10、IONS 1-2-1B2NLBSP 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 turned on. Do not

11、 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 to strike aga

12、inst your skin. Drive Mechanism Assembly Laser Beam Radiation Laser Pickup Turntable 1-3-1BDN_ISP 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 protec

13、tion 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 characteristics a

14、s 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 the factory, our products are carefully inspected to confirm with the recognized product sa

15、fety 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 serviced. Precautions during Servicing A. Parts identified by the # symbol are critical for safet

16、y. 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 blocking capacitors,

17、 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) Spacers 4) Insula

18、tors for transistors 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. Che

19、ck 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.Be careful that foreign objects (screws, solder droplets, etc.) do not re

20、main inside the set. K. When connecting or disconnecting the internal connectors, first, disconnect the AC plug from the AC outlet. 1-3-2BDN_ISP Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts, and wires have bee

21、n returned to their original positions. Afterwards, do the following tests and confirm 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 soldered terminals, and be

22、tween terminals and surrounding 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 (earth ground, power cord pl

23、ug 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 below. Measuring Method (Power ON): Insert load Z between B (earth groun

24、d, 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 areas Note:This table is unofficial and for reference only. Be sure to confirm the precise values.

Removal With Hot-Air Flat Pack-IC Desoldering Machine: 1.Prepare the hot-air flat pack-IC desoldering machine, then app

29、ly 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 to center of the flat pack-IC and heat up.

30、 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.Do not supply hot

31、 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.

With Soldering Iron: 1.Using desoldering braid, remove the solder from all pins of the flat pack-IC. Wh

33、en 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 pins, use a fine tip soldering iron or a hot

34、 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.

(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 up

37、 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 me

(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 force

39、 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 “ I ” mark on the flat pack-IC indicates pin 1. (See Fig. S-1-7.) Be sure this mark matches the pin 1 on

40、 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 Air Blower Fig. S-1-5 Fine Tip Solderin
