This happened on my Phantom 2 v2.0.  I fly this with a Zenmuse, GoPro & FPV.

  

Over time, the antenna wire wore through the protective layer on the central circuit board (see pics below).

This happened while I was flying, my Phantom lost all GPS satellites and became hard to fly.  While I was trying to land it, I noticed the rear lights were solid red.  Swapped out many parts before noticing the circuit board had what appeared to be an electrical burnt area.

  
I was able to swap parts from an older Phantom 2 and that's how I confirmed the problem.  I did put a piece of electrical tape and I noticed the other board had a DJI sticker right where the wear point is.
