The service procedures recommended by Philips and described in this service manual are effective methods of performing service operations. S
5、ome 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 possibility exists that improper
6、 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 hazardous consequences of
7、 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 equipment will be jeopard
8、ized by the service method selected.

21、ily 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 that does not have the same safety characteristics as the recommended repla
22、cement part might create shock, fire, and/or other hazards. The Products Safety is under review continuously and new instructions are issued whenever appropriate. Prior to shipment from the factory, our products are carefully inspected to confirm with the recognized product safety and electrical cod
23、es of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced. Precautions during Servicing A. Parts identified by the # symbol are critical for safety. Replace only with pa
24、rt 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. Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking fil
25、ters, 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 especially: 1) Insulation tape 2) PVC tubing 3) Spacers 4) Insulators for transistors E.
26、 When replacing AC primary side components (transformers, power cord, etc.), wrap ends of wires securely about the terminals before soldering. F.Observe that the wires do not contact heat producing parts (heat sinks, oxide metal film resistors, fusible resistors, etc.). G. Check that replaced wires
27、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.Be careful that foreign objects (screws, solder droplets, etc.) do not remain inside the set. K.
28、 When connecting or disconnecting the internal connectors, first, disconnect the AC plug from the AC outlet. 1-2-2DVDN_ISP Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts, and wires have been returned to their or
29、iginal positions. Afterwards, do the following tests and confirm the specified values to verify compliance with safety standards. 1. Clearance Distance When replacing primary circuit components, confirm specified clearance distance (d) and (d) between soldered terminals, and between terminals and su
30、rrounding 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 specified (or lower) leakage current between B (earth ground, power cord plug prongs) and externa
31、lly exposed accessible parts (RF terminals, 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 below. Measuring Method (Power ON): Insert load Z between B (earth ground, power cord plug pro
32、ngs) and exposed accessible parts. Use an AC voltmeter to measure across the terminals of load Z. See Fig. 2 and the following table. Table 2: Leakage current ratings for selected areas Note:This table is unofficial and for reference only. Be sure to confirm the precise values. AC Line VoltageCleara

Then remove (glue will be melted). (Fig. S-1-6) 4.Release the flat
34、 pack-IC from the CBA using tweezers. (Fig. S-1-6) CAUTION: 1.The Flat Pack-IC shape may differ by models. Use an appropriate hot-air flat pack-IC desoldering machine, whose shape matches that of the Flat Pack-IC. 2.Do not supply hot air to the chip parts around the flat pack-IC for over 6 seconds b
35、ecause damage to the chip parts may occur. Put masking tape around the flat pack-IC to protect other parts from damage. (Fig. S-1-2) Fig. S-1-1 1-3-3DVDN_PC_SN 3.The flat pack-IC on the CBA is affixed with glue, so be careful not to break or damage the foil of each pin or the solder lands under the
36、IC when removing it. With Soldering Iron: 1.Using desoldering braid, remove the solder from all pins of the flat pack-IC. When you use solder flux which is applied to all pins of the flat pack-IC, you can remove it easily. (Fig. S-1-3) 2.Lift each lead of the flat pack-IC upward one by one, using a
37、sharp pin or wire to which solder will not adhere (iron wire). When heating the pins, use a fine tip soldering iron or a hot air desoldering machine. (Fig. S-1-4) 3.Bottom of the flat pack-IC is fixed with glue to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of th

(See Fig. S-1-7.) Be sure this mark matches the 1 on the PCB when positioning for installati
44、on. 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-conductors may occur due to a potential difference cause
45、d 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 sure to place a conductive sheet or copper plate with prop
46、er 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.
