10、NSThis BD player uses a pickup that emits a laser beam.The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure 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 o

13、ith 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 replacement part might create shock, fir

14、e, 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 codes of the countries in which they a

15、re 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 ServicingA. Parts identified by the # symbol are critical for safety. Replace only with part number specified.B. In addition to

16、 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 filters, etc.C. Use specified internal wi

17、ring. Note especially:1) Wires covered with PVC tubing2) Double insulated wires3) High voltage leadsD. Use specified insulating materials for hazardous live parts. Note especially:1) Insulation tape2) PVC tubing 3) Spacers4) Insulators for transistorsE. When replacing AC primary side components (tra

18、nsformers, 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 do not contact sharp edges or pointed parts.H. Wh

19、en 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. When connecting or disconnecting the internal connec

20、tors, first, disconnect the AC plug from the AC outlet.1-3-2BDN_ISPSafety Check after ServicingExamine 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

21、confirm the specified values to verify compliance with safety standards.1. Clearance DistanceWhen 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

22、selected areaNote:This table is unofficial and for reference only. Be sure to confirm the precise values.2. Leakage Current TestConfirm the specified (or lower) leakage current between B (earth ground, power cord plug prongs) and externally exposed accessible parts (RF terminals, antenna terminals,

23、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 prongs) and exposed accessible parts. Use an AC voltmeter to measure

24、 across the terminals of load Z. See Fig. 2 and the following table.Table 2: Leakage current ratings for selected areasNote:This table is unofficial and for reference only.

RemovalWith Hot-Air Flat Pack-IC Desoldering Machine:1.Prepare the hot-air flat pack-IC desoldering machine, then apply hot air to the Flat Pack-IC (about 5 to 6 seconds). (Fig. S-1-1)2.Remove the flat pack-IC with tweezers while applying the h

29、ot air.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-1-6)4.Release the flat pack-IC from the CBA using tweezers. (Fig. S-1-6)CAUTION:1.The

30、 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 because damage to the chip parts may occur. Put masking tape around

31、 the flat pack-IC to protect other parts from damage.

32、 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 easily. (Fig. S-1-3)2.Lift each lead of the flat pack-IC up

33、ward 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.
