If not, turn on the Hisense TV again. Place your hand in the corner area where the horizontal line goes over the screen and lightly squeeze.

Solution

Check if the horizontal line is still visible on-screen. If yes, then jump into the following method.

Faulty TV Connection/Components

If your Hisense TV has glitching horizontal lines all over the screen, then it is most likely because of connection errors. Either it is not done in the proper way, or the components involved have turned defective.

Solution

Go near your power outlet and see if your Hisense TV’s power cord is connected properly. If it is halfway out, unplug it and insert it fully into the outlet. Then, turn on your TV, and it will most likely return to normal. Suppose it has not changed and you are not able to see anything but cluster & grainy horizontal lines, unplug the TV again. Now, carefully check all over the TV cable. There should be some insulation damage or heat burns in it for sure. Also, check the pins to see whether any of them are shaking or broken.

Otherwise, inspect the power outlet and make sure it is not damaged. Using a tester, check whether all its slots are currently transferring current. If there’s any damage/discrepancy on these components, repair them with professional assistance. After a repair, your Hisense TV will not show any horizontal lines.

Problems in Input Source/Power Supply

The problem of horizontal lines on the Hisense TV screen will occur because of damage or any sort of issues with the input to which your device is connected to Hisense TV. This is one of the major unnoticed factors. With that, you should also check how stable the power supply of your home is since it will also favor this issue.

Solution

First of all, check whether all the electric devices in your home are working properly and receiving ample power. If there are power fluctuations and inconsistency, never think of managing to run your Hisense TV, ignoring the pair or more screen horizontal lines. Immediately stop using the TV and call an electrician. Sort out the power supply issues and proceed to use your TV after this without lines on the screen.

Suppose the other devices are functioning normally, unplug the streaming device from the connected input port. As a try, connect the device to another port and access it by changing the input on Hisense TV. If everything is normal now, the former HDMI port is faulty. Check whether it’s damaged to repair or resolve issues and reach out to the Hisense TV support team or service center. Until then, you shall use the device on Hisense TV by connecting to the alternate port. In some cases, your TV will have problems in receiving proper voltage. You should service the TV to rectify this.

Old/problematic firmware

If there is just a single horizontal line passing through your Hisense TV screen and it is not going off after trying all the above troubleshooting methods, then turn your attention towards the firmware. An outdated or corrupted firmware is capable of attracting miscellaneous agents that cause horizontal lines and flickering screen on Hisense TV.

Solution

Since your Hisense TV is accessible despite the single line in the center, head to the Settings option. Check the firmware version and see if it is in the latest version. If it is outdated, update your Hisense TV now, and the horizontal line will vanish after a restart.

Some of the users report that their Hisense TV got lines on the screen after the firmware update. In this case, you can factory reset your Hisense TV. There is a high chance that resetting will fix the corrupted software and clear the horizontal/vertical lines appearing on Hisense TV. If that doesn’t help, wait till Hisense releases a new firmware update to rectify this error.

Interference With Other Devices

In some cases, external factors come into play in the horizontal lines appearance of Hisense TV. That is, signals coming from other electronic devices interfere with those of Hisense TV.

Solution

See whether you have placed computers, microwave ovens, satellite phones, or another TV near your Hisense TV. There are some chances for their signals to mix with your Hisense TV signal, due to which you will have flickering horizontal lines on the screen, or the remote will stop working. If anything is there, turn it off or change it to another location. If you are lucky, this might fetch you a favorable outcome.

Wrong Display Resolution

While watching a particular movie or series, you might have to change the resolution that suits it. Keep in mind that it may not be suitable for your Hisense TV as a whole. If there is a mismatch, your Hisense TV will display horizontal white lines on some rare occasions.

Solution

To fix the resolution mismatch, go to the Settings menu and access your Hisense TV picture settings. Change to the alternate resolution from the current one. If necessary, you can also change the display ratio in an attempt to rectify the issue. If there aren’t technical reasons or interventions, the horizontal lines of Hisense TV will surely disappear after this.
