Box 240007 Huntsville, Al 35824 Copyright© May 2005 by Zenith Electronics Corporation Printed in U.S.A. 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. 0.16uF 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. Good Earth Ground such as the Water Pipe, Conduit, etc. 1600 OHM 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. Place this probe on each exposed metal part. 10 WATT 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. 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. The exclamation point within an equilateral triangle is intended to alert the service personnel to important safety information in the service literature. 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. 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. 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. Graphic symbols 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. IMPLOSION 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. FIRE AND SHOCK HAZARD 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. TIPS ON PROPER INSTALLATION 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. 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. Soldering must be inspected to discover possible cold solder joints, solder splashes, or sharp solder points. Be certain to remove all loose foreign particles. 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. 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. 4. 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. 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. 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. 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. i PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS X-Radiation To prevent possible exposure to x-radiation caused by excessive CRT anode voltage, the CL 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 anode Voltage Shutdown Circuit Operation (Refer to Figure below) The flyback pulse voltage from pin 6 of TX3204 (Flyback Transformer) is peak detected (rectified) by the action of diode DX3006 and capacitor CX3003. This forms a DC voltage appearing on CX3003 representative of the CRT anode voltage (HV) produced by TX3204. This voltage is divided down by precision resistors RX3013, RX3015, RX3016 and RX3022. This lower voltage appears on the zener diode ZDX3004; 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 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). ·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. 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. ·Connect a variable Resistor (1 MW) in parallel with RX3704, and decrease slowly the resistance value until shutdown occurs. ·Measure High Voltage shutdown.

These jacks can be used to view videotapes from a VCR or Camcorder. When the video cable is plugged into the jack, the shorting jumper J1 opens, placing a high at pin 10 of the IC6000 microprocessor. 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 switching into tuner mode until the video cable is disconnected. All this is made possible by the new technology that is being built into these receivers. The SuperPort and Multiple Protocol Interface (MPI) jack and associated circuitry allow remote control of the set. MULTIPLE PROTOCOL INTERFACE Television functions and features are controlled by the communication of commands and status information through a SuperPort by the MPI interface. EBC (EDGE BOARD CONNECTOR) Allows easy access for removing/installing accessory modules providing a rail mounted slide-through card. These cards might contain one of the above features. SUPERPORT - MPI Zenith Commercial Product receivers are now being adapted to interact with other equipment. Prime examples of this can be found in Lodging and Health Care situations where the set is controlled from the main office.

(Blocks signals from VCRs, DVD players, etc. connected to the TV Audio/ Video input jacks). You could also leave AUX SOURCES unblocked, and then choose allowable ratings. PARENTAL CONTROL This optional feature can be used to prevent (block) unwanted programming from appearing on your TV. In the CONTENT BLK option, you can block program Content based on individual parameters such as Strong Dialog, Bad Language, Sex Scenes, Violence Scenes, or Fantasy Violence Scenes. PARENTAL CONTROL offers the user a wide variety of options and settings that restrict or block programming that can appear on the TV. PARENTAL CONTROL allows users the capability of defining which program ratings they consider acceptable to younger or more sensitive viewers. You can set PARENTAL CONTROL to be active in the SET HOURS option for up to 12 hours. Use the number keys on the remote to select a secret password in the SET PASSWORD option. PARENTAL CONTROL can be preset and turned on or off by a user who specifies the 4 number password. The number of hours blocked must also be specified. Don’t forget the password, as it is the only way you can access the PARENTAL CONTROL menu and change rating selections or turn PARENTAL CONTROL off. General audience and children viewer blocks can both be programmed into the TV’s memory. Viewer ratings are specified for both the TV industry and the motion picture industry; both rating systems can be used. The ratings are based mainly on children’s ages. If you do not want PARENTAL CONTROL to be active all the time, you can turn it on or off with the LOCK ON/ OFF option. Notes: You can set different PARENTAL CONTROL viewing restrictions for general audiences and for children - both can be active at the same time. Simply specifying one content block such as Sex Scenes, will not automatically block another type of content in the programs from appearing. Even if you choose to leave the AUX INPUTS unblocked, the ratings you specify will automatically restrict the programming that appears from the video sources. You cannot disable PARENTAL CONTROL by disconnecting the TV from power. Block hours will automatically reset to the original block time setting specified if power is disconnected. To reset the password, use the installer’s remote control to deactivate the V-Chip in the Installer’s menu (#21). Exit out of the Installer’s Menu after deactivating the Parental Control. Then enter back in and reactivate the V-Chip.

