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 400C 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.1-8WARNING! Use only the supplied speakers.The combination of the main unit and speakers provide the best sound.Using other speakers can damage theunit and sound quality will be negativelyaffected.Never makeor change connectionswith the power switched on.Connect the ACpower cord to thepower outlet only after you have finishedhooking up everything.Step 1:Connecting FM/MWantennasPlace the MW loop antenna on a shelf orattach it to a stand or wall. Extend the FM antenna and fix its ends to thewall. Adjust the position of the antennas foroptimal reception. Position the antennas as far as possible from aTV,VCR or other radiation source to preventunwanted noise.For better FM stereo reception, connectexternal FM antenna.MWConnectionsStep 2:Connecting the speakersConnect the speaker wires to the SPEAKERSterminals,right speaker to “R“ and left speaker to“L“,coloured (marked) wire to “+“ and black(unmarked) wire to “-“.Fully insert thestripped portion of the speaker wire into theterminal as shown.Helpful Hint: Ensure that the speaker cables are correctlyconnected. Improper connections may damage the system due to short-circuit.Do not connect more than one speaker to anyone pair of +/-speaker terminals.Step 3:Connecting the ACpower cord“AUTO INSTALL PRESS PLAY“ may appearon the displaypanel when the ACpower cord isplugged into the power outlet for the first time.PressÉÅon the main unit to store all availableradio stations or press Çto exit (refer to“Tuner Operations”).Step 4:Inserting batteries intothe remote control1321Open the battery compartment cover.2Insert two batteries type R06 or AA,followingthe indications (+-) inside the compartment.3Close the cover.Using the remote control to operatethe system1Aim the remote control directly at the remote sensor (iR) on the main unit.2Select the source you wish to control bypressing one of the source select keys on theremote control (for example CD, TUNER).3Then select the desired function (for example ÉÅ,í,ë).CAUTION!Remove batteries if they are exhaustedor will not be used for a long time.Do not use old and new or differenttypes of batteries in combination.
