Controller board arducopter burned?

Hello. I have a query. I was testing a new receiver PPM and at a time when I plugged my arducopter 2.8 to your computer, this is turned off.
The following symptoms were: Lights up solid / fixed. Additionally, the computer does not recognize as before the controller board. On the other hand, and more worryingly the plate is hot. Since no weapon from the station. I tried to reset the button and the jumper J1 but has not worked.

someone else?
