No power to GoPro (H3-3D, GP3 silver)

[Hyssy]

Hello guys,
I have a problem with my p2 h3-3d setup. I recently bought 2 new (genuine) batteries and have updated firmware on both of them and each has 3 discharges on them. The problem is that one of the batterys will power the gopro through the gimbal and the other will not. I also have an older battery that i rarely use and it too does not power/ charge the gopro. Is there something i can do to the firmware etc to fix this. I have updated it on all 3 but have come to a dead end.
I hope this has not been asked too many times, but i did a quick search and couldn't find anything.

any ideas appreciated.

If the gimbal still works with all batteries but the camera is only charge by one. I'd say you have an intermittent ribbon cable as the power goes through the gimbal which in turn feeds the camera.
