The service procedures recommended by Philips and described in this service manual are effective methods of performing service operations. Some of these se

4、rvice 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 service methods

5、 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 each way. Conse

6、quently, 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 jeopardized by the serv

7、ice method selected.TABLE OF CONTENTSLASER BEAM SAFETY PRECAUTIONS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-1-1IMPORTANT SAFETY PRECAUTIONS. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

When checking the laser diode, be s

18、ure to keep your eyes at least 30 cm away from the pickup lens when the diode is turned on. Do not look directly at the laser beam.CAUTION: Use of controls and adjustments, or doing procedures other than those specified herein, may result in hazardous radiation exposure.Location: Inside Top of DVD m

20、ted 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 voltage, wattage, etc. Parts that have special safety characteristics are identified by a # on schematics and in parts l

21、ists. 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 Safety is under review continuously and new instructions are issued whenever appropriate. Prior to shipment from t

22、he 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 maintain such compliance, it is equally important to implement the following precautions when a set is being service

23、d.Precautions during ServicingA. 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

24、 specified replacements. Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.C. Use specified internal wiring. Note especially:1) Wires covered with PVC tubing2) Double insulated wires3) High voltage leadsD. Use specified insulating materials for hazardous

25、live parts. Note especially:1) Insulation tape2) PVC tubing 3) Spacers4) Insulators for transistorsE. 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 p

26、arts (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 been replaced, check that 5 - 6 kg of force in any direction will not loosen it.I. Also check areas surrounding repaired locations.

27、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, disconnect the AC plug from the AC outlet.1-2-2 DVDN_ISPSafety Check after ServicingExamine the area surrounding the repaired location f

28、or damage or deterioration. Observe that screws, parts, and wires have been returned to their original positions. Afterwards, do the following tests and confirm the specified values to verify compliance with safety standards.1. Clearance DistanceWhen replacing primary circuit components, confirm spe

29、cified clearance distance (d) and (d) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)Table 1: Ratings for selected areaNote: This table is unofficial and for reference only. Be sure to confirm the precise values.2. Leakage Current TestConfirm the specif

30、ied (or lower) leakage current between B (earth ground, power cord plug prongs) and externally 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 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. 2 and the following table.Table 2: Leakage current ratings for selected areasNote: This table is unoffic

32、ial and for reference only. Be sure to confirm the precise values.AC Line Voltage Clearance Distance (d), (d)120 V 3.2 mm (0.126 inches)AC Line Voltage Load Z Leakage Current (i) Earth Ground (B) to:120 V0.15 F CAP. when removing entire flat pack-IC, first apply soldering iron to center of the flat

33、pack-IC and heat up. Then remove (glue will be melted). (Fig. S-1-6)4. Release the flat 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

34、. 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 flat pack-IC to protect other parts from damage. (Fig. S-1-2)Fig. S-1-11-3-3 DVDN_PC_SN3. The flat pack-IC on the CBA is affixed with glue, so

35、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, 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 e

36、asily. (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 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 th

37、e 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)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 pi

38、ns 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 to 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

39、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 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

40、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 that 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 forc

Using desoldering braid, remove the solder from the foil of each pin of the 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 match

Ground for Human BodyBe 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 WorkbenchBe sure to place

45、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 cl
