HDMI-CEC and Samsung TV remote

Hi,

I use an old version of CoreElec (9.2.8), because my TV box has the Amalogic S912.
On the other hand, although everything was working correctly, navigation via the remote control of my Samsung TV, it no longer worked overnight, without understanding why.
HDMI-CEC is activated, via Anynet+.

Do you know how I can fix this problem ?

Disable and enavle back CEC on TV and find CE device again.

Thanks, I tried this solution, but without success

Try turning tv off at wall for a few minute’s. Samsung CEC is very unreliable and plays up for seamingly no reason.

Thank you so much !
Why hadn’t I thought of that before. Having turned off/unplugged the television, the control system via the remote control works again.
