Had a crash with dji air unit.  The unit powers up but shows no image.    Can I sent it in for repair?  Is it worth the cost.  I tried to enter the serial number but the product was not found .

Hi there, sorry to read about the accident, you may send the air unit back to DJI for further assistance. Regarding the process of starting an online repair, you can continue by selecting the specific product instead of entering the serial number. If you have any further questions, please feel free to ask.

Have you checked the connection between camera and air unit?, maybe a socket out of place, maybe the camera went bad,....
You can find the serail numbers for camera and air unit in the menu from your V2 Goggles

HDPS, that was the problem.  Thx dude !
