If you have been experiencing a black line on your Hisense TV, this post will show you likely reasons why and what you can do about it.
Why Is There a Black Line On My Hisense TV?
A black line on your Hisense TV shows a problem with your device. It could be related to a tab error, wrongfully fixed cables, or image resolution incompatibility. In short, the problem could arise from a poor connection or a processing issue.
An outdated firmware or a broken panel could also be why this black line is on the screen. The following are insights into each of these causes.
Hisense TV requires you to update the software occasionally. While this aspect is assumed to be automated, there are instances when you need to do it manually.
Suppose this firmware gets outdated for a significantly long time. In that case, expect the TV to have a strange horizontal or vertical line across the screen.
Usually, the most critical firmware are graphic drivers and system software. An outdated graphic driver will not process the latest high-resolution images you desire. It could also fail to stream or process any image at all.
Suppose your TV screen gets broken or damaged. In that case, it will be hard to process or transmit the images.
Ideally, a broken panel implies that the gate driver will have failed. However, it will be fair to mention that some cracks might not affect image transmission.
For instance, your TV will offer an excellent view if the outer screen is damaged. This screen is often used for protection.
However, breaking the inner layer means that the TV will start bleeding. In this case, LEDs will start affecting each other, causing the line on the device.
Obviously, it would be more likely that your TV is damaged if the black line started after you dropped the TV or did something similar. However, it could also be a result of things such as overheating.
Poor Cable Connections
Poor cable connections will often result in vertical lines on your Hisense TV. This improper connection makes it difficult to process images between the processing board and the panel.
Remember, this cable could be improperly fixed, faulty, or corroded.
Take the time to inspect the cables and ascertain their health. Corroded wires are likely to be expected in areas with extreme temperature swings.
You might also witness this cause in regions with high humidity. In such instances, remove the cables and clean them accordingly. You could also replace them with newer options.
Incompatible Image Resolution
Incompatible image resolution often happens when the image size is different from the actual TV resolution.
Whether the image is bigger or smaller than the resolution, expect a significant difference on the screen. The line could be either vertical or horizontal.
What Types of Black Lines Can I Get On My Hisense TV?
Your Hisense TV is susceptible to different black lines, including wavy, straight, vertical, and image-stacked lines. Each line represents something. Here is what each option indicates.
You could also refer to them as moving lines. These types of lines usually indicate a poor connection, whether from a signal or your cables.
These lines are stationary. They indicate a problem with the internal work of your TV. This internal issue could be anything, from firmware to system errors.
You will expect vertical lines if you have a poor connection. This problem could also arise if the cables are faulty or corroded.
Multiple Images on Stacks
You can also witness multiple images stacked on top of each other. This element is called ghosting.
It shows that various internal parts are not functioning accordingly in most cases. Yet, you could also experience it if there is a bad connection.
How to Fix a Black Line on a Hisense TV
Various steps go into fixing black lines on your Hisense TV, including cable changes, firmware updates, and screen replacement.
Understanding when to consider each option will cushion you against financial constraints in the long run. Notably, we look at a few insights into when and how these options suffice.

When fixing black lines on your Hisense TV, your cables are the biggest culprits. These cables need to be seated appropriately, ensuring that you get the connection you deserve.
Proper seating ensures that the image clarity is stable and high-quality. There will also be no need to worry about black lines on the screen.
Cable replacement is quite common in specific areas. High humidity and extreme temperatures in some regions often make your cables corrode much sooner. For this reason, inspect your wires from time to time.
One of the biggest causes of black lines on your Hisense screen is outdated firmware.
Investing in advanced and current software will cushion you from this problem. This solution requires you to keep the graphics drivers updated.
These updates will ensure there are no bugs or errors with the system. At the same time, you could consider updating the entire system, protecting your TV from unwanted security and image transmission issues.
Updating firmware is significantly straightforward. You’ll first need to launch the Smart Hub by pressing the Home button.
This step allows you to navigate to settings, where you will select support. Next, click on software updates and update your system. Follow the on-screen prompts to kickstart the process.

Suppose your firmware is updated, but the black line persists. In that case, it would be best to consider factory resetting your device.
That is because the source could be corrupted. Your graphic drive might also be compromised, meaning that this factory reset will ensure that the problem goes away.
You can reset your Hisense TV by following simple steps on your remote control. Usually, you will press the Home button and select Settings. Here, you will navigate to Reset via General.
Once you click reset, you will be prompted to enter the default pin, four zeros. Follow the on-screen prompts until the process is completed.
Consider a Picture Test
A picture test is a self-diagnostic process that allows the TV to identify the problem and find a suitable solution.
Its goal is to troubleshoot the black line-related problem and find an excellent solution. In most cases, this process ensures that you understand whether your Hisense TV is compatible with a specific image.
You can perform this process by clicking on Device Care under Support.
Clicking this tab allows the device to conduct a quick scan before you can select the Self Diagnosis button. Next, click on Picture Test and choose OK.
Replace the Screen
Sometimes, the black line on your screen indicates that the TV is damaged or broken. In such instances, you will need to replace the screen.
However, it would be best to procure it from a reputable Hisense dealer. A genuine Hisense screen will likely last long, giving you value for your money. You will also be sure of no compatibility issues.
Black lines are pretty standard on Hisense TVs. They denote specific issues, including connection problems and software updates.
The insights above ensure that you understand how to deal with each problem effectively.
