My Vizio Has a Blue Screen But Doesn't Shut Off 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.

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.

Since you didn't give the model number or connection type (wired Ethernet or Wi-Fi), I'll start with the Ethernet setup, and I'm assuming you have not previously had the TV connected to the Internet.

First, disconnect power to the TV and the router. Power up the router first, and wait for it to establish its connection to the modem. Then connect the TV and turn it on, then test the connection. If that doesn't work, proceed to the next step below.

Review the Owner's Manual section on setting up the Internet connection. Check your router setup and make sure the TV is using the correct method for making connections to it, and that the router is not blocking the TV as an unauthorized device. By default, home routers are set up to use DHCP to automatically give IP addresses to anything connected, but many models permit setting them to block everything except devices specifically given permission. It is also possible to set up the router to use manually assigned IP addresses instead of DHCP; this would mean you have to give the TV an IP address in the same net as the router (the first three numbers in the set are the same, but the last must be between 0 and 255 and not the same as any other connected device. If the router locks out everything except specifically permitted devices, you will need to log into the router and add the TV's MAC address to the list of permitted devices (the MAC address should be on a label on the back of the TV).

If your TV uses Wi-Fi to make the Internet connection, first verify that you have adequate signal strength at the back of the TV (use a laptop computer or other device with a signal strength indicator if the TV itself does not display it in the Wi-Fi setup menu). Next, verify that the TV is using the same security protocol as the router, and that the password is correct. (Note: if you have a wireless router, it's always a good idea to make sure security is on and is not using the factory default password. This prevents freeloaders from stealing bandwidth and slowing down your connection, hacking your devices, or using your Internet connection for other ******* activity.)

try reseting the software of the TV or try connecting a different HDMI cable to the device you are using. If it works, then something with the device you are using is faulty and you might need to repair it.

Check this first:

• Connect your Amazon Fire TV device to one of these network or router types:
  • Open, WEP, WPA-PSK, and WPA2-PSK encrypted networks
  • B, G, and N routers on 2.4Ghz
  • A and N routers on 5Ghz
  • Hidden networks
• Enable wireless connectivity on your Amazon Fire TV device. From the Home screen, select Settings > System > Wi-Fi.
• Make sure you know your network password (if required). If you see a lock icon, a network password is required. This password is not your Amazon account password.
• Make sure your Internet connection is not down. Restart your router and modem to solve most Wi-Fi network issues.
• Do not place your wireless router or Amazon Fire TV device in a cabinet, as it impacts your Wi-Fi signal strength.

Also, try this for Fire TV Stick:

• Use the included HDMI extender to optimize the location of your Fire TV Stick. The HDMI extender can improve your wireless connectivity by positioning your Fire TV Stick further from the TV.
• Plug the power cord into the included power adapter and then into a wall outlet to ensure the device receives enough power for optimal performance.

Still having trouble?

• Restart your Amazon Fire TV device. Disconnect the power cord from your Amazon Fire TV device for three seconds, and then plug the power cord back in.

Tip: You can also restart your Amazon Fire TV device with your remote. Press and hold the Select button and the Play button at the same time until the Amazon Fire TV device restarts (about five seconds). Or go to Settings > System > Restart.

Connect the input device to some other TV and check. Look for: child lock, selective mute button, basic TV volume too low etc.

Hello
First make sure that the "Mute" function is OFF. If it is set to "ON", no volume will be there.

Your TV has a volume lock function included [Global Volume Lock].

The remote comes preset to allow independent volume control of each selected device (Global

Volume Unlock). However, you may change the Volume Lock setting to Global Volume Lock so that

one device's volume will control volume in all other modes. After that, you can perform Individual

Volume Unlock on a selected device to set its volume control for independent operation or Global
Volume Unlock to remove all volume locking.
Locking Volume Control to One Mode (Global Volume Lock)
[1] Press and hold SET UP until the red LED blinks twice; then release.

[2] Enter 9-9-3 and then press the mode key for the device you want to control volume (for

example,TV). The LED blinks twice. Now when you press VOL+, VOL-, or Mute, the selected
device (for example, TV) will control the volume regardless of the current mode.
Unlocking All Volume Control (Restoring Global Unlock)
[1] Press and hold SET UP until the red LED blinks twice; then release.

[2] Enter 9-9-3 and then press VOL+. The LED blinks four times.
Volume is now independently controlled for all programmed devices.
Unlocking a Single Device's Volume Control
[1] Press a device key (TV, VCR/DVD, CBL/ SAT, or AUX).
[2] Press and hold SET UP until the red LED blinks twice; then release.

[3] Enter 9-9-3 and then press VOL-. The LED blinks four times. Volume is now
independently controlled for the selected devices.
OK

I understand that your TV is turning ON but you're not bale to view the videos on the TV screen. If the TV is connected to a wall outlet through a Surge protector please disconnect the connection through the Surge protector and try connecting the TV to a working wall outlet and check if that helps. Please check the connection between the TV and the connected device. Please try using a different device and check if that helps. This is to check whether the issue is with the TV or the connected device. Please try to explain the issue as much as you can next time. What are the video sources connected to the TV? Does this issue occur with the TV when connected to other devices? How did you connect the videos sources to the TV? Which connection are you using to connect the devices to the TV? You TV doesn't support 1080p resolution, so please check whether the connected device is giving output in 1080p resolution. If the issue still persists service of the TV is recommended.
