플랫 케이블이 포함된 DJI Mavic 2 Pro/Zoom 짐벌 카메라 보드 정품

I received the part looking like it was dug out of the bottom of a trash can. The thermal paste was dirty and it was all over the board including inside some of the ribbon cable connections. The part does not work. They said I need professional software. I have it and I did use it even though it isn't required for this part; there was no change from before flashing to after flashing. They wont accept my exchange request. I tried the part from another source. That one is bad as well. So now I have 3 bad gimbal control circuit boards that all fail in completely diferent ways. I had this same problem with this same part on a diferent drone about 2 years ago. It took 3 tries before I got a good gimbal control board. Unfortunately in this world of used DJI parts supply, this is often the case and Jangyao should know this. Im very let down by their customer service. I have purchased many parts from this company. It is a shame they wouldn't even exchange the part let alone refund my money.
