When the MicroSD card inserted on the device and nothing happens but it displays "memory card not inserted" something like that, this solution may help fix and repair the problem if the Nokia 2710 navigation edition has been damaged by any means like wet damaged or accidentally dropped.

The solution below shows the particular SMD components that needs to check, trace and replace to possibly fix the problem.


Repair tips:
1. Check the MMC card detection switch first, you can read a voltage on that area about 1.8 volts if unpressed and 0 volts if pressed.
2. Check and trace the MMC supply voltage it is marked with VSIOD and connected to MMC socket pin #4 then the pin #6 for groundings.
3. If both MMC power supply voltage and MMC detection switch is okay, the problem may lies on the ESD-EMI filter chip. Replace the ESD filter if necessarily.

This solution shows the camera module circuit of nokia 2710 navigation edition. If the camera failed to initiate, this solution might help fix and repair the problem. If already tried to restore its firmware but the problem still exists, this solution shows the tracks of the Camera module supply voltages that needs to check before attempting to replace the camera module assembly.




There are three power supply voltages that makes the camera module works and operate if one of these voltage were missing the camera  will not function, and it shows camera hardware failure, camera on standby and either no reactions or indication at all.
A Camera on standby mode may fix by restoring its firmware. If an empty or black screen showed on the LCD display screen,  the problem may lies on the camera module itself, replacing it will possibly solve the problem. So first ensure that the firmware is secured before proceeding to hardware troubleshooting.
