one of the green flashing light is out on my air s 2,  do i have to send it in to get repaired ?

I've had a couple of repairs done through DJI and found the prices to be very reasonable.  

Sorry to learn about this. I suggest to sending it back for repairs. We do not suggest to repairing the drone by yourself as this may void your after sales service policy if your drone is within the warranty period. To ensure flight stability and performance, we suggest sending it back and have it repaired at our facility. If decided, please register an online repair request on our official website. Hope this information helps.
