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

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 transported 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
components, 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
.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 .15mfd
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.

Pipe, Conduit, etc.

metal part.
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.

PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS
X-Radiation
To preven t possible exposure to x-radi ation caused by ex cessive CRT
anode voltage, the CL chassis incorporate a “High Voltage Shutdown” circuit. This circuit senses the level of a flyback pulse from the
“Flyback Transformer” representative of the actual high voltage on
the CRT anode. When this level exceeds a predetermined voltage, the
circuit shuts down the TV set, preventing further generation of anode
voltage.
Shutdown Circuit Operation
(Refer to Figure below)
The flyback pulse voltage from pin 6 of TX3204 (Flyback Transformer)
is peak detected (rectified) by the action of diode DX3006 and capacitor CX3003. This forms a DC voltage appearing on CX3003 representative of the CRT anode voltage (HV) produced by TX3204. This
voltage is divided down by precision resistors RX3013, RX3015,
RX3016 and RX3022. This lower voltage appears on the zener diode
ZDX3004; when this voltage exceeds by 3.5 Vdc the “zener voltage”
the HV shutdown occurs (pin 29 of ICX2200).
CRT Anode High Voltage Measurement Procedure
Each CRT screen size has its own safe operating anode and shut-
down voltage. Critical safety component (designated with an ‘X’ in
the component designator) are designed to operate the CRT at a
safe operating anode voltage and provide proper shutdown thresholds. If replacement of any of these components are deemed
necessary, it is important to use original type Zenith components. After replacement is made, confirm proper anode voltage
using the following procedure.
Measurement of the CRT anode voltage must be performed using a
high impedance-high voltage meter, with no raster on the screen,
and operating at nominal horizontal frequency, 15.75 Khz (NTSC
signal).
After discharging the CRT, connect a high impedance-high voltage
meter to the CRT anode. Turn the television ‘on’ and confirm a good
signal is being displayed. Reduce Brightness and Contrast settings
until the picture is well extinguished.
Observe the anode voltage meter reading and compare with the
table below for the proper CRT screen size. If the voltage reading is
higher than the maximum, verify circuit component values and
proper operation.

INTERFACES
CAMPORT
Some models have video and right/left audio input jacks
at the front of the receiver. These jacks can be used to
view videotapes from a VCR or Camcorder. When the
video cable is plugged into the jack, the shorting
jumper J1 opens, placing a high at pin 10 of the IC6000
microprocessor. This switches the TV into the auxiliary
mode. As long as the cables are attached, the TV set
will be locked in auxiliary mode. Use of a remote control
or buttons on the front of the set will not permit
switching into tuner mode until the video cable is
disconnected.
SUPERPORT - MPI
Zenith Commercial Product receivers are now being
adapted to interact with other equipment. Prime
examples of this can be found in Lodging and Health
Care situations where the set is controlled from the
main office.
All this is made possible by the new technology that is
being built into these receivers. The SuperPort and
Multiple Protocol Interface (MPI) jack and associated
circuitry allow remote control of the set.
MULTIPLE PROTOCOL INTERFACE
Television functions and features are controlled by the
communication of commands and status information
through a SuperPort by the MPI interface.
EBC (EDGE BOARD CONNECTOR)
Allows easy access for removing/installing accessory
modules providing a rail mounted slide-through card.
These cards might contain one of the above features.

QUICKSET II PROGRAMMER
The Quick Set II programmer LT2000 & LT2002 allows
custom setup and programming information to be quickly
copied from a master TV into multiple television sets.
Once learned from the master, setup data is retained in
the LT2002 for future use and recall.
When using the LT2002 , operation will be easier if the
TV is connected to a good quality signal and is displaying
a stable picture . To oper ate the L T2002, use the indicated
keys on an installer’s remote or user’s remote, or the front
panel keys on the TV receiver.
SETUP
Begin the programming process by setting up a master
TV set using one of the installer’s remotes or an MBR
remote. Follow the instructions in the operating guide
for the specific TV model. Remember to set all features
that will be customized including the channel scan list,
channel labels, and installer menu setups.
Next connect the LT2002 to the master TV set using
the cable provided with the programmer. Connect the
cable between the MPI jack on the TV and the
programmer. The TV set automatically activates the
programmer.
Once connected, check the “Status Indicator” LED on
the programmer. If the indicator is green and flashing
(a double-blink “heartbeat” pattern), proceed to the
next step.
NOTE: A slowly flashing green light indicates there is
a problem with the communications between
TV and programmer. In this case, check for
damaged cable, poor contacts, or other
connection problems. If the status indicator is
red, the programmer batteries are low.
If communications are good, the sign-on screen will be
displayed on the TV screen as shown on the quick setup
instructions. If the intention is to set the TV’s or
programmer’s real-time clocks, and not the clone clock
or TV clock time settings, then press a key to proceed
to the main clone menu.
If a previously stored TV setup is in a particular clone

