PRODUCT SAFETY
IMPORTANT SAFETY NOTICE
TIPS ON PROPER INSTALLATION
This manual was prepared for use only by properly trained audio-visual service
technicians.
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.
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.
2.
3.
4.
5.
6.
Be sure that all components are positioned to avoid a possibility of
adjacent component shorts. This is especially important on items transported to and from the repair shop.
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.
Soldering must be inspected to discover possible cold solder joints,
solder splashes, or sharp solder points. Be certain to remove all loose
foreign particles.
Check for physical evidence of damage or deterioration to parts and
components, for frayed leads or damaged insulation (including the AC
cord), and replace if necessary.
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.
After reassembly 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.

ADJUSTMENT INSTRUCTIONS
These instructions are applied to all of the PDP monitor,
NP-00KB.
Because this is not a hot chassis, it is not necessary to
use an isolation transformer. However, the use of
isolation transformer will help protect test instruments.
Adjustment must be done in the correct order. If there
is no specific designation, the adjustment must be
performed at 25±5oC of temperature and 65±10% of
relative humidity.
The input voltage of the receiver must maintain
110~240V, 50/60Hz while adjusting. Operate the receiver
for about 15 minutes prior to the adjustment with 100%
white pattern (06CH). (Or white condition in HEAT-RUN
mode)
Enter into HEAT-RUN mode. Select the 2 W/B by pressing
ADJ button on Remote Control for adjustment. And press
the VOL + button. Press the VOL + button in HEAT-RUN.
(OSD display HEAT-RUN WHITE and screen display 100%
