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 400°C, 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 360°C 380°C is reached and stabilized at the solder joint. Heating-time of the solder-joint should not exceed 4 sec. Avoid temperatures above 400°C otherwise wear-out of tips will rise drastically and fl ux-fl uid 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 profi le of the specifi c BGA (for de-soldering always use the lead-free temperature profi 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 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.

Dismantling of the loader to access the ESD protection point if necessary.2. Solder the ESD protection point*. 3. Disconnect fl exfoil cable from the defective loader.4. Put a paper clip on the fl exfoil to short-circuit the contacts (fi g.1) 5. Replace the defective loader with a new loader.6. Remove paperclip from the fl exfoil and connect it to the new loader.7. Remove solder joint on the ESD protection point.ATTENTION: The laser diode of this loader is protected against ESD by a solder joint which shortcircuits the laserdiode to ground. For proper functionality of the loader this solder joint must be remove after connection loader to the set.Type 1 Type 2(ESD protection point is accessible from top of loader) (ESD protection point is accessible from bottom of the loader)*Only applicable for defective loader needed to be sent back to supplier for failure analysis and to support backcharging evidence.This is also applicable for all partnership workshops.EN 93139 785 31590Directions for Use 3.DVD HOME THEATRE SYSTEMHTS3455Quick Start GuideConnect Set up Enjoy1 2 3Whats in the box?DVD system Remote Controland 2 batteriesUser ManualComposite video cable1 centre, 2 front,2 rear speakersand AV subwooferFM wire antennaAM/MW loop antennaInter-connect cable2 Power cables1ConnectA PlacementProper speakers system placement is important to ensure optimum sound performance.ABCCDDAPlace the centre speaker above or close to the TV.BPlace the subwoofer on the floor, at least one metre away from the TV.CPlace the front speakers at equal disctances from the TV.DPlace the rear speakers at normal listening ear level.B Connect the radio antennasKeep the antennas away from the electronic devices to prevent unwanted interference.RL12 mmABCAConnect the FM antenna to the FM socket.
