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 divided 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

Disassembly & Troubleshooting Instructions
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.
Phone is totally dead

Flash programming doesn’t work
The flash programming can be done via panel connector X001 or via system 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.
YES
Check R118, X300
NO
Check UI module
Check watchdog disable line to
X001

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 information about a fault.

Technical Documentation
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 already tested.
Disassembly & Troubleshooting Instructions
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.
