Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
What you'll need to do is first confirm what input you should be on: look at the back of the tv and check carefully to see where the cord coming from your source device (cable/satellite box, etc) is plugged in, such as hdmi1, hdmi2, etc.
Then, take the VIZIO remote, press the INPUT button (source button) to bring up the input list.
It should show several options. Keep pressing input repeatedly, or use the up/down arrows and then the enter button, to select the corresponding input, such as hdmi1 for example.
If that doesn't work, please let me know what is connected and where, as well as the full model number of the tv.
