1. Precautions 1-1 Safety Precautions 1) Before returning an instrument to the customer, always make a safety check of the entire instrument, including, but not limited to, the following items: (1) Be sure that no built-in protective devices are defective or have been defeated during servicing. (1)Protective shields are provided to protect both the technician and the customer. Correctly replace all missing protective shields, including any removed for servicing convenience.
Precautions 2) Read and comply with all caution and safety related notes on or inside the cabinet, or on the chassis. 3) Design Alteration Warning-Do not alter or add to the mechanical or electrical design of this instrument. Design alterations and additions, including but not limited to, circuit modifications and the addition of items such as auxiliary audio output connections, might alter the safety characteristics of this instrument and create a hazard to the user.
Precautions 1-2 Servicing Precautions CAUTION : Before servicing units covered by this service manual and its supplements, read and follow the Safety Precautions section of this manual. Note : If unforseen circumstances create conflict between the following servicing precautions and any of the safety precautions, always follow the safety precautions. Remember: Safety First. 1-2-1 General Servicing Precautions (1) a.
Precautions 1-3 ESD Precautions Electrostatically Sensitive Devices (ESD) Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive Devices(ESD). Examples of typical ESD devices are integrated circuits and some field-effect transistors and semiconductor chip components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity.
Precautions 1-4 Handling the optical pick-up The laser diode in the optical pick up may suffer electrostatic breakdown because of potential static electricity from clothing and your body. WRIST-STRAP FOR GROUNDING 1M The following method is recommended. (1) Place a conductive sheet on the work bench (The black sheet used for wrapping repair parts.) (2) Place the set on the conductive sheet so that the chassis is grounded to the sheet.
Precautions 1-5 Pick-up disassembly and reassembly 1-5-1 Disassembly 1-5-2 Assembly 1) Remove the power cord. 2) Disassemble the Ass’y-DVD Deck. 3) Make solder land 3 points short on Pick-up FPC. (See Fig. 1-4) 4) Disassemble the Pick-up. 1) Replace the Pick-up. 2) Remove the soldering 3 points on Pick-up FPC. 3) Reassemble the Ass’y-DVD Deck. Note : If the assembly and disassembly are not done in correct sequence, the Pick-up may be damaged.
