Dear, I have a OSMC RPi 3B+, the tv remote control is not working for to manage the raspberry or to turn it on or off. I see in Menu setting of my Samsung Tv that Anynet+ (HDMI-CEC) is active.
I see on OSMC Setting the icon of remote control TV, in particular I see the remote control of Samsung TV, the image is the same of mine.
Your title says HDMI CEC Samsung TV not working! Is none of the keys working or just the power on/off not working?
This would not be possible. You only could use it to put the Raspberry into standby but even for that you would need to remap something else than the power button.
CEC has nothing to do with the “remote” section of MyOSMC.
CEC doesn’t need any configuration on OSMC (unless you disabled it).
CEC section is under Settings - System - Input
Two cable hdmi in the picture. The first ok (remote control TV working properly), the second not working with remote control. I don’t understand the difference.
