General
- How to use this document
Place the schematics behind this manual.
Now you are able to follow these specifictions with graphical layouts and it is easier for you to find the components and
measuring points.
- General handling
All screws must be screwed with a torque of 16Ncm. If a higher torque is used, the cover might be damaged.
If it is necessary to make a backup, be sure that the data are ok, otherwise it is possible that the corrupt files are responsible for
the same faults as before reinstalling the backup.
- µBGA components and broken balls
Special attention to µBGA components:
All µBGA´s with the exception of MADLINDA D300 are replaceable and must be renewed after removing. Reflow by hot air fan is
not allowed.
Check soldering points, remove oxidated solderings (broken balls) carefully by enclosing a few new solders before placing new
components. The only allowed way to change µBGA components is to use µBGA rework maschines, approved from NMP (e.g.
ZEVAC/ OK International). Only use recommended Fluxtype and an appropriate amount of it.
- Component charactaristics
Some components contain important data.
Several described steps are only practicable if you are able to reflash/ realign the Communicator 9210 and/ or rewrite IMEI/
SIMlock in certain cases. Please pay attention to separate notes.
- Realign after repair
Characteristics of replacement parts are different.
To prevent additional faults after repair (RX quality, TX power etc.) it is necessary to retune phone values.

Flash faults
PDA does not start/ or Phone backlight is blinking.
PDA backlight is working but nothing on PDA display.
Note! If the communictator does not boot up after connecting the battery, pay attention to the Phone display. If the
Phone backlight is blinking, refer to the service manual/ Troubleshooting/ Memory Test and/ or Memory troubleshooting,
(See blink code table below) otherwise try to flash the phone first.
- If nothing is on PDA display, interchange the BL8 and UL2 modules with working onces, to find out which is faulty.
- If the flash update failed, pay attention to the Flash ID´s (See picture below)
Blink code table
2* blinks = Flash 0 or 1 or 2 faulty
3* blinks = SDRAM faulty
4* blinks = Serial Flash faulty
The blinks repeating after 2
seconds. It is not easy to see.
If the flash 0 is faulty, it is
possible that no blinking
sequence is shown on the phone
display and the communicator
does not boot up.
To 1) - The flash 1 (D352) is faulty. This can be seen at the second flash ID (0000-0000) in the first case.
To 2) - In the most cases D351 is faulty, but also the whole Flash (D351- D354) or D300 MADLINDA could be faulty.
To 3) - In this case all flash IDs and MADLINDA are OK.
- If one of the IDs is 0000-0000, check Vcore = 1.8 VDC and VBB = 2.8 VDC at following components:
D351 Vcore at C360/C361 VBB at C353/C354
D352 Vcore at C362/C363 VBB at C355/C356
D353 Vcore at C366/C370 VBB at C364/C365
D354 --- VBB at C369
- If Vcore is not ok, check Vcore = 1.8 VDC Pin 4 and Vbatt = 4 VDC at Pin 3 of V105 (VBatt depends on settings of power
supply at the workbench). (Note! VBatt = VB) Also check surrounding components for shorts or disconnections and resolder
or change faulty ones if necessary.
- If VBB is not ok, check VBB = 2.8 VDC at C111. If not ok, check VB = 4VDC at Pin 6 of N102.
- If VB is ok, check N102 and surrounding components for shorts or disconnections and resolder or change the faulty ones if
necessary.
- If all voltages are ok, change the faulty Flash and flash the phone.
- If the fault persists, probably the MADLINDA (D300) is faulty. Up to HW 4.00, the D300 is not changeable because of
underfill. From HW-ID 4.23 with OSP, the MADLINDA is changeable. (See SB-027)

D354 Serial Flash faults
- SW update not successful (Set Phone power on)
- PDA hangs up
- Error messages appears on PDA display
- If, at the end of flash update, the message “Set phone power on” appears on display (Flash IDs must be correct; see picture at
chapter Flash faults), probably the D354 Serial Flash is faulty and has to be changed.
- If the PDA often hangs up or error messages are appearing on PDA display, try to flash the phone.
- If the same faults persist after flashing, the D354 Serial Flash is faulty and has to be changed.
D353 Flash faults
Emulated EEPROM at D353 Flash faulty
- Product Code and HW version not rewriteable
- IMEI 15*0 / Original Serial Number = 656565656565656
- Flashing Error message “Can´t Set factory counter”
- Check which fault has happened using WinTesla menu Testing/ Selftest (e.g. MCU ROM Checksum).
- If one of the EEPROM faults occured, open menu View/ Phone Information and take a look the marked values.(See picture)
Try to flash the communicator with SW 4.13 and promming option Erase Only. Also the memory card has to be updated. If the
MMC is not updated some applications do not working well. (See SB-023)
For a faster MMC-image update it is a good solution to use ext. drive for MMC. (See SB-018)
For Erase Only it is necessary to use the dll version 04.00.00 and the modified RAE3.ini file. (See SB-025)
(Note! Copy the modified RAE3.ini in the WinTesla/RAE-3 directory. If the RAE3.ini file is not in the right directory the erase only
button in the flash menu is not free to choose.)

