IMPORTANT SAFETY NOTICEThis manual was prepared for use only by properly trained audio-video servicetechnicians.

When servicing this product, under no circumstances should the originaldesign be modified or altered without permission from Zenith ElectronicsCorporation. All components should be replaced only with types identical tothose in the original circuit and their physical location, wiring and lead dressmust 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 componentdesignators and are required to maintain safe performance. No deviations areallowed 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 intothe set is not delayed until the new service literature is printed.

CAUTION: Do not attempt to modify this product in any way. Never performcustomized installations without manufacturer’s approval. Unauthorizedmodifications will not only void the warranty, but may lead to property damageor user injury.

Service work should be performed only after you are thoroughly familiar withthese safety checks and servicing guidelines.

GRAPHIC SYMBOLS

The exclamation point within an equilateral triangle is intendedto alert the service personnel to important safety information inthe service literature.

The lightning flash with arrowhead symbol within an equilateraltriangle is intended to alert the service personnel to the presenceof noninsulated “dangerous voltage” that may be of sufficientmagnitude to constitute a risk of electric shock.

The pictorial representation of a fuse and its rating within anequilateral triangle is intended to convey to the service personnelthe following fuse replacement caution notice:CAUTION: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE,REPLACE ALL FUSES WITH THE SAME TYPE AND RATING AS MARKEDNEAR EACH FUSE.

SERVICE INFORMATIONWhile servicing, use an isolation transformer for protection from AC line shock.After the original service problem has been corrected, make a check of thefollowing:

FIRE AND SHOCK HAZARD1. 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 beenreinstalled per the original design. Be sure that the safety purpose of thepolarized 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 looseforeign particles.

4. Check for physical evidence of damage or deterioration to parts andcomponents, for frayed leads or damaged insulation (including the ACcord), and replace if necessary.

5. No lead or component should touch a high current device or a resistorrated at 1 watt or more. Lead tension around protruding metal surfacesmust be avoided.

6. After reassembly of the set, always perform an AC leakage test on allexposed metallic parts of the cabinet (the channel selector knobs, antennaterminals, handle and screws) to be sure that set is safe to operatewithout danger of electrical shock. DO NOT USE A LINE ISOLATION TRANS-FORMER DURING THIS TEST. Use an AC voltmeter having 5000 ohms per voltor more sensitivity in the following manner: Connect a 1500 ohm, 10 wattresistor, paralleled by a .15 mfd 150V AC type capacitor be-tween a known good earth ground water pipe, conduit, etc.) and theexposed metallic parts, one at a time. Measure the AC voltage across thecombination of 1500 ohm resistor and .15 mfd capacitor. Reverse the ACplug by using a non-polarized adaptor and repeat AC voltage measure-ments for each exposed metallic part. Voltage measured must not exceed0.75 volts RMS. This corresponds to 0.5 milliamp AC. Any value exceedingthis limit constitutes a potential shock hazard and must be correctedimmediately.

X-RADIATION1. Be sure procedures and instructions to all service personnel cover the

subject of x-radiation. The only potential source of x-rays in current TVreceivers is the picture tube. However, this tube does not emit x-rays whenthe HV is at the factory-specified level. The proper value is given in theapplicable schematic. Operation at higher voltages may cause a failure ofthe picture tube or high-voltage supply and, under certain circumstancesmay 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 andreliable high-voltage meter.

4. When the high-voltage circuitry is operating properly, there is no possibilityof an x-radiation problem. Every time a chassis is serviced, the brightnessshould be run up and down while monitoring the high voltage with ameter, to be certain that the high voltage does not exceed the specifiedvalue and that it is regulating correctly.

5. When troubleshooting and making test measurements in a product with aproblem of excessively high voltage, avoid being unnecessarily close tothe picture tube and the high voltage power supply. Do not operate theproduct longer than necessary to locate the cause of excessive voltage.

6. Refer to HV, B+, and shutdown adjustment procedures described in theappropriate schematics and diagrams (where used).

IMPLOSION1. 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 INSTALLATION1. 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 heatedair flow.

2. Avoid conditions of high humidity such as: outdoor patio installationswhere dew is a factor, near steam radiators where steam leakage is a factor,etc.

3. Avoid placement where draperies may obstruct venting. The customershould also avoid the use of decorative scarves or other coverings thatmight obstruct ventilation.

