pastekodi -c >my.log
no chance but
"journalctl | paste"
worked.
I don't know if it makes a difference if the TV is off during boot but as I switched it on, no image was coming up, so I booted it again with the TV on for a short while.
- ix.io/4izB TV was off
- ix.io/4izI TV was on until roundabout 09:56:45
if there is nothing in the logs that tells something I continue with #12
