PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS
IMPORTANT SAFETY NOTICE
A.C. Voltmeter
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.
0.16uF
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.
Good Earth Ground
such as the Water
Pipe, Conduit, etc.
1600 OHM
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.
Place this probe
on each exposed
metal part.

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.
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.
The exclamation point within an equilateral triangle is intended
to alert the service personnel to important safety information in
the service literature.
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.
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.
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).
Service work should be performed only after you are thoroughly familiar with
these safety checks and servicing guidelines.
Graphic symbols
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.
IMPLOSION
After the original service problem has been corrected, make a check of the
following:
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.
FIRE AND SHOCK HAZARD
1.
2.
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.
TIPS ON PROPER INSTALLATION
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.
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.
Soldering must be inspected to discover possible cold solder joints, solder
splashes, or sharp solder points. Be certain to remove all loose foreign
particles.
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.
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.
4.
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.
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.
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.
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 prevent possible exposure to x-radiation caused by excessive 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.
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.
CRT 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 shutdown 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.
HV SHUTDOWN PROCEDURE.
·After discharging the CRT, connect a high impedance-high voltage meter to the CRT anode
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).
·Access Video Menu and adjust Brightness and Contrast controls
for minimum screen luminance (beam current to 0 mA).
·Wait until the Video Menu or display disappear.
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.
·Connect a variable Resistor (1 MW) in parallel with RX3704, and
decrease slowly the resistance value until shutdown occurs.
·Measure High Voltage shutdown.

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.
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.
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.

Video input jacks). You could also leave AUX SOURCES
unblocked, and then choose allowable ratings.
PARENTAL CONTROL
This optional feature can be used to prevent (block)
unwanted programming from appearing on your TV.
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.
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.
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.
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.
Don’t forget the password, as it is the only way you can
access the PARENTAL CONTROL menu and change rating
selections or turn PARENTAL CONTROL off.
General audience and children viewer blocks can both
be programmed 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.
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 restrictions 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

GENERAL INFORMATION
Servicing the CL chassis is the same as with other Zenith
single-board chassis. If the set is dead, first check the
standby and switched voltages. If the switched voltages
do not appear, check the power “On” circuit. If the power
supply is OK and the set will turn on, the Horizontal
sweep circuit should be checked next. Is horizontal drive
available from the video processor chip? If the sweep
system does not start up, sweep-derived voltages will
not be generated.
If the sweep and high-voltage circuits are OK and video
or audio are missing, then the audio/video/tuner
circuits should be checked. If the receiver is working
but some feature is not working, check the Service Menu.
Bring up the Service menu and check to be sure that all
items are set correctly.
Check the following:
Keyboard input at IC6000 pins 7 and 8
IR input at IC6000 pin 15
Power On output at IC6000 pin 32
Check the switched voltages:
+9 VSW DC at CX3811
+14 VAUD DC for the Audio Amp at 2X3510
+8 VSW DC CX3831
SWEEP DERIVED VOLTAGES
+28 volts DC at (+) CX2114
+35 volts DC at the junction of CX3253 and DX3252
+215 volts DC at the junction of CX3208 and RX3208
+33 volts DC at the junction of RX3216 and ZD6001
MODULE-LEVEL SERVICING
The CL Chassis is Module Level repair only. Replacement
modules are available on an exchange basis.
If the CRT or Video processor IC are replaced, Black/
White tracking must be reset. Refer to the Service Menus
section of this book for Black/White tracking
adjustments.
When troubleshooting video circuits, remember that all
video travels through the Video/Audio switcher IC. A
defect in either of these IC’s can result in no video.
CRT FILAMENT
Check at pin 3 and 4 of connector CN2C5A. This should
read voltages between 6.0 and 6.4 volts AC on a true
RMS meter.
VIDEO PROCESSOR ICX2200
Check the following key operating signals and voltages:
Luminance at ICX2200 pin 43
Chroma at ICX2200 pin 45
Horizontal drive at pin 32
Vertical drive at pin 24
R Out pin 19
G Out pin 20
B Out pin 21
Serial Clock, Serial Data pins 27 and 28 respectively
VCC 9 volts pins 9, 26, 46 & 48
R in from micro (IC6000) at pin 15
G in from micro (IC6000) at pin 16
B in from micro (IC6000) at pin 17
WARNING!
DO NOT disconnect the Video output module
from the CRT when troubleshooting 32” receivers. If the video output module is removed on
these sets while power is ON, the CRT will arc
and can be permanently damaged. Also, the
technician is in danger of serious shock. There is
a termination circuit (W5101) on the CRT module to prevent this from happening.
SERVICING THE POWER SUPPLY
Check the standby voltages first:
+VM at CX3415 (usually 169.7 VDC when 120 VCA)
B+ at CX3801
Note: B+ 124 VDC for 32” & 27”, B+ 126 VDC for
25” and B+ 120 VDC for 19” & 20”.

The flyback pulse voltage from pin 6 of TX3204 (flyback
transformer) is peak detected (rectified) by the action
of the diode DX3006 and capacitor CX3003. This is from
a DC voltage appearing on CX3003 representative of the
CRT anode voltage (HV) produced by TX3204. Precision
resistors RX3013, RX3015, RX3016, and RX3022 divide
this voltage down. This lower voltage appears on the
input (QX3002 collector) of a comparator circuit formed
by RX3008, ZDX3004, QX3002, RMX3009, CX3004,
QX3001, RMX3017 and RMX3021. In the event the CRT
anode voltage becomes excessive, the comparator output
(QX3001 emitter) will go to high level, at approximately
5 volts. This signal (SHUTDOWN) is sent to pin 4 of
IC6000 (microprocessor), and used to turn off the TV
set.