4. Wall- and shelf-mounted installations using a commercial mounting kitmust follow the factory-approved mounting instructions. A product mountedto a shelf or platform must retain its original feet (or the equivalentthickness in spacers) to provide adequate air flow across the bottom. Boltsor screws used for fasteners must not touch any parts or wiring. Performleakage tests on customized installations.

5. Caution customers against mounting a product on a sloping shelf or in atilted 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 smallcasters across thresholds or deep pile carpets.

7. Caution customers against using a cart or stand that has not been listedby Underwriters Laboratories, Inc. for use with its specific model oftelevision receiver or generically approved for use with TVs of the same orlarger screen size.

8. Caution customers against using extension cords. Explain that a forest ofextensions, sprouting from a single outlet, can lead to disastrousconsequences to home and family.

PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS

X-RADIATIONTo prevent possible exposure to x-radiation caused by excessive CRTAnode voltage, the AB Chassis incorporate a “High Voltage Shutdown”circuit. This circuit senses the level of flyback pulse from the “FlybackTransformer” representative of the actual high voltage on the CRT anode.When this level exceeds a predetermined voltage, the circuit shuts downthe horizontal drive, preventing further generation of anode voltage. Inthis condition, the horizontal drive is “latched” off for about 5 seconds,after which, restart is attempted.

SHUTDOWN CIRCUIT OPERATIONThe flyback pulse voltage from Pin 6 of TX3201 (Flyback Transformer) ispeak detected (rectified) by the action of diode D3000 and capacitorC3001. This form a DC voltage appearing on C3001 representative of theCRT anode voltage (HV) produced by T3201. This voltage is divided downby precision resistors RX3001, RX3002, & RX3003. This lower voltage,appear on the positive input (pin 5) of IC3101.

If the even CRT anode voltage become excessive, in IC3101 the positiveinput (pin 5) will be higher than negative input of pin 6 and thereforehis output (pin 7) will go to high level, at approximately 15 volts. Thissignal (SHUTDOWN) is send to Base of Q3201 causing Horizontal Drive tobe disabled and latched causing HV goes down. In about 5 seconds, theshutdown reset circuit (Pins 8, 9 & 14 of IC3100) enable again theHorizontal Drive and HV must be reestablished. If the shutdown condi-tion persist the circuit goes into hiccup mode.

The circuit formed by Q3104, C3113, C3108, D3107, R3131, R3132, R3133and R3134 disable the HV compensation output (Q3102-B signal) duringturn on and shutdown conditions (transients).

CRT ANODE HIGH VOLTAGE MEASUREMENT PROCEDUREEach CRT screen size has it’s own safe operating anode and shutdownvoltage. Critical safety component (designated with an ‘X’ in the compo-nent designator) are designed to operate the CRT at a safe operatinganode voltage and provide proper shutdown thresholds. If replacementof any of these components are deemed necessary, it is important to useoriginal type Zenith components. After replacement is made, confirmproper anode voltage using the following procedure.

Measurement of the CRT anode voltage must be performed using a highimpedance-high voltage meter, with no raster on the screen, and operat-ing at nominal horizontal frequency, 33.75 Khz (HDTV signal).

After discharging the CRT, connect a high impedance-high voltage meterto the CRT anode. Turn the television ‘on’ and confirm a good signal isbeing displayed. Reduce Brightness and Contrast settings until thepicture is well extinguished.

Observe the anode voltage meter reading and compare with the tablebelow for the proper CRT screen size. If the voltage reading is higherthan the maximum, verify circuit component values and proper opera-tion.

HV SHUTDOWN PROCEDUREAdjust beam current to 0 mA. Connect a variable Resistor (10 MW)between pin 2 and pin 3 of 2W6 connector, and decrease slowly theresistance value from 10 MW to 0 W. Measure shutdown HV. Increase theresistance value to 10 MW. After 5 seconds, approximately, verify thatthe HV must be reestablished (High Voltage Reset).

CIRCUIT OVERVIEWLARGE SIGNAL MODULEThe AB Large signal module is a COLD chassis consistingof a single sided circuit board. It has two SMPSs (OneStand-by and other switched)sections, one Horizontal &Vertical Deflection section, and one daughter board. Thepower supply section features nineteen IC's for voltagesources.

A new feature has been added that switches from themaster power supply to a slave power supply.

This chassis uses two switching regulator to develop upto 150 Watts each using the quasi-resonant topology.The AC line voltage is supplied via fuse FX3400 and anEMI filter consisting of CX3401, LX3400, CX3402, LX3401,and CX3405 and delivered to two bridge rectifiers BR3400and BRX3450 (which is 212-00172-04). The AC operationrange is between 90 Vrms to 132 Vrms. The output voltagefrom the rectifiers (+VM and +VSLV) is supplied to theMain Power Regulator and Switched Power Regulator.

