Hi Guys,

I have an MSI Cubi I5 running Ubuntu Xenial and Kodi Krypton RC 3.
My previous TV was a 5 year old 55" TCL (Model escapes me) and worked flawlessly with my pulse-eight CEC injector.
I've recently upgraded to ua55ks9000wxxy. Unfortunately, my CEC injector seems to cause problems with this.

The TV will blank the display, show 'no source' for about 10-20 seconds, then briefly show the kodi box, before repeating the process endlessly.
I typically have a soundbar connected via HDMI ARC, however after reading about potential issues with this configuration I attempted with the soundbar disconnected as well.

Logs from my latest attempt with cec-client (Kodi unloaded) are here.

I don't suppose anybody here has any suggestions?
I did notice by punching the comms messages into http://www.cec-o-matic.com/ and noticed that the message '10:9E:05' appears that it might be related.

Edit: Moved logs to hastebin.

Thanks nickr, Logs moved.

I realized in retrospect this is probably more suited to Discussions -> Hardware -> Peripherals. Any chance we could have this moved?

Updates on this issue:

I tested this on my old Intel NUC (DN2820FYKH), and the CEC controller was stable and did not cause the picture to die.
As the DN2820FYKH has a max resolution of 1920x1080, I dropped the resolution on the Cubi to 1920x1080, and CEC became stable.

At this point I assumed it might be an issue with the CEC controller @4k resolution, however I then attached the CEC controller to my laptop, and started kodi from my laptop at a native 4k resolution, with no CEC issues.

It seems as though this issue may only be present on the Cubi @4k resolution (I cannot explain why)

All systems are running Ubuntu Xenial and are now upgraded to Kodi 17 stable release from ppa, and libcec4 latest from ppa.
