So appearently my NUC suddenly decided that it won't output over HDMI anymore.
My half a year old NUC which i'm running as a media center worked fine until now. I turned it on as usual but the screen stayed black, the NUC itself seems to be working fine (power led, hdd led, lan led, i can access it over lan).
The things i tried with my limited recources are: cable in/out, cable plugged into different ports on my av receiver, cable plugged into different ports on my tv.
Both tv an av-receiver are telling me there is no signal.
So what could have happened?
