With out turning on the T.V., Push the [Input] button on the remote control. The TV should turn on and activate the input menu, just continue to push [Input] until it is set on TV (or HDMI, etc.). this should solve your problem.

After several hours of frustration, I finally read somewhere that you need to be sure everything is turned on....I think that I must have hit a botton that turned one of the hook ups off. Finally after three days....

You may try holding down the INPUT button during startup or pressing it a few times quickly.
If that doesn't help you may consider

TV is probably in the RGB mode. Since no computer is hooked up to the set it detects "No Signal" and will then shut off within seconds. To resolve you will need to attach a computer (laptop is easiest if you have one) to the TV RGB input. Turn on your TV and it should show what is on your computer screen. Then go to the input button on your TV and scroll to the input for the cable signal, or TV if no cable being used, and all should be good.

How do I get my Sony universal remote to work with my Visio tv!


On your Visio TV remote control there will be a Source button or Input button. Press it & on your TV screen select HDMI 1 or HDMI 2. See the TV to see how the HDMI cable is connected from TV to Set Top Box. Now take the other remote control i.e. Sony Universal remote in your hand. Press mute & Select simultaneously. A blue light will blink twice, Immediately release the buttons & enter the code. You have to be extremely fast in doing this.
Following are few codes which you can try:
002, 000, 011, 080, 111, 006, 071, 128, 1904, 925, 0000, 0834, 0810, 1685, 1786, 1032, 1972.
Check the Visio TV manual for the make of your TV & model no & if code is printed. Then contact Visio TV manufacturer or retailer for the Visio TV code to enter & synchronize with the Sony Remote Control.

The tv had blue screen briefly showing "no signal" then turns off. ... and I am getting the same blue screen-no signal.


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.

I got this off the vizio website.

Sounds like you mabe be on the wrong source. Try hitting the input button on the side of the set to change inputs. Input channel up or down find tv hit input again. If on the wrong input you will only get a blue screen and message no signal that will apear for a few seconds.

Try selecting a different input, or checking the device which you are receiving the signal from. A blue screen typically indicates that there is no signal.
