No HDMI output after power off. Works after reboot

Hello, I am having an issue with OSMC on raspberry pi zero. Everything works perfectly…except for the power off feature.

Every time i power the device off from the menu, remote or from ssh (shutdown command). the device turns off. on power on, it does not produce any hdmi video output. Three different screens (a big LED digital signage panel, a normal hdmi screen, a portable hdmi screen…none works) and the same result. When in this “state”, web interface is perfectly working. ssh over wifi works great too. If I login and give a “sudo reboot” then everything starts to work. Any idea what could be the issue? Thanks!

The device doesn’t implement ACPI.

If you turn it off like that, you’ll need to turn it back on manually at the mains
