when you say flight controller which bit is that ?
The Naza/Phantom flight controller. The big orange box inside that says Phantom on it.
I'm not sure where it plugs in though. I don't think there is a direct connection between that and the camera but the camera has a serial data connection with the controller somehow, probably via the CAN bus.
It's the smaller of the three cables from the camera. I'm sure you know better than I do where that connects since you just replaced the cables.
Wherever the smaller connector goes, that's where your problem is. Make sure it's plugged in securely on both sides and double check that the connectors aren't damaged.
