Facing TV Problems? Ask a TV Technician.
Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
What all source types have you tried that you can confirm are affected?
Can you try the following:
1. Reseat all cable and connections to the television from your devices. Physically remove the cables from both the television and the device and reconnect them.2. Check your Advanced Video settings in the Vizio TV menu some of our Vizio televisions will allow you to adjust the following settings under the Advanced Video settings:Ambient LightingBacklight ControlAdvanced Adaptive LumaIf you have any of these options available please turn all of them off to see if this resolves the display flickering.If the above steps have not resolved the issue please take the following steps in the order presented:1- Power off TV2- Unplug TV from outlet3- Press and hold in the power button on the TV for 30 seconds (while it is unplugged from the wall)4- Release the power button5- Plug in the TV into a different outlet6- Power the TV back onThere is also a factory reset option in your menu under the SETUP section. It will say either "reset all settings" or "system reset". Try it and let me know if it makes any difference?
