motorola B11 Memory Card problem.memory card not detected Solution

UNIT:motorola B11 (android) 

PROBLEM: memory card not detected 

Here's another solution for motorola B11 Memory Card problem. Previously we show you the Memory Card problem solution, this time we got the Memory Card part to tackle with. 

In this solution shows the connection line paths of the motorola B11 Memory Card and its components.

You can use this to troubleshoot if the there is no any audio can be heard over the Memory Card, like DATA. You may locate the components that I highlighted on below picture and check that certain area for possible damages might occurred. The Mmcis 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 motorola B11 Memory Card problem:

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

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

3. Trace the mmc box- 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 mmc 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!
