Log files
Link to logfile(s): Do not have any. But I am trying to create one today.
Problem description:
All my devices are connected to a switchable electric socket. The devices are REALLY powerless. But the RPi is connected to a differenct socket which stays on. If I want to look TV I have to put on the socket and swtich the tv on. There was never a problem but since a few month, xbian stays black. I still hear the sounds the menu makes when clicking on my tablet (using yatse). I also can start movies. So kodi reacts on input. I can login via ssh aswell and any other services like apache works just fine.
My TV does get a signal because it is not telling me "no connection". I am running a black screensaver (still having an old plasma TV which can burn). Normally kodi just fades in the menu when clicking a button in yatse. But it does not if the TV was powerless. If I turn the tv off and on again (without switching of the socket), everything is visible. So it seems to be an issue with powering off. I had the problem with kodi 14.2 and still have it after upgrading to 15.1.
I am still trying to determine which device is the true problem. Could be the splitter as well or the hdmi switcher. But as I said, this problem exists only since a few month. There was never a problem before.
How to reproduce:
I just have to really switch off the tv (powerless not standby, what the most devices do) and switch it on again. But I am still trying if I have to wait some time between switching off and on. Cannot do it right now.

I added the logs as attachment. Pastebin does not allow me to upload it because it exceeds the 500kb limit.
I also found some video flags. I noticed a lot of cec messages in the log and tried to disable cec and overscan via xbian-config in the console. But it only let me disable overscan. In the same list: What are
- force hdmi output when no tv is identified
- ignore hdmi output even if a tv is connected
