E72 not charging pro help

1. check the charging pin connector, free from dirt or corrosion, if the pin is damaged find a new replacement charging pin.
Make sure that charging pin contact pads is also clean.

2. Check the fuse continuity by using a multimeter, if found open or damaged replace it. check the diode if shorted, shorted diode will make the fuse blown again, replace if found shorted.

3. check also the filter coil. Sometimes the filter coil might also get damaged if an extreme short circuit occurs like water damaged device.

4. check all the corresponding charging line paths from the charging pin terminal pads across to each corresponding components connections. Apply a tiny jumper wire on it if found cut or open.
