My wife has mentioned an issue with Kodi responding on TV remote signals but screen being black and finally I was able to reproduce it this morning. The symptoms are:
on remote press TV changes LED from red to green to indicate waking up from power-save mode. Shortly after you get a Kodi window, however rarely you only get a blank screen
Kodi intercepting the keys, audio working fine (I was able to navigate menus using VNC)
TV is “seeing” the signal on HDMI
systemctl restart kodi did not resolve the issue
replugging HDMI into another port on the TV did not help either
What finally resolved this situation was a reboot of Odroid. I could probably make a shortcut for that but perhaps someone has a better idea how to debug and fix this?
I don’t know if this is applicable on CE, but I remember from the openelec days, that adding the following line to config.txt could possibly solve display related problems, especially concerning HDMI signals:
hdmi_force_hotplug=1
I had to use the line because my Raspberry Pi booted faster than my TV and didn’t receive a signal from the TV in time, so turned a black screen on me.
I SSH’d into my CE, en found no config.txt but config.ini in /flash folder…
As I am having the same problem after an hour or so idle time, I will make this change to config.ini and test it out.
After several tests with different idle time periods, and AVR/TV combo switched on of off (or in powersave mode), it looks like this extra line in config.ini solves the mentioned issue.
At least, in my current situation.
I will keep the change in config.ini, and will report any developments in this topic…
Update August 10: After 10 more tests, I can confirm that the extra line in config.ini solves the topic starter’s issue.
