PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS
i
IMPORTANT SAFETY NOTICE
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.
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.

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 trans-
ported 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 compo-
nents, 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
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.
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 prevent possible exposure to radiation caused by excessive
CRT Anode voltage, the CS Chassis incorporates a “High Volt-
age Shutdown” circuit. This circuit senses the level of flyback
pulse from the “Flyback Transformer” representative of the
actual high voltage on the CRT anode. When this level ex-
ceeds a predetermined voltage, the circuit shuts down the
horizontal drive, preventing further generation of anode volt-
age. In this condition, the horizontal drive is “latched” off for
about 5 seconds, after which, restart is attempted.
SHUTDOWN CIRCUIT OPERATION
The flyback pulse voltage from Pin 6 of TX3201 (Flyback Trans-
former) is peak detected (rectified) by the action of diode
D3206 and capacitor C3214. This forms a DC voltage appear-
ing on C3214 representative of the CRT anode voltage (HV)
produced by T3201. This voltage is divided down by precision
resistors RX3214, RX3215, RX3216 & RX3217. This lower volt-
age, appear on the non-inverted input (pin 5) of IC3201.
If the CRT anode voltage become excessive, pin 5 of IC3201
will be higher than inverted input of pin 6. This will cause the
output of pin 7 to rise to approximately 15 volts. This signal
(SD_DRV) is sent to the base of Q4000 causing Horizontal
Drive to be disabled and latched, which causes the HV to
shutdown. In about 5 seconds, the shutdown circuit resets
(Pins 8, 9 & 14 of IC2900), the Horizontal Drive and HV will be
reestablished. The circuit formed by Q2907, C2913, C2916,
D2908, R2923, R2935, R2936, and R2937 disables the HV
compensation output (Q2902-b signal) during turn on and shut-
down conditions (transients).
CRT ANODE HIGH VOLTAGE MEASUREMENT PROCEDURE
Each CRT screen has it’s own safe operating Anode Voltage
and shutdown voltage. Critical Safety components (designated
with an ‘X’ in the component designator) are designed to
operate the CRT at a safe operating Anode voltage and pro-
vide proper shutdown thresholds. If replacement of any of
these components is deemed necessary, it is important to use
original type Zenith replacement components.
After a replacement is made, confirm proper Anode voltage
using the following procedure.
Measurement of the CRT Anode voltage must be performed
with no visible raster on the screen and operating at nominal
horizontal scanning frequency 15.734 or 37.9 Khz (TV or SVGA
signal).
After discharging the CRT, connect a high impedance high
voltage meter to the CRT anode. Turn the television ‘On’ and
confirm 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.
HV SHUTDOWN MEASUREMENT PROCEDURE
1. Adjust the beam current to 0 mA in NTSC mode.
2. Apply a variable DC voltage to pin 10 of the PTD1 connec-
tor, from 20 to 0 Vdc, starting at 20 Vdc.
3. Slowly decrease supply towards zero.
4. Remove DC voltage from pin 10 of PTD1.
5. After approximately 5 seconds, verify that the HV is rees-
tablished (High Voltage Reset).

OVERVIEW
SECTION 1
The CS series chassis will be used on the E-Line Commer-
cial Products. The Presentation Series PC-to-TV monitor
receivers were designed for educational and business
applications. This manual covers 27, 32, and 36 inch
screen sizes. The concept of this chassis is to make one
main board for all models and one power supply board
for all models in a particular screen size. Additional plug
in boards with jack packs may be added to the chassis
to accommodate the different features.
The CS series chassis features 11 IC’s and 3 peripheral
devices for all signal, sync and sweep processing. The
ICX2200 handles the Base Band signal processing, the
RGB processing, and video switching for 4 systems (HV
sync signal processing included).
ICX2201 integrates the luminance signal processing,
Chroma signal processing, and the sync signal. The
ICX2600 was developed for various types of direction
compensation for point scan/multi scan TVs. The IC1400
includes functions such as stereo modulation, SAP (Sepa-
rate Audio Program), dBx noise reduction, and sound
processing. The IC2900 is an A/V switch which deter-
mines which auxiliary video and audio signals will be
processed by the video processor, also it can switch the
IF video signal. IC6000 is the main microprocessor and
IC6001 is the main memory.
All CS models are module level repair only. The table be-
low contains basic information on the Presentation Se-
ries. For more datails please see the Interconnect Dia-
gram in this Manual (section 5).