MAIN POWER SUPPLYThe MASTER SMPS consists mainly of ICX3612 and threecircuits that regulate its behavior. TX3612 is the choppertransformer that performs the power conversion. Thethree circuits mentioned modify the response of themain regulator according to the power supply condition.

There two possibilities: Quasi-Resonant Mode and 20kHz. The Quasi-Resonant mode handles the power whenthe application is turned on. When off, the 20 kHz modeallows minimum power consumption. The third circuitcorresponds to the power down detector. The MASTERSMPS handles 4 output voltages (see next page forreference).

SWITCHED POWER SUPPLYThe second SMPS is switched on/off through relayKX3870, which receives the POWER-CTRL 2 signal fromthe microcontroller IC6000. The +VSLV is a non-regulated voltage from the second bridge rectifier(mentioned above)r, but switched from the KX3850.When the KX3850 is switched on, the switched powersupply provides seven main switched voltages (see nextpage for reference).

Other voltages are generated from the Main SMPS outputvoltages and driven by two Step Down Regulators inorder to provide reliable output voltages intended forthe digital card.

SERVICINGDEGAUSSINGThe ADTV chassis employs an innovative method ofdegaussing, just like former Zenith TVs it is performedthrough software in order to obtain a properdemagnetization for these screens.

IC6000 generates a pulse about 1 second on pin 48 setto high (about 4.8 VDC) through RX3900 (4.7K 5% ¼watt).

It is applied to QX3900, which drives the 12 VCD relayKX3900 in series with a current limiting resistor. So thedegaussing is performed when the degauss coil is pluggedto the 4T8 connector ends.

HORIZONTAL & VERTICAL DEFLECTIONThe AB chassis was designed to support only onehorizontal frequency for DTV, 33.75Khz. It supplyshorizontal and vertical currents to the deflection yokecoil and the high voltage generation for the CRT. Thissection is dependent on other circuits in the mainchassis to provide drive signal, DC control voltage,s anddeflection corrections. This section can be divided into6 functional blocks:

• Horizontal Deflection and HV Generation

• Base Drive

• HV Compensation

• Shutdown Circuit

• Vertical Deflection

HORIZONTAL DEFLECTION AND HV GENERATIONThe Horizontal Deflection circuitry is a common flybacktopology used in many television and monitorapplications. QX3200 is the Horizontal Output Transistor.When QX3200 is initially turned on, current is allowedto flow from the B++ supply through TX3100, TX3201,and QX3200. This allows energy to be stored in TX3201.When QX3200 is turned off some of this energy is returnedto charge the S-capacitor(s) CX3208, CX3210, and C3232.After several cycles (repeating at scanning frequency)sufficient voltage appears across the S-capacitorsproviding an additional path producing current flowthough the horizontal deflection yoke coil (connector4X4). The negative current path is provided by thedamper diode DX3200. The result is a positive andnegative sawtooth current through the horizontaldeflection coils (approximately 11 to 17 Amps peak topeak). When QX3200 is turned off, about 1100 Voltspeak of flyback voltage is produced resulting from thestored energy in the horizontal deflection coils andTX3201. This voltage is induced to secondary windingsof TX3201 to generate the high voltage from 28 to 30KV. The flyback (or retrace) period is about 5.0 s.

Horizontal Deflection and HV Generation Block Diagram

Page 26: Zenith c32v23 Service Manual

PV154 - 923-03497 3-4 AB - SERVICING

SERVICING

A sensing resistor inside of TX3201 provides a DC voltageproportional to the CRT anode voltage and is used like aprimary feedback for the HV compensation circuit. Asecondary winding on TX3201 (pin 6) provides a lowvoltage flyback pulse (H-FLYBK) used for synchronizationof the Scan Boost Converter and the HV Compensationcircuit. A capacitive divider, CX3205 and CX3206, providea low voltage flyback pulse (H-FBP) used forsynchronization, phase comparison, etc.

The linearity coil L3200 is saturating inductor skewedby a permanent magnet bonded to the coil. It producesa non-linear inductance curve vs current. Thischaracteristic cancels non-linearity in the deflectioncurrent caused by horizontal deflection coil resistance.

