Anyone who used lircd.conf can power on C2, Could you upload your lircd.conf file?

THANKS FOR HELP.

IR Power on commands are Hardcoded into U-Boot. As such Power On commands are only coded for the C1/C2 IR remote or Harmony remotes programmed as C1/C2 remotes.

This cannot be changed.

I suggest you use HDMI-CEC control instead to get your TV to power OFF / ON the C2.

Play with settings....
Kodi Settings > System > Input Devices > Peripherals > CEC Adapter > .....
