Before returning any television to the customer,the service technician must be sure that it is completely safe to operate without danger of electrical shock. X-RADIATION PRECAUTION The primary source of X-RADIATION in television receiver is the picture tube. The picture tube is specially constructed to limit X-RADIATION emissions. For continued X-RADIATION protection, the replacement tube must be the same type as the original including suffix letter. Excessive high voltage may produce potentially hazardous X-RADIATION. To avoid such hazards, the high voltage must be maintained within specified limit. Refer to this service manual, high voltage adjustment for specific high voltage limit. If high voltage exceeds specfied limits, take necessary corrective action. Carefully follow the instructions for +B1 volt power supply adjustment, and high voltage check to maintain the high voltage within the specified limits. PRODUCT SAFETY NOTICE Product safety should be considered when a component replacement is made in any area of a receiver. Components indicated by mark ! in the parts list and the schematic diagram designate components in which safety can be of special significance. It is particularly recommended that only parts designated on the parts list in this manual be used for component replacement designated by mark ! . No deviations fromresistance wattage or voltage ratings may be made for replacement items designated by mark ! . -2- -3- -4- -5- -6- -7- -8- Chassis Block Diagram -9- IC B lock D iagram IC 201 (LA7693*) -10PDF 文件使用 "pdfFactory" 试用版本创建 www.fineprint.com.cn IC B lock D iagram IC 702 & 802 (HEF 4052B) -11PDF 文件使用 "pdfFactory" 试用版本创建 www.fineprint.com.cn IC B lock D iagram IC500 (CQ0765) IC 301(LA7804* ) -12PDF 文件使用 "pdfFactory" 试用版本创建 www.fineprint.com.cn IC B lock D iagram IC 801 (LV1115) -13PDF 文件使用 "pdfFactory" 试用版本创建 www.fineprint.com.cn IC B lock D iagram IC 901 (LA42***) -14PDF 文件使用 "pdfFactory" 试用版本创建 www.fineprint.com.cn IC B lock D iagram IC 701(AN5832SA) -15PDF 文件使用 "pdfFactory" 试用版本创建 www.fineprint.com.cn Transistor Mark NPN PNP PNP L7809 INPUT B C E E C B E C C27 17 D2499 C18 15 E C B A1015 C21 20 C24 82 A966 E C B E C B NPN NPN PNP B B E C L7812 OUTPUT GND INPUT OUTPUT GND -16- L7805 INPUT OUTPUT GND Service Adjustments -20- Service Adjustments -21- Service Adjustments -22- Service Adjustments -23- Service Adjustments -24- Purity and Convergence Adjustment COLOR PURITY ADJUSTMENT (1) Before color purity adjustment,warm up the TV set over 15 minutes and fully degauss. (2) Receive pure white signal in AV status and set the TV receiver dynamic. (3) Go to factory mod MENU2. After write down the values of R-BIAS and B-BIAS, set the values of R-BIAS and B-BIAS zero. (4) Loosen the clamp screw of the deflection yoke and pull the deflection yoke towards color purity Magnetic loop. (5) Adjust color purity magnetic loop to make the green area at the center of CRT screen. (6) Slowly push the deflection yoke toward the front of CRT and set it where a uniform green field is obtained. Tighten the clamp screw of the deflection yoke. (7) Restore the values of R-BIAS,G-BIAS AND B-BIAS. CONVERGENCE ADJUSTMENT (1) Receive a dotted pattern. Set the TV receiver dynamic. (2) Loose the convergence magnet clamperrrrr and align red with blu dots at the center of the screen by rotating(R,B) static convergence magnets. (3) Align Red/Blue with green dots at the center of the screen by rotating(RB-G) static convergence magnet. (4) Remove the DY wedges and slightly tilt the deflection yoke horizontally and vertically to obtain the good overall convergnce. Fix them after the goob overall convergence got. (5) Fix purity error is found,follow PURITY ADJUSTMENT instructions. Purity Magnet RB-G Magnet Clamper Static Magnet -25- RB Control Location CONTROL LOCATION 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.

Insert the 2 UM4-AAA 1.5V batteries making sure the polarity (+ or -) of the batteries matches the polarity marks inside the unit. 3. Replace the battery cover. Replace with new batteries when the TV set begins to show the following symptoms: Operation is unsteady or erratic. Sometimes the TV set does not function with Remote Control Unit. Remark: 1) Alkaline Batterie Recommended 2) Remove batteries when they are exhausted or if the remote control is not to be used for a long time. THE CAUSES OF INTERFERENCE Incorporated in your TV receiver are the most upto-date devices to eliminate interference. Local radiation however, can create disturbances which visibly affect your picture. Proper installation, a good aerial are your best safe-guards against these disturbances. RF INTERFERENCE Moving ripples across the screen are caused by nearby transmitting or receiving-short-wave radio equipment. DIATHERMY Herringbone pattern and partial picture loss can result from the operation of diathermy equipment from a nearby doctor's surgery or hospital. SNOW Weak TV signals from long distant stations result in an instead picture and give the effect of falling snow. An antenna adjustment or antenna amplifier may be needed. GHOST Multiple image caused by TV signals reflected back from surrounding buildings, hills, aircraft, etc. is minimized by correct aerial positioning. CAR IGNITION Nearby cars and electrical motors can cause small streaks across the picture or make the picture roll. -35- Mechanica l Disassemblies CABINETBACKREMOVAL CHASSISREMOVAL 1.Refert o Figure 1,remove7screws. 2.Pulloffcabine t back andremove. 1.Removecabinetback. 2.Dischargethepicturetubeanode(2ndanodelead)tothe dagcoating(picturetubegroundinglead). 3.DisconnectDegaussingcoilsocket(KE),Picturetubesocket, D eflectionyokeconnector(KDY),Speakerconnectors(KL andKR),and2ndanodelead. 4.Removechassiscompletelybyslidingitstraightback.
