If your television is displaying a blue screen or no signal message and then turning off, your TV may be at an inactive input. Here's how you can get back to watching your TV:

1. Powering on your TV and press the INPUT button on the VIZIO remote control repeatedly until a picture re-appears.
2. If this does not work, try again but press the button slower this time.
