators where steam leakage is a factor,

etc.

3. Avoid placement where draperies may obstruct venting. The customer

should also avoid the use of decorative scarves or other coverings that

might obstruct ventilation.

4. Wall- and shelf-mounted installations using a commercial mounting kit

must follow the factory-approved mounting instructions. A product mounted

to a shelf or platform must retain its original feet (or the equivalent

thickness in spacers) to provide adequate air flow across the bottom. Bolts

or screws used for fasteners must not touch any parts or wiring. Perform

leakage tests on customized installations.

5. Caution customers against mounting a product on a sloping shelf or in a

tilted position, unless the receiver is properly secured.

6. A product on a roll-about cart should be stable in its mounting to the cart.

Caution the customer on the hazards of trying to roll a cart with small

casters across thresholds or deep pile carpets.

7. Caution customers against using a cart or stand that has not been listed

by Underwriters Laboratories, Inc. for use with its specific model of

television receiver or generically approved for use with TVs of the same or

larger screen size.

8. Caution customers against using extension cords. Explain that a forest of

extensions, sprouting from a single outlet, can lead to disastrous

consequences to home and family.
