13、e Some electrical and mechanical parts have special safety-related 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 cha

14、racteristics 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, fire, and/or other hazards. The Products Safety is under review continuously and new instruc

15、tions 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 are to be sold. However, in order to maintain such compliance, it is equally important to

16、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 with part number specified. B. In addition to safety, other parts and assemblies are specified for conformance with regulations app

17、lying 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 wiring. Note especially: 1) Wires covered with PVC tubing 2) Double insulated wires 3)

18、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 transistors E. When replacing AC primary side components (transformers, power cord, etc.), wrap ends of wires securely about the terminals

19、 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. When a power cord has been replaced, check that 5 - 6 kg of force in any dir

20、ection 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 connectors, first, disconnect the AC plug from the AC outlet. L.When reassemb

21、ling, be sure to use the original screws or specified screws listed in the parts list. 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 been returned to their original positions. After

22、wards, 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 between terminals and surrounding metallic part

23、s. (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 plug prongs) and externally exposed accessible

24、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 ground, power cord plug prongs) and exposed access

25、ible parts. Use an AC voltmeter to measure across the terminals of load Z. See Fig. 2 and the following table.

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

30、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. Then remove (glue will be melted). (Fig. S-1

31、-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 air to the chip parts around the flat pack-I

32、C 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. When you use solder flux which is applied to al

34、l 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 air desoldering machine. (Fig. S-1-4) 3.Bott

(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 the wire as the solder melts so as to lift t

38、he 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 melted). (Fig. S-1-6) 5.Release the flat pack-I

39、C 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 force is applied. 2. Installation 1.Using desolder

40、ing 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 the PCB when positioning for installation. T
