LibreELEC on Rpi 3, Samsung TV not working. CEC adapter detected on startup

  • Hi. I have installed LibreELEC on Rpi 3. Upon turning on Raspyberry Pi 3, it says CEC adapter found or something. TV has Anynet enabled. When checking a list of devices on Anynet, it doesn't see RPi 3, neither does it responds to controls on the remote. I've tried another copy of newly installed LibreELEC, it's working. Same Rpi 3, with same LibreELEC installed, works on Sharp Aquos TV.

    Any ideas?
