47inch tv. Turn on manually with on/off sensor button. Once it turns on (the screen is blue and says no signal) - press the "source" sensor button three times in a row. The input menu magically appears. Press the source button as many times as it takes to get to the input which brings back the tv. In my case, TV.

Vizio light is on on the front of tv, but when you turn it on it says no signal and turns off. VX37L

Your TV may be in RGB mode. Immediately after turning your TV on, press the TV button on the 'input' section of the remote. Hopefully that works for you. Your TV is designed to turn itself of in RGB (monitor) mode if no signal is present.

While trying to change channels, my t.v. displayed ''no signal'' and then shut itself off. Now, when I turn it on, it says no signal and turns itself off after a few seconds.

Turn the television on and as soon as the screen turns on repeatily press the input button or change the input to whatever input you are using from a source device. As long as you change it to anything other than RGB.

Your television is essentially a big computer monitor with multiple inputs and a tuner. When using your computer and shutting it down the monitor will go in a power save mode. You don't need to shut off your monitor due to this power saving mode. When you power up your computer your monitor automatically turn on.

With the VIZIO and the RGB (computer) input the television will act just like a computer monitor. When you have a computer connected it will power down automatically when you shut off your computer. When you turn your computer on the VIZIO will automatically come out of standby mode. This is through RGB only.

This is normal operation for the VIZIO but can see confusing when nothing is connected to the RGB input. If you change your television input to RGB it will sense no signal on the input and will go into standby mode after about 5 - 10 seconds. If you were to send a signal to the television through RGB it would automatically kick on.

Just hold down the input button on the right side of the tv. This is the bottom one. So,
With the tv off,
press and hold the bottom button (input)
when the tv turns on, and you see the input menu
release and press the button to put the tv into a mode that works!

T.v. will not stay on

Power on your TV and press the INPUT button on the side of the TV repeatedly and rapidly until you can change it to a different input, such as AV.

If this does not work. Try this: With the TV off, press and hold the input button on the side of the TV for about 5 seconds. The TV should power on and the input list will appear. Let me know if either of these work.
