Level 3 Repair
Check the Battery Voltage.
Is it more than 3.8V?
Yes
Power-on the phone and
check the power-on sound
or motor Vibration.
No
Check the PWR_KEY
(soldering crack, open, etc)
Yes
Check the C401, C402, C403,
C404, C405, C406,
L400, L402, L403, L404. L405
Yes
Check the Clock OSC400
Is that frequency 32.768Khz?
No
Yes
Abnormal
No
No
Charging the battery by TA.
If its voltage level is extremely low(under 3.0V),
Change the battery.
Change the FRONT-LCD ASSY
Check TAC500
(Damaged or not)
If the output voltage is not satisfied with normal
condition, Replace U401
or find the de-cap related power
Each voltage level has ±10% margin.
※
Change the OSC4000
If OSC4000 does not still work, Change the U4000
This problem is internal oscillator of U4000
Test condition (Oscilloscope setting)
Yes
check the initial operation
