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 does not work
3. Power does not stay on or the phone is jammed
4. Display information: Contact Service
5. Phone does not register to the network or phone does not 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
There are two possibilities to route programming voltage VPP.
– If regulator N200 is used the programming voltage comes from the reg-
ulator (VPPSW) via UI–connector to flash memory D210.
– Other way is to route Vpp from CCONT pin36 to UI–connector and
again to flash memory.
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 J206 and J207.
2. Switch power on
3. If the voltage level in testpoint J205 is 2.8 V (”1”), the interface is OK. If
there is a short circuit, the voltage level in testpoint J205 stays low and
32kHz square wave signal can be seen in the lines which are already
tested.
This test can only be used to find 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 watchdog 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 failed, contact service information will be shown on dis-
play.
The phone doesn’t register to the network or phone
doesn’t make a call
f 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; N300). 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).

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) rise up 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.