BASE DRIVE(Refer to figure on the next page). The Base Drive(Proportional Drive) circuit provides high forward andreverse current to drive the base of the horizontal outputtransistor QX3200 from a low level input (H-DRV fromthe deflection processor ICX2600 in main chassis). Thissignal is approximately 9 Volts peak to peak at theoperating frequency and has a duty cycle of about 40%high, 60% low.

Current from H-DRV is amplified by transistors Q3203and Q3204 providing low impedance to rapidly drivethe gate of the driver transistor Q3205. This action resultsin an alternating current flow in the primary of drivertransformer T3200. During Q3205 on time energy is storedin T3200 and rapid turn off of QX3200 is initiated. DuringQ3205 off time the energy previously stored in T3200 isused to drive the base of QX3200. A winding in T3200from the emitter of QX3200 to ground provides pulseshaping to optimize the base drive and improve efficiency.

HV COMPENSATIONA resistor inside of the sweep transformer senses the CRTanode voltage (Pin 14). The DC voltage appearing onthis resistor is used in one of the operational amplifiersof IC3101 to provide the error voltage needed to regulatethe HV to a specified level.

The error voltage is compared with a ramp signalgenerated in one comparator of IC3100 and sinchronizedby the flyback pulse (H-FLYBK) at horizontal scanningfrequency to modulate the pulse width in the output todrive the gate of the switching transistor Q3103. Thisramp signal is present only during the flyback pulse.

Q3103 is on during the scan time and as long as theerror voltage is higher than the ramp signal. This allowsenergy to be stored in TX3100. When Q3103 is turnedoff, the resonant circuit formed by C3109 and the primaryinductance of TX3100 produce a flyback voltage of about400 volts peak resulting from the stored energy inTX3100.

This voltage is induced to the secondary windings ofTX3100 to add to the voltage generated in the horizontaldeflection circuit. This induced voltage is used tocompensate load variation (beam current variation) inthe HV flyback transformer TX3201. RX3335(potentiometer) is used to adjust the high voltage to aspecified level. (Refer to the figure on the next page).

SHUTDOWN CIRCUIT OPERATION(Refer to figure on the next page). The flyback pulsevoltage from pin 6 of TX3201 (flyback transformer) ispeak detected (rectified) by the action of diode D3000and capacitor C3001. This forms a DC voltage appearingon C3001 representative of the CRT anode voltage (HV)produced by TX3201. This voltage is divided down byprecision resistors RX3001, RX3002, and RX3003. Thislower voltage appears on the positive input (pin 5) ofIC3101. In the event the CRT anode voltage becomesexcessive, in IC3101 the positive input (pin 5) will behigher than negative input (pin 6) and therefore thisoutput (pin 7) will go to high level at approximately 15volts. This signal (SD-DRV) is sent to the base of Q3201causing the horizontal drive to be disabled and latchedcausing HV to goe down. In about 5 seconds theshutdown reset circuit (Pins 8, 9 & 14 of IC3100) enablesthe horizontal drive and HV must be reestablished. Ifthe shutdown condition persists, the circuit goes intohiccup mode. The circuit formed by Q3104, C3113,C3108, D3107, R3131, R3132, R3133, and R3134 disablethe HV compensation output (Q3102-B signal) duringturn on and shutdown conditions (transients).

VERTICAL DEFLECTION(Refer to figure on the next page). The vertical deflectioncircuit (ICX2100) is a linear amplifier that can directlydrive the yoke current (including the required DCcomponent). The sawtooh waveforms needed as inputsby ICX2100 are generated in the Deflection ProcessorICX2600. V-PROT is an image of vertical deflection currentand it is used by the Deflection Processor to protect theCRT.

AUDIO SYSTEMThe AB chassis is offers up to five audio input sourcesand an AUX output for MONITOR through the RF Switch.The tuner delivers IF signals that are processed by U1200and U1201 saw filters. Finally the IF signal is applied toIC1203 which contains IF amplifiers and AGC circuits.AGC adjustment is manually done through R1242. ThisIC also delivers the down converter digital IF signal tothe digital board which is connected to CNP200A andCNP201A connectors. The it processes the audio andvideo signals and the audio is delivered to IC1400.

The IC1400 MSP44506 (0IMCRMN012A) is the audioprocessor. It handles the ANALOG IF and decodes theanalog stereo signal and includes audio tone controls.The EZBASS circuit is for BASS and TREBLE enhancement.The following is the block diagram for this IC and theaudio system.

RGB VIDEO OUTPUT AMPLIFIERThe video output module drives the RGB cathodes withvideo signal from the video drive ICX220M and has oneIC for each color. This circuit includes the filament orheater G1 and G2 connections and grounds. Specialcircuitry senses the cathode current which controls thecut off gains.

