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.
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.

Pipe, Conduit, etc.
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.
X-RADIATION
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.
10 WATT
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).
Service work should be performed only after you are thoroughly familiar with
these safety checks and servicing guidelines.
The exclamation point within an equilateral triangle is intended
to alert the service personnel to important safety information in
the service literature.
Place this probe
on each exposed
metal part.
1.
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 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:
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
FIRE AND SHOCK HAZARD
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.
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.
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.
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.
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.
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.
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.
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.
5.
Caution customers against mounting a product on a sloping shelf or in a
tilted position, unless the receiver is properly secured.
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.
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.
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.

CH-FLAT - SAFETY
PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS
X-Radiation
To prevent possible exposure to x-radiation caused by excessive CRT
anode voltage, the CH-Flat 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 Screen Size
20"
Shutdown Circuit Operation
(Refer to Figure below)
The flyback pulse voltage from pin 6 of TX3201 (Flyback Transformer) is peak detected (rectified) by the action of diode DX3001
and capacitor C3003. This form a DC voltage appearing on C3003
representative of the CRT anode voltage (HV) produced by TX3201.
This voltage is divided down by precision resistors RX3004, RX3005,
RX3006 and RX3007. This lower voltage appears on the zener diode
ZD3000; 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 it’s 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
·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.
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).
·Connect a variable Resistor (1 MW) between ground and junction of RX3754 and RX3755, and decrease slowly the resistance
value until shutdown occurs.
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.
·Measure High Voltage shutdown.

Mode pins 1, 3, and 6 are connected to pin 4 by way of
momentary-action switches to activate indicated control function. These pins are 13 Vdc positive with respect to pin 14 when the switches are open. Loop current is 8 mA with the switches closed. Isolated audio
output is at pins 4 and 5. Mode of operation is identical to previous Zenith models using the 5-Wire Interface
with the exception of higher open circuit voltage (was
7 Vcd ) and higher loop current (was 2.5 mA).
Pins 3 and 4 support a built-in interface which allows
multiple functions on a single wire by means of serial
digital coding. Pin 3 will source up to 2 mA during the
digital "0" interval to supply operating power for the
digital encoder located in the pillow speaker. The coder
must sink a minimum of 5 mA to pin 4 during the digital
"1" interval and provide the correct serial data stream.
Pillow speakers meeting this specification are available
from independent manufacturers such as Curbell, Inc.
(Manufacturers wishing to produce compatible pillow
speakers or other products should contact Zenith Commercial Products for detailed specifications). An isolated
audio output is at pins 4 and 5.

user then opts for a package. Below is an example of
how TV channels may be grouped.

Repeat steps 2 and 3 to program another channel
bank. It is best to do ADD/DEL customizing before
doing BLANKING. ADD and DEL (not BLNK) can be
used independently for channel banks 1, 2, 3, and
4).
Note: Adding the channels VCR3 or VCR4 allows the
TV to automatically tune to broadcast band channel 3
or 4 regardless of what band type is selected. This
Sometimes only one or two channel banks may be needed.
You may leave any unused bank with the channels. However, you may want to leave at least one channel in any
unused bank. Then, if someone selects an unused bank,
that channel will assure them that the TV is functional.
Note: Some channels left over from factory testing
may still be in the channel banks if you have
not yet run Auto Program.

selected, the current volume level will be retained in
memory when the TV is turned off; at TV turn on, volume
level is automatically set to the previous or last level.

8-I. MIN VOLUME (Minimum Volume)
This function determines the minimum volume level allowable with the VOLUME (VOL) Up/Down control. In this
way, for example, someone cannot set the volume too
low to hear. The range is from 0 to 63—change values
with ADJUST. The factory default is 0, which provides full
range of volume control. It may be best to set the same
value on every TV.
NOTE: The minimum volume level cannot have a value
setting higher than in the MAX VOLUME level (described
below).

This function determines the maximum volume level allowable with the VOLUME VOL Up/Down control. In this
way, for example, someone cannot set the volume level
high enough to disturb others. The range is 0 to 63,
with 63 as the default which gives the user the full range
of volume control. Change values with ADJUST keys. It
may be best to set the same value on every TV. NOTE: The
maximum volume level cannot have a value setting lower
than the MIN VOLUME level (described previously).

