1. Power ON

'Power On' does not work

Voltage >=3.3V

Download again

Charge the Battery

Pin#J12 >= 2.8V Check U102 and C128

Pin#A13 and pin#14

=2.8V Check U102 and C129

Freq = 13MHz

Vrms >=300mV

Vpp≒ 900mV

Check the clock generation circuit

(related to osc501)

Check the initial operation

END

Yes

pin#G11 =

1.5V

=1.8V

Yes

Check the current consumption

Check the Vbat Voltage

Check the pin of U102

2. Initial

Initial Failure

The pin #G11 of U102 =

1.5V and

the pin #J12 of U102 =

2.825V ?

Check the U102

(if it has some problem, it is to be replaced.)

Yes

Is the pin #K9 of U102

"Low → High" ?

Yes

No Check the U102

(if it has some problem, it is to be replaced.)

There is 32.768kHz

wave forms at the C218

and C219

Yes

Check the U202

Is the pin #A4 of U102

is "High"

The voltage is "High" at

the C122,C123,C127 Check the U102

Check the U501

LCD display is O.K

Yes

Check the LCD part

Sound is O.K

Yes

Check the Audio part

Check the voltage at

pin#1 of CN101 >=

2.8V ?

"Insert SIM is displayed on the LCD

Check the SIM

connector's (CN101)

connection to SIM

card

Check the U102

Resolder or change CN101
