- Wait for about 15 to 20 minutes)

The reason for doing this is to be sure that the output and input produced meets the TV’s demands power-wise.
2. Consider the wiring
You have tried using the “Power cycle” method to fix your TV’s horizontal lines, but the problem hasn’t gone away. What else can you try?
Check the wiring that connects the TV to your device (HDMI cable) or the TV power supply cable.
There is a chance the power cable, or, probably the HDMI cable is faulty, or the connection is loose. If any of these is the case, horizontal lines could appear on your TV screen.
So, try to remove and reconnect the HDMI and Power cables. And check if the connection is correct. If you fixed the cables properly, but the problem persists, chances are the cables (HDMI and Power cable) are faulty, or one of them is faulty.
A Handy Tip: To know whether the HDMI or power cable is faulty or not, use them to connect a different device. If the connection was successful, something else is responsible for the horizontal lines your TV displays.

If you have tried all the methods above but the TV keeps displaying horizontal lines, the software or firmware could be the culprit.
So, try to update the software and see if that help to fix the display problem your Vizio TV has.