Audio AUX Output stage The AUX or MONITOR OUTPUT audiooutput is taken from IC1400, this signal has no processingand its output is constant.

Below is a simplified block diagram of the AB chassisvideo output circuit. The signal is first uncoupled atthe output of the video processor. Then the signal isderived by the video drive and is applied to the threetransistors Q2205, Q2206, & Q2207 (one per color). Afterthat RGB signals are injected to the video output board,it is amplified to the levels required for an acceptableimage on the screen. Each amplifier has a dedicatedsection for sensing the cathode current for the AKBsystem.

The resistor located at R5125 belongs to the Red colorsection. It has the same function of the R5145 of GreenColor section. The three ICs mentioned use the TDA6120Qfrom Philips. Each IC came be seen as a operationalamplifier but are configured as inverting amplifiers. Theinverting input is on pin 2 and the non-inverting inputis on pin 4. The Feedback resistor is R5125. It has again peaking network between pin 1 and pin 3. Thisnetwork is internally connected to the collectors of thedifferential input transistors.

Page 31: Zenith c32v23 Service Manual

PV154 - 923-03497 3-9 AB - SERVICING

SERVICINGThe input signal is connected to the inverting input ofthe amplifier through resistor R5121 to avoid Hifrequency oscillations. The non-inverting input isconnected to a voltage bias formed by resistors R5101and R5102. C5122 is for AC decoupling and C5123 isfor hi frequency filter purposes (one for each IC). The ICtakes this voltage bias as a reference voltage for theinput signal. So, by means of moving this referencevoltage the black level could be established. Thisreference voltage is the same for the three-coloramplifiers.The cathode output is from pin 12 of the IC. This signalis passed through transistor Q5121 with the purpose ofsampling the cathode current. This cathode outputtravels through resistors R5127, R5128, and the coilL5121 for peaking improvement.TDA6120Q (221-01404) consists of one monolithicvideo output amplifier for each color. This amplifier canbe split-up in two amplifier stages in series. This givesrise to the term trans-admittance trans-impedanceamplifier. At the second stage voltage, the currentfeedback travels through resistor R5125 connected fromOUT (pin 13) to IN (pin 5). The trans-admittance of thefirst stage is chosen by means of a resistor between pin1 and pin 3, represented on this circuit by R5122.The advantage of this amplifier configuration is that ahigher bandwidth (around 30Mhz) can be realized withrelation to the well know operational amplifier withvoltage feedback. Furthermore, the amplifier has adifferential input which makes the amplifier less sensitiveto interference and flexible regarding DC-DC transfer.Also, this configuration has high input impedance withthe advantage of not loading the drive stage. The signalinput travels through a differential pair of transistors.The signal is connected on pin 2 of the inverting voltageinput. The input configuration consists of a bipolarNPN transistor in a long tailed pair configuration. Theinput current is 30uA.This IC is provided with a black current data pin. Onthis application pin 7 is not used. Instead of this pinthe current is sensed externally by means of transistorQ5121. The frequency response is improved by means ofa capacitor in series with a resistor connected betweenpins 1 and 3 of the IC. These are C5121 and R5123. Thevalue of these elements is a compromise betweenbandwidth, overshoot, and ringing.

Block diagram for the video output circuit:

SCAN VELOCITY MODULATORThe Scan Velocity Modulator is on a pair of coils installedunder the purity magnets. These coils perform as amagnetic dipole delaying or accelerating the screen spotin the areas of brightness variation.

It is installed on the neck of the CRT near the Yokeassembly. This module has access to three signals: video,half tone, and fast blanking. This circuit has severalsections to process the signals and to obtain a currentsignal which will be applied over the coil.

It has two inverter amplifiers, two push pull amplifiers,two follower emitter, one differential amp, one switch,and one commuter. There is a coil on the circuit whichreceives the current to produce an effect over the picture.

The video passes through an inverter amplifier to increasethe level signal and then it is coupled by a followeremitter to be differentiated. Another inverter amplifierincreases the signal generated by the differentiator andthen two steps of push pull amplifiers drive the signalto feed the Coil.

All the time the video is working there is a SVM operationthat improves and enhances the picture in each colortransition. The magnetic field produced by the loadedcoil affects the electron beams to achieve betterdefinition between colors on the screen. The SVMperformance can be adjusted through the factory menuwith item #105, named VMLEVEL, which has three levelsof intensity.
