first u have to open ur phone first, i don't describe how to open it anymore, after opening it, u will see 2 board which connected to each other with a cable flexible, the bottom one is called rf board and the top one is called the mmi board, carefully separated this 2 board, in this charging case, the defected area is at the rf board, from the side which has two yellow can covering area u must find a tiny and white looking part, this part is located at the bottom area (located near the power spool-a round shape ferrit and has wire rounding it), this small and white part is the charging fuse, test this part with ur multitester, if it's not working anymore, just soldering it to make the phone charging again
But sometimes except that white fuse you will have to change also ic with 6 pins located above that fuse

Or you can try to check your plug in connector. <img src="biggrin.gif" border="0">
