CEC settings on your TV can control many functions. One of those is the box turning on and off with the TV. If you would like to turn that feature off so that the Ti4 box stays on, follow the below instructions:
- Go to Settings on the Home Screen
- Click Advanced
- Click CEC Control
- Click on CEC Switch turn OFF that will turn the other ones OFF as well.
- Now click on One key power off and turn that ON.
That should fix any issues with the box turning on and off with the TV.
