Sony TV Horizontal Lines on Screen: Reasons + Easy Fix

SONY TVs are known for their display color quality. But, several times I saw Sony TV horizontal lines on the screen issue which is annoying.

If you have a Sony TV and notice horizontal lines on the screen, there are fixes for it.

These horizontal lines do not match the other display pixels on the led tv screen but appear as green lines or black lines on the Sony TV screen.

Let’s get started!

Causes of Horizontal lines in Sony Smart TV

1. Input Cable Connection Issue

One possibility is that the issue is caused by a loose or damaged HDMI cable.

The input cable connection issue is a common problem that can be easily resolved by checking the input HDMI cable connection.

To check the input cable connection, check that the input cable is connected to the correct input port. 

If the issue still happens, try to reconnect the input cable to the correct input HDMI port. If the issue still happens, try another input port. 

If the issue is still happening, try to connect another device to the input port to rule out the input port as the cause of the issue. If the issue is still happening, service may be required.

2. Outdated Bravia TV Firmware Version

Another possibility is that there is an issue with the TV’s software. If there is an issue with the software, it can cause horizontal lines 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. 

If you’re experiencing horizontal lines or other image problems, a software update may help you solve the problem. 

3. Video Source Problem

Issues with the source of the video signal could contribute to horizontal lines on the screen. Ensure that the device connected to the TV is functioning correctly and provides a stable signal.

4. Issue on Sony TV Panel

Another common cause is a problem with the TV panel. 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 maybe is just dirty or dusty. Still, you need the help of a technician as you won’t be able to peek into the panel yourself and it is also not recommended to do it on your own.

When a horizontal line appears on the screen of your Sony TV, it can be either a problem with your TV, or it can be a problem with your cable or satellite box.

If the horizontal lines are not caused by the cable or satellite box, then the problem is with your Sony TV.

A black horizontal line is not always a panel issue. Typically, this can be caused by a bad pixel or a bad connection on the screen.
