For any poor soul who happens to have the original problem stated at the start of this thread and happens to get to the end... I have scoured the internet for an answer to this problem and one is not obvious, so I'm going to share my experience. This problem is common for the DJI Phantom 2 Vision. At least, common to people who are stupid enough, (like me), to disconnect the camera from the back while the power to the phantom is on and then touch it with your hand. You will undoubtedly hear a "cracking" or static type sound coming from inside the phantom body. That is the sound a small resistor on the central board being fried. I didn't realize this until disassembling the phantom and there is really no information on the internet about it. It is obvious when you look at it what happened though. The resistor is really to small to try and change out, and there looks to be a fair amount of collateral damage anyway. What you have to do is replace the whole central board. Amazon has them for $59 at the time of this writing here:

My phantom is under warranty and I could have called DJI, sent it to a repair center, etc. etc. .. who knows when I would have gotten it back, and what a pain in the butt.
So anyway, I'm waiting for my new central board. And with the help of some videos showing some basic soldering technique, i think I can get it done pretty easily. I hope this helps and spares someone of the pain and agony of wondering what in the world has happened to the camera on their Phantom Vision.
