3.if I connect drone with pc (to usb slot on gimbal) nothing happens
4. no image on screen
5. update requred -battery firmware


when I power up unit:

1. gimbal moves does his little dance,... reacts to movement etc.

Sounds like a failed top board, contradictive as the gimbal does the dance i know, but the top board has 2 functions, 1 is the video side of things and the other is the gimbal movement

Gimbal board right? Thats my idea also.
Since I get power from motherboard of the drone (little gray cable 8 pins) it must be issue with gimbal board. I even know why.... drone had issue with IMU, it could not be calibrated. I got it with that error... changed the IMU and thats fine now. I guess previus owner tryed to solve imu and fryed the gimbal board.
Does anybody have gimbal board to sell?

You seem to have issue with Ambarella chip. The chip is either not powered or dead.

The whole gimbal+camera does get 12V from main board since gimbal moves. So either buck converters which power Ambarella are damaged, or Ambarella itself.

Buck converters can be verified and fixed by any electronics repair shop.
For Ambarella, it's harder, and only proper repair shops could fix it - at least physically, because for reflashing its software I haven't heard any success story so far.

You may try searching for a refurbished board in china - people there were repairing and reselling boards, maybe they still have some. In general, Gimbal Top Board is the usual point of failure, so it is the hardest one to get.