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. 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. Check the following: Keyboard input at IC6000 pins 7 and 8 IR input at IC6000 pin 15 Power On output at IC6000 pin 32 Check the switched voltages: +9 VSW DC at CX3811 +14 VAUD DC for the Audio Amp at 2X3510 +8 VSW DC CX3831 SWEEP DERIVED VOLTAGES +28 volts DC at (+) CX2114 +35 volts DC at the junction of CX3253 and DX3252 +215 volts DC at the junction of CX3208 and RX3208 +33 volts DC at the junction of RX3216 and ZD6001 MODULE-LEVEL SERVICING The CL Chassis is Module Level repair only. Replacement modules are available on an exchange basis. If the CRT or Video processor IC are 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. CRT FILAMENT Check at pin 3 and 4 of connector CN2C5A. This should read voltages between 6.0 and 6.4 volts AC on a true RMS meter. 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 24 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 from micro (IC6000) at pin 15 G in from micro (IC6000) at pin 16 B in from micro (IC6000) at pin 17 WARNING! DO NOT disconnect the Video output module from the CRT when troubleshooting 32” receivers. If the video output module is removed on these sets while power is ON, the CRT will arc and can be permanently damaged. Also, the technician is in danger of serious shock. There is a termination circuit (W5101) on the CRT module to prevent this from happening. SERVICING THE POWER SUPPLY Check the standby voltages first: +VM at CX3415 (usually 169.7 VDC when 120 VCA) B+ at CX3801 Note: B+ 124 VDC for 32” & 27”, B+ 126 VDC for 25” and B+ 120 VDC for 19” & 20”.

SYNC at pin 1, Vertical SYNC at pin 2 R Out at pin 52, G Out at pin 51 and B Out at pin 50 (Refer to figure below) The flyback pulse voltage from pin 6 of TX3204 (flyback transformer) is peak detected (rectified) by the action of the diode DX3006 and capacitor CX3003. This is from a DC voltage appearing on CX3003 representative of the CRT anode voltage (HV) produced by TX3204. Precision resistors RX3013, RX3015, RX3016, and RX3022 divide this voltage down. This lower voltage appears on the input (QX3002 collector) of a comparator circuit formed by RX3008, ZDX3004, QX3002, RMX3009, CX3004, QX3001, RMX3017 and RMX3021. In the event the CRT anode voltage becomes excessive, the comparator output (QX3001 emitter) will go to high level, at approximately 5 volts. This signal (SHUTDOWN) is sent to pin 4 of IC6000 (microprocessor), and used to turn off the TV set. VERTICAL CIRCUIT Check the following at ICX2100: Vertical drive at pin 4. Vertical out at pin 2. +28 VDC at pin 6. HORIZONTAL CIRCUIT CRT ANODE HIGH VOLTAGE MEASUREMENT PROCEDURE Check the following: Horizontal drive to base of Q3201 predriver. Driver transformer output at base of QX3203. Shutdown voltage at RM6009. Each CRT screen size has its own safe operating anode and shutdown voltage. Critical safety component (designated with and 'X' in the component designator) are designed to operate the CRT at a safe operating anode voltage and provide proper shutdown thresholds.

SR25-3828VD0171B 3-4 CL - SERVICING SERVICE ADJUSTMENTS (continued) SWITCHING PROCESS Close caption is achieved by taking a signal from the YSW-OUT pin (31) of the video processor. Video switching is done between the CV inputs and the Y/C inputs. There are three CV signals to consider: SENSING AND PRIORITIES CAMPORT VIDEO enters at pin 7 of IC2901. REAR VIDEO enters at pin 5 of IC2901. IF Video enters at TV pin 12 of IC2901. CL-Series 34 & 39 models do not have a source menu. Software sensing the inputs based on their priorities does switching between sources. The camport input always has first priority, it is sensed directly through the microprocessor. The S-Video input has the second level. The Y/C connector does the SVideo sensing. The third level corresponds to rear video and antenna signal (RF), they would be selected by remote control. These signals exit from VOUT1 (pin 11) to be processed and returned to the switch as Y/C signals (Y-COMB and IC2902). The second part of the switching is between: Y/C COMB signals enter at pins 10 and 7 of IC2902 and Y/C EXT signals entering at pins 12 & 5 of IC2902. The selected Y/C signals exit from pins 11 & 8 to be sent to the video processor as main signals.

Allow the receiver to warm up for 15 to 20 minutes. 1. Release locking assembly. 2. Degauss the CRT. 2. Connect crosshatch generator to the receiver and adjust static (center) convergence as follows: 3. Connect a crosshatch generator to the receiver and “rough in” the static (center) convergence. Follow the Convergence Procedure. 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 top-dead-center position to converge the red and blue lines vertically. 4. Adjust for best focus. 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. 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. Using a crosshatch generator capable of producing individual fields, adjust the generator to produce a red field. Use the purity tabs to center a red stripe. 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 (P/N 949-00050). 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. 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. 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. Note: 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. 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.
