Let’s get started!

What causes horizontal lines in Hisense Smart TV?

Hisense’s Smart TVs are renowned for their budget-friendly pricing. However, some users have been complaining about horizontal lines appearing on their screens.

So what could be causing this issue?

There are several possible reasons for the appearance of horizontal lines on a Hisense Smart TV:

1. Input Cable Connectivity Problem

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 Outdated Software Version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. TV Panel Defect

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.