CONNECTIONS
The connection center on the rear of the TV allows for
connection of the viewing source. The diagrams on the
next page list the use of each jack on the connection
center.
OUTPUTS
S-Video Loop out luminance is on pin 34 and chroma is
on pin 32 of ICX2900. The analog stereo comes from
pins 6 and 7 of IC1400 before running through a pre-
amplifier circuit. After the pre-amp stage, the audio passes
to the jackpack.
CAMPORT
Some models have video and right/left audio input jacks
on the front of the receiver. These jacks can be used to
view video tapes from a VCR or Camcorder. When the
video cable is plugged into the jack, the shorting jack
J1 opens, placing a high at pin 10 of the IC6000 micro-
processor. 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 switch-
ing into tuner mode until the video cable is discon-
nected.
SUPERPORT - MPI
Zenith Commercial Product receivers are now being
adapted to interact with other equipment. Prime ex-
amples of this can be found in Lodging and Health Care
situations where the set is controlled from the main of-
fice.
All this is made possible by the new technology that is
being built into these receivers. The SuperPort or Mul-
tiple Protocol Interface (MPI) jack and associated cir-
cuitry allow remote operation of the set.
MULTIPLE PROTOCOL INTERFACE
Television functions and features are controlled by the
communication of commands and status information
through the Superport by the MPI interface.
EBC (EDGE BOARD CARD)
Allows easy access for removing/installing accessory
modules providing a rail mounted slide-through card.

USING PCZTV
Once the connections to the receiver monitor have been
completed, the receiver/monitor can be used to view
images from the computer.
1. Turn on the receiver/monitor
2. Tune the receiver/monitor to the appropriate source.
3. Turn on the computer.
4. The computer images should be visible on the screen.
VIDEO ADJUSTMENT
Adjustments to the computer video image are controlled
through the remote control. The 2 and 8 buttons shift
the display vertically. The 4 and 6 buttons shift the dis-
play horizontally. 1 is Zoom, 0 is freeze, and 5 gives
menu access.
CONNECTIONS
RECORDING THE COMPUTER IMAGE
If your VCR has an video input jack, the computer im-
ages can be recorded to video tape. Connect the VCR as
described by the illustration on the previous page.
This jack pack provides L/R audio input paired with com-
puter data input which will allow recording of audio
along with the video images. Your computer must pro-
vide audio out that can be connected to the jack pack
input on the receiver/monitor.
CHOOSING A DESKTOP PATTERN
Because of a television’s low resolution (as compared to
that of a computer monitor), avoid using computer desk-
top patterns that consist of elaborate designs or colors.
These can tend to vibrate or distort on the screen.
The recommended desktop pattern is either Black, a lim-
ited gray design, or some other solid dark color.
VIDEO DISTRIBUTION AMPLIFIER
If your receiver/monitor will be part of a closed circuit
network using a cable that is longer then 25 feet, or if
several sets will be used together using the loop out
jack, then a video distribution amplifier will probably
be necessary to ensure adequate signal strength is pro-
vided. These types of amplifiers can be purchased sepa-
rately in many consumer audio/video stores.

