The pictorial representation of a fuse and its rating within anequilateral triangle is intended to convey to the servicepersonnel the 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 transportedto 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 reinstalledper the original design. Be sure that the safety purpose of the polarized lineplug has not been defeated.
3. Soldering must be inspected to discover possible cold solder joints, soldersplashes, or sharp solder points. Be certain to remove all loose foreignparticles.
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 receiving tube or a resistor rated at1 watt or more. Lead tension around protruding metal surfaces must beavoided.
6. After re-assembly of the set, always perform an AC leakage test on all exposedmetallic parts of the cabinet (the channel selector knobs, antenna terminals,handle and screws) to be sure that set is safe to operate without danger ofelectrical shock. DO NOT USE A LINE ISOLATION TRANSFORMER DURING THISTEST. Use an AC voltmeter having 5000 ohms per volt or more sensitivity inthe following manner: Connect a 1500 ohm, 10 watt resistor, paralleled by.15 mfd 150V AC type capacitor between a known good earth ground (waterpipe, conduit, etc.) and the exposed metallic parts, one at a time. Measurethe AC voltage across the combination of 1500 ohm resistor and .15mfdcapacitor. Reverse the AC plug by using a non-polarized adaptor and repeatAC voltage measurements for each exposed metallic part. Voltage measuredmust not exceed 0.75 volts RMS. This corresponds to 0.5 milliamp AC. Anyvalue exceeding this limit constitutes a potential shock hazard and must becorrected immediately.
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 of thepicture tube or high-voltage supply and, under certain circumstances mayproduce 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 color chassis is serviced, thebrightness should be run up and down while monitoring the high voltagewith a meter, to be certain that the high voltage does not exceed thespecified value 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 to thepicture tube and the high voltage power supply. Do not operate the productlonger 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 heated air 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 customer shouldalso avoid the use of decorative scarves or other coverings that mightobstruct ventilation.
4. Wall- and shelf-mounted installations using a commercial mounting kit mustfollow the factory-approved mounting instructions. A product mounted toa shelf or platform must retain its original feet (or the equivalent thicknessin spacers) to provide adequate air flow across the bottom. Bolts or screwsused for fasteners must not touch any parts or wiring. Perform leakage testson 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 listed byUnderwriters Laboratories, Inc. for use with its specific model of televisionreceiver or generically approved for use with TVs of the same or larger screensize.
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.

X-RadiationTo prevent possible exposure to x-radiation caused by excessive CRTanode voltage, the CH-Flat chassis incorporate a “High VoltageShutdown” circuit. This circuit senses the level of a flyback pulsefrom the “Flyback Transformer” representative of the actual highvoltage on the CRT anode. When this level exceeds a predeterminedvoltage, the circuit shuts down the TV set, preventing further gen-eration of anode voltage.
Shutdown Circuit Operation(Refer to Figure below)The flyback pulse voltage from pin 6 of TX3201 (Flyback Trans-former) is peak detected (rectified) by the action of diode DX3001and capacitor C3003. This form a DC voltage appearing on C3003representative 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 diodeZD3000; 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 shut-down voltage. Critical safety component (designated with an ‘X’ inthe component designator) are designed to operate the CRT at asafe operating anode voltage and provide proper shutdown thresh-olds. If replacement of any of these components are deemed neces-sary, it is important to use original type Zenith components. Afterreplacement is made, confirm proper anode voltage using the fol-lowing procedure.
Measurement of the CRT anode voltage must be performed using ahigh impedance-high voltage meter, with no raster on the screen,and operating at nominal horizontal frequency, 15.75 Khz (NTSCsignal).
After discharging the CRT, connect a high impedance-high voltagemeter to the CRT anode. Turn the television ‘on’ and confirm a goodsignal is being displayed. Reduce Brightness and Contrast settingsuntil the picture is well extinguished.
Observe the anode voltage meter reading and compare with thetable below for the proper CRT screen size. If the voltage readingis higher than the maximum, verify circuit component values andproper operation.

