If current is still not ok, lift C702/703/704 and C754/755 one by one.
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 11 (35) Version 2.0 Approved CONTACT SERVICE This fault means that the phone software is able to run and thus the watchdog of CCONT (N100) can be served. Selftest functions run when power is switched on and software is executed from ComboMemory. If any selftest fails, a “Contact Service“ text is shown on LCD. Possible failures: MCU ROM Checksum failed Try to flash the phone.
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 12 (35) Version 2.0 Approved PHONE INTERMITTENT SWITCHES OFF/ DOESN’T SWITCH ON Check mechanical appearance of connector X101. Check that pads of X101 on PCB are clean. Check amplitude of 32.768kHz at J228, 3.2Vpp squarewave, probably broken solderings under CCONT N100. Remove CCONT if not underfilled and replace it with µBGA rework machine.

Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 14 (35) Version 2.0 Approved X110 DC/HS connector, X101 battery connector Check mechanical appearance of connectors, make sure that pads for connectors on PCB are clean. F101 faulty Check resistance of F101 (0 Ohm). Vcharge line shorted to GND. Check resistance of Vcharge line at F101 to GND (50 kOhm). If resistance is not ok, remove L104 and check again.
CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 Service & Analysis Center Europe SACE CC Training Group 15 (35) Version 2.0 Approved SIMCARD FAULTS "Insert SIMcard" Check X302 if bend or soiled, check contact pads on PCB nOK Change X302, clean PCB if necessary OK Check Signals at V104: Pin1 SIMCLK pin3 VSIM pin4 SIMData pin5 SIMRST nOK Check R124/125/128, resistance of SIMlines to GND.
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 16 (35) Version 2.0 Approved VSIM after switching on the phone without SIMcard. CCONT pulses up VSIM four times, at first the amplitude is 3 Volt, the next three times 5 Volt. If the phone is switched on with SIMcard, Vsim stays on level with which SIMcard works, expected that SIMcard is not dirty or damaged.
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 17 (35) Version 2.0 Approved 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. X 302 SIMcard Reader Check if bent or soiled, change if necessary.
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 18 (35) Version 2.0 Approved NO SERVICE First of all: Calibrate RX/TX values to define the fault. No or too low TX power GSM 900 Use WinTesla to set phone into following mode: “Initialise/ Local mode/Testing/ RF Controls/ active unit TX, Ch.60”. Check 26MHz reference oscillator at C830, 700mVpp, frequency deviation < 100Hz. Check TXI/Q signals at R541/546, refer to signals shown on next pages.
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 19 (35) Version 2.0 Approved 26MHz reference oscillator faulty Check Vcc 2.7V at C831 and Vcon (varies between 0.3V and 2.3V) at C832. If frequency deviation is higher than +/- 100 Hz, it is necessary to change the oscillator. Check appearance and pads of R832.(AFC-line). G800 SHF oscillator faulty Check frequency of oscillator if possible – refer to frequencies worksheet on page 27.

Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 21 (35) Version 2.0 Approved N702 power amplifier faulty Check TX power signal at pin 8 of N702. Check TXVGSM at pin 1 of N702 (2.8Vpp squarewave/ 217Hz). Check Vapc at pin 7 of N702 (1- 1.6Vpp depending on powerlevel). Check Vbatt at pin 3 and 6 of N702. If all values are ok but still there´s no or too low TX power measurable at L553 pin 1, change N702.
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 22 (35) Version 2.0 Approved No or too low TX power GSM 1800: Use WinTesla to set phone in following mode: Initialise/Product/Band/PCN/Testing/RF Controls/active unit TX Ch.700. To find a fault in GSM 1800 TX mode, you can proceed almost the same way as described for GSM 900: Check 26MHz reference oscillator at C830, 700mVpp, frequency deviation < 100Hz. Check TXI/Q signals at R541/546.
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 23 (35) Version 2.0 Approved If signal is not ok, check VRXrf 2.8V at C557, check also Vchp 4.8V at C560 and frequency of G800 at C788 (RX Ch.60: 3788MHz) or change HAGAR (N505). Check 67,708kHz at C520/521 (burst mode, input level –65dBm). Check 67,708kHz at R510 (burst mode, input level –65dBm).
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 24 (35) Version 2.0 Approved Check 67.708kHz at C530/531 (burst mode, input level –65dBm). Check 67.708kHz at R530 (burst mode, input level –65dBm). If signal is not ok at R530, check Vref 1,35V at C535, also check C530-C533 if broken or broken soldered, change HAGAR (N505) if necessary. COBBA (N250) faulty Check Vbb 2,8V at C201 and VCOBBA 2.8V at C248.
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 25 (35) Version 2.0 Approved No RX - calibration GSM 1800 possible. Use WinTesla to set phone in following mode: Initialise/Product/Band/PCN Testing/RF Controls/ active unit RX Ch.700, burst mode. Set RF- Generator to a high RF- Level output, eg –40dBm.
Service & Analysis Center Europe SACE CC Training Group CONFIDENTIAL NSM-2/3 Repairhints 2000-10-16 26 (35) Version 2.0 Approved Faulty TX - spectrum 1) 3) 2) 4) Pic.1: Normal spectrum Pic.2: Spectrum with broken solderings under CCONT. Spectrum turns to picture 1 if CCONT is pushed carefully with a nonmetallic item. Pic.3: Spectrum of faulty COBBA (RSSI-Alignment not possible, TXI/Q faulty). Pic.4: Spectrum of faulty oscillator G800, both COBBA or HAGAR can be the reason.
