I have a LG OLED55B7V and I cant get CEC to work. I did a manual "bisect" and the latest version i got CEC working with was #323.
The builds that didn't work also had a grayed out Peripherals under settings->system->input, and only joystick was available under the driver menu when that was present

Can you test the official release LibreELEC 8.2.2 and see if that is better/worse/same. Also try the latest test build with a "clean" Kodi, ie. rename your .kodi folder to .kodi.bak, so that you start with default settings (in case a setting is corrupted). Try powering off the TV at the mains for 5 seconds in case the TV is the problem.

You're the only person reporting CEC not working with LG which makes me think this is more likely to be an issue with your environment/settings/TV.

If nothing works then enable debug logging, enable CEC component debugging, reboot the RPi then upload your kodi log. 

 CEC works for me on Libreelec 8.2.2 I tested it the first thing i did yesterday when I noticed that #1228 wasn't working. .kodi is only 3 days old, I had problems when i first updated to alpha builds so i did a fresh install, but i will try it anyway and upload log
