Hello,

I can not power off the TV from command line:

I am using firmware v4(2012-12-06) and LE 7.0.3 (Generic.x86_64).

When I power off the LE it powe off the TV, so it is working well but I can not power off from command line.

Regards.

You have to stop Kodi before you can use cec-client. Otherwise it's blocked. Alternatively you can use cec commands from within kodi, for instance python scripts or json.
