16、AFETY 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 11.8 inches (30 cm) away from the pickup lens when the diode is turned on. Do not look directly a

17、t 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 to strike against your skin.

19、ecessarily 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 recommende

20、d 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 the factory, our products are carefully inspected to confirm with the recognized product safety and electri

21、cal 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 serviced. Precautions during Servicing A. Parts identified by the # symbol are critical for safety. Replace only

22、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 blocking capacitors, and noise block

23、ing 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) Spacers 4) Insulators for transis

24、tors E. 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

25、 wires do not contact sharp edges or pointed parts. H. When a power cord has been replaced, check that 1113 lb (56 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 insi

26、de the set. K. When connecting or disconnecting the internal connectors, first, disconnect the AC plug from the AC outlet. L.When reassembling, be sure to use the original screws or specified screws listed in the parts list. M. This unit is classified as a CLASS 1 LASER PRODUCT. 1-3-2BDN_ISP Safety

27、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 specified values to verify compliance with safety standards.

28、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 Note:This table is unofficial and for reference only. Be

29、 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 audio input and output terminals, microphone jacks, earph

30、one 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 the terminals of load Z. See Fig. 2 and the following tab

35、ve / Install Flat Pack-IC 1. Removal With 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 hot air. 3.Bottom of the

36、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 Flat Pack-IC shape

37、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 flat pack-IC t

38、o protect other parts from damage. (Fig. S-1-2) Top View OutIn Bottom View Input 5 10 Pin 1 Pin 1 FFC Cable Connector CBA * Be careful to avoid a short circuit. Fig. S-1-1 1-4-2BDN_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

39、 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 upw

40、ard 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 the CBA; when removing entire flat pack-IC, first apply solder

41、ing 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) 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

45、 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 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

46、replacement flat pack-IC more easily. 2.The “ I ” mark on the flat pack-IC indicates pin 1. (See Fig. S-1-7.) Be sure this mark matches the pin 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

48、 1-4-4BDN_SN 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 Human Body Be sure to wear a grounding band (1 M) that is properly grounded to

49、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-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.
