Hello,
Sorry to hear about your phantoms. I have one also and was hoping you might be able to help me out. I had a chip fall off my circuit board and was wondering if you could take a look at yours to identify what the chip is. If you would, the chip that I'm looking for is soldered directly above the antenna. It is black in color and about 2x2x2mm in size.

I am trying to find out what it says on the chip.

Thanks for any help you can give.
