10、SPECIFICATIONS 1-2-1B1.5P_LSP LASER BEAM SAFETY PRECAUTIONS This 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 turne

11、d 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 BD mechanism. Do not look directly at the laser beam coming from the pickup or allow it t

12、o strike against your skin. Drive Mechanism Assembly Laser Beam Radiation Laser Pickup Turntable 1-3-1BDP_ISP IMPORTANT SAFETY PRECAUTIONS Product Safety Notice Some electrical and mechanical parts have special safety-related characteristics which are often not evi- dent from visual inspection, nor

13、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 that does not have the same safety cha

14、racteristics 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 carefully inspected to confirm with the recog

15、nized 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. Parts identified by the ! symbol are

16、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. Examples: RF converters, RF cables, noise bl

17、ock- 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 especially: 1)Insulation tape 2)PVC tubing 3)Spa

18、cers 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, oxide metal film resistors, fus- ible resis

19、tors, 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 foreign objects (screws, solder drop- l

20、ets, etc.) do not remain inside the set. K. When connecting or disconnecting the internal connectors, first, disconnect the AC plug from the AC outlet. 1-3-2BDP_ISP Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts

21、, 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 clearance distance (d) and (d) between sol-

22、 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 specified (or lower) leakage current between B

23、(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 below. Measuring Method (Power ON) : Inser

24、t 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.

How to Remove / Install Flat Pack-IC 1. Removal With Hot-Air Flat Pack-IC Desoldering Machine: 1.Prepare the hot-air

29、 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 hot 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

30、 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 Flat Pack-IC shape may differ by models. Use an appropriate hot-air flat pack-IC desoldering machine, whose shape matches th

31、at 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 flat pack-IC to protect other parts from damage. (Fig. S-1-2) Top View OutIn Bottom View Input 5 10 Pin 1 Pin 1 FFC Cab

Fig. S-1-1 1-4-2DVDP_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, remove the

33、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 heating the

34、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-1-6) 4.Re

(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

37、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 to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of the flat pack

38、-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 that the flat pack-IC is not being held by glue. When the flat pack-IC is removed from the CBA, handle

39、 it gently because it may be damaged if force is applied. 2. Installation 1.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-

40、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.) 3.Solder all pins of the flat pack-IC. Be sure that none of the pins have solder bridges. To Solid Mounting Point Soldering Iron Iron Wire or Hot A
