14、of the fol-lowing:FIRE AND SHOCK HAZARD1. Be sure 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,s

15、train reliefs, power supply cords, and other hardware 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 certa

16、in to remove all loose foreign par-ticles.4. Check 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 wat

17、t or more. Lead tension around protruding metal 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

18、 of electrical shock. DO NOT USE A LINE ISOLATION 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,

19、conduit, etc.) and the exposed metal-lic parts, 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 exce

20、ed 0.75 volts RMS.This corresponds to 0.5 milliamp 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

21、heat duct, or in the path of heated air flow.2. 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 dec

22、orative scarves or other coverings thatmight obstruct 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 inspacer

23、s) to provide adequate air flow across the bottom. 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 secur

24、ed.6. Aproduct on a roll-about cart should be 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 f

25、rom a single outlet, can lead to disastrous conse-quences to home and family.A.C.

26、servicing the VCR + DVD RECODER cov-ered by this service data and its supplements and addends,read and follow the SAFETY PRECAUTIONS. NOTE: ifunforeseen circumstances create conflict between the fol-lowing servicing precautions and any of the safety precau-tions in this publications, always follow t

27、he safety precau-tions.Remember Safety First:General 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 electrica

28、lplug or other electrical connection.(3)Connecting 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

29、 or any of its assemblies.3.Unless specified otherwise 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, lubricatio

30、nof contacts is not required.4. Do not defeat 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

31、 installed.6.Always connect the test instrument 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 i

32、nsulation resistance meter (500V)to the blades 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,et

33、c.Electrostatically Sensitive (ES) DevicesSome 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 semic

34、onductor chip components.The following techniques 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 kn

35、ownearth ground. Alternatively, obtain and wear 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 condu

36、ctive surface such as aluminum foil, to prevent 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 el

37、ectrical charges sufficient to damage ES devices.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

38、ES devices are packaged withleads electrically 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 whi

39、ch thedevice will be installed.Caution: Be sure 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 lift

40、ingof your foot from a carpeted floor can generate static elec-tricity sufficient to damage an ES device.)1-4INFORMATION ABOUT LEAD-FREE SOLDERINGPhilips CE is producing lead-free sets from 1.1.2005 onwards. INDENTIFICATION:Regardless of special logo (not always indicated) one must treat all sets fr

41、om 1 Jan 2005 onwards, according next rules:Example S/N:Bottom line of typeplate gives a 14-digit S/N. Digit 5&6 is the year, digit 7&8is the week number, so in this case 1991 wk 18So from 0501 onwards = from 1 Jan 2005 onwardsImportant note: In fact also products of year 2004 must be treated in thi

42、s way as long as you avoid mixing solder-alloys(leaded/ lead-free). So best to always use SAC305 and the higher temperatures belong to this.Due to lead-free technology some rules have to be respected by the workshop during a repair: Use only lead-free solder alloy Philips SAC305 with order code 0622

43、 149 00106. If lead-free solder-paste is required,please contact the manufacturer of your solder-equipment. In general use of solder-paste within workshops should beavoided because paste is not easy to store and to handle. Use only adequate solder tools applicable for lead-free solder alloy. The sol

44、der tool must be able* To reach at least a solder-temperature of 400C, * To stabilize the adjusted temperature at the solder-tip * To exchange solder-tips for different applications. Adjust your solder tool so that a temperature around 360C 380C is reached and stabilized at the solder joint.Heating-

45、time of the solder-joint should not exceed 4 sec. Avoid temperatures above 400C otherwise wear-out of tipswill rise drastically and flux-fluid will be destroyed. To avoid wear-out of tips switch off un-used equipment, or reduceheat. Mix of lead-free solder alloy / parts with leaded solder alloy / parts is possible but PHILIPS recommends strongly toavoid mixed solder alloy types (leaded and lead-free). If o
