The service procedures recommended by Philips and described in this service manual are effective methods of performing ser
4、vice 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 possibility ex
5、ists 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 hazardo
6、us 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 equipme
7、nt will be jeopardized by the service method selected.

20、P IMPORTANT SAFETY PRECAUTIONS Product Safety Notice Some electrical and mechanical parts have special safety-related characteristics which are often not evident from visual inspection, nor can the protection they give necessarily be obtained by replacing them with components rated for higher voltag
21、e, 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 replacement part might create shock, fire, and/or other hazards. The Products
22、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 codes of the countries in which they are to be sold. However, in order to ma
23、intain 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 part number specified. B. In addition to safety, other parts and assemblies
24、 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 filters, etc. C. Use specified internal wiring. Note especially: 1) Wires co
25、vered 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. When replacing AC primary side components (transformers, power cord, etc
26、.), 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 do not contact sharp edges or pointed parts. H. When a power cord has bee
27、n 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. When connecting or disconnecting the internal connectors, first, disconn
28、ect 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 original positions. Afterwards, do the following tests and confirm the spec
29、ified 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 surrounding metallic parts. (See Fig. 1) Table 1: Ratings for selected area
30、 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 externally exposed accessible parts (RF terminals, antenna terminals, video and
31、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 prongs) and exposed accessible parts. Use an AC voltmeter to measure across
32、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 VoltageClearance Distance (d), (d) 120 V 3.2 mm (0.126 inches) AC Line VoltageLoad ZLe

(Fig. S-1-6) 4.Release the flat pack-IC from the CBA using tweezers. (Fig. S-1-6) CAUTION: 1.The Flat Pa
34、ck-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 because damage to the chip parts may occur. Put masking tape around the fl
35、at 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 IC when removing it. With Soldering Iron: 1.Using desoldering braid, remo
36、ve 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 sharp pin or wire to which solder will not adhere (iron wire). When heati
37、ng 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 the flat pack-IC and heat up. Then remove (glue will be melted). (Fig. S-1-
38、6) 4.Release the flat pack-IC from the CBA using tweezers. (Fig. S-1-6) With Iron Wire: 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.Affix the wire t
39、o a workbench or solid mounting point, as shown in Fig. S-1-5. 3.While heating the pins using a fine tip soldering iron or hot air blower, pull up the wire as the solder melts so as to lift the IC leads from the CBA contact pads as shown in Fig. S-1-5. 4.Bottom of the flat pack-IC is fixed with glue
40、 to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of the flat pack-IC and heat up. Then remove (glue will be melted). (Fig. S-1-6) 5.Release the flat pack-IC from the CBA using tweezers. (Fig. S-1-6) Note: When using a soldering iron, care must be taken to ensure t
41、hat the flat pack-IC is not being held by glue. When the flat pack-IC is removed from the CBA, handle it gently because it may be damaged if force is applied.

Installation 1.Using desoldering braid, remove the solder from the foil of each pin of the
43、 flat pack-IC on the CBA so you can install a replacement flat pack-IC more easily. 2.The “” mark on the flat pack-IC indicates pin 1. (See Fig. S-1-7.) Be sure this mark 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.
44、) 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 caused by electrostatic charge during unpacking or repair work. 1. Ground for
45、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 proper grounding (1 M) on the workbench or other surface, where the semi-cond
46、uctors 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.
