TV says no signal received when kodi box is first turned on

Single Board Computers Odroid N2/N2Plus/C4

Hi
I run kodi (as coreelec 21.2 omega) on an odroid n2+ and it is connected to my TV (Hisense Q8) via a yamaha a860 receiver . I’ve been running kodi successfully without issues for years now with this arrangement but recently I’ve been having an issue where I turn on the kodi box with my TV remote (HDMI CEC) and both the receiver and TV come on correctly but my TV says no signal received (despite the receiver being on the correct input). When I switch to a different input on my receiver and then back to HDMI, kodi then shows up but HDMI CEC doesn’t work on my remote so I can’t control kodi with my TV remote. I didn’t change anything recently that would explain why this is happening. Can anyone help me troubleshoot the problem?

Sorry if my explanation of the problem is poor, I’m happy to provide any other details requested

TLDR: TV says no signal detected when turned on despite previously showing the Kodi UI straight away. I need to change inputs on the receiver, or start playing something using the Kodi app for it to correct the problem

Leave KODI always on.
Try the test again.

3

Try CE22-NO.

If it turn the TV off with the kodi box on, the kodi box turns off too due to HDMI CEC so I can’t leave kodi always on

You can configure it.
My N2 is running 24/7
Switching TV of with TV-remote switches off my AVR, but N2 with CE/KODI is still running

6

Do you know how to configure it? is it in kodi settings or in the TV settings?

7

I understand that CE22 involves a different kernel so needs a clean install. Is there a way to upgrade that keeps my addons, config and theme?

8

Yes, You can configure CEC - system - input - configure attached controllers - CEC

Ok thanks for all the replies. I’ll try leaving kodi on to see if this fixes the problem. Otherwise I can try CE22-no

Will leaving kodi on all the time waste much power though. I’m not sure what an odroid n2’s idle power usage is

1.6w standby up to 6.5w in use
