i read "jasonisdn" post and i didn't really understand how should it be and how he got the cable .
you can see in the pic i attached before how my cable is connected to the board .
as far as i know this is the correct way no ?
The component that short it out is connected to the B+ power and connected to the camera socket right in back of it. Why that component shorted you either used the wrong plug n play cable or solder the power wires incorrectly. This had nothing whatsoever to do with unplugging the gimbal. No matter how it happened you will need a new mother board.
If you list what transmitter you have and where the iOSD is installed so I can point you the correct plug n play cable. A photo of the bottom of your P2 would help
