GENERAL

-How to use this document

Put the QUICK REPAIR layouts behind this manual. Now you are able to follow these specifications with graphical layouts and it is easier for you to find the components and measuring points.

-Component characteristics:

Some components contain important data.

Several described steps are only practicable if you are able to reflash/ realign the phone and/or rewrite IMEI/SIMlock in certain cases. Please pay attention to separate notes.

-Underfills, broken balls, µBGA

It is not possible to change underfilled components. The trial will damage PCB surely. All replaceable µBGA-components must be renewed after removing. Check soldering points, remove oxidated solderings (broken balls) carefully by enclosing few new solder before placing new components. µBGA must be soldered only with NMP approved µBGA-rework machines (e.g. Zevac/OK International). Use only recommended Fluxtype and an appropriate amount of it. Clean very careful the PCB after every rework and take great pains over the keyboard area. Don´t make any loose wiring connections anywhere. If it is necessary to change any item located under the metal shields, remove the shield first don´t cut partially or bend it.

-Realign after repair

Characteristics of replacement parts are different. To prevent additional faults after repair (eg. low standby time, loosing network etc…) it is necessary to retune phone values after repair.

Charging problems

Check soldering of R103 or if bend – in this case change N101. If R103 was bent – check the C-Cover version and cut the arrow of time dial in Cover or change C-Cover if necessary

(Service Bulletin 024).

Not charging (only with ACP-7 charger) if battery is totally discharged – in this case R132 must be changed to 150k / 1% tolerance and R131 must be changed to 82k / 1% tolerance resistors

(Service Bulletin 042).

Poor or no service problems

13MHz Oscillator (G701) must be changed from version „A“ (NGK3092A) to new version „B“ (NGK3092B) – this VCTCXO was only used within below IMEI range and type label, marked as MADE IN FINLAND

First NSE-8 IMEI 448896/10/274359/9 Last NSE-8 IMEI 448896/10/422812/8

First NSE-9 IMEI 448898/10/098643/6 Last NSE-9 IMEI 448898/10/149081/8 (Service Bulletin 018)

Clock- and ringingtone problems

In some cases the ringing tone and/or the clock goes too slow or too fast – in these cases C148 must be changed to 47p / J 50V and C153 to 18p / J 50V and check sine- / squarewavesignals of B100 and change B100 if necessary (Service Bulletin 017).

The first (oldest version with soldering problem)

NSE-8/9 Repair-Hints Service & Analysis Center Europe Version 4.2 –APPROVEDSACE CC Training Group Modified 2000-11-02

Phone doesn´t switch on

Check if track (R132 to L102) located at C110, is printed as upper layer and if this line is 0 Ohm - also place an isolation label on this track (see pictures) to protect this for short cuts to D-Cover. This is necessary in IMEI Number range below 448896/20/485419/5 and 448896/10/205064/9 (Service Bulletin 011).

Check soldering of L102 – In some cases the soldering of the coil can be broken on both sides – change if necessary – Note the different (approved) versions of L102.

The new versions for better reliability below.

. .

Keypad problems

High key press force (eg. Navikey,2,5,8,0) These problems occure due to process change at PCB vendor.

IMEI range: First 448903/10/729000/0

Last 449142/10/432508/8 The PCB´s can be identified by an double arrow symbol on the keypad of the PCB. In this case a new modified keydome sheet is available to solve this problem.

NEW PCB / vendor changes (GD_7) and other component changes

Z 700 / 71 MHz SAW Filter – new ceramic package

If it is necessary to change this Filter, please note: The old (CSSP) and the new (SAW) type are not compatible and cannot be changed against each other

N500 / N501 PHILIPS POWER AMPLIFIER

These are only used with PCB version GD_7xx and not compatible with the Hitachi Amplifiers (different prints). In case of replacement of any Power Amp type it is necessary to tune the sidebands (CH1 and 124 for GSM 900 and CH512 and 885 for GSM 1800) in addition to the Mid Channels (CH 60 and 700) – for tuning instructions also see SERVICE BULLETIN 020.

Different CCONT / N100 versions have been implemented 1st change is CCONT version 2H to version 2I – This new version can replace the old version, but not vice versa! 2nd change is CCONT version 2I to version 2M – New version can replace the old version, but not vice versa!

(Service Bulletin 030 & 40)

New COBBA / N200 version has been implemented

New version COBBA 4.1 can replace the old version COBBA 3.1, but not vice versa! (Service Bulletin 035)

COBBA / N200 underfilling

To prevent that symptoms of dropping calls or loosing service occure - resulting from broken solderings under µBGA – underfilling of COBBA is the solution for those cases, it has been used since IMEI 449143/10/716000/x

NOTE:IT IS NOT POSSIBLE TO REWORK OR REPLACE AN UNDERFILLED COBBA µBGA COMPONENT ! (Service Bulletin 037)
