Turning on a Vizio TV without a remote can be done in a few simple steps. First, locate the power button on the back or side of the TV. It is usually a small, round button. Once you have found the power button, press and hold it for a few seconds. The TV should turn on.
If you do not have access to the power button, you can also turn on the TV using the Vizio SmartCast app. To do this, download the app to your smartphone or tablet and connect it to the same Wi-Fi network as your TV. Once the app is connected, you can use it to control your TV, including turning it on and off.
