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.

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, check 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 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.

Good Earth Ground
such as the Water
Pipe, Conduit, etc.

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.

SHUTDOWN CIRCUIT THEORY OF OPERATION

The HV shutdown network feeds the shutdown or X-ray
protection input, pin 29, of ICX2200 video processor
IC. To perform the shutdown or activate the X-ray pro­tection requires getting +3.5 VDC or more (threshold is

3.5 VDC) on pin 29.

A pulse voltage is derived from the sweep transformer
(TX3201 pins 5 & 6) and applied to a half wave rectifier
circuit (DX3001 & CX3001). This DC voltage is supplied
to a precision resistor divider, which sets the HV shut­down point.

This voltage is applied to the Zener diode ZDX3002 12.0V.
The resulting voltage from the Zener diode and the gen­eral-purpose diode is supplied to a DC filter (CX3000
RX3002) and finally to pin 29 through RX3000M.

The Zener Diode’s function is to keep a constant voltage
on its terminals. Since the Zener is in series with the
ICX2200 (see the figure below) an excess of voltage will
appear on pin 29. So, if the voltage coming from the
sweep increases drastically (as the HV does), the thresh­old voltage on pin 29 of ICX2200 should be reached and
the TV set will turn off immediately.

NOTE: If a SHUTDOWN test is performed, the

microcontroller will turn the TV off. The set will
not turn on until it is unplugged and then
plugged back in (resets the microcontroller).

The table below contains specifications for the Shut­down Circuit:

INTRODUCTION

The XC chassis is a single sided printed circuit board (PCB) very similar to the CA Chassis. During the manufacturing
process, the microprocessor will be programmed for any added features. Additional plug in boards with Jack Packs will
be added to the chassis to accommodate the different features: Stereo, Mono, Video/Audio in, etc.

The ICX2200 integrated circuit (IC) handles all of the audio/video, sync, and drive processing. The IC6000 is the main
microprocessor and the IC6001 is the EEROM memory. The keyboard and IR detector are tied directly to the IC6000. The
IC2100 handles the vertical sweep. At power on, voltages for the vertical and video output circuit are derived from this
sweep circuit.

Feature and component information is listed below for each of the XC models.

REMOTE PROGRAMMING

PROGRAMMING INSTRUCTIONS

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.

Make sure the batteries are installed and 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 and release the device key for the product
being programmed (CATV, VCR, AUX, or TV).

3. Enter the 3-digit product code from the chart on
the next page.

4. Press and release ENTER to save the code.

5. Point the remote at the product and press POWER
to test the product’s operation. If it does not turn
on, reprogram the remote using a different code.

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. Once the product turns off, 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
the functions you use most often, 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, this
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 same button used in set 1.

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
muting.

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
remote 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 AUX+3.

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 a three-digit code, then press ENTER. The
indicator light should flash, then turn off to
indicate code is accepted. If the light stays on,
repeat steps 3 and 4 or try a different code.