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 normal horizontal
frequency. 15.75 KHz. (NTSC signal).
After discharging the CRT, connect a high impedancehigh voltage meter to the CRT anode. Turn the television
"on" and confirm a good signal is being displayed. Reduce
Brightness and Contrast setting until the procedure is
well extinguished.
Observe the anode voltage on the meter reading and

SWITCHING PROCESS
Close caption is achieved by taking a signal from the
YSW-OUT pin (31) of the video processor.
Video switching is done between the CV inputs and the
Y/C inputs. There are three CV signals to consider:
SENSING AND PRIORITIES
CAMPORT VIDEO enters at pin 7 of IC2901.
REAR VIDEO enters at pin 5 of IC2901.
IF Video enters at TV pin 12 of IC2901.
CL-Series 34 & 39 models do not have a source menu.
Software sensing the inputs based on their priorities
does switching between sources.
The camport input always has first priority, it is sensed
directly through the microprocessor. The S-Video input
has the second level. The Y/C connector does the SVideo sensing. The third level corresponds to rear video
and antenna signal (RF), they would be selected by
remote control.
These signals exit from VOUT1 (pin 11) to be processed
and returned to the switch as Y/C signals (Y-COMB and
IC2902).
The second part of the switching is between:
Y/C COMB signals enter at pins 10 and 7 of IC2902 and
Y/C EXT signals entering at pins 12 & 5 of IC2902.
The selected Y/C signals exit from pins 11 & 8 to be
sent to the video processor as main signals.

PURITY & CONVERGENCE SETUP PROCEDURE
PRELIMINARY SETUP
CONVERGENCE ADJUSTMENT
1. Allow the receiver to warm up for 15 to 20 minutes.
1. Release locking assembly.
2. Degauss the CRT.
2. Connect crosshatch generator to the receiver and
adjust static (center) convergence as follows:
3. Connect a crosshatch generator to the receiver and
“rough in” the static (center) convergence. Follow
the Convergence Procedure.
a. Adjust the 4-pole static control by moving the
two tabs separately to converge the red and blue
lines horizontally. Move the two tabs together
around the neck of the CRT (in a 45° arc) from the
top-dead-center position to converge the red and
blue lines vertically.
4. Adjust for best focus.
PURITY ADJUSTMENT
1. Purity tab positioning. Set the 2 pole purity tabs
together in the 3 or 9 o’clock positions and the 4and 6-pole purity tabs together in the 12 or 6 o’clock
positions.
b. After the 4-pole control has been adjusted to
superimpose the red and blue lines on top of one
another. Use the 6-pole static adjustment to place
the converged red and blue lines over the green
line. Move the two tabs together around the neck
of the CRT (in a 30° arc) from the top-dead-center
position to move the lines vertically. Adjusting the
two tabs separately will move the converged beam
to the left or right. Using a crosshatch generator
capable of producing individual fields, adjust the
generator to produce a red field. Use the purity
tabs to center a red stripe.
2. Move yoke to the maximum forward funnel position.
3. Next, switch the crosshatch generator to a red field.
4. Pull the yoke toward the rear of the CRT neck, keeping it centered, until a red raster is displayed.
5. If the red raster is not displayed as a pure red field,
adjust the 2-pole purity tabs until a pure field is
obtained.
6. Check for proper yoke tilt setting.

VERTICAL-TILT WEDGE ADJUSTMENT
IMPROVING CRT CORNER PURITY
The vertical lines at 6 and 12 o’clock are converged by
vertically tilting the yoke and inserting a wedge at the
top of the yoke until it is firmly seated between the CRT
glass and the horizontal coils.
CRTs that display corner purity problems even after
following the service procedures can be modified with
a picture correction kit (P/N 949-00050). The purity
can be improved by placing a picture-correction magnet
(included in the kit) on the CRT funnel. Refer to the
following modification steps and illustration to place
the magnet properly. Fully degauss the CRT before
installing correction magnets.
HORIZONTAL-TILT WEDGE ADJUSTMENT
The vertical lines at 3 o’clock and 9 o’clock are converged
by horizontally tilting the yoke and inserting a wedge.
Adjust first at 4 or 8 o’clock, whichever has the larger
space, until the wedge is firmly seated between the CRT
glass and yoke coils. Then, insert the 3rd wedge in the
remaining horizontal tilt position until it is firmly seated
between the CRT glass and yoke coils. Convergence at
the 3 and 9 o’clock should be maintained during this
operation.
When the 3 wedges are firmly installed and positioned
for acceptable convergence, lock the wedges in place
by applying a 2.5 inches long strip of tape across the
tabs of each wedge firmly against the CRT glass. The
CRT glass surface should be clean and free of dust and
other foreign material.
MODIFICATION
1. Place the magnet on the CRT funnel as shown in the
figure displayed below, in the quadrant exhibiting
impurity.
2. Rotate the magnet in place to the position shown
for best purity.
3. Place a piece of 1/2" by 2" long Fiberglass tape over
the magnet to hold it in place.
4. Degauss the CRT once magnet is in place to insure
that the magnet is not over the internal magnet
shield.
Note: If the magnet is placed over the internal
magnet shield, any apparent purity
correction will disappear after degaussing.
Reposition the correction magnet off the
internal shield and degauss again.
UNUSUAL TILT CASE
There may be some instances where the picture tube
and yoke will require vertical tilt in the opposite (up)
direction to obtain convergence. In such cases, insert
the vertical tilt wedge at the bottom (6 o’clock)
position. Follow through on the horizontal tilt
adjustment by using the 2 and 10 o’clock positions and
secure each wedge with a piece of tape, as described
above.
