18、RVICING GUIDELINES FOR DVD+VCR PRODUCTS1-4SERVICING PRECAUTIONSCAUTION: Before servicing the VCR+DVD covered by thisservice data and its supplements and addends, read andfollow the SAFETY PRECAUTIONS. NOTE: if unforeseencircumstances create conflict between the following servicingprecautions and any

19、 of the safety precautions in thispublications, always follow the safety precautions.Remember Safety First :General Servicing Precautions1.Always unplug the VCR+DVD AC power cord from the ACpower source before:(1) Removing or reinstalling any component, circuit board,module, or any other assembly.(2

20、) Disconnecting or reconnecting any internal electricalplug or other electrical connection.(3) Connecting a test substitute in parallel with anelectrolytic capacitor.Caution : A wrong part substitution or incorrect polarityinstallation of electrolytic capacitors may result in anexplosion hazard.2.Do

21、 not spray chemicals on or near this VCR+DVD or any ofits assemblies.3.Unless specified otherwise in this service data, cleanelectrical contacts by applying an appropriate contactcleaning solution to the contacts with a pipe cleaner, cotton-tipped swab, or comparable soft applicator. Unless specifie

22、d otherwise in this service data, lubrication ofcontacts is not required.4.Do not defeat any plug/socket B+ voltage interlocks withwhich instruments covered by this service manual might beequipped.5.Do not apply AC power to this VCR+DVD and/or any of itselectrical assemblies unless all solid state d

23、evice heat sinksare correctly installed.6.Always connect the test instrument ground lead to anappropriate ground before connecting the test instrumentpositive lead. Always remove the test instrument groundlead last.Insulation Checking ProcedureDisconnect the attachment plug from the AC outlet and tu

24、rnthe power on. Connect an insulation resistance meter (500V)to the blades of the attachment plug. The insulation resistancebetween each blade of the attachment plug and accessibleconductive parts (Note 1) should be more than 1Mohm.Note 1: Accessible Conductive Parts include Metal panels,Input termi

25、nals, Earphone jacks,etc.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 field effe

26、cttransistors and semiconductor 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 componentor semiconductor-equipped assembly, drain off anyelectrostatic charge on your

27、body by touching a known earthground. Alternatively, obtain and wear a commerciallyavailable discharging wrist strap device, which should beremoved for potential shock reasons prior to applying powerto the unit under test.2.After removing an electrical assembly equipped with ESdevices, place the ass

28、embly on a conductive surface suchas aluminum foil, to prevent electrostatic charge buildup orexposure 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. Some solderremoval devices not classified as “anti-static”

29、can generateelectrical charges sufficient to damage ES devices.5.Do not use freon-propelled chemicals. These can generatean electrical charge sufficient to damage ES devices.6.Do not remove a replacement ES device from its protectivepackage until immediately before you are ready to install it.(Most

30、replacement ES devices are packaged with leadselectrically shorted together by conductive foam, aluminumfoil,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 assem

31、bly into which 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 unpackagedreplacement ES devices. (Normally harmless motion suchas the brushing together of your clothes fabric o

32、r the liftingof your foot from a carpeted floor can generate staticelectricity sufficient to damage an ES device.)1-5INFORMATION 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 s

33、ets from 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&8 is theweek 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

34、in this 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 cod

35、e 0622 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. T

36、he solder 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.He

37、ating-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 reduce heat. Mix of lead-free solder alloy / parts with leaded solder all

38、oy / parts is possible but PHILIPS recommends strongly to avoidmixed solder alloy types (leaded and lead-free).If one cannot avoid or does not know whether product is lead-free, clean carefully the solder-joint from old solder alloyand re-solder with new solder alloy (SAC305). Use only original spar

39、e-parts listed in the Service-Manuals. Not listed standard-material (commodities) has to bepurchased at external companies. Special information for BGA-ICs:- always use the 12nc-recognizable soldering temperature profile of the specific BGA (for de-soldering always use thelead-free temperature profi

40、le, in case of doubt)- lead free BGA-ICs will be delivered in so-called dry-packaging (sealed pack including a silica gel pack) to protect theIC against moisture. After opening, dependent of MSL-level seen on indicator-label in the bag, the BGA-IC possibly stillhas to be baked dry. (MSL=Moisture Sen

41、sitivity Level). This will be communicated via AYS-website.Do not re-use BGAs at all. For sets produced before 1.1.2005 (except products of 2004), containing leaded solder-alloy and components, allneeded spare-parts will be available till the end of the service-period. For repair of such sets nothin
