Note 3... zero signal after drop topic

My phone (tmobile note 3) fell on its back after which I have had zero signal (0 db and circle with line through it) since. I bought it used so I did a ESN check and it came up clean. I took it apart and everything looked fine and the antenna was connected on both boards.


any ideas on how to figure out the issue?

I could replace the board if I knew that was it as I have a bit invested in the phone and its still in mint condition I would like to use it until the note 5 comes out.

Thanks any help is appreciated.
