PRODUCT SAFETY

IMPORTANT SAFETY NOTICE

This manual was prepared for use only by properly trained audiovisual 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. If any

fuse (or Fusible Resistor) in this TV receiver is blown, replace it only with the

factory specified fuse type and rating. When replacing a high wattage resistor

(Oxide Metal Film Resistor, over 1W), keep the resistor 10mm away from PCB.

Always keep wires away from high voltage or high temperature parts.

Special components are also used to prevent 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. Service work

should be performed only after you are thoroughly familiar with these safety

checks and servicing guidelines.

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.

GENERAL GUIDANCE

An lsolation Transformer should always be used during the servicing

of a receiver whose chassis is not isolated from the AC power line. Use a

transformer of adequate power rating to protect against personal injury from

electrical shocks. It will also protect the receiver and its components from being

damaged by accidental shorts of the circuitry that may be inadvertently

introduced during the service operation.

Before returning the receiver to the customer, always perform an AC leakage

current check on the exposed metallic parts of the cabinet, such as antennas,

terminals, etc., to be sure the set is safe to operate

without damage of electrical shock.

LEAKAGE CURRENT COLD CHECK

(ANTENNA COLD CHECK)

With the instrument’s AC plug removed from AC source, connect an electrical

jumper across the two AC plug prongs. Place the AC switch in the on position,

connect one lead of ohm-meter to the AC plug prongs tied together, and touch

other ohm-meter lead in turn to each exposed metallic parts such as antenna

terminals, phone jacks, etc. If the exposed metallic part has a return path to the

chassis, the measured resistance should be between 1MΩ and 5.2MΩ. When

the exposed metal has no return path to the chassis the reading must be

infinite. Any other abnormality that exists must be corrected before

the receiver is returned to the customer.

ELECTROSTATICALLY SENSITIVE DEVICES

Some semiconductor (solid-state) devices can be damaged easily by static

electricity. Such components commonly are called Electrostatically Sensitive

(ES) Devices. Examples of typical ES devices are integrated circuits and some

field-effect transistors and semiconductor “chip” components. The following

techniques should be used to help reduce the incidence of component damage

caused by static electricity.

1. Immediately before handling any semiconductor component or

semiconductor-equipped assembly, drain off any electrostatic charge on the

body by touching a known earth ground. Alternatively, obtain and wear a

commercially available discharging wrist strap device, which should be

removed for potential shock reasons prior to applying power to the unit under

test.

2. After removing an electrical assembly equipped with ES devices, place the

assembly on a conductive surface such as an ESD mat, to prevent

electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices

not classified as “anti-static” can generate electrical charges sufficient to

damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical charge

sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until

immediately before you are ready to install it. (Most replacement ES devices

are packaged with leads electrically shorted together by conductive foam,

aluminum foil, or comparable conductive material.)

7. Immediately before removing the protective material from the leads of a

replacement ES device, touch the protective material to the chassis or circuit

assembly into which the device will be installed.

Caution: Be sure no power is applied to the chassis or circuit, and observe

all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES

devices. (Otherwise, seemingly harmless motion, such as the brushing

together of your clothing or the lifting of your foot from a carpeted floor, can

generate static electricity sufficient to damage an ES device.)
