Vizio TV Won't Turn On, but White Light Is On

If your Vizio TV won’t turn on, but the white light is on, it could indicate a few possible issues. Here are a few steps you can take to troubleshoot the problem:

  1. Check the power source: Make sure the TV is properly plugged into a working power outlet and that the power cord is securely connected to the TV.
  2. Check the remote: Ensure that the batteries in your TV remote are not dead and that it is working properly. Try turning on the TV manually by pressing the power button on the TV itself.
  3. Check for firmware updates: Ensure that the TV’s firmware is up to date by checking the Vizio website for any available updates.
  4. Perform a power cycle: Unplug the TV from the power source and wait for a minute before plugging it back in. This can help reset any internal components that may be causing the issue.
  5. Contact Vizio support: If the above steps do not resolve the issue, contact Vizio support for further assistance. They may be able to help you diagnose and fix the problem or provide information on how to get the TV repaired or replaced.

Remember, if your Vizio TV is still under warranty, contact Vizio support immediately to get assistance with the issue. Trying to repair the TV yourself may void the warranty and cause further damage to the TV.

  • Power supply to the TV

If you experience this issue, try the following fixes. 

Power Cycle the TV

  1. Long press the power button on the TV for about five seconds.
  2. Disconnect the power cord from the TV/power source.
  3. Plug in the power cord.
  4. Turn on the TV.

  2. Navigate to Systems and click OK on the remote.

Vizio TV Won’t Turn on No Light

If your Vizio TV won’t turn on and shows no light, the remote, power cable, or TV might have a problem. Therefore, check the remote and power cable or do a power cycle.

Power Cycle the TV

  1. Long press the power button on the TV for about five seconds.
  2. Disconnect the power cord from the TV/power source.
  3. Plug in the power cord.
  4. Turn on the TV.

Check the Remote

The remote may have a problem if you use it to power on the TV, and it fails. For instance, the remote batteries might be dead. If this is the case, replace the dead batteries with new ones, and you’ll be good to go. 

Also, check for any stuck buttons. One stuck button may affect all keys and may fail to power on the TV. 

Check the Power Cable

A loose or damaged power cable won’t supply power to your TV—which will eventually fail to turn on.

Ensure the power cord is connected to the power outlet and your Vizio TV. Also, ensure it fits well in the power outlet and the TV. Unplug the power cable and reconnect it. If the TV doesn’t still turn on, try connecting the power cable to a different power outlet.

However, if the power cable is faulty, you’ll have no option but to replace it with a new one. 

Vizio TV Won’t Turn On Unless I Unplug It

The standby power supply might be faulty if your Vizio TV doesn’t turn on unless you unplug it. The standby power supply unit supplies power to the TV components that need to be on. Therefore, when you press the power button, the essential components sense it and respond accordingly. 

If the standby power supply supplies insufficient power to power the rest of the TV, your TV won’t turn on. If this happens, the TV will display a flashing power indicator light that fades off. 

You’ll notice that it will turn on when you unplug the TV and plug it back. Press the power button or use the remote button to turn it on—the TV powers on because it doesn’t need power from the standby power supply unit. 

You’ll need to replace the entire power supply board for a permanent solution. Alternatively, you can repair it, but it will cost you more than replacing it. 

Vizio TV Not Turning On With Remote

If you try turning on your Vizio TV using the remote and it fails, the remote may have a problem. Try to check the remote for any damage and the remote batteries, and check to ensure nothing is blocking the remote’s infrared signal.

Replace the Batteries

If your remote batteries are old and dead, they won’t power on the TV. Therefore, replace them with new ones and press the power button to power your TV. 

Remove Obstacles that Could block IR Signals

Blockages on your remote can block IR signals trying to communicate with the TV—therefore failing to turn the TV on. The Vizio TV has an IR sensor that receives infrared beam signals from the remote. Obstructions between the TV and the remote may interfere with the signals. Thus, failing communication.

Obstructions affecting signal transmission may include furniture, walls, and other electronic signals like Bluetooth. Move to a different location if you notice an obstruction between the remote and the TV. 

Check the Remote for Any Damage

If your remote is damaged, it won’t power on the TV. Liquid damage is a common cause of remote problems.

You fix a remote not working by disassembling the remote to check the internal components for damage. You can implement a DIY project or consult a qualified technician. Alternatively, you can replace it with another remote of the same model.
