Typically, ‘SD ERR’ or ‘NO SD’ message on your camera’s LCD screen means that your camera can't properly communicate with the SD card. Make sure that the recommended SD card is fully inserted in the camera. Power on the camera and verify that "NO SD" is still displayed.
If the camera still displays "NO SD," format the card using a computer. **NOTE: Ensure that you back up any pictures and/or videos before you proceed any further to prevent loss of footage.
If the suggested troubleshooting doesn't resolve the issue you're seeing, there could be a problem with your SD card or an issue with the camera recognizing SD cards. If available, try inserting a secondary SD card in the camera to see if it will recognize a different card and narrow down where the issue is coming from.
Hopefully this helps!
