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-fr

8、ee 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 abl

Adjust your solder tool so that a temperature around is reached and stabilized at the solder joint. Heating-time of the solder-joint should no

10、t exceed 4 sec. Avoid temperatures above 400otherwise 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 recomm

11、ends 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.

12、 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 B

13、GA-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 co

14、mmunicated 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.

Set the AC Power switch to the on position (keep the AC Power cord unplugged!). 3. Measure the resistance value between the pins of the AC Power plug and the metal shielding

17、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 ret

18、urned in its original condition. Pay in particular attention to the following points: Route the wire trees correctly and fix them with the mounted cable clamps. Check the insulation of the AC Power lead for external damage. Check the strain relief of the AC Power cord for proper function. Check the

19、electrical DC resistance between the AC Power Plug and the secondary side (only for sets which have a AC Power isolated power supply): Check the cabinet for defects, to avoid touching of any inner parts by the customer. 3-13-1 SET BLOCK DIAGRAM SET WIRING DIAGRAM 4-14-1 5-15-1 PCB LAYOUT - MAIN BOAR
