Is CEC enabled on your C1? If it is you should be able to navigate Kodi with the LG remote. Without CEC I don’t think the Vero has the ability to turn that TV off. I have actually tried with a Vero and that same TV and the other methods of cutting off the display only get a blank display, not the ‘no input so here is some framed artwork’ screen that can trigger the TV to turn off.
