GENERAL
-How to use this document
Put the QUICK REPAIR layouts behind this manual.
Now you are able to follow these specifications with graphical layouts and it is easier for you to find the components and measuring points.
-Component characteristics:
Some components contain important data.
Several described steps are only practicable if you are able to reflash/ realign the phone and/or rewrite IMEI/SIMlock in certain cases. Please pay attention to separate notes.
-Underfills, broken balls, µBGA
It is not possible to change underfilled components. The trial will damage PCB surely. All replaceable µBGA-components must be renewed after removing. Reflow is not allowed.
Check soldering points, remove oxidated solderings (broken balls) carefully by enclosing few new solder before placing new components.
µBGA must be soldered only with NMP approved µBGA-rework machines (e.g. Zevac/OK International). Use only recommended Fluxtype and an appropriate amount of it.
-PCB handling & cleaning
Only use appropriate cleaning materials, don`t use scratching or rubbing tools. Clean PCB carefully after every rework and take great pains over the keyboard area. Don´t make any loose wiring connections anywhere.
If it is necessary to clean the PCB, please pay attention to the following: Because of organic surface protection (OSP), cleaning must only be done with a lint-free cloth which may be moisten with DI-water. IPA or other solvent like ethanol should only be used to clean gold pads for spring contacts without affecting the surrounding copper layers.
If it is necessary to change any item located under the metal shields, remove the shield first, don´t cut partially or bend it.
-Realign after repair
Characteristics of replacement parts are different.
To prevent additional faults after repair (eg. low standby time, loosing network etc.) it is necessary to retune phone values after repair.

|
In case of HW-ID 0600, 0601,0602, 0603, 0604, 0607, 0608, 0612 and 0614 change following parts:
R559 from 2.2kΩ to 1kΩ |
(1430754) |
|
C559 from 100pF to 47pF |
(2320552) |
|
C560 from 1nF |
to 47pF |
(2320552) |
C303 from 1nF |
to 47pF |
(2320552) |
Since HW-ID 0615 these changes are implemented in production.
Software update to PhoneSW 4.06 or higher makes above mentioned HW update unnecessary (SB16)
Difficulties when removing B-Cover ( SB 13 )
If customers critisize bad removal of B-Cover cut away the guiding pin of the D-Cover ( see picture below ) After this procedure it is necessary to assemble the phone with a torque screwdriver prepared for 30Ncm!

X203 Battery connector
Check if bent or soiled.
Check that pads of connector on PCB are clean.
S419 Power on/off switch faulty
Check that voltage at R402 is 3.6V when powerswitch is not pressed. If voltage is not ok, check R402 and R224, change N201 if necessary.
If voltage at R402 is ok, it must decrease to 0V if S419 is pressed, else change S419. Disable watchdog by connecting R224 to GND if phone switches off after 2 or 3 seconds.
B200 Sleep Clock Oscillator faulty
Check 32.768kHz, 3Vpp squarewave at pad of C220 located towards B200.
If oscillator does not work, check voltage at the two pads of B200 which are located towards N201, normally 1.6V DC. If not ok, check periphery of B200 or change CCONT N201. If frequency is not ok, check parts around B200 (R211, R212, R214, C229/230).
G502 Reference oscillator faulty
Check Vcc 2.7V DC at G502 pin 2 and Vcont (varies between 0.03V and 2.3V, typically 1.3VDC) at C552. Check 26MHz Clk-frequency at pin 3 of G502, 1Vpp
Check 13MHz Clk-frequency at C559, 300mVpp
If not ok, check voltages for HAGAR N500. (Detailed information in chapter “No Service”). Check 13MHz Clk-frequency at C303, 500mVpp at pad located towards V103.
If not ok, check values around V502
N201 CCONT faulty
Check Vb 3.6V DC at C227/228.
Check 32.768kHz, 3Vpp squarewave at pad of C220 located towards B200. Check that PWRONX decreases from 3.6V DC to 0V at R402 if powerswitch is pressed.
If these conditions are fulfilled output voltage lines should rise to their intended values and PURX is released after some milliseconds by CCONT.
If CCONT does not work, check output voltage lines for shorts to ground ( check current consumption! ), if ok, change CCONT with µBGA soldering machine and run energy management calibration.
D300 MAD faulty
Check 32.768kHz squarewave at C220.
Check 13MHz Clk-frequency at C303.
Check Vbb 2.8V DC at C209/211 and Vcore 1.7V DC at L200.
Check SLEEPX 2.8V DC at J308.
Check PURX 2.8V DC at R308.
Try to flash the phone.
MAD is probably faulty, swap the phone because MAD is not changeable.

PHONE INTERMITTENT SWITCHES OFF/DOESN`T SWITCH ON
Check first of all phone´s software version.
If version is < 4.06, make SW update and check if fault persists.
If phone switches off intermittent although phone SW is 4.06 or higher and battery is fully charged, check phone´s HW-ID.
In case of HW-ID 0600, 0601,0602, 0603, 0604, 0607, 0608, 0612 and 0614 it is necessary to change the following parts:
R559 from 2.2kΩ to 1kΩ |
(1430754) |
|
C559 from 100pF to 47pF |
(2320552) |
|
C560 from |
1nF to 47pF |
(2320552) |
C303 from |
1nF to 47pF |
(2320552) |
If HW-ID is 0615 or higher, the above mentioned changes are already done.
Other possibilities if SWand/or HW-update do not solve the problem:
Check mechanical appearance of connector X203. Check that pads of X203 on PCB are clean.
Check amplitude of 32.768kHz at C220, 3Vpp squarewave,
probably broken solderings under CCONT N201. Remove CCONT and replace it with µBGA soldering machine, run energy management calibration after changing CCONT.
The same problem may be caused by N500, because the reference oscillator G502 ( 26MHz ) is divided to 13MHz system clock by HAGAR N500.
