3、 ServiceService ServiceService Service RadioFans.CN 收音机爱 好者资料库 IMPORTANT SAFETY NOTICE Proper service and repair is important to the safe, reliable operation of all Philips Equipment. The service procedures recommended by Philips and described in this service manual are effective methods of performi

4、ng service operations. Some of these service special tools should be used when and as recommended. It is important to note that this service manual contains various CAUTIONS and NOTICES which should be carefully read in order to minimize the risk of personal injury to service personnel. The possibil

5、ity exists that improper service methods may damage the equipment. It also is important to understand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. Philips could not possibly know, evaluate and advice the service trade of all conceivable ways in which service might be done or of the possible h

6、azardous consequences of each way. Consequently, Philips has not undertaken any such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not recommended by Philips must first use all precautions thoroughly so that neither his safety nor the safe operation of the e

7、quipment will be jeopardized by the service method selected.

20、 evi- dent from visual inspection, nor can the protection they give necessarily be obtained by replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteristics are identified by a ! on schematics and in parts lists. Use of a substitute replacement

21、 that does not have the same safety characteristics as the recommended replacement part might create shock, fire, and/or other hazards. The Products Safety is under review continu- ously and new instructions are issued whenever appropriate. Prior to shipment from the factory, our products are carefu

22、lly inspected to confirm with the recognized product safety and electrical codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally impor- tant to implement the following precautions when a set is being serviced. Precautions during Servicing A

23、. Parts identified by the ! symbol are critical for safety. Replace only with part number specified. B. In addition to safety, other parts and assemblies are specified for conformance with regulations applying to spurious radiation. These must also be replaced only with specified replacements. Examp

24、les: RF converters, RF cables, noise block- ing capacitors, and noise blocking filters, etc. C. Use specified internal wiring. Note especially: 1)Wires covered with PVC tubing 2)Double insulated wires 3)High voltage leads D. Use specified insulating materials for hazardous live parts. Note especiall

25、y: 1)Insulation tape 2)PVC tubing 3)Spacers 4)Insulators for transistors E. When replacing AC primary side components (transformers, power cord, etc.), wrap ends of wires securely about the terminals before solder- ing. F. Observe that the wires do not contact heat produc- ing parts (heatsinks, oxid

26、e metal film resistors, fus- ible resistors, etc.). G. Check that replaced wires do not contact sharp edges or pointed parts. H. When a power cord has been replaced, check that 5 - 6 kg of force in any direction will not loosen it. I.Also check areas surrounding repaired locations. J. Use care that

27、foreign objects (screws, solder drop- lets, etc.) do not remain inside the set. K. When connecting or disconnecting the internal connectors, first, disconnect the AC plug from the AC outlet. 1-2-2BDP_ISP Safety Check after Servicing Examine the area surrounding the repaired location for damage or de

28、terioration. Observe that screws, parts, and wires have been returned to their original positions. Afterwards, do the following tests and con- firm the specified values to verify compliance with safety standards. 1. Clearance Distance When replacing primary circuit components, confirm specified clea

29、rance distance (d) and (d) between sol- dered terminals, and between terminals and surround- ing metallic parts. (See Fig. 1) Table 1 : Ratings for selected area Note: This table is unofficial and for reference only. Be sure to confirm the precise values. 2. Leakage Current Test Confirm the specifie

30、d (or lower) leakage current between B (earth ground, power cord plug prongs) and externally exposed accessible parts (RF termi- nals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.) is lower than or equal to the specified value in the table bel

31、ow. Measuring Method (Power ON) : Insert load Z between B (earth ground, power cord plug prongs) and exposed accessible parts. Use an AC voltmeter to measure across the terminals of load Z.

(See Fig. S-1-7.) Be sure this mark

47、 matches the 1 on the PCB when positioning for installation. Then presolder the four corners of the flat pack-IC. (See Fig. S-1-8.) 3.Solder all pins of the flat pack-IC. Be sure that none of the pins have solder bridges. Instructions for Handling Semi- conductors Electrostatic breakdown of the semi

48、-conductors may occur due to a potential difference caused by electrostatic charge during unpacking or repair work. 1. Ground for Human Body Be sure to wear a grounding band (1 M) that is properly grounded to remove any static electricity that may be charged on the body. 2. Ground for Workbench Be s

49、ure to place a conductive sheet or copper plate with proper grounding (1 M) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing.
