Dear Phantom 3 experts!
Please see the attached image. The gimbal wobbles and cannot align (the app says "gimbal motor overloaded"), and the camera only shows interference.
Any idea what it might be? Could it be a problem with the black ribbon cable? I replaced the white ones, and still no effect.

For those who might find it interesting: the problem was caused by the black band cable on the gimbal: either use the genuine one or check before you buy.
