INFORMATION ABOUT LEAD-FREE SOLDERINGPhilips CE is producing lead-free sets from 1.1.2005 onwards.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 asyou avoid mixing solder-alloys (leaded/ lead-free). So best to always use SAC305 and thehigher 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 contactthe manufacturer of your solder-equipment. In general use of solder-paste within workshops should be avoided because paste is noteasy to store and to handle.

• Use only adequate solder tools applicable for lead-free solder alloy. The solder tool must be ableo To reach at least a solder-temperature of 40o To stabilize the adjusted temperature at the solder-tipo 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 thesolder-joint should not exceed ~ 4 sec. Avoid temperatures above 400 otherwise wear-out of tips will rise drastically and flux-fluidwill 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 mixedsolder 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-solderwith new solder alloy (SAC305).

• Use only original spare-parts listed in the Service-Manuals. Not listed standard-material (commodities) has to be purchased atexternal 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-freetemperature 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 againstmoisture. 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-partswill 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 wirebetween 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 theAC Power plug and the metal shielding of the tuner orthe aerial connection on the set. The reading should belarger than 4.5 Mohm (For U.S. it should be between4.2 Mohm and 12 Mohm).

4. Switch "off" the set, and remove the wire between thetwo 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 properfunction.

· 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 anyinner parts by the customer.

Repair Hints & Service Positions

1) During repair it is possible to disconnect the Tuner Boardand/or CD Module completely unless the fault is sus-pected to be in that area. This will not affect theperformance of the rest of the set.

Note: The flex cables are very fragile, care should be takennot to damage them during repair. After repair, bevery sure that the flex cables are inserted properlyinto the flex sockets before encasing, otherwise faultsmay occurs.
