4. Basic flow chart of familiar troubleshooting (level 2)

4.1 Switching on failure

Repair steps:

♦ Download software again

♦ Measure whether the output voltage of system connector (pin 1) is 4.2V, replace the connector or related ESD overvoltage protectors or power amplifier if the output isn’t 4.2V

♦ Measure whether the output voltage of R89 and VD6 are 4.2V, connecting PM with power supply if the output are normal; if not, check the solder of VD6

♦ Check the output voltage of P, C, and A in baseband when PM connected with power supply. Solder PM again or replace it, if the output isn’t normal

♦ When the power supply of C is normal, check whether the PS_HOLD signal is high voltage (R130 is high voltage or not); if it’s high voltage, solder a 10K resistor on the plate, and then check whether the handset can be switched-on. If switch-on successfully, solder SM6000 again or replace it

♦ Measure whether the PS_HOLD is normal, please Measure whether the PM_RESET signal of R38 is normal; if the signal isn’t normal, solder PM again or replace it

♦ Measure whether the output voltage of R32 is 2.85V, if it is, check whether the frequency output of GR1 is 19.2M; otherwise, solder GR1 again or replace it

♦ Measure whether the output of sleeping clock is normal



♦ Replace main chipset or FLASH, if the failure still exists after the steps above

4.2 Automatically restart

Repair steps:

♦ Download software again

♦ Check C110/C111

♦ Measure the pin 1 of G1, check whether the sleeping clock is normal (test the signal when you just switching-on for an instant, if you test after switching-on ,the handset will restart), the normal signal just like a 32.7K sine wave, if not, solder PM again or replace it

♦ After input test, measure whether the output is a 32.768K sine wave, if it isn’t, solder sleeping clock or replace MSM6000

4.3 Abnormal vibration

Repair steps: ♦ Measure whether the VD1 is normal, and the C2 is broken to the GND

♦ Measure whether the VIB_DRV signal is low voltage output, solder PM or replace it, if the signal always be high voltage

♦ The failure still exists after solder or replaces PM. Solder or replace the main chipset



FAQ:

♦ The VD1 is broken

♦ Vibration failure may caused by wrong setting when install the cables, please reconfigure

4.4 Abnormal LCD display

Repair steps:

♦ Check the solder of LCD

♦ Measure whether the output signal of LCD_BACKLIGHT is normal, check the main chipset if the output isn’t normal

♦ Check whether the drive chip (D5) output of LCD is normal

♦ Check whether the voltage VRFG_MSMP of LCD is normal

♦ Check whether the chip select signal, reset signal, and ID of LCD are normal. If they are not, check the resistors and Capacitors of LCD

♦ Check the main chipset

FAQ:

♦ Black display or display failure usually caused by the solder problem, check whether the LCD_FPC is poor welding firstly

4.5 Vibration/ringing tone failure

Repair steps: ♦ Check the solder of SPK

♦ Check ESD overvoltage protectors (FV1)

♦ Test whether the input signals of audio power amplifier (FF_SPKR_P, FF_SPKR_FN) are normal, these signals are from main chipset

♦ Check whether the output of audio power amplifier is normal, solder again or replace

FAQ:



♦ Vibration or ringing tone failure usually caused by weak setting, reconfigure will repair the faults

♦ Vibration or ringing tone failure caused by weak elasticity of touch points

4.6 SIM card unidentified

Repair steps:

♦ Check the solder of FV3 and UIM card connector

♦ Test whether there is output from VREG_RUIM when just switching-on for an instant, if the output isn’t normal, solder or replace PM

♦ Test whether the input of UIM_RESET, UIM_CLK are normal, check the related filter of resistor and capacitors

♦ The failure still exists after all the steps. The UIM card connector must be broken

4.7 Earphone failure



Repair steps: Recognise earphone failure.

♦ Check the solder of R2, C4

♦ Check the solder of earphone connector

♦ Measure whether the JACK_SENCE_N signal is normal, solder main chipset again or replace it, if the signal isn’t normal

Hang up/answer the phone failure by earphone

♦ Check the solder of earphone connector

♦ Check the solder of R79, R81, R82, R83, and R85

♦ Check the solder of FV2

♦ Replace the earphone connector

FAQ:

Earphone failure when connecting

♦ Measure whether the output voltage of earphone open circuit is normal, except the weak touch of earphone connector

♦ Measure the solder of earphone circuit components



4.8 No echo/transmitted/receive voice

Repair steps:

♦ Replace the MIC

♦ Make a phone call and test the failure from transmit circuit or receive circuit

♦ Transmit circuit failure. Check the related filter components of MIC

♦ Receive circuit failure. Check the solder of FV9

FAQ:

♦ No echo usually caused by the poor welding of the components from MIC circuit

4.9 Abnormal key

Repair steps:

♦ Check the failure caused by keypad or keyboard

♦ For keyboard failure, key-press failure, and abnormal key, measure whether the DOME is clean well, clean it



♦ Check the solder of keyboard connector ♦ Check solder of keypad and the limited resistor ♦ For mainboard failure, consult “switching-on failure” to deal with the failure FAQ: ♦ Abnormal key or key-press failure usually caused by poor welding of keyboard connector

♦ Parts of key-press light failure usually caused by LED light failure or poor welding of limited resistor
