Hi,
after the update to LE v8.x I have sometimes a black screen on my TV.
It's a Intel based HTPC connected vi HDMI to a Panasonic Viera TV.
There is no boot sequence visible on the TV.
After waiting some hours it works again.
The box is used in the living room - the family is not happy 
Any ideas?

"Sometimes a black screen"
Could be anything... A HDMI cable with hair fractures or some other hardware failure.
I'm not yet convinced it's a software problem.
Start with giving us a kodi.log file.

Also please be sure, you turn on the TV as the first device in the chain and the HTPC as the last device. If you turn on the HTPC before the TV is up and running, the HTPC tries to read the EDID informations from the TV (which are not available at that moment probably). If the HTPC can't read the EDID informations it will disable the HDMI out and you won't get a screen.
So please confirm working/non-working if you turn on the HTPC as the last device. If that works, we will go further and do something to fake a connected monitor. But we need to know it working first, because it might also be something different.
It is likely a Intel GPU problem, I have basically the same behaviour (it is getting worse and worse since LE7).
To "fix" it just run the edid script, fixed it for me.
