CEC no longer working after plugging Raspberry Pi 3 on a different TV

Hi. I went on a trip, and brought my perfectly working Raspberry Pi 3 with Krypton with me. I connected it to a different brand TV, which didn't have CEC enabled. I had to remove it, and bring it back home. After coming back, my remote at home no longer works to control the RPi3. I've enabled, disabled CEC. Unplugged, the RPi3, and re-plugged it. It still is not working. Any chance no reinstallation needed?

Turns out, after rebooting the RPi3, I just had to power cycle my TV, and CEC is up and running again. Thanks