PARENTAL CONTROL
This optional feature can be used to prevent (block)
unwanted programming from appearing on your TV.
PARENTAL CONTROL offers the user a wide variety of
options and settings that restrict or block programming
that can appear on the TV. PARENTAL CONTROL allows
users the capability of defining which program ratings
they consider acceptable to younger or more sensitive
viewers.
PARENTAL CONTROL can be preset and turned on or off
by a user who specifies the 4 number password. The
number of hours blocked must also be specified.
General audience and children viewer blocks can both
be programm ed into the TV’s memory. Viewer ratings are
specified for both the TV industry and the motion picture industry; both rating systems can be used. The ratings are based mainly on children’s ages.

OVERVIEW
To en sure complete coverag e for all TV program s (movies
and regular TV shows), choose ratings from the Motion
Picture Association of America (MPAA) Rating System
chart and the TV Parental Guidelines Rating System chart
(both shown in next page). Use the AGE BLOCK option
for General Audiences and for Children. You can also
add additional restrictions from the CONTENT BLOCK
menu.
Things to Consider before Setting Up Parental Control:
Determine which ratings you consider acceptable for
viewing. (For example, if you choose TV-PG, all of the
more restrictive ratings will be blocked automatically:
the viewer will not be able to see TV-PG, TV-14, or
TV-MA rated programming.)
Select whether auxiliary video sources will be blocked
TO BLOCK
in the AUX SOURCES block option. (Blocks signals from
VCRs, DVD players, etc. connected to the TV Audio/
Video input jacks). You could also leave AUX SOURCES
unblocked, and then choose allowable ratings.
In the CONTENT BLK option, you can block program
Content based on individual parameters such as Strong
Dialog, Bad Language, Sex Scenes, Violence Scenes, or
Fantasy Violence Scenes.
You can set PARENTAL CONTROL to be active in the SET
HOURS option for up to 12 hours. Use the number keys
on the remote to select a secret password in the SET
PASSWORD option.
Don’t forget the password, as it is the only way you can
access the PARENTAL CONTROL menu and change ratin g
selections or turn PARENTAL CONTROL off.
If you do not want PARENTAL CONTROL to be active all
the time, you can turn it on or off with the LOCK ON/
OFF option.
Notes:
You can set different PARENTAL CONTROL viewing re-
strictions for general audiences and for children - both can be active at the same time.
Simply specifying one content block such as Sex Scenes,
will not automatically block another type of content
in the programs from appearing.
Even if you choose to leave the AUX INPUTS unblocked,
the ratings you specify will automatically restrict the
programming that appears from the video sources.
You cannot disable PARENTAL CONTROL by disconnecting
the TV from power. Block hours will automatically reset
to the original block time setting specified if power
is disconnected.
To reset the password, use the installer’s remote
control to deactivate the V-Chip in the Installer’s menu
(#21). Exit out of the Installer’s Menu after
deactivating the Parental Control. Then enter back in
and reactivate the V-Chip.
With the PARENTAL CONTROL menu on-screen, use the
Up Arrow to choose an option, such as CONTENT BLOCK.
Use the Left/Right arrow to show the CONTENT BLOCK
menu, to adjust or set the rating for an option.
To block sex scenes, for example, use the “TV-PG and
above” setting. To block dialog, use LEFT/RIGHT ADJ
arrows to select among UNBLOCKED, TV-PG and above,
or TV-14. (See the Ratings Charts for rating meanings.)
After you have selected and adjusted the PARENTAL
CONTROL menu options to your preferences:
- Set the number of hours Parental Control will be on.
- Set a 4 number password.
- Set the Lock On/Off option to either on or off.
