Re: Send on/off to the screen via IR

[rsl]

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.

Ok. I found the answer here:
https://github.com/Pulse-Eight/libcec/issues/363

“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?

Since you cannot put your tv into standby via CEC I guess you have to find a hardware way. You should analyze the button panel of your screen and see if you can simulate pressing the power button of your screen via relay/gpio

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

Are there any secret codes for LG TV…?
