Moving LibreElec Raspberry Pi 3 across diff TV sets. CEC need reset?

Hi. I am using LibreElec on RPi3, on a Sharp TV, with CEC enabled. It works fine, until I removed the Raspberry Pi to a different TV. This time, a Samsung TV with support of AnyNet. It’s not working. I also moved this unit to another Sharp TV with CEC functionality (Aquoslink), though this is a much current model, and CEC not working.

My question is, does it require reset, or reinstallation of LibreElec when you move the same Raspberry Pi from one TV brand/ model to another?

Thanks.