Check the following:
Keyboard input at IC6000 pins 7 and 8
IR input at IC6000 pin 15
Power On output at IC6000 pin 32
KX3870 Correct relay operation.
Check the switched voltages:
+9 VSW at CX3853
GENERAL INFORMATION
Servicing the CH -Flat 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.
SWEEP DERIVED VOLTAGES
+25 volts DC at (+) CX2111
+33 volts DC at ZD1240
+215 volts DC at (+) CX3209
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.
CRT FILAMENT
Check at pin 3 and 4 of connector CN5C2. This should
read voltages between 6.0 and 6.4 volts AC on a true
RMS meter.
MODULE-LEVEL SERVICING
The CH-Flat chassis is Module Level repair only.
Replacement modules are available on an exchange basis.
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 22
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 form micro (IC6000) at pin 15
G in from micro (IC6000) at pin 16
B in from micro (IC6000) at pin 17
If the CRT or Video processor IC is 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.
SERVICING THE POWER SUPPLY
Check the standby voltages first:
VDC at CX3412 (usually 169.7 VDC when 120 VCA)
+11 VSB at CX3611
B+ at CX3850
+13V at CX3662

SERVICING (continued)
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 DX3001 and capacitor C3002. This form a DC
voltage representative of the CRT anode voltage (HV)
produced by TX3201. Precision resistors RX3006 and
RX3004, divide this voltage down. This lower voltage
appears on the zener diode ZD3000; when this voltage
exceeds by 3.5 Vdc the “zener voltage” the HV shutdown
occurs (pin 29 of ICX2200).
VERTICAL CIRCUIT
Check the following at ICX2100:
Vertical drive at pin 1.
Vertical out at pin 5.
+25 VDC at pin 7.
HORIZONTAL CIRCUIT
Check the following:
Horizontal drive to base of Q3201 predriver.
Driver transformer output at base of QX3200.
Shutdown voltage at cathode of D3002.
HIGH VOLTAGE AND X RADIATION PROTECTION
To prevent possible exposure to x-radiation caused by
excessive CRT anode voltage, the CH-FLat 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.

NOTE: Each CRT screen size has it’s 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 is deemed
necessary, it is important to use original type Zenith
components. After replacement is made, confirm proper
anode voltage using the following procedure.
IF SERVICING
VIDEO DETECTOR
If there is no viewable picture on screen, access the
Service Menu and check default settings for the following
items:
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).
5-F RF AGC should be at least 40.
19-F PIF VCO set to 63.
Tune in good off-the-air signal. Place a high-impedance
voltmeter at pin 44 of ICX2200. Adjust item PIF VCO 19F to 2.5 volts DC.
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 settings until the picture is
well extinguished.
AGC DELAY
With a strong noise-free antenna signal, adjust RF AGC
5-F to a lower setting until the signal gets noisier.
Increase the setting again for a noise-free picture.
Note: If the setting is too high (above 50) the tuner input
will overload. Under certain conditions, beats may also
appear in the picture.
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.

Brightness. Do not move Aux. B offset.
9. Return the color level control to preset.
10.Disable the factory menu (Factory Mode item 0 must
be set to 0). Select “Preset” in the Video Menu under
picture preference.
FOCUS ADJUSTMENT
1. Connect the output of a NTSC generator to the
antenna input on the receiver.
2. Select white raster pattern.
3. Push menu key of remote control to observe the OSD.
4. Adjust focus potentiometer to obtain the best focus
at letters of menu.
ADJUSTMENT OF RGB CUTOFF
NOTE: If the Main module or the CRT has been replaced, G2
must be readjusted before adjusting the RGB Cutoff.
1. Enter the Service menu to gain access to the
cutoff adjustments. (Factory mode item 00 must
be set to 1 to gain access to this adjustment).
2. Set G Gain (Green) and B Gain (Blue) registers in the
Service menu to the default setting for the screen
size as listed in the service menu. See table.
3. Set color level and contrast to minimum. Set tint to
mid range.
4. Connected the output of NTSC generator to the
antenna input of the receiver. Set the generator to
a pure white signal, chroma off.
5. Set Factory menu registers #21, #22 and #23 to
adjust cutoff controls.

PURITY & CONVERGENCE SETUP PROCEDURE
PRELIMINARY SETUP
CONVERGENCE ADJUSTMENT
1. Allow the receiver to warm up for 15 to 20 minutes.
2. Degauss the CRT.
3. Connect a crosshatch generator to the receiver and
“rough in” the static (center) convergence. Follow
the Convergence Procedure.
4. Adjust for best focus.
1. Release locking assembly.
2. Connect crosshatch generator to the receiver and
adjust static (center) convergence as follows:
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 topdead-center position to converge the red and blue
lines vertically.
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.
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.
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 . 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.
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.
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.
Note:
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.
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.
