@m5stack , @ajb2k3 sorry but any ideas?

Hi everyone , so my m5stack fire suddenly become black screen after I connected servo motor to it .

this happened before like month ago so I tried to update the firmware and it worked and back to normal but this time when I connect it to my laptop and update the firmware it doesn't work and fail.

btw it only make some sounds and the red led lights but the screen is black.

also can I know why when I connect it to servo motor this happens?

thanks