CHANNEL BANKAllows choosing between one of 4 channel banks.Press SOURCE to change between banks.
BANK 1
PLANNING THE CHANNEL BANKSGenerally, TV channels are grouped into “program pack-ages” with terms that are proposed to the end user. Theuser then opts for a package. Below is an example ofhow TV channels may be grouped.
Channel Bank Program package
1 Basic cable channels
2 Extended cable channels
3 Extended with premium channels
4 Other cable service options
Sometimes only one or two channel banks may be needed.You may leave any unused bank with the channels. How-ever, you may want to leave at least one channel in anyunused 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 havenot yet run Auto Program.
ADDING/DELETING CHANNELSA previously prepared programming chart is helpful.1. Run AUTO PROGRAM (in the SETUP MENU). The
channels available at your cable/antenna will be
entered in all channel banks (1, 2, 3 and 4).Notes:• Channels previously blanked will be cleared;
channels entered that are not currently availablewill be deleted.
• The Blank Channel feature is global. A channelwill be blanked in all channel banks.
2. Select a channel bank with a remote press SOURCE/BANK (and repeat). The Channel BANK and BANKnumber will be displayed.
3. Use the ADD/DEL/BLNK option (also in the SETUPMENU) to customize your program package. Youmay delete channels or add some that have notbeen entered. You can also Blank a channel toaccommodate an audio-only program source or forin-house communication. The ADD/DEL/BLNKoption has more details.
4. AUX, FM Radio, VCR3, and VCR4 can be addedprovided they have been enabled in the FactoryMenu and the hardware that uses this feature ispresent on the chassis.
5. Repeat steps 2 and 3 to program another channelbank. It is best to do ADD/DEL customizing beforedoing BLANKING. ADD and DEL (not BLNK) can beused independently for channel banks 1, 2, 3, and4).
Note: Adding the channels VCR3 or VCR4 allows theTV to automatically tune to broadcast band channel 3or 4 regardless of what band type is selected. This

GENERAL INFORMATIONServicing the CH -Flat chassis.If the set is dead, first check the standby and switchedvoltages. If the switched voltages do not appear, checkthe power “On” circuit. If the power supply is OK andthe set will turn On, the Horizontal sweep circuit shouldbe checked next. Is horizontal drive available from thevideo processor chip? If the sweep system does notstart up, sweep-derived voltages will not be generated.
If the sweep and high-voltage circuits are OK and videoor audio are missing, then the audio/video/tunercircuits should be checked. If the receiver is workingbut some feature is not working, check the Service Menu.Bring up the Service menu and check to be sure that allitems are set correctly.
MODULE-LEVEL SERVICINGThe CH-Flat chassis is Module Level repair only.Replacement modules are available on an exchange basis.
If the CRT or Video processor IC is replaced, Black/Whitetracking must be reset. Refer to the Service Menus sectionof this book for Black/White tracking adjustments.
When troubleshooting video circuits, remember that allvideo travels through the Video/Audio switcher IC. Adefect in either of these IC’s can result in no video.
SERVICING THE POWER SUPPLYCheck the standby voltages first:VDC at CX3412 (usually 169.7 VDC when 120 VCA)+11 VSB at CX3611B+ at CX3850+13V at CX3662

HIGH VOLTAGE AND X RADIATION PROTECTIONTo prevent possible exposure to x-radiation caused byexcessive CRT anode voltage, the CH-FLat chassisincorporate a “High Voltage Shutdown” circuit. Thiscircuit senses the level of a flyback pulse from the“Flyback Transformer” representative of the actual highvoltage on the CRT anode. When this level exceeds apredetermined voltage, the circuit shuts down the TVset, preventing further generation of anode voltage.
SERVICING (continued)
Shutdown Circuit Operation (Refer to figure below)The flyback pulse voltage from pin 6 of TX3204 (FlybackTransformer) is peak detected (rectified) by the actionof diode DX3001 and capacitor C3002. This form a DCvoltage representative of the CRT anode voltage (HV)produced by TX3201. Precision resistors RX3006 andRX3004, divide this voltage down. This lower voltageappears on the zener diode ZD3000; when this voltageexceeds by 3.5 Vdc the “zener voltage” the HV shutdownoccurs (pin 29 of ICX2200).

