A malfunctioning lighting could be the leading cause of a flickering screen. However, you cannot rule out a power issue either.

However, if only the television is flickering, it could be a faulty outlet.

Additionally, ensure that you are using a more recent version of HDMI cable.

Vizio suggests using versions 2.0 and 2.1.

Vizio televisions have at least four HDMI ports. Attempt to connect your external device to another of these ports. Additionally, ensure that you have the correct input setting on your television.

In rare circumstances, the screen flickering is not caused by the television. Alternatively, the wires and ports.

Instead, an external device is responsible.

Therefore, a simple approach to determine this is to disconnect all of your TV’s external devices.

Then, execute a power cycle on the television.

Did the flashing cease?

If this is the case, the problem lies with the connected device.

Therefore, regardless of whether the gadget is a gaming console or a media player…

Check any settings that could cause image problems. Additionally, confirm that it is undamaged and flawless.

Additionally, you may quickly reset it by disconnecting it from the wall socket.
