TL;DR *blank screen* -> "Intel NUC" -> *blank screen* -> "NO SIGNAL"
Hello everyone,
yesterday evening I turned on my Skylake Intel NUC (with LibreELEC 8.2.1 installed) just like countless times before, but instead of a logo I'm now being greeted by the dreadful "NO SIGNAL" message. This is especially odd, because for a moment I can still see the "Intel NUC" line of text (and even access the UEFI setup) just fine, so there's nothing wrong with the TV settings or HDMI connection, I assume. I can log in via SSH, too. "xrandr" also shows sane resolutions (please see attachment). It all appears as if nothing's wrong, except there's no output on HDMI once LibreELEC boots. 
In the meantime I've manually updated to 8.2.2, hoping this would somehow solve my issue, but with no avail. I've also connected the NUC to a different display with a different HDMI cable, just to be extra certain it's something wrong with LibreELEC, I guess.
Where do I go from here to debug this issue? 
Thanks in advance!
