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)

If the flash 0 is faulty, it is
possible that no blinking

The flash 1 (D352) is faulty. This can be seen at the second flash ID
(0000-0000)
in the first case.
In the most cases D351 is faulty, but also the whole Flash (D351- D354) or D300 MADLINDA could be faulty.
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
D352
D353
D354
Vcore at C360/C361
Vcore at C362/C363
Vcore at C366/C370
---
VBB at C353/C354
VBB at C355/C356
VBB at C364/C365
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)
