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 Product’s 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 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 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 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) Insulators 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. 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. Be careful that foreign objects (screws, solder droplets, etc.) do not remain inside the set. K. Crimp type wire connector The power transformer uses crimp type connectors which connect the power cord and the primary side of the transformer. When replacing the transformer, follow these steps carefully and precisely to prevent shock hazards. Replacement procedure 1) Remove the old connector by cutting the wires at a point close to the connector. Important: Do not re-use a connector. (Discard it.) 2) Strip about 15 mm of the insulation from the ends of the wires. If the wires are stranded, twist the strands to avoid frayed conductors. 3) Align the lengths of the wires to be connected. Insert the wires fully into the connector. 4) Use a crimping tool to crimp the metal sleeve at its center. Be sure to crimp fully to the complete closure of the tool. L. When connecting or disconnecting the internal connectors, first, disconnect the AC plug from the AC outlet. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 6 DVD-1920/756 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. 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 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 sure to confirm the precise values. 2.

These characteristics often pass unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts that have these spe- cial safety characteristics are identified in this manual and its supplements; electrical components having such features are identified by the mark " ! " in the schematic diagram and the parts list. Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement parts that do not have the same safety characteristics as specified in the parts list may create shock, fire, or other hazards. Notes: 1. Do not use the part number shown on these draw- ings for ordering. The correct part number is shown in the parts list, and may be slightly different or amended since these drawings were prepared. 2. All resistance values are indicated in ohms (K=103, M=106). 3. Resistor wattages are 1/4W or 1/6W unless other- wise specified. 4. All capacitance values are indicated in µF (P=10-6 µF). 5. All voltages are DC voltages unless otherwise specified. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 32 DVD-1920/756 LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC DIAGRAMS ON THE FOLLOWING PAGES: 1.
