Since this morning (I do not know if anyone else to play with the TV) but the screen is black and there is a message that pop up repeatedly: Online mode. The set-top device is online functionnality is available, OK.
When I press OK, nothing changes. It's freeze in the screen ... Yet some function on the remote control still works the power button and the setup.
I tried the power button on the decoder, nothing has changed ....
I read somewhere that I need to reboot... who can I do that?
