There are critical components used in LCD color TVs that are important for safety These components are identified with shading and. mark on the schematic diagrams and the electrical parts list It is essential that these critical parts be replaced only with the part number. specified in the electrical parts list to prevent electric shock fire or other hazard. NOTE Do not modify the original design without obtaining written permission from the manufacturer or you will void the original parts and. labor guarantee,USE CAUTION WHEN HANDLING THE LCD PANEL. When repairing the LCD panel be sure you are grounded by using a wrist band. When installing the LCD panel on a wall the LCD panel must be secured using the 4 mounting holes on the rear cover. To avoid damaging the LCD panel, do not press on the panel or frame edge to avoid the risk of electric shock. do not scratch or press on the panel with any sharp objects. do not leave the module in high temperatures or in areas of high humidity for an extended period of time. do not expose the LCD panel to direct sunlight, avoid contact with water It may cause a short circuit within the module. disconnect the AC adapter when replacing the backlight CCFL or inverter circuit. High voltage occurs at the inverter circuit at 650Vrms. always clean the LCD panel with a soft cloth material. use care when handling the wires or connectors of the inverter circuit Damaging the wires may cause a short. protect the panel from ESD to avoid damaging the electronic circuit C MOS. LEAKAGE CURRENT HOT CHECK CIRCUIT,KDL 22BX300 32BX300 3. KDL 22BX300 32BX300, The circuit boards used in these models have been processed using.
Lead Free Solder The boards are identified by the LF logo located. close to the board designation e g H1 etc see example The. servicing of these boards requires special precautions to be taken as. outlined below, It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints. Lead Free Solder is available under the following part numbers. Part number Diameter Remarks,7 640 005 19 0 3mm 0 25Kg. 7 640 005 20 0 4mm 0 50Kg,7 640 005 21 0 5mm 0 50Kg. 7 640 005 22 0 6mm 0 25Kg,7 640 005 23 0 8mm 1 00Kg. 7 640 005 24 1 0mm 1 00Kg,7 640 005 25 1 2mm 1 00Kg.
7 640 005 26 1 6mm 1 00Kg, Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics. For more information on the use of Lead Free Solder please refer to http www sony training com. KDL 22BX300 32BX300 4,KDL 22BX300 32BX300,SAFETY CHECK OUT. After correcting the original service problem perform the following The AC leakage from any exposed metal part to earth ground and. safety checks before releasing the set to the customer from all exposed metal parts to any exposed metal part having a. return to chassis must not exceed 0 5 mA 500 microamperes. 1 Check the area of your repair for unsoldered or poorly soldered Leakage current can be measured by any one of three methods. connections Check the entire board surface for solder splashes and. bridges 1 A commercial leakage tester such as the Simpson 229 or RCA. WT 540A Follow the manufacturers instructions to use these. 2 Check the interboard wiring to ensure that no wires are pinched or instructions. touching high wattage resistors, 2 A battery operated AC milliampmeter The Data Precision 245. 3 Check that all control knobs shields covers ground straps and digital multimeter is suitable for this job. mounting hardware have been replaced Be absolutely certain that. you have replaced all the insulators 3 Measuring the voltage drop across a resistor by means of a VOM. or battery operated AC voltmeter The limit indication is 0 75. 4 Look for unauthorized replacement parts particularly transistors V so analog meters must have an accurate low voltage scale. that were installed during a previous repair Point them out to the The Simpson s 250 and Sanwa SH 63TRD are examples of. customer and recommend their replacement passive VOMs that are suitable Nearly all battery operated digital. multimeters that have a 2 VAC range are suitable see Figure A. 5 Look for parts which though functioning show obvious signs of. deterioration Point them out to the customer and recommend their. How to Find a Good Earth Ground,replacement, A cold water pipe is a guaranteed earth ground the cover plate. retaining screw on most AC outlet boxes is also at earth ground If the. 6 Check the line cords for cracks and abrasion Recommend the retaining screw is to be used as your earth ground verify that it is at. replacement of any such line cord to the customer ground by measuring the resistance between it and a cold water pipe. with an ohmmeter The reading should be zero ohms, 7 Check the antenna terminals metal trim metallized knobs screws.
and all other exposed metal parts for AC leakage Check leakage as If a cold water pipe is not accessible connect a 60 to 100 watt. described below trouble light not a neon lamp between the hot side of the receptacle. and the retaining screw Try both slots if necessary to locate the hot. side on the line the lamp should light at normal brilliance if the screw. is at ground potential see Figure B,Leakage Test,To Exposed Metal.
