samsung c3312 mic problem solution

Here's another solution for samsung c3312 mic problem. Previously we show you the samsung c3312 mic problem solution, this time we got the samsung c3312 mic part to tackle with. 

In this solution shows the connection line paths of the samsung c3312 mic

 and its components.

You can use this to troubleshoot if the there is no any audio can be heard over the Mic, like ground. You may locate the components that I highlighted on below picture and check that certain area for possible damages might occurred. The mic is replaceable and fixing this kind of problem was not  that much hard enough. This problem may only sometimes happens if the device suffered wet damaged and or accidentally heavily dropped. 

Hints to fix samsung c3312 mic problem:

1. Check the mic assembly for possible damaged and or misaligned. Use a multimeter to check i, replace if already busted.

2. If the mic is okay, check and clean the mic terminal contact pads. Corrosion might weakened and loosen the connection.

3. Trace the pints- connection to each certain components where it is being connected.  

4. Check and replace the filter capacitor and resistor components.

5. If the above method doesn't fix the problem, the possible defective part is the mic ic & chip.

Reworking or replacing  it might only fix the problem, but that tasks needs a good soldering skills. So, don't touch that chip if you have not enough knowledge in reballing a ball grid array (BGA) chips.  Particularly that IC for it also holds as the power integrator of the whole circuit. 

That's it., Enjoy!
