Why Does My Vizio TV Keep Turning On And Off : How to Reset your VIZIO Smart TV

Vizio TVs have an auto-off function intended as a power-saving feature. By default, the TV will turn itself off if it detects no signal for ten minutes (like when your Netflix show stops streaming).


You can disable the Auto Power Off feature from the sleep timer menu. Use the up/down arrows on your remote to highlight the Auto Power Off feature then click OK. This will take you to the Auto Power Off menu. Highlight Off and click OK.

Turn it back on… put the remote in a black bag in a drawer and see if it keeps happening… if so, pull the curtains tightly closed and see if it’ll stay on then. Finally put everything that could emit an IR or ultrasonic signal in a well insulated container in a different room with the door shut. And, if possible, disconnect it from the network, if it’s a Smart TV.

This will preclude the possibility of interference either from a malfunctioning remote, phone, or local wag who’s able to point their remote through your window, or some rogue network signal.

After which, look in the menus to see if there’s a particular shutdown time set, or an “eco” timer that will turn the set off a certain amount of time after the last remote control command (at which point it assumes you’ve either fallen asleep or left the room). These can be set surprisingly short sometimes.

If none of that works, make sure the power lead is firmly and properly plugged in all the way from the main outlet to the set (you’d be surprised how often this can cause trouble, they do slowly work their way loose).

My device won’t power on / will not turn on / no power

If your device won’t power on or powers on by itself, try the following steps:

  1. Press the power button on the device. As you press the button, look at the power indicator light. Does the power light turn on at all? Power indicator lights may appear as below.
Example of Orange power indicator light Example of White Power indicator light Example of single light power indicator
Changes from Amber to White Changes from a dim light to a bright light. Turns on and then slowly fades.
  • If the power indicator flashes from orange to white wait about two minutes. If the power indicator light is still flashing then there is a problem with your TV. 
  • If the power light comes on, the device is powering on. If this is the case, you may be having a picture issue.
  • Newer VIZIO TV’s that have a white LED power indicator light are designed so that the indicator light fades out when the TV powers on. If the light doesn’t fade off and just turns off then there is a problem with your TV. 
  1. If the power light is not lighting up at all, reseat the power cable in the back of the device and where it plugs into the wall.
  • To reseat the cable, unplug the power cord from the device, and plug it back in. Make sure it is securely and tightly connected to the device. Do the same in the wall outlet. If the power cord is connected to a power strip or surge protector please verify that the surge protector/power strip is turned on.
  1. If the device still isn’t powering on, try plugging another device into the outlet to make sure it’s getting power.
    • If another device (like a lamp or cellphone charger) is getting power from the outlet, the outlet is working, your device is experiencing an issue.