the flash D353
- After erasing the emulated eeprom, part of the XIP flash D353, the display shows contact service.
- Now flash the phone without marking erase only.
- After flash update set Full Factory and Accessory
(for Accessory see also chapter 4 “Connection with
any kind of accessory not possible”) under menu
software/ Set Factory values (See picture below),
also rewrite product code and HW-ID.
- Rewrite IMEI and SIMlock data if the procedure is permitted to you and tune the phone
- If the erase only procedure not works change the D353 flash.
- After changing the D353 Flash EEPROM, flash the phone. If the SW update was successful, make a full factory and Accessory
set, then rewrite the product code and the HW-ID. After that, rewrite IMEI and SIMlock data.
- If the sw update is not successful, probably D300 MADLINDA is faulty. Up to HW 4.00, the D300 is not changeable because of
underfill. From HW-ID 4.23 with OSP, the MADLINDA is changeable. (See SB-027)
(Note! Everytime when it is necessary to change the D353 EEPROM or erase the EEPROM, a Full Factory set and
Asseccory set must be done!
Note! Rewrite SIMlock and IMEI data by use of NOKIA SECURITY PASSWORD and make a SW-update again, if the
procedure is permitted to you. (See SB–037)

PDA display dark
CCFT Lamp and Piezo unit faulty
- If the PDA starts up (startup logo is seen), but the illumation is off, probably the piezo is broken or the backlight circuit is
faulty.
- Check Piezo_in frequency around 135kHz (Vpp = 10 VAC) at L151 and Feedback frequency around 135kHz (Vpp = 2.7 VAC)
at R158. (See picture below)
Piezo_in Feedback
- If Feedback frequency is around 0Hz or Piezo_in frequency is around 100kHz, change CCFT (See SB-014), because the piezo
is broken (see pictures below)
- If changing the CCFT, do not forget to paste the damper (9480703) on the CCFT Lamp and Piezo unit to prevent noises and
damages. (See picture below)
- If the fault persits, probably the UL2 module can also be faulty. (Refer to Service Manual/ Troubleshooting/ BL8 related PDA

Connection with any kind of accessory not possible
Accessory set
If the communicator does not connect to any kind of accessory it can be possible that the flash D353 has been changed or the
EEPROM has been erased without making an Accessory Set. Open under WinTesla menu Software/ Set Factory values/ and set
Accessory than try to connect the phone again.
Note! Sometimes it is possible that the connection takes a while.
MMC not formatable
If the communicator hangs up while formating the MMC, it is necessary to flash the phone with newes sw 4.13.
Note! When updating the phone sw, it is also necessary to update the MMC with the newes image. (See SB-023)
For a faster MMC-image update it is a good solution to use ext. drive for MMC. (See SB-018)

G800 SHF oscillator faulty
- Check TX I/Q EGSM, Ch: 60 with WinTesla menu Tuning/ TX I/Q. (See picture below)
The G800 SHF Oscillator is working well The Oscillator is not working
- If Picture 2 is appearing on spectrum analyser, check following voltages:
- Check Vsynte (VSYN_2/VCC) = 2.8 VDC at R808. If not ok, lift R808 and measure the voltage on the pad to HAGER`s side. If
Vsynte is ok, check G800 SHF oscillator and surrounding components for shorts or cold soldering and change or resolder the
faulty ones.
- If Vsynte (VSYN_2/VCC) is not ok after lifting R808, check N100 CCONT.
- Check VC = 2.2 VDC at R802.
- Check Vchp = 4.7 VDC at C560. If not ok, check VCP = 4.9 VDC at N600 Pin 6. If not ok either, check N100 CCONT.
- If VCP is ok, check N600 voltage regulator and surrounding components for shorts or disconnections and change the faulty
ones. If the surrounding components are ok, change G800 SHF oscillator.