REMOTE INFO
PROGRAMMING THE REMOTE
If you’re using Zenith products, the remote is already
programmed for most common codes: TV = 101, VCR =
201, CABLE = 353, and AUX = 401. For other brands, or
if your remote fails to control your Zenith products, you’ll
have to program the remote.
After installing the batteries, follow these steps for each
product:
1. Press and hold PRG using a blunt pointed object.
Release PRG after the indicator light turns on.
2. Press the device button to be programmed (CATV,
VCR, AUX, or TV).
3. Enter the 3-digit product code from chart on next
page.
4. Press and release ENTER to save the code.
5. Point the remote at product and press POWER to test
the product’s operation. If it does not turn on,
reprogram remote using a different code.
6. Write the codes on the label inside the battery
compartment for future reference.
AUTO FIND
If none of the codes in the code table operate your
equipment, use Auto Find to search for the proper code.
1. Turn on the product you want to operate.
2. Press and hold PRG using a blunt pointed object.
Release PRG after the indicator light turns on.
3. Press the key to be programmed (CATV, VCR, AUX, or
TV).
4. Enter “000”, then press ENTER within two seconds.
Auto Find is active after the indicator light flashes
and remains lit.
5. Point the remote at the product.
6. Press and release POWER repeatedly, about once a
second, until your product turns off. The indicator
light turns off when you press POWER and on when
you release it.
7. Press ENTER immediately to save the code. The
indicator light flashes to indicate the code has been
saved.
8. Press POWER to turn On your product.
9. Test your product. If the remote fails to operate some
of the basic functions, use Auto Find again to search
for a better code. (Auto Find resumes its search after
the last code that was entered and saved in step 7).
NOTE: If the indicator light stays on as you press
POWER, Auto Find has tried all of the codes. If
the product you want to control has not turned
off, your remote will not work with that product.
To cancel Auto Find, press PRG at any time during
Auto Find.
CABLE BOX
This remote can control the cable/converter box volume
and muting (instead of the TV’s) if available on your
equipment.
1. Program the cable/converter box normally.
2. After programming the cable/converter box, Press and
hold PRG again using a blunt pointed object. Release
PRG after the indicator light turns on.
3. Press and release the device button the cable box is
assigned to.
4. This time, enter the special code 3-9-9 instead of
the product code.
5. Press and release ENTER to save.
VOLUME OVERRIDE
These remotes can override TV, VCR, or Video Disk Player
volume functions with an amplifier’s volume and mut-
ing.
1. Program the amplifier normally.
2. After programming the amplifier, Press and hold PRG
again using a blunt pointed object. Release PRG after
the indicator light turns on.
3. Press and release the device button whose volume
control is to be replaced by the amplifier volume
control. For example, pressing TV will operate the
amplifier’s volume while the remote is in TV mode.
4. This time, enter the special code 4-9-9 instead of
the product code.
5. Press and release ENTER to save.
AUXILIARY CAPABILITY
This remote can control up to seven devices. If the re-
mote has been programmed for four components using
the TV, VCR, CABLE, and AUX keys, you may also program
it for up to three additional using AUX+1, AUX+2, and

TO PROGRAM AUX+1, AUX+2, AND AUX+3
1. Locate three-digit code for product in code table.
2. Press and hold PRG until indicator lights up.
3. Press the AUX and 1 simultaneously to select AUX+1.
4. Enter the three-digit code and press ENTER. The indi-
cator light should flash and then turn off to indicate

