CEC works on RPI only LG do not support Power Off (Standby) in their CEC implementation. Power On working fine.

Hi.
Has anyone tried use IRDA connected to Raspberry for control TV - turn on, turn off?
I dont want to use the relay on the power cable, I heard that this is not the best for Tv. I dont know where connect relay inside TV, there is no normal standby button.

There is no power button, there is a small joystick. you have to move and press. I am thinking about controlling the power supply - relay, it works. Only when TV turning on, shows the LG start screen /input screen- OSD

Ok. I found the answer here:

“LG do not support Power Off (Standby) in their CEC implementation”
I use pir sensor and relay to turn off/on TV. Is there any other solution to turn off/on the screen but that the OSD does not show up?

Hi.
I searched the forum but I can not find the information why the command doest not work:
TV Off:
echo “standby 0” | cec-client -s -d 1

Tv on and scan working fine.
