Trouble Shooting
The following hints should facility finding the cause of the problem when
the circuitry seems to be faulty. This trouble shooting instruction is di-
vided following section.
1. Phone is totally dead
2. Flash programming doesn‘t work
3. Power doesn‘t stay on or the phone is jammed
4. Display information: Contact Service
5. Phone doesn‘t register to the network or phone doesn‘t make a call.
6. Plug in SIM card is out of order ( insert SIM card or card rejected).
7. Audio fault.
8. Charging fault
The first thing to do is carry out a through visual check of the module. En-
sure in particular that:
a) there are not any mechanical damages
b) soldered joints are OK

Phone is totally dead
This means that phone doesn’t take current at all when the power switch
is pressed or when the watchdog disable pin (X001 pin 11) is grounded.
Used battery voltage must be higher than 3.0 V. Otherwise the hardware
of CCONT (N100) prevents totally to switch power on.

Flash programming doesn’t work
The flash programming can be done via panel connector X001 or via sys-
tem connector X100.
In production, the first programming is done via panel connector X001.
After this, the panel connector is cut away, thus other flash programmings
must be done via system connector X100.
The main differences between these are:
a) FLASH programming voltage is produced different way.
b) Signal routings are different.
The fault finding diagrams for flash programming via panel connector are
shown in figures 32 and 33.
The fault finding diagrams for flash programming via system connoctor
are shown in figures 34 and 35.
In flash programming error cases the flash prommer can give some in-
formation about a fault.

The fault information messages could be:
– MCU doesn’t boot
– Serial clock line failure
– Serial data line failure
– External RAM fault
– Algorithm file or alias ID don’t find
– MCU flash Vpp error
In cases that the flash programming doesn’t succeed there is a possibility
to check short circuits between the memories and the MCU (MAD2).
This test is useful to do, when the fault information is: MCU doesn’t boot,
Serial clock line failure or Serial data line failure.
The test procedure is following:
1. Connect the short circuit wire between the test points J229 and J230.
2. Switch power on
3. If the voltage level in testpoint J225 is 2.8 V (”1”), the interface is OK. If
there is a short circuit, the voltage level in testpoint J225 stays low and
32kHz square wave signal can be seen in the lines which are al-
ready tested.
One must be noticed that this test can be found only short circuits, not
open pins.
Also upper data lines (15:8) of flash circuit D210 are not included to this
test.

Power doesn’t stay on, or phone is jammed
If this kind of fault has come after flash programming, there are most
probably open pins in ICs.
The soldered joints of ICs: D200 (MAD2), D210 (FLASH), N100
(CCONT), D221 (SRAM) are useful to check at first.
Normally the power will be switched of by CCONT (N100) after 30 se-
conds, if the watchdog of the CCONT can not be served by software.
The watchdog updating can be seen by oscilloscope at pin 50 (DataselX)
of CCONT.
In normal case there is a short pulse from ”1” –> 0 every 8 seconds.
The power off function of CCONT can be prevented by connecting a short
circuit wire from CCONT pin 29 to ground.

Display Information: Contact Service
This fault means that software is able to run and thus the watchog of
CCONT (N100) can be served.
Selftest functions are run when power is switched on and software is
started to excute from flash.
If any of selftests is failed, contact service information will be shown on
display.
The phone doesn’t register to the network or phone
doesn’t make a call
If the phone doesn’t register to the network or the phone doesn’t make a
call, the reason could be either the baseband or the RF part.
The phone can be set to wanted mode by WinTesla service software and
determinate if the fault is in RF or in baseband part (RF interface mea-
surements).
The control lines for RF part are supplied both the System Asic
(MAD2;D200) and the RFI (Cobba; N250). MAD2 handles digital control
lines ( like synthe, TxP etc.) and Cobba handles analog control lines (like
AFC, TxC etc.).
The DSP software is constructed so that operation states of DSP (MAD2)
can be seen in external flag (DSPXF) output pin (D200 pin 91).
After power up, DSP signals all completed functions by changing the state
of the XF pin (see figures 39 and 40).

SIM card is out of order
The hardware of the SIM interface from MAD2 (D200) to the SIM connec-
tor (X302) can be tested without SIM card.
When the power is switched on and if the BSI line (X101;1) is grounded
by resistor, all the used lines (VSIM, RST, CLK, DATA) rises up to 5 V four
times. Thus ”Insert SIM card” faults can be found without SIM card.
The fault information ”Card rejected” means that ATR message (the first
message is always sent from card to phone) is sent from card to phone
but the message is somehow corrupted, data signal levels are wrong etc.
or factory set values (stored to the EEPROM) are not correct.
