Causes for Horizontal Lines on Vizio TV

Horizontal lines on a Vizio Smart TV can be caused by several factors, including input cable connectivity problems, HDMI cable issues, outdated firmware versions, panel issues, and other internal hardware issues.

Here are the reasons in details:

Input Cable Connectivity Problem

One of the most common causes of horizontal lines on a Vizio Smart TV is a loose or damaged HDMI cable. This issue can be easily resolved by checking the input HDMI cable connection.

To check the input cable connection, ensure that the input cable is connected to the correct input port. If the issue still happens, try reconnecting the input cable to the correct input HDMI port.

If the issue persists, try another input port. If the issue is still happening, you may need to service your TV.

HDMI Cable Issue

Another possible reason for horizontal lines on a Vizio Smart TV is a faulty HDMI cable. If the HDMI cable is damaged or not functioning correctly, it can cause horizontal lines to appear on the screen.

To resolve this issue, try using a different HDMI cable to connect your devices to the TV.

Outdated Vizio TV Firmware Version

An outdated firmware version can also cause horizontal lines to appear on your Vizio Smart TV. If there is an issue with the software, it can cause horizontal lines or other image problems to appear on the screen.

Updating your TV’s firmware version should be done when there is a software update available. A software update can include several fixes and improvements, which will improve your TV’s performance.

Vizio TV Panel Issue

A problem with the TV panel is another common cause of horizontal lines on a Vizio Smart TV. If there is a problem with the hardware, it can also cause horizontal lines to appear on the screen.

A panel issue is related to the screen of your TV. If your screen has suffered physical damage, you should take it to a technician for repair. If you have a new TV, the screen may just be dirty or dusty.

In this case, you should seek the help of a technician as you won’t be able to peek into the panel yourself, and it is not recommended to do it on your own.

Other Internal Hardware Issues

Other internal hardware issues, such as a faulty T-Con board, power supply, or processing unit, can also cause horizontal lines to appear on the screen.

If you suspect that your TV has an internal hardware issue, it is best to seek the help of a technician to diagnose and repair the issue.

Verify the Lines are Permanent or Moving on Vizio TV

Before attempting to fix the issue, you should determine whether the lines are permanent or moving.

If the lines are permanent, it’s a hardware problem, and you should contact Vizio or take your set to a TV repair center.

Perform Picture Test Switching Input Source

Before you start to fix Vizio TV Horizontal Lines on Screen, you will want to run a picture test.

If required, you can also remove the Vizio TV’s back panel and reinsert the T-Con ribbon, cleaning its contacts with compressed air.

Update Your Vizio TV Firmware

If you are facing the issue of horizontal lines on your Vizio TV screen, you need to update the firmware via their OTA updates to the latest version. The first thing you want to do is to check if your Vizio TV has the latest software updates.
