Member: 1133 Status: Offline Thanks Meter: 38 | N70 Camera Problem. Unexpected error occured.Power off the device and restart. Anyone encountered this problem before? Phone is water damaged. When I place back cover and slide it down to use Back camera, I will get error message "Unexpected error occured.Power off the device and restart." However when I DO NOT put back cover and camera is in front camera, it is ok. (After I restart the phone.) I have tested voltage of C1472(4.0V), C1473 (1.5V), R1475 and J1471(1.8V) and seem to be ok. Is it ok for C1473 to have 1.5V since in the service manual, it is suppose to be 2.8V? I checked with 6680 service manual which uses the same N7505(LP3990LDX-1.5NOPB), the correct voltage is 1.5V. Anyway, I have replaced N7505 as well. I have also replaced Camera. Other test is TAHVO to R4408(VIO=1.8V) to S5202 is correct. |

Member: 1133 Status: Offline Thanks Meter: 38 | Hi reji, Problem solved. It is not a faulty "Level Shifter" (N1474) but just bad contact at I/O_VB1 and I/O_VB2. Thanks for the tip. Cheers. |

Member: 1133 Status: Offline Thanks Meter: 38 | refer to the schematic and look at N1474. You will see the names of the track there. |
