I have a phantom 2 on firmware 3.04. I decided to paint my P2 and dis-assembled so that I could tape the insides preventing overspray. After re-assembly my P2 will no longer power on. As soon as I turn on the battery, all motors kick one time, all led blink once and I hear one quick chirp and the battery turns off. I have rechecked all connection and removed all accessories and still have the same result. I can not connect the assistant software to for diagnostics, so I have no idea what to try. I appreciate anything suggestions that you all might have.
