3 1 Introduction 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: Tel.: Fax: dominik.schnoor@klf.siemens.de 2 TCXO V1.1 Page 3 of 22 PN MP ST

4 2.1 Affected Units Type: S6 Power PCN Affected IMEIs / Date Codes: All / All Affected SW-Versions: All Fault Code for LSO reporting: 3TCX 2.2 Fault Description Fault Symptoms for customers: Network Search Handset not logging into network Fault 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. 2.3 Priority:... Mandatory... Repair... Optional... Not Yet Defined 2.4 Repair Documentation V1.1 Page 4 of 22 PN MP ST

5 2.4.1 Description of procedure: Diagnosis Repair by component change 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. Use hot air blower to remove defective TCXO. Avoid excessive heat! Watch surrounding components! Resolder new TCXO afterwards Repair by SW-Booting Not possible! Test Retest handset after repair as described above. The frequency error must now be < 2kHz List of needed material Components V1.1 Page 5 of 22 PN MP ST

9 Diagnosis Repair by component change Check the status of the fuse by measuring its resistance with a multimeter. The fuse is defective if the resitance higher than 10 ohms Use soldering iron to remove defective fuse. Avoid excessive heat! Watch surrounding components! Resolder new fuse afterwards Repair by SW-Booting Not possible! Test Retest handset after repair as described above. The resistance must now be close to zero List of needed material Components Fuse V1.1 Page 9 of 22 PN MP ST

Output power problems on the external and internal antenna. No location update possible.... Mandatory... Repair... Optional... Not Yet Defined 5.4 Repair Documentation Description of procedure: Diagnosis Repair by component change Visually check the bottom connector. Watch for dry joints. Use hot air blower to remove defective connector. Avoid excessive heat! Watch surrounding components! Resolder new connector afterwards. Make sure that you use just very little flux, otherwise the connector contacts can become dirty Repair by SW-Booting V1.1 Page 16 of 22 PN MP ST
