Phantom 4 camera wobble none stop wont center?

I need assistance! I've downloaded a You Tube video
. This is the problem i'm having the camera wont stop wobbling and reset to home. I've switched a esc gimbal power board and the ribbon cable and the problem still stayed the same. Where to go from here? I tried to contact DJI tech support and they wouldn't talk to me (lame) just asking for guidance. So if someone has had this problem and can throw in a little help I would greatly appreciate it.
