How to use this document
Put the QUICK REPAIR & COMPONENT FINDER 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 data 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 the PCB surely.
All replaceable µBGA-components must be renewed after removing.
Check soldering points, remove oxidated solderings (broken balls) very careful.
µBGA´s must be soldered only with NMP approved µBGA-rework machines (e.g. Zevac/OK International).
Soldering CSP´s with Hot Air Fan is strictly forbidden!
– refer to General Service Bulletin 106.
Use only recommended fluxtype and always an appropriate amount of it.
PCB handling
Use appropriate cleaning materials only, do not use scratching or rubbing tools. Clean PCB carefully after
every rework and take great pains over the keyboard area. Do not make any loose wiring connections
anywhere.
If it is necessary to change any item located under the metal shields, first remove the shield, do not cut
partially or bend it.
Realign after repair
Characteristics of replacement parts are different.
To prevent additional faults after repair (e.g. low standby time, loosing network etc.) it is necessary
to retune phone values after repair.

CHARGING PROBLEMS
Check if R103 is broken – if resistor was broken or missing: Change N101, too.
Check C-Cover version, cut the arrow of the time dial in cover or change C-Cover if necessary.
(Service Bulletin 024).
NOT CHARGING (with ACP-7 charger only)
If battery is totally discharged – R132 must be changed to 150k / 1% tolerance and R131 must be changed to
82k / 1% tolerance resistor.
For detailed information see Service Bulletin 042.
POOR OR NO SERVICE
13MHz oscillator (G701) must be changed from version “A“ (NGK3092A) to new version “B“ (NGK3092B).
This version “A” VCTCXO is a component used for phones labeled “Made in Finland”, but only within the
IMEI range below mentioned.
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)
TIME & RINGTONE PROBLEMS
In some cases the ringtone and/or the clock work too slow or too fast – in these cases C148 must be changed to 47p, J 50V and
C153 to 18p, J 50V and check 32.768kHz sine- & squarewave signals of B100.
Change oscillator if necessary (Service Bulletin 017).

PHONE DOES NOT 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 it 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).
L102 SOLDERING PROBLEMS
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 first (oldest version with soldering problem)
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 a double arrow symbol on the keypad of the PCB. In this case a new modified keydome sheet is
available to solve this problem.
(Service Bulletin 028 & 032)
PCN PA BUFFER CHANGE
The PCN PA buffer amplifier (N502) is changed from NEC (µpc2771) to RFMD (RF2367) version –
changes apply to HW versions 5.xx. Also the attenuator between the buffer and the PA (R513, R514, R515) is changed from 2dB
to 7dB to compensate the higher saturated power from the RFMD buffer (relative to the NEC buffer

NEW PCB (GD_7), COMPONENT & VENDOR CHANGES
Z700 71MHz FILTER – NEW CERAMIC PACKAGE
If it is necessary to change this filter, please note: The old and the latest type are not compatible and cannot be changed one for
the other!
Old
New
N500 / N501 PHILIPS POWERAMPLIFIER
These are used with GD_7xx PCB only and are not compatible with Hitachi amplifiers (different prints). In case of replacement of
any poweramplifier type, it is necessary to tune the sidebands (CH1 and CH124 for GSM900 and CH512 and CH885 for GSM1800)
in addition to the mid channels (CH60 and CH700) – for tuning instructions see Service Bulletin 020.
DIFFERENT CCONT N100 VERSIONS IMPLEMENTED
1st change is CCONT version 2H to version 2I – This new version can replace the old version, but not vice versa!
nd
2
change is CCONT version 2I to version 2M – New version can replace the old version, but not vice versa!
For detailed information see Service Bulletin 030 & 040
NEW COBBA N200 VERSION IMPLEMENTED
New version COBBA 4.1 can replace the old version COBBA 3.1, but not vice versa!
For detailed information see Service Bulletin 035
COBBA N200 UNDERFILLED
To prevent that symptoms of dropping calls or loosing service appear - 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 µBGA COMPONENT!
For detailed information see Service Bulletin 037
New GSM TX Filter (Z601)
The ceramic version of Z601 is changed to a new version – changes apply to HW versions 5.xx / 55.xx.
These versions can be changed against one for the other.

PHONE DOES NOT SWITCH ON
At first always check mechanical appearance of battery connectors X101/X102 if bent or dirty etc. –
defect connectors could cause additional faults like “not charging” or the phone switches off intermittently.
Does not switch on with battery (nor with service battery)
Check if phone works properly in service jig.
Check if BTEMP AD value is in range of 300.
Check battery connectors X101 / X102 for broken solderings or bent spring contacts (see pictures below).
Check if phone works also after connecting LCD module in jig (short circuit in VBB line from LCD possible).
X504 related fault
Check if connector X504 has its correct position – especially after rework in its area.
If it is misplaced or bent, it could cause possible short circuits to D - Cover with throughholes.
POWER switch S416 faulty
Check mechanical condition of S416.
Check if PWRON at R413 drops to 0V during pressing power switch.
Change powerswitch S416 or continue with CCONT chapter on page#17.
L102 broken/poor soldered
Check soldering of L102.
Check resistance of L102 = 0Ω.
Resolder coil or change if necessary.
See the different versions of coil in HW changes chapter on page#9.
VB line faulty
Check battery voltage VB 2.7VDC at L102.
Check VB 2.8VDC at R132.
Check connection (0Ω) between R132/L102.
See HW changes chapter on page#9 for additional PCB protection.

DC/DC Converter V105 faulty
Check the difference between V101 cathode 3.2VDC / anode 2.6VDC.
Check at V105 – pin 4, 5, 12, and 13: switching frequency 600kHz.
Check 1.2VDC at V105, pin 15.
Check at V105, pin3: 0V. If not, check the respective voltage dividers R131, R132, R134, R143, R144.
If all ok – change V105.
FLASH D301 / SRAM D302 related faults
Check if the current consumption is approximately 20mA.
Try to flash the phone – if this does not work go to chapter “FLASH update not possible” on page#30.
Check also near the service contacts on the PCB - If any component is missing (like on picture below) – flashing will not work!
Torn off components are the result of sliding the phone on the service battery – the contacts can be damaged, too.
NOTE: Always handle the phone in combination with the service battery with care to prevent those failures!
