Splash screen then no signal

OSMC has been working well for a year, so I brought the device on vacation.

Device boots up with message:

waiting for root filesystem device /dev/mmcblp02
/dev/mmcbl0p2: recovering journal

Then displays the OSMC splash screen and then the display indicates no signal.

The pi responds to ping / SSH login.

dmesg: http://paste.debian.net/704020/

  • Has anyone seen this problem?
  • What is the next-step for diagnosing root-cause of issue?

I have not compared the dmesg with a working one (no easy access from here) but this looks suspicious
3.953952] systemd[1]: Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory.

While that indicates that you had an unclean shutdown but it should not impact the Kodi display.

  1. Have you tried to use a different HDMI cable?
  2. What do you have in config.txt? cat /boot/config.txt | paste-log
  3. Also what is the output from

tvservice -s
tvservice -m CEA
tvservice -m DMT

  1. Provide full logs via grab-logs -A
  2. You might want to install VNCserver to see if Kodi is running and which Video Mode used

No that is a normal warning on all OSMC systems

Thanks for the good diagnostics commands. I am interested in how you interpret these / what you are looking for to diagnose:
