Your TV is probably in RGB mode which means its looking for a computer signal. Plug a computer into your TV and then it will stay on. Then you can change it back to TV mode.

    Absolutely was the issue. Hooked up my laptop to the TV RGB input and bingo, laptop screen was on the TV. I then went to the input button and was now able to scroll to the input for the cable signal and all is good.

Pull the batteries out of the remote control and try turning the set on using the set buttons on the side. Our remote control was causing this problem without any buttons being touched.

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.

Just try to reset so picture will back to normal again, some LCD TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

2. Unplug any connected devices (DVD, Set-top boxes, etc...)

4. Plug the LCD TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the LCD TV is responding again.
6. Turn off the LCD TV and reconnect the devices.
7. Turn on the LCD TV.

Hope it may help you;

42 in lcd vizio "no signal"


if the TV have a no signal sign which means most of the important part is missing. Try checking your connections. The best way is to hook up a dvd player using AV input (the yellow, red and white). make sure that you turn the device on and whatever input you connected the device to is selected. if your TV is a P50HDM model, the TV will shut itself off after a short period without and input connected.
