25、servicing the DVD covered by this service data and its supplements and ADDENDUMS, read and follow the SAFETY PRECAUTIONS NOTE : if unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions in this publications, always follow the safety pre

26、cautions. Remember Safety First: General Servicing Precautions 1. Always unplug the DVD AC power cord from the AC power source before: (1) Removing or reinstalling any component, circuit board, module, or any other assembly. (2) Disconnection or reconnecting any internal electrical plug or other ele

27、ctrical connection. (3) Connecting a test substitute in parallel with an electrolytic capacitor Caution : A wrong part substitution or incorrect polarity installation of electrolytic capacitors may result in an explosion hazard. 2. Do not spray chemicals on or near this DVD or any of its assemblies.

28、 3. Unless specified otherwise in this service data, clean electrical contacts by applying an appropriate contact cleaning solution to the contacts with a pipe cleaner, cotton-tipped swab, or comparable soft applicator. Unless specified otherwise in this service data, lubrication of contacts is not

29、required. 4. Do not defeat any plug/socket B+ voltage interlocks with witch instruments covered by this service manual might be equipped. 5. Do not apply AC power to this DVD and/or any of its electrical assemblies unless all solid-state device heat sinks are correctly installed. 6. Always connect t

30、est instrument ground lead to the appropriate ground before connection the test instrument positive lead. Always remove the test instrument ground lead last. Insulation Checking Procedure Disconnect the attachment plug trom the AC outlet and turn the power on. Connect an insulation resistance meter(

31、500V) to the blades of the attachment plug. The insulation resistance between each blade of the attachment plug and accessible conductive parts (Note 1) should be more than 1M ohm. Note 1 : Accessible Conductive Parts including Metal panels, input terminals, Earphone jacks, etc. Electrostatically Se

32、nsitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and semiconductor chip com

33、ponents. The following techniques should be used to help reduce the incidence of component damage caused by static electricity. 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth gro

34、und. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surfa

35、ce such as aluminum toil, to prevent electrostatic charge buildup or exposure of the assembly. 3. Use only a GROUNDED-tip soldering iron to solder or unsolder ES devices. 4. Use only an anti-static solder removal device. Some solder removal devices not classified a anti-static can generate electrica

36、l charges sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charge sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES de

37、vices are packaged with leads electrically shorted together by conductive foam, aluminum foil, or comparable conductive material.) 7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into w

38、hich the device will be installed. Caution : Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Normally harmless motion such as the brushing together of your clothes fabric or

39、the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES device.) SERVICING PRECAUTIONS 1. POWER 2. STANDBY INDICATOR 3. DISC TRAY 4. OPEN/CLOSE 5.
