Re: GoPro Hero 9 Black Screen going crazy and Flickering![ New ]
What was the last activity done with the camera?
Do you observe the same when the camera is powered on without the SD card?
See if re-flashing the software will help. Follow the steps on https://gopro.com/en/us/update/hero9-black
Once done, reset the camera. Go to Preferences> Reset> Factory Reset
Let us know how it goes.
