NOT CHARGING FAILURES
If you are using WinTesla NSE-8/9 with DLL 2.41.03 or lower, the error message "current calibration fail"
will appear in every charge tuning calibration test!
See additional information in Service Manual:
Chapter "Service Software Instructions", page# 21 (Energy Management Calibration)
X101/102 and X503 faulty
First of all check the mechanical condition of all connectors and clean connector-pads (X503) on PCB and/or change bent or
damaged connectors if necessary –also see pictures on page # 14.
If any connector is poor soldered – additional faults will be the result!
F100 faulty
Check resistance of fuse F100 (0Ω).
Check resistance of V_CHARGE_IN line to GND – should be around 10KΩ.
If the line is in lower-Ohm range, check the PCB for possible liquid or mechanical damages.
R103 faulty or broken
If the phone does not charge when ACP-9 fast charger is connected:
Check mechanical condition of R103 (some versions of this resistor can be broken through mechanical stress)
If the component is broken or is completely missing – change R103 and additional PSCC N101.
(PSCC defect by using charger with broken or missing R103)
If a broken resistor is the reason for this fault, check also C-Cover and cut away the arrow in time dial (by using e.g. scalpel)
or replace it if necessary – see HW changes page# 8 for additional information.
R125 to R127 connection faulty
Check with WinTesla/local mode/Testing/ADC readings
Check connection between R125 (near CCONT) and R127 (near X101) = 0Ω and check the resistance of R127 = 47kΩ.
If R127 is broken or poor soldered, the battery indication bar on LCD will appear flashing when charger is connected to phone.
C100 broken
Display-message "Not charging"
Check mechanical condition of C100 (near PSCC) – change capacitor if broken (sometimes only hairline crack)
Check C-Cover (bent or damaged) if C100 is broken – change if necessary
Charging problems with ACP – 8/9 charger
(Sometimes charging stops after LCD light turned off)
Check if the problems do appear with these chargers only and if the phone works properly with ACP – 7 charger.
Check R117 (10kΩ) and R142 (10kΩ) in CHARG_CTRL line if these are poor soldered or in MΩ range – change if necessary.
Check V200 in CHARG_CTRL line for shorts to GND.
Check CHARG_CTRL line to GND.
