Have you gone through the power saving options on the TV? I just looked at the Menu -> System -> Eco Solution, and I note Auto Power Off is set to Off (default is on, goes off after 4 hours of no activity). It's more than two years since I bought the TV and set it up, but seeing that I now recall that I had to set it to Off because I found the display dead if left overnight. Had no problems since.
I don't think it affects in this case. The TV was switched off manually. On the morning I switched it on and the TV program came up. Then I told it to use the HDMI input instead, coming from the miniPC, and this one was dead, no display. I have now been reading the log, and nothing wrong there.
