Start by power cycling the Entone Set Top Box located by the television. Locate the little round black cable going to the electrical outlet or power bar, and unplug it. Allow it to sit for thirty seconds, and plug it back in. You should get an Entone logo on your screen.
Your television may be on the wrong input. Televisions have multiple ways of connecting devices to them, known as inputs, or sources. To switch between these inputs, use your televisions remote control, not the Entone remote, and locate a Source or Input button. When you press that button, you should see a list of available sources or inputs on the screen, try highlighting them and pressing OK, until you find the television feed. Usually it will be one of the HDMI inputs.
