Raspberry Pi 4 Libreelec HDMI CEC not working
#1
it worked a few weeks without a Problem now suddenly it did not work anymore.
Reinstalled Libreelec not working. very unresponsive if it works. I do not have any idea why?
Pi 2 and 3 normal HDMI no Problem. PS4 No Problem but my Samsung TV 2012 Modell did not find the Pi 4 anymore.
I checked two Cables. Both the same type on wich it worked before. checked booth HDMI Plugges on the Pi. Nope.
Checked 2 differentiations Micro HDMI Adapters. 
I ordered a new cableComes maybe tomorrow but how? Why? Whats wrong? I did not get it and I´m very sad.

CEC issues are often resolved by powering off (unplug from mains for a few minutes) the TV and any other CEC devices.
When connecting up again start just by connecting TV and Pi through HDMI (without other HDMI devices connected initially).

You may need to check TV user guide for how to enable CEC and choose the CEC device (most TV's do this automatically, but there is a lot of differences in implementation).

If it doesn't work try a different hdmi cable (ideally the one that worked before). Cheap hdmi cables may not have all lines wires up.

I checked all that no luck.
now I do need to change the pi and maybe this will resolve the problem. I do report back.
