Patrick,
There are several primary areas that need to be discussed to even know what to look at:
1.) The drone side (spring) mount contacts.
2.) The camera side mount contact.
3.) The circuit board in the top of the camera mount.
4.) The slip ring.
5.) The camera gimbal board.
6.) The drone main board.
7.) The connector board above the drone side of the camera mount
8.) The wires and connectors that tie them together.

You have checked the spring contacts on the mount, which seems to eliminate item 1.
You have indicated the circuit between the top of the camera and the slip ring connector on the gimbal board is good. That seems to eliminate items 2, 3 and 4.
Items 5 and 6 will require inspections that are not easily done, and may not be possible via Forum messages. It is not practical to invest time and effort into these items until all other items are eliminated.
That leaves items 7 and 8.
Items 7 and 8 can be eliminated by doing a continuity check from the back side of the connector on the Drone mainboard all the way to the slip ring connector on the camera gimbal board. Attachment 60 mentioned in the earlier posts will show which of the gray wires inside the shell correspond to the each of the colored wires at the gimbal board.
Please understand we cannot proceed until we know the results of this continuity check.
Hello,

to day j try the another motherboard to aircraft and its same problem, So I think that the camera fault. I check tomorrow if there is indeed a signal on tx / pwm (green white wires) with an oscilloscope.
have you a electronic scheme to this part of camera ??

Is the other motherboard bound to the controller? The tilt and pitch are not the same radio signal as the camera video. They will not work unless the drone (motherboard is bound).

I do not have an electronics scheme for any of this.

OK, this last picture is very well,
the last image is the correct one, the connection between the resistor and the cpu is broken, dry solder on the resistor and cpu side and its OK, thank you very much for this help.