NOTE: Each CRT screen size has it’s own safe operatinganode and shutdown voltage. Critical safety component(designated with an ‘X’ in the component designator) aredesigned to operate the CRT at a safe operating anodevoltage and provide proper shutdown thresholds. Ifreplacement of any of these components is deemednecessary, it is important to use original type Zenithcomponents. After replacement is made, confirm properanode voltage using the following procedure.
Measurement of the CRT anode voltage must beperformed using a high impedance-high voltage meter,with no raster on the screen, and operating at nominalhorizontal frequency, 15.75 Khz (NTSC signal).
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. ReduceBrightness and Contrast settings until the picture iswell extinguished.
Observe the anode voltage meter reading and comparewith the table below for the proper CRT screen size. Ifthe voltage reading is higher than the maximum, verifycircuit component values and proper operation.

PRELIMINARY SETUP1. 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. Followthe Convergence Procedure.
4. Adjust for best focus.
PURITY ADJUSTMENT1. Purity tab positioning. Set the 2 pole purity tabs
together in the 3 or 9 o’clock positions and the 4-and 6-pole purity tabs together in the 12 or 6 o’clockpositions.
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 isobtained.
6. Check for proper yoke tilt setting.
CONVERGENCE ADJUSTMENT1. 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 twotabs separately to converge the red and blue lineshorizontally. Move the two tabs together aroundthe neck of the CRT (in a 45° arc) from the top-dead-center position to converge the red and bluelines vertically.b. After the 4-pole control has been adjusted tosuperimpose the red and blue lines on top of oneanother. Use the 6-pole static adjustment to placethe converged red and blue lines over the greenline. Move the two tabs together around the neckof the CRT (in a 30° arc) from the top-dead-centerposition to move the lines vertically. Adjusting thetwo tabs separately will move the converged beamto the left or right.

VERTICAL-TILT WEDGE ADJUSTMENTThe vertical lines at 6 and 12 o’clock are converged byvertically tilting the yoke and inserting a wedge at thetop of the yoke until it is firmly seated between the CRTglass and the horizontal coils.
HORIZONTAL-TILT WEDGE ADJUSTMENTThe vertical lines at 3 o’clock and 9 o’clock are convergedby horizontally tilting the yoke and inserting a wedge.
Adjust first at 4 or 8 o’clock, whichever has the largerspace, until the wedge is firmly seated between the CRTglass and yoke coils. Then, insert the 3rd wedge in theremaining horizontal tilt position until it is firmly seatedbetween the CRT glass and yoke coils. Convergence atthe 3 and 9 o’clock should be maintained during thisoperation.
When the 3 wedges are firmly installed and positionedfor acceptable convergence, lock the wedges in placeby applying a 2.5 inches long strip of tape across thetabs of each wedge firmly against the CRT glass. TheCRT glass surface should be clean and free of dust andother foreign material.
UNUSUAL TILT CASEThere may be some instances where the picture tubeand yoke will require vertical tilt in the opposite (up)direction to obtain convergence. In such cases, insertthe vertical tilt wedge at the bottom (6 o’clock)position. Follow through on the horizontal tiltadjustment by using the 2 and 10 o’clock positions andsecure each wedge with a piece of tape, as describedabove.

IMPROVING CRT CORNER PURITYCRTs that display corner purity problems even afterfollowing the service procedures can be modified witha picture correction kit . The purity can be improved byplacing a picture-correction magnet (included in thekit) on the CRT funnel. Refer to the followingmodification steps and illustration to place the magnetproperly. Fully degauss the CRT before installingcorrection magnets.
MODIFICATION1. 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 magnetshield.
Note: If the magnet is placed over the internalmagnet shield, any apparent purity correctionwill disappear after degaussing. Reposition thecorrection magnet off the internal shield anddegauss again.
