RESOLVED: HDMI was plug but not pushed.
I´m noob in this and probably has a easy answer, but I´m spending a lot of time to try to turn on again the raspberry after used the turn off button in Kore from my Smartphone.
I try to unplug and plug power cable, to use Kore to wake up, to conect remotely from my computer, but nothing works. TV indicate HDMI is without signal.
This is my last try before install it again…. someone knows how turn it on again?
Thanks a lot in advance…
