Flash programming does not work
The flash programming can only be done via the pads on the PWB (J100). In case of Flash failure in FLALI station, problem is most likely related to SMD problems. Possible failures could be short-circuit of balls under µBGAs (UEM, UPP, FLASH). Missing or misaligned components. In flash programming error cases the flash prommer can give some information about a fault. The fault information messages could be: - Phone does not set FBUS_TX line low Because of the use of uBGA components it is not possible to verify if there is a short circuit in control- and address lines of MCU (UPP) and memory (flash).

Power does not stay on or phone is jammed
If this kind of failure is presenting itself immediately after FLALI, it is most likely caused by ASICs missing contact with PWB. If for some reason the MCU does not service the watchdog register within the UEM, the operations watchdog will run out after approximately 32 seconds. Unfortunately, the service routine cannot be measured.

The phone does not register to the network, or the phone cannot make a call
If the phone does not register to the network, the fault can be in either BB or RF. Only few signals can be tested since several signals are 'buried' in one or more of the inner layers of the PWB. First of all check that SIM LOCK is not causing the error by using a Test-SIM card and connect the phone to a tester.

RF Troubleshooting
Two types of measurements are used in the following. It will be specified if the measurement type is "RF" or "LF". · RF measurements should be done with a Spectrum Analyser and a high-frequency 500 ohm passive probe, for example HP54006A. (Note that when measuring with the 500 ohm probe the signal will be around 20 dB attenuated. The values in the following will have these 20 dB subtracted and represent the real value seen on the spectrum analyser).
Note that the testjig have some losses which must be taken into consideration when calibrating the test system. · LF (Low frequency) and DC measurements should be done with a 10:1 probe and an oscilloscope. The probe used in the following is 10MOhm/8pF passive probe. If using another probe then bear in mind that the voltages displayed may be slightly different.
Always make sure the measurement set-up is calibrated when measuring RF parameters on the antenna pad. Remember to include the loss in the module repair jig when realigning the phone. Most RF semiconductors are static discharge sensitive. So ESD protection must be taken during repair (ground straps and ESD soldering irons). Mjoelner is moisture sensitive so parts must be pre-baked prior to soldering. Apart from key-components described in this document there are a lot of discrete components (resistors, inductors and capacitors) for which troubleshooting is done by checking if soldering of the component is done properly and checking if the component is missing from PWB. Capacitors can be checked for short-circuiting and resistors for value by means of an ohmmeter, but be aware in-circuit measurements should be evaluated carefully. In the following both the name EGSM and GSM900 will be used for the lower band and both PCN and GSM1800 will be used for the upper band. General description of the RF circuits In the following general descriptions different colours are used in the block diagram. The GSM 900 signal route is shown in red, the GSM1800 route in green and the common signal lines are shown in blue. Signal lines which is common for both Receiver signal path The signal from the antenna pad is routed to the RX/TX switch ( Z700). If no control voltage is present at VANT2 and VANT1 the switch works as a diplexer and the GSM900 signal is passed through the RX/TX switch to GSM-RX and the GSM1800 signal is passed to DCS-RX.

Mjoelner N600
From the RX/TX switch the GSM900 signal is routed to the SAW filter (Z602). The purpose of the SAW filter is to provide out-of band blocking immunity and to provide the LNA in Mjoelner (N600) with a balanced signal. The front end of Mjoelner is divided into a LNA and Pre-Gain amplifier before the mixers. The output from the mixer is feed to Baseband part of Mjoelner where the signals amplified in the BBAMP and low pass filtered in LPF1 before the DC compensation circuits in DCN1. The DCN1 output is followed by a controlled attenuator and a second lowpass filter LPF2. The output from LPF2 is DC centered in DCN2 before being fed to the BB for demodulation. The GSM1800 signal chain is similar to GSM900, the SAW filter numbered Z601. Transmitter signal path The I/Q signal from the BB is routed to the modulators for both 900 and 1800 MHz. The output of the modulators is either terminated in a SAW filter ( Z603 ) for GSM 900 or a balun for GSM1800. Both signals are amplified in buffers whereby a limiting effect takes place to suppress some of the AM contents of the signal. The amplitude limited signal is then amplified in the PA (N700) where the gain control takes place. In order to control the TX level a sample of the signal is taken in a directional coupler ( L709 for GSM900 and L704 for GSM1800) and used in the power loop amplifier in Mjoelner to establish the right output power. The TX signal from the couplers is fed to the RX/TX switch, used to select which signal to route to the antenna.

