Finding the cause of your Vizio's problems can involve trial and error.
Troubleshooting your Vizio TV requires that you first identify the source of the problem. A blue screen on your Vizio TV can indicate that you are experiencing a problem with the video input on your TV, while the failure to turn off may indicate that there is a problem with overcharged internal memory or your power capacitors in your TV.
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.
