I have a Samsung Smart TV and the Nvidia shield (redundant, I know) and through hdmi-cec, I can turn on/off the shield/TV with one another.

If my TV and shield is off and I press a button the nvidia shield remote, my TV turns on and switches to the right input. After this, the remote refuses to respond to any more button presses. I would have to pull the power cable out and plug it back in for the remote to work.

Does anyone know why this is happening? Is there a better way to do this?