PLL The PLL supplies Local Oscillator (LO) signals for the RX and TX-mixers. In order to be able to generate LO-frequencies for the required EGSM and PCN channels, a regular synthesiser-circuit is used. All blocks for the PLL except for the VCO, reference X-tal and loopfilter is located in the Mjoelner IC. The reference frequency is generated by a 26MHz Voltage Controlled X-tal Oscillator (VCXO) which is located in the Mjoelner IC. Only the X-tal is external. 26MHz is supplied to BB where a divide-by-2 circuit (located in the UPP IC) generates the BB-clock at 13MHz. The reference frequency is supplied to the reference divider (RDIV) where the frequency is divided by 65. The output of RDIV (400kHz) is used as reference clock for the Phase Detector (). The PLL is a feedback control system controlling the phase and frequency of the LO-signal. Building blocks for the PLL are: Phase detector, Charge Pump, Voltage Controlled Oscillator (VCO), N-Divider and loopfilter. As mentioned earlier only the VCO and loopfilter is external to the Mjoelner IC. The VCO (G600) is the component that actually generates the LO-frequency. Based on the control voltage input the VCO generates a single-ended RF output. The signal is then differentiated through a balun. This signal is fed to the Prescaler and N-divider in Mjoelner, these 2 block will together divide the frequency by a ratio based on the selected channel. The divider output is supplied to the phase detector which compares the frequency and phase to the 400kHz reference clock. Based on this comparison the phase

detector controls the charge pump to either charge or discharge the capacitors in the loopfilter. By charging/discharging the loopfilter the control voltage to the VCO changes and the LO-frequency will change. Therefore the PLL will make the LO-frequency stay locked to the 26MHz VCXO frequency. The loopfilter consists of the following components: C639-C641 and R618-R619. The PLL is operating at twice the channel center frequency when transmitting or receiving in the PCN band. For the EGSM band the PLL is operating at 4-times the channel frequency. Therefore divide-by-2 and divide-by-4 circuits are inserted between the PLL output and LO-inputs to the PCN and EGSM mixers.

Synthesizer
There is only one PLL synthesizer generating Local Oscillator frequencies for both RX and TX in both bands ( PCN and EGSM). The VCO frequency is divided by 2 for PCN operation or by 4 for EGSM operation inside the Mjoelner IC. General instructions for Synthesizer troubleshooting Start the Phoenix-Service-Software and Select: Product: NHM-8NX Select: Maintenance, Testing and then RF Controls. Band Active Unit Operation Mode RX/TX Channel GSM1800 RX Continuous 700
It is not possible to measure the output of the VCO (G600) directly as this component is placed underneath a shielding can without detachable lid. However with spectrum analyzer and 500 ohm passive probe it is possible to get an indication if the VCO outputs the correct frequency. To do this probe R656 the frequency should be 3685.6MHz and the power should be around 50 dBm. 26 MHz Reference Oscillator ( VCXO ) The 26 MHz oscillator is located in the Mjoelner IC (N600). The coarse frequency for this oscillator is set by an external crystal (B600). The reference oscillator is used as a reference frequency for the PLL synthesizer and as the system clock for BaseBand. The

26MHz signal is divided by 2 to achieve 13MHz inside the UPP IC (D400). The 26 MHz signal from the VCXO can be measured by probing R425 (must be measured on the UPP side of R425 i.e. the end not connected to C425). The level at this point is approx. 700mVpp. Frequency of this oscillator is adjusted by changing the AFC-register inside the Mjoelner IC. This is done via the Mjoelner serial interface. Example Signal Measured at VCXO output (R425)

CCS Technical Documentation VCO
RH-9 Troubleshooting Instructions
The VCO is generating frequencies in the range of 3420.2MHz 3839.2 MHz when the PLL is running. The output frequency from the VCO is led to the Local oscillator input of the Mjoelner IC (N600), where the frequency is divided by 2 or 4 so that they can generate all channels in EGSM and PCN respectively. Frequency of the VCO is controlled by a DC-voltage ( Vctrl ) coming from the loopfilter. The loopfilter consists of the components R618, R619 and C639-C641. Range of the Vctrl when the PLL is running (locked) is 0.7V 3.8V. Even if the PLL is not in locked state (Vctrl out of range) there is some frequency at the output of the VCO (G600) which is between 3 and 4 GHz. This is of course only true if the VCO is working and if the VCO power supply is present (2.7V). Fault finding chart for PLL Synthesizer

If the phone stops working a short time after the power is turned ON, a possible reason forthis might be that the 26MHz system clock signal is not getting to the UPP clockinput in BaseBand. In this case check the following: 1 Turn on the phone and check 2 VCXO Power supply (C620) = 2.7V 3 VCXO output (R425 end not connected to C425) is 26MHz and approx. 700mVpp If this is not the case check the reference crystal (B600) and Mjolner (N600) as well as R425, R426, C425, C426.

Alignment
NHM-8NX manual align with Phoenix In Phoenix select connection Fbus and Product Gemini. If you power up the board before selecting Fbus, it works without any error messages. Use Jig or other device for RF and bus connection. Attenuation in the probe alone is 0.5dB for 900 and 1dB for 1800. Use CMD55 or other suitable device. Default channels are 37 for GSM900 and 700 for GSM1800. The alignments and calibrations must be performed in the order shown to give reliable results. The way to save data to the phone and to load data from the phone is made different in the various tunings. Always look what is shown in the windows regarding these issues and act accordingly. To vary a selected parameter you can use + and key or in some cases directly type the new value. + and steps the value for every press. Repeat function seems not to work. In I/Q you can use the side arrows.
