I have a Raspberry Pi3 connected to a LG 42LM6200 TV thru HDMI.
On the last version of Libreelec with Kodi 16 the CEC function correctly
With latest version (8.0.0) CEC is very strange.
1. While watching broardcast TV the CEC will switch to the Pi by its self
2. While switched to the Pi but with no activity the screen saver tries to
operate but come straight back to life again as thought there is constant activity
happening somewhere maybe from the CEC
I have tried the fix above even using the two files from version 7.0.3
but no fix
Any help would be appreciated

Try System-Input-Peripherals (or something like that)-CEC. There are settings for wake/up etc related to CEC devices (TV/Rpi/Receiver) actions (switch chanell, power on/off).
