Apple TV is not turning off tv

After recent firmware upgrade Apple TV is unable to turn off my Sony Bravia XBR-65X850E model tv. I’m not really sure if the reason/cause was Sony firmware upgrade or Apple! As I have auto update enabled on both devices. Can someone please help me to fix this issue?

I have tried resetting both devices and they are on latest firmware also tried the basic troubleshooting steps posted online with no luck!
