I'm working with a RasPi 4 (2 GB) since a few weeks mainly as media center (LibreELEC).
Yesterday I was experimenting with Raspbian a bit and the problem began:
When trying to shutdown I realized the Pi is not shutting down completely anymore - connected fan still blowing and ethernet still blinking, rest seems off. Reboot still works fine.
I tried to switch back sd cards, tried again LibreELEC and Raspbian, completely new installation of LibreELEC, another power supply, disconnecting fan, hdmi and ethernet but still no shutdown.
Did anyone have the same problem or has any idea what else I can try? Or is it a technical issue with the RasPi?
