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.
