I got a Phantom 3 Pro a month ago, after I uploded the new firmware to the RV, I clicked on the on/off button to turn it off, and noticed that the "click" feeling you get when you push it.  After that I can't turn it on.  I think the button is not working anymore.  Any ideas?  

Hi, please try to charge the remote controller first. About the button, did you mean that the button can't  bounce up anymore? Could you please provide some pictures or demo videos to indicate your problem?
