Hi, I upgraded to the latest version (3.779) from a previous V3 version on RPi3+B with 7" official touch display.
After the upgrade the Touch Control plugin was no longer working, so I uninstalled and reinstalled it and it was fine.
After a few days of proper operation, I noticed that when I turn on the system (which I do from the power supply switch) the screen remains off, it does not even display the initial logo, as if it were electrically disconnected.
However, the device works and resumes the last song or station it was playing since I installed the Autostart plugin.
If after this “start in the dark” I restart the system from the web interface or the app the system restarts and the screen works properly.
Can anyone help me solve the issue or direct me how to investigate the causes ? Thank you.
