By the style, there is no definite way to prepare this problem it is trial and error, and then let us offset off with software troubleshooting before you lot go to replacing hardware part or earlier sending it to a professional.

Last choice

If none of the methods fix it, you might have to send it to a professional

I don't know what your take on this or your upkeep merely for the price of Ryze Tello I wouldn't consider sending it to a professional person because the cost to go information technology fixed won't probably match the price of the drone and in that location is a high chance it will have another issue once you go it stock-still, which at that point y'all are better off ownership another drone, but that is my opinion.

You can, however, try to gear up information technology by yourself and it would be a dandy experience.
