Hello, there is not a single electrolytic capacitor on the board of my mavic air. Perhaps someone knows what it can be replaced or where to find the original, perhaps someone has the characteristics or circuit board. On the board there should be 4 such components, on the other two it is written N7 C 28 09. P. s photo from the Internet, so it has this smd. I would be very grateful for any information.

Hello there. Thank you for reaching out and for these information you have given. Since you are having issues with your DJI Mavic Air. I would be best to contact our DJI Support Team at ( https://www.dji.com/support ) for further assistance.  Just a reminder that DJI do not recommend doing a DIY in fixing the said DJI drone to avoid further damaging the said unit. Again, I am sorry for the trouble this has caused and thank you for your understanding.
