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.

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 (|ipc2771) 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!

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! 2nd 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 |BGA - 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 ^BGA 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.
