USB Video Out - Input Voltage

Hello ifixit Forum :)

I was trying my FPV setup from my quadrocopter and wanted to attach my GoPro with an USB - Video Out cable. I accidentally have attached

(FPV Transmitter -> GoPro)

GND - GND

12V - Video Out

Video - Audio (would should have nothing bad)

Now my GoPro is dead. Is this fixable? Has anyone a schematic layout of the GoPro?

I will attach a picture of the GoPro tonight.

Thanks in advance,

Patrik

Ok seems that my power unit broke down (AS3713). This part is barely to get.

Now I'm looking for a new mainboard Unit, is the Hero3+ Black mainboard the same as the Hero3 Black mainboard?

Thanks
