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. 0.16uF Good Earth Ground such as the Water 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. Graphic symbols 1600 OHM IMPLOSION 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. 3828VD0205B i 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).

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.

AUX, FM Radio, VCR3, and VCR4 can be added provided they have been enabled in the Factory Menu and the hardware that uses this feature is present on the chassis. BANK 1 PLANNING THE CHANNEL BANKS Generally, TV channels are grouped into “program packages” with terms that are proposed to the end user. The user then opts for a package. Below is an example of how 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 5. 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.

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.

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. Flyback Pulse RX3007 RX3209 DX3001 RM3001 D3002 ZD3000 IN OUT RX3006 From Pin 6 TO PIN 29 ICX2200 Of TX3201 RX3005 C3003 C3002 3828VD0205B SHUTDOWN R3003 RM3002 C3001 RX3004 3-2 CH-FLAT - SERVICING SERVICING (continued) 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. CRT screen size 20" CRT Anode Voltage Nominal anode voltage (KV) 26 ± Tune in strong off air signal. Place a high impedance meter on pin #54 of ICX2200 or from + side of capacitor C1214. Adjust L1202 for 4 volts DC. Max. shutdown voltage (KV) 32 Note: Wait at least five minutes after the set has been turned on before making alignments. 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 disappears. · Connect a variable Resistor (1 MW) in parallel with RX3704, and decrease slowly the resistance value until shutdown occurs. · Measure High Voltage shutdown. 3828VD0205B 3-3 CH-FLAT - SERVICING SERVICING (continued) G2 ADJUSTMENT Use the following procedure when resetting G2. 1. Set Brightness and contrast in the Video menu to mid range. 2. Set color level minimum. 3. Connect the output of an NTSC generator to the antenna input on the receiver. 4. Select a color bar signal and turn color off. Adjust the G2 control so that the range of bar pattern start from completely withe (not overdriven) to black. Let visible 6 of 8 bars. 5. Return color level control to its normal setting. 6. Carefully observe which color is predominant on the CRT, Red, Green or Blue. Do not change the value of cutoff control of this color. 7. Adjust the other two cutoff controls to obtain color balance on the screen. 8. Select the color bars pattern from the Video generator and turn the chroma off. Check that the TV set displays 3/4 of gray scale from white to black. If black level is too high, readjust, register #27, RF 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. 3828VD0205B 3-4 CH-FLAT - SERVICING SERVICING (continued) 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.

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.
