Nokia C3 MIC mouthpiece microphone Solution
This solution may works to fix a damaged Nokia C3 Microphone that result to "No Voice Sound can be heard on the other device when making a call.
If ever encountered this try to update the device flash firmware first before proceeding to hardware troubleshooting.
If the flash firmware is successfully been done and nothing happens: The solution below will you which particular circuit components on Nokia C3 PCB board that needs to be check and replace if found damaged.
From microphones audio signal which is the "voice being picked up" is being feeds to the AD-DA processor chip (JUNO) and there are corresponding components that also connected to it. Like, the filter coils, capacitors and resistors.
You may need to check this components first and then replaced if found damaged.
If all of these components seems all perfectly working, you may then proceed to replace the microphone module.
There is an instances that you may need to rework the JUNO IC after ensuring that of those corresponding components including the microphone module seems all working but still the problem exist.

Nokia 2710NE Memory Card Solution MicroSD Card not detected problem repair solution
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.
