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).

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)

C111, C112 C113, C115 faulty
-Check the current consumption in different operation modes (refer to the table below).
-Check if the high current consumption results from the VB, Vout or output voltages of CCONT.
Disconnect coil by coil L105 (→N702) L505, L506 (→PA's) and check consumption again.
-Check and desolder C111,C112, C113 and C115.
-Calibrate Battery values if charging stops too early or battery is too hot after charging
(also see chapter "Not charging).

N200 COBBA faulty /solder balls broken
-Check VBB 2,8V DC at C117 near to CCONT.
-Check VCOBBA 2,8V DC C248 near to COBBA.
-Check COBBACKL 13MHz 3,2Vpp at J 201 (see diagram below).
-Check COBBA reset impulse during initialisation routine at J343 (see diagram below) .
-Change COBBA and write the IMEI and SIM-LOCK DATA back to the phone.
If error persists, MAD or PCB should be the reason.
SWAP the unit because MAD is not changeable.
Note! Rewrite SIMLOCK and IMEI entries with use of the Nokia security Password and make a SW-update or send
these phones to SACE, if this procedure is not permitted to you

D303 Eeprom faulty
-Check with WinTesla if IMEI or product data are corrupted.
-Check 2.8V DC at pin 8 of Eeprom.
Don't use the "Full factory set" with WinTesla, otherwise the original IMEI will be changed to
"65656565…"
Change the Eeprom if it is permitted to you and write back all ID data (IMEI, product code…).
If you are not autorized to change Eeprom and the IMEI is missing, write a note with a short
comment, and send it together with the phone to the SACE.
Note! Rewrite SIMLOCK and IMEI entries with use of the Nokia security Password and make a SW-update or send
these phones to SACE.

VSIM after switching on the phone without SIMcard. Ccont pulses up VSIM for four times, the first
time the amplitude is 3 Volt, the next three times it is 5 Volt.
If the phone is switched on with SIMcard VSIM stays on the level with which the SIMcard will work,
expected that SIMcard is not dirty or damaged.
Note that SIMclock and SIMdata are only present when SIMcard is active, for example when phone
registers to network.
SIMReset is low-active, that means that the SIMcard will be reseted when SIMReset is 0 Volt.
This is the case after switching on the phone ( diagram above ). While VSIM is already high,
SIMReset keeps low for a few milliseconds – in this time the card will be reseted.
