Power supply chip damaged, apache can't power on.

---

Hi,

I can't power on my 6700. Battery is about 4.2v, so it should be OK. When I push reset with both battery and usb pluged in, the RED light flash.

After I carefully checked the main board. It seems that *Power supply* chip damaged, the chip starts with part number:

"AZU6...."

I can feel the heat when I move My finger over the chip right 5 seconds after I plugin USB cable.


After hours of search:

I can't find any of the information related to AZU6 online. But I found several similar chips, all are packaged with 10 feet.
