Remedies to Fix Horizontal Lines on Hisense TV Screen
Although you are not aware of the reasons behind the horizontal line, follow the fixes sequentially in the guide below and get rid of the issue on your TV.
Check the Power Source
A power supply is a major factor in running a smart TV without interruptions. Any problem with the power supply causes voltage fluctuations, which create horizontal lines on the TV screen.
The reason for a voltage fluctuation is a faulty surge protector. So, make sure to remove the surge protectors from the power socket and connect the TV’s power cable directly to the wall socket. If the power source is the reason behind horizontal lines, this will definitely fix the issue on your TV.
Power Cycle the Hisense TV
Restarting the Hisense TV will help you remove the horizontal lines if they are caused by a temporary issue. This is one of the basic methods that need to be performed when your Hisense TV is functioning abnormally. To power cycle your TV, simply unplug the power cables from the socket and rest the TV for a few minutes. Once you drain out the excess power, you must re-plug the power cables and power on your Hisense Smart TV.
If the issue is simple, the horizontal lines on your Hisense TV screen will disappear. Otherwise, proceed to the next troubleshooting method.
Update the Hisense TV Firmware
Sometimes, outdated firmware can cause horizontal lines on your Hisense TV screen. This is because of bugs or glitches in the older firmware. Therefore, you must update your Hisense TV to the latest version to ensure it has bug fixes and new improvements. After updating, check if you can see uneven lines on the TV screen. If so, the problem may be with the connected cable. Try the next solution to rectify the issue.
Inspect the HDMI Cables
A poorly seated HDMI cable will also display the horizontal lines on a TV screen. This issue is similar to a vertical line on your Hisense TV. The horizontal line issue on the TV may be due to loose, damaged, or torn HDMI cables.
It is also guaranteed that a wrongly impaired HDMI cable will also be a cause of this issue. You can overcome it by changing the damaged cables to a new one and switching the cables to a different HDMI port.
Check the Hisense TV Inputs
If you have connected any external cables to your Hisense TV input, ensure that the port is in good condition and the cables are connected firmly to the input. Any loose connections in the cable will cause the Hisense TV to flicker and may display the horizontal lines on the TV. So, remove the connected cables and make sure to plug them into the correct input port.
Note: Ensure to change your Hisense TV input source if you have connected to any external device.
Inspect for Hardware Damage
Moving to the internal parts, any damage to the T-Con board will also lead to screen problems on the TV. A Timing Control Board is a small PCB board that drives your TV’s panel to translate the signals into pictures on the screen. So, if this board is damaged, it needs to be replaced immediately to avoid screen problems like horizontal lines.
Every Hisense TV is incorporated with ribbon cables that are widely used for internal peripheral connections. If these ribbon cables are connected loosely to the TV, the horizontal lines may appear on the screen. Sometimes, you can also see vertical lines on the TV screen.
To fix this issue, you need to carefully rearrange the ribbon cables properly to its original position. If you are not aware of the electronic components, better contact the Hisense support team or visit a nearby TV shop to repair the issue.
