INFORMATION ABOUT LEAD-FREE SOLDERING

Philips 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:

• 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

• Adjust your solder tool so that a temperature around

• Mix of lead-free solder alloy / parts with leaded solder alloy / parts is possible but PHILIPS recommends strongly to avoid mixed

• Use only original spare-parts listed in the Service-Manuals. Not listed standard-material (commodities) has to be purchased at

• Special information for BGA-ICs:

• For sets produced before 1.1.2005 (except products of 2004), containing leaded solder-alloy and components, all needed spare-parts

• On our website www.atyourservice.ce.Philips.com

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.

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.

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).

external companies.

- 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.

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

Im portant note 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:

: In fact also product s of year 2004 must be treated in this way as long as

For additional questions please contact your local repair-helpdesk.

You will find this and more technical information within the "magazine", chapter "workshop news".

SERVICE INSTRUCTION

Safety regulations require that after a repair, the set must be returned 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 electrical DC resistance between the AC Power Plug and the secondary side (only for sets which have a AC Power isolated power supply):

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 the AC 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.

• Check the cabinet for defects, to avoid touching of any

inner parts by the customer.

MAINTENANCE AND TROUBLESHOOTING

Solution

Troubleshooting

If the signal is too weak, adjust the antenna or

connect an external antenna for better

reception.

Increase the distance between the Mini HiFi

System and your TV or VCR.

Clean deck parts, see “Maintenance”.

Use only normal (IEC I) tape for recording.

Remove and reconnect the AC power plug and

switch on the system again.

Adjust the volume.

Check that the speakers are connected correctly.

Check if the stripped speaker wire is clamped.

Check the speaker connections and location.

Select the source (CD or TUNER, for example)

before pressing the function button ( , 4 /

¢ ).

Reduce the distance between the remote

control and the system.

Insert the battery with its polarities (+/– signs)

aligned as indicated.

Replace the battery.

Point the remote control directly toward

REMOTE SENSOR sensor on the front of the

system.

Set the clock correctly.

If a recording is in progress, stop the recording.

Power has been interrupted or the power cord

has been disconnected. Reset the clock/timer.

Under no circumstances should you try to repair the system yourself, as this will

invalidate the warranty. Do not open the system as there is a risk of electric shock.
