I had the same happen. pulled a wire from the back side of the board. Cant just buy the part from Yuneec. UGH. I had to send the gimbal to the factory. I haven't heard back on the status. If the factory can't repair it, I'm thinking of trying carolinadrones.com and maybe they sell the board. Seems to me a person should be able to buy ANY part from the "manufacturer" Oh well.....
