Issue with inspire 3 camera

Hi friends, I have an Insipre 3 drone, which wasn’t crashed or damaged at all, but the main camera’s picture is gone. I have the same drone and I swapped the gimbals, but getting the same issue. At the start the picture was on for 1-2 minutes and after turning off, but now it’s not turning at all. The problem is in the drone, all the updates are done and it doesn’t have any technical mistakes. The gimbal is doing all the movements, but the picture is gone. Please help, maybe someone faced the same issue.
