Here's how i fixed my No Image Transmission Signal issue i had with my DJI Phantom 4 drone. The key step for me was removing the SD card and restarting my drone without the SD card in it. Before this, i had tried reformatting the card while the image wasn't being transmitted and the reformat wouldn't complete. I also tried removing the SD card without recycling the power, but this had no results.
Remember that reformatting a card will erase everything on it. Transfer any footage/data you want to keep to your computer before reformatting.
