14、ST RISKOF FIRE, REPLACE ALLFUSES WITH THE SAME TYPE ANDRATING AS MARKED NEAR EACH FUSE.SERVICE INFORMATIONWhile servicing, use an isolation transformer for protection from AC line shock.After the original service problem has been corrected, make a check of the fol-lowing:FIRE AND SHOCK HAZARD1. Be s

15、ure that all components are positioned to avoid a possibility of adjacentcomponent shorts. This is especially important on items trans-ported to andfrom the repair shop.2. Verify that all protective devices such as insulators, barriers, covers, shields,strain reliefs, power supply cords, and other h

16、ardware have been reinstalledper the original design. Be sure that the safety purpose of the polarized lineplug has not been defeated.3. Soldering must be inspected to discover possible cold solder joints, soldersplashes, or sharp solder points. Be certain to remove all loose foreign par-ticles.4. C

17、heck for physical evidence of damage or deterioration to parts and compo-nents, for frayed leads or damaged insulation (including the AC cord), andreplace if necessary.5. No lead or component should touch a high current device or a resistor ratedat 1 watt or more. Lead tension around protruding meta

18、l surfaces must beavoided.6. After reassembly of the set, always perform an AC leakage test on allexposed metallic parts of the cabinet (the channel selector knobs, antennaterminals, handle and screws) to be sure that set is safe to operate withoutdanger of electrical shock. DO NOT USE A LINE ISOLAT

19、ION TRANS-FORMER DURING THIS TEST. Use an AC voltmeter having 5000 ohms pervolt or more sensitivity in the following manner: Connect a 1500 ohm, 10watt resistor, paralleled by a .15 mfd 150V AC type capacitor between aknown good earth ground water pipe, conduit, etc.) and the exposed metal-lic parts

20、, one at a time. Measure the AC voltage across the combination of1500 ohm resistor and .15 mfd capacitor. Reverse the AC plug by using anon-polarized adaptor and repeat AC voltage measurements for eachexposed metallic part. Voltage measured must not exceed 0.75 volts RMS.This corresponds to 0.5 mill

21、iamp AC. Any value exceeding this limit consti-tutes a potential shock hazard and must be corrected immediately.TIPS ON PROPER INSTALLATION1. Never install any receiver in a closed-in recess, cubbyhole, or closely fittingshelf space over, or close to, a heat duct, or in the path of heated air flow.2

22、. Avoid conditions of high humidity such as: outdoor patio installations wheredew is a factor, near steam radiators where steam leakage is a factor, etc.3. Avoid placement where draperies may obstruct venting. The customershould also avoid the use of decorative scarves or other coverings thatmight o

23、bstruct ventilation.4. Wall- and shelf-mounted installations using a commercial mounting kit mustfollow the factory-approved mounting instructions. Aproduct mounted to ashelf or platform must retain its original feet (or the equivalent thickness inspacers) to provide adequate air flow across the bot

24、tom. Bolts or screwsused for fasteners must not touch any parts or wiring. Perform leakage testson customized installations.5. Caution customers against mounting a product on a sloping shelf or in a tilt-ed position, unless the receiver is properly secured.6. Aproduct on a roll-about cart should be

25、stable in its mounting to the cart.Caution the customer on the hazards of trying to roll a cart with small cast-ers across thresholds or deep pile carpets.7. Caution customers against using extension cords. Explain that a forest ofextensions, sprouting from a single outlet, can lead to disastrous co

NOTE: ifunforeseen circumstances create conflict between the fol-lowing servicing precautions and any of the safety precau-tions in this publications, always follow the safety precau-tions.Remember Safety First:G

28、eneral Servicing Precautions1.Always unplug the VCR + DVD RECODER AC power cordfrom the AC power source before:(1)Removing or reinstalling any component, circuit board, module, or any other assembly.(2)Disconnecting or reconnecting any internal electricalplug or other electrical connection.(3)Connec

29、ting a test substitute in parallel with an elec-trolytic capacitor.Caution: A wrong part substitution or incorrect polarity installation of electrolytic capacitors may resultin an explosion hazard.2.Do not spray chemicals on or near this VCR + DVDRECODER or any of its assemblies.3.Unless specified o

30、therwise in this service data, cleanelectrical 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, lubricationof contacts is not required.4. Do not defeat

31、any plug/socket B+ voltage interlocks withwhitch instruments covered by this service manual mightbe equipped.5.Do not apply AC power to this VCR + DVD RECODERand / or any of its electrical assemblies unless all solid-state device heat sinks are correctly installed.6.Always connect the test instrumen

32、t ground lead to anappropriate ground before connecting the test instrumentpositive lead. Always remove the test instrument ground lead last.Insulation Checking ProcedureDisconnect the attachment plug from the AC outlet and turnthe power on. Connect an insulation resistance meter (500V)to the blades

33、 of the attachment plug. The insulation resis-tance between each blade of the attachment plug and acces-sible conductive parts (Note 1) should be more than 1M-ohm.Note 1: Accessible Conductive Parts include Metal panels,Input terminals, Earphone jacks,etc.Electrostatically Sensitive (ES) DevicesSome

34、 semiconductor (solid state) devices can be damagedeasily by static electricity. Such components commonly arecalled Electrostatically Sensitive (ES) Devices. Examples oftypical ES devices are integrated circuits and some fieldeffect transistors and semiconductor chip components.The following techniq

35、ues should be used to help reduce theincidence of component damage caused by static electricity.1.Immediately before handling any semiconductor compo-nent or semiconductor-equipped assembly, drain off anyelectrostatic charge on your body by touching a knownearth ground. Alternatively, obtain and wea

36、r a commer-cially 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 surface such as aluminum foil, to preven

37、t electrostatic charge buildup or exposure of the assembly.3.Use only a grounded-tip soldering iron to solder or unsolderES devices.4.Use only an anti-static solder removal device. Somesolder removal devices not classified as “anti-static” cangenerate electrical charges sufficient to damage ES devic

38、es.5.Do not use freon-propelled chemicals. These can generate an electrical charge sufficient to damage ESdevices.6.Do not remove a replacement ES device from its protec-tive package until immediately before you are ready toinstall it. (Most replacement ES devices are packaged withleads electrically

39、 shorted together by conductive foam,aluminum foil,or comparable conductive material).7.Immediately before removing the protective material fromthe leads of a replacement ES device, touch the protectivematerial to the chassis or circuit assembly into which thedevice will be installed.Caution: Be sur

40、e no power is applied to the chassis orcircuit, 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 the liftingof your foot from a carpeted floor can gene
