Finding the cause of your Vizio's problems can involve trial and error.

Check Your Connections The connections leading to and from your Vizio TV may be responsible for your Vizio TV having a blue screen and failing to power down. Tighten the coaxial connections to your TV and firmly press in any HDMI, component or composite video cables connecting to your TV, then check the signal on your TV to see if the blue screen problem resolves itself.

Discharge Your TV's Memory Overcharged internal memory can lock up your Vizio TV and prevent it from changing channels or turning off. To discharge your TV, unplug your TV and press and hold the "Power" button for 30 seconds. Plug the TV back into the electrical outlet after 30 seconds and check to see if the problem persists.
Change Input
The input source connected to your TV may be malfunctioning and preventing your Vizio TV from powering off. The "Input" button on your remote will allow you to select a new input source. Cycle through input sources until you find one that displays an image on your screen and power the TV off. If this method works, you may need to replace the input source preventing your TV from turning on.

Power-Cycle Your Equipment Power-cycling your equipment can solve errors created by devices or with your TV's power supply. To power-cycle your equipment, unplug your TV from the electrical outlet along with any devices connected to your TV. Plug your TV back in and turn it on. Plug in each device, one at a time, and notice if your TV displays a blue screen or has trouble turning off. Repeat this process for each device connected to your TV and replace any devices causing problems with your TV.

On some TV's the screen will go blue if there is not a strong, solid video signal present. This is to prevent the showing of very snowy or all snow channels, or garbled, mixed-up external video signals. This is normal. On some VCR's the video signal changes when the FF or REW search feature is used, and this could trigger the TV to go to blue screen. The only way around this if you can enter the TV's menu and turn off the blue screen feature.