AUTO PROGRAM
The Auto Program feature automatically searches for all
available channels and marks them as ‘added’ so that
they may be accessed via the channel Up/Down key.
In the Auto Program screen:
• A message at the top displays “Auto Program” to
let the customer know that they have entered the
Auto Program feature.
• A line at the bottom of the screen shows that the
Up/Down and Left/Right Arrow keys are used for
Auto Program selections.
• The current RF input type (Off Air Antenna or Cable
TV) is highlighted. Use the Up/Down Arrow keys to
change the RF input type.
To start the Auto Program, press the Left/Right Arrow
key. If the Cable TV input type is selected, the Auto
Program routine will determine what type of cable system
is present.
Notes:
• Auto program clears all blanked channels, which were
added.
• While searching for channels, all keys except for the
Power key are disabled. This prevents an incomplete
Auto Program procedure.
• Running the Auto Program will clear the factory mode,
if it was active. This happens at the end of the Auto
Program.
• If the Auto Program line in the Setup Menu is ‘red’,
this indicates that the module did not pass one of
the test equipment’s tests.
If no channels are found then the following message
will appear: “Make sure that the cable/ant. is connected
and try again.”
CHANNEL ADD/DEL/BLNK
After running the Auto Program, all channels found by
the Auto Program feature will be marked as ‘Added’.
However, some of these channels may be scrambled, or
undesired by the customer. The Channel Add/Del/Blnk
feature allows the customer to selectively mark any
channel as ‘Deleted’ or ‘Added’.
To change the status of a channel, press the Right/Left
Arrow key.
To change the channel while adding or deleting channels,
use the Channel Up/Down keys, or press the desired
channel digits followed by ‘Enter’. If Channel Up/Down
is pressed the next or previous channel, which was marked
‘Added’, will appear. If only one channel is present, to
change the channel the customer must use the digit
keypad to select a channel.
CH. LABEL
This feature allows the customer to select a channel label
for the current station. This channel label is displayed
in the Channel/Time display. Initially, all channel labels
are set to ‘——‘ (which means that auto label is selected).
To change the current channel label, press the Left or
Right Arrow key.
To change the channel while adjusting channel labels,
use the Channel Up/Down Arrow keys, or press the desired
channel digits, followed by ‘Enter’. (If Channel Up/Down
is pressed, the next or previous channel that was marked
‘Added’ will appear.)

Notes:
• When the “- - - -” label is selected, then the Auto
channel label is activated, in other words, the program
automatically takes the channel label of the signal
that is sent by broadcasting through the XDS service.
• If the label None is selected, the Auto channel label
is not activated.
PROGRAMMABLE CHANNEL LABELS
Besides the labels already provided, the customer may
select a label of his or her choice. The programmable
labels are at the end of the list of labels already provided.
Pressing the volume key allows the editing of the first
character. In this case it is the “L” that would start
blinking. However, if the Left volume key is pressed, the
“1” is the character that would begin to blink. When the
character begins to blink, the customer may select
another character.
The method of selecting another character is by pressing
the channel Up/Down key. If the channel up key were
pressed, the character displayed would be an “M”. On
the other hand, if the channel down key is pressed, the
character displayed is an “L”.
There are 20 programmable labels that the customer may
program. The available characters to choose from are
the following:

Programmable Channel Labels
Notes:
• If the mute key is pressed, the label is cleared. The
channel is automatically given the label NONE.
• Any changes done to a label are stored even if another
keystroke occurs. For example if the customer is
programming a label and the first 3 letters are entered
and accidentally the ENTER key is pressed or the Menu
key is pressed, the label is stored with only the three
characters being changed. The other two remain
unchanged. The programmable labels have 5
characters that may be programmed.
• If, for example, the 10th label is programmed as ABCDE,
then the customer decides to clear it. The channel
automatically receives the label NONE and label 10 is
restored to LAB10.
• Using the Channel Up/Down the customer may select
the above-mentioned characters.
CLOCK SET
This Setup Menu Line allows the customer to set the
clock time and date.
When no time is set, the display shows: - -: - -
There are two ways to set the time:
1. Direct Entry is preferred. Use the digit keys, followed
by ‘Enter’ or Select Up/Down.
2. Left/Right Arrow keys.
When the first digit is introduced, the display shows:

When the time is set, the display shows:
hh:mm AM
where d = digit, mm = minutes, and hh = hours.
To select either AM or PM, the Timer key must be used.
Pressing the Timer key, toggles AM and PM to allow the
customer to select AM or PM.
Notes:
• Entering the time in 24 hour (Military) format is
allowed. AM/PM will be toggled automatically.
• Entering an invalid time (“0” for example) will result
in the clearing of the current time - - : - -.
• When only one digit is pressed and no other is pressed
in an interval of seven seconds, the current time will
be cleared.
