1Introduction
This manual is intended to help you carry out S6 power PCN repairs on level 2.5, meaning
limited component repairs. Failure highlights are documented and should be repaired in the
local workshops.
The S8 PCN uses the same MMI and RF/Control module as the S6 power PCN but has a
different casing.
It must be noted that all repairs have to be carried out in an environment set up according to
the ESD (Electrostatic Discharge Sensitive Devices) regulations defined in international
standards.
If you have any questions regarding the repair procedures or spare parts do not hesitate to
contact our technical support team in Kamp-Lintfort, Germany:

2.2.1Fault Symptoms for customers:
Network Search
Handset not logging into network
2.2.2Fault Symptom on GSM-Tester:
Frequency error in synchronized mode >90 Hz
No location update possible
The TCXO (Temperature Compenseated Crystal Oscillator) is responsible for generating
the
13 MHz reference frequency of the handset.
If it is defective, the handset cannot synchronize to the base station anymore.

2.4.1Description of procedure:
2.4.1.1Diagnosis
Check the output frequency of the TCXO using the level-2 testing
program for S6 Power PCN.
Set the „Simulator“ option in the S611.INI file to 0 and restart
the program. Start the test, when the program says „Check power and
phase of external antenna with your GSM-Tester“, switch the CMD to
„LOCAL“ mode and enter the „MODULE TEST“.
On the CMD display you can see the frequency error of the handset.
(Make sure that the CMD is on channel 124, power level 5!)
If the frequency error is higher than 2kHz, the TCXO has to be
replaced.
2.4.1.2Repair by component change
Use hot air blower to remove defective TCXO.
Avoid excessive heat!
Watch surrounding components!
Resolder new TCXO afterwards.
2.4.1.3Repair by SW-Booting
Not possible!
2.4.1.4Test
Retest handset after repair as described above.
The frequency error must now be < 2kHz.

3.4.1Description of procedure:
3.4.1.1Diagnosis
Check the status of the fuse by measuring its resistance with
a multimeter. The fuse is defective if the resitance higher than 10
ohms
3.4.1.2Repair by component change
Use soldering iron to remove defective fuse.
Avoid excessive heat!
Watch surrounding components!
Resolder new fuse afterwards.
3.4.1.3Repair by SW-Booting
Not possible!
3.4.1.4Test
Retest handset after repair as described above.
The resistance must now be close to zero.
