IDENTIFICATION: Regardless of special logo (not always indicated) one must treat all sets 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 the week number, so in this case 2005 wk12 So from 0501 onwards = from 1 Jan 2005 onwards Important note: In fact also products of year 2004 must be treated 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 code 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 be avoided because paste is not easy to store and to handle. Use only adequate solder tools applicable for lead-free solder alloy. The solder tool must be able o To reach at least a solder-temperature of 40 o To stabilize the adjusted temperature at the solder-tip o To exchange solder-tips for different applications. Adjust your solder tool so that a temperature around is reached and stabilized at the solder joint. Heating-time of the solder-joint should not exceed 4 sec. Avoid temperatures above 400 otherwise wear-out of tips will 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 alloy / parts is possible but PHILIPS recommends strongly to avoid mixed 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 alloy and re-solder with new solder alloy (SAC305). Use only original spare-parts listed in the Service-Manuals. Not listed standard-material (commodities) has to be purchased 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 the lead-free temperature profile, 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 the IC against moisture. After opening, dependent of MSL-level seen on indicator-label in the bag, the BGA-IC possibly still has to be baked dry. (MSL=Moisture Sensitivity 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, all needed spare-parts will be available till the end of the service-period. For repair of such sets nothing changes. On our website www.atyourservice.ce.Philips.com you find more information to: BGA-de-/soldering (+ baking instructions) Heating-profiles of BGAs and other ICs used in Philips-sets You will find this and more technical information within the “magazine“, chapter “workshop news“. For additional questions please contact your local repair-helpdesk. SERVICE INSTRUCTION 1. Unplug the AC Power cord and connect a wire between the two pins of the AC Power plug.2. Set the AC Power switch to the “on“ position (keep theAC Power cord unplugged!).3. Measure the resistance value between the pins of the AC Power plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be larger than 4.5 Mohm (For U.S. it should be between 4.2 Mohm and 12 Mohm).4. Switch “off“ the set, and remove the wire between the two pins of the AC Power plug.Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention tothe following points:· Route the wire trees correctly and fix them with themounted cable clamps.· Check the insulation of the AC Power lead for externaldamage.· Check the strain relief of the AC Power cord for proper function.· Check the electrical DC resistance between the AC PowerPlug and the secondary side (only for sets which have a ACPower isolated power supply): Check the cabinet for defects, to avoid touching of any inner parts by the customer.1-8INSTALLATIONInstallationIMPORTANT!The type plate is located at the rear ofthe system. Before connecting the ACpower cordto the wall outlet,ensure that all otherconnections have been made.Never make or change anyconnections with the power switched on.High voltage! Do not open.You run therisk of getting an electric shock.The machine does not contain anyuser-serviceable parts.Modification of the product couldresult in hazardous radiation of EMC orother unsafe operation.Toavoid overheating of the system,a safetycircuit has been built in.Therefore,yoursystem may switch to Standby modeautomatically under extreme conditions.Ifthis happens,let the system cool downbefore reusing it(not available for all versions).Note: Before installation is finished,it is notrecommended to remove the protective plastic filmattached to the surface of the front panel to avoidany scratch caused during installation.AUDIO INS-VIDEO IN VIDEO INTV INAUDIO INS-VIDEOINVIDEO INTV INACpower cordSpeaker(right)Speaker(left)FM wire antennaStep 2:FM antenna connectionConnect the supplied FM antenna to the FMAERIALterminal.Fully extend and adjust theposition of the antenna for optimal reception.For better FM stereo reception, connect an outdoor FM antenna to the FM AERIAL (FMANTENNA) terminal.Notes: This system does not support MW reception.InstallationStep 1:Connecting speakers1Place the main set with the front side facing down on a flat and firm surface.Then removethe detachable cover on the back of the set toexpose the terminals available for connection.2Connect the two front speaker cables to theSPEAKER OUTterminals:right speaker to “R“and left speaker to “L“.3Connect one end of the 15-pin D-Sub cable(the other end is fixed on the CONNECT TOSUBWOOFERterminal on the back of themain set) to the CONNECT TO MAINterminal of the subwoofer by matching the pins.Fix the two screws on the connectors to ensurefirmconnection.Notes: Ensure that the speaker cables are correctlyconnected.Improper connections may damage thesystem due to short-circuit.For optimal sound performance, use thesupplied speakers.Do not connect more than one speaker to anyone pair of +/- speaker terminals.Do not connect speakers with an impedancelower than the speakers supplied.Please refer tothe SPECIFICATIONS section of this manual.1-9INSTALLATIONInstallationStep 3:Connecting TVIMPORTANT!You only need to make one videoconnection from the following options,depending on the capabilities of your TV.Connect the DVD system directly tothe TV.Using AV OUT jackAUDIO INS-VIDEO IN VIDEO INTV INAUDIO INS-VIDEOINVIDEO INTV IN1Connect the end of the supplied AVcord withonly one connector to the AVOUTjack of theDVD system.2For the other end, connect the video output connector (yellow) to the video input jack (orlabeled as A/ V In,CVBS,Composite orBaseband) on the TV. To hear the sound of thisDVD system through your TV, connect the audioconnectors (white/ red) to the audio input jackson the TV.Using the video boxIMPORTANT!ASCART connection will let you usefeatures both Audio and Video on theDVD Player.The supplied video box provides you with moreTV connection options.
