Yesterday I called my Phantom 4  usually the image does not appear (black screen) ... and the message "CAMERA SENSOR ERROR" appears ... the drone has never crashed or suffered any accidents

Hi, we're sorry for the inconvenience. I would like to ask if you've managed to update the firmware of your aircraft and remote controller? Did you try to restart the aircraft multiple times to see if the error message would persist? If so, we highly recommend contacting our support via the link below for a further evaluation of your unit. For further information, the repair fee would depend on the warranty period of your product and the outcome of the damage assessment. We do appreciate your understanding.
