PRODUCT SAFETY
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.
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.
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.
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.
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.)
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.
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: 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.
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.)
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.
REGULATORY INFORMATION
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a residential
installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio
communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures: Reorient or relocate the receiving antenna; Increase the separation between the equipment and receiver; Connect
the equipment into an outlet on a circuit different from that to
which the receiver is connected; Consult the dealer or an experienced radio/TV technician for help.
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 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.
The responsible party for this device’s compliance is:
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.

COMPUTER CONNECTION
Set the monitor output resolution on the PC before
connecting to the TV (see table). Connect the TV to the
PC with a PC cable (VGA cable). Connect the PC audio
output to the TV’s PC SOUND input.
After setup, be sure to set TV to PC source. Turn on the
PC/Computer. Turn the TV on and use tv/video button
to select RGB-PC as the source.
The TV has been pre-adjusted to use XGA1024x768, 60Hz
format. If possible, use one of the XGA formats to obtain
the best image quality for your TV/LCD monitor. If set
up under other resolutions, a distorted picture may
appear on the screen. If set to Vertical frequency 85Hz,
some noise can be seen when PIP is on. In this case, set
the Vertical frequency to 60Hz. If the message “OUT OF
RANGE” appears on the screen, adjust the PC output to a
format listed in the chart.
