I have elaborated on the factors causing vertical lines on the Hisense TV screen in the forthcoming headings, along with the necessary solutions for rectification.
Screen Damage
When you see lines on Hisense TV screen, be it vertical or horizontal, damage is the reason most of the time. If you encounter this issue while you set up your new Hisense TV that you’ve just unpacked, then the damage has occurred because of careless transportation. Otherwise, you would have mishandled your TV and made it yourself.
Solution
If the screen of your brand-new TV is damaged, contact the showroom from which you bought it to report. If you have bought it online, raise a complaint. They’ll send their authorities to inspect the TV and find out the cause of the damage. If the mistake is from their side, they’ll mostly provide you with another new TV set as a replacement. Otherwise, they’ll repair or replace your Hisense TV screen, barring all the charges.
Suppose it is you who has accidentally caused the damage, you have to pay for your Hisense TV screen replacement cost. It varies for each model, region, and display type. On average, you’ll have to spend $100 to $1500, depending on the intensity of the damage. You can better claim a warranty for your Hisense TV screen repair or replacement to do it for free or at a comparatively lower charge.
It is cent percent sure you won’t have vertical lines on a new or Hisense TV screen in proper condition.
Improper Hisense TV Connection
Luckily, if your Hisense TV screen is fine, then there is a high chance that your TV is having just minor issues. The primary one will be that your Hisense TV is not connected properly because a loose connection will bring up the Hisense TV vertical lines on the screen.
Solution
Navigate to the rear side of your Hisense TV unit. Check if the power cord is affixed well with the power socket. It might have come out slightly while you adjusted the TV position. So, insert the TV cord properly into the socket and check if the vertical lines have disappeared.
Suppose the socket is not getting attached to the TV cord, there is a hindrance due to blockage or tiny dust particles. So, clean the power socket and make the connection. If it doesn’t work, connect a junction box to the socket and connect your TV to it to avoid a further loose connection and the appearance of vertical lines on the Hisense TV screen.
TV Cable/Socket Damages
If there is no loose connection, then your TV cable or socket should be impaired for displaying vertical lines on the TV screen. This should be immediately rectified because it will spoil your viewing experience until then. In some worst scenarios, you might experience an electric shock when you touch the cord or turn on your Hisense TV’s socket switch.
Solution
First of all, turn off your Hisense TV. For safety, use woody or plastic objects. Unplug the TV and examine the power cord carefully. Look for abrasion breaks, heat damage, or kirks. Most importantly, pay attention to the pins and make sure they are not shaky or broken. When you notice any such damages, repair or change the power cord completely with the help of repairmen in a professional TV service station.
Suppose there is no damage to the TV wire, then you have to look into the power socket. Ensure it is not damaged and check if it is supplying power properly using a tester. If there is any discrepancy, you should contact a trained electrician and get it repaired. Until then, you can access your TV with the help of an alternate power socket, where you won’t have vertical lines running on-screen.
Short-lived Issues on Hisense TV
Besides the external factors, some problematic bugs and cache present on your Hisense TV will start reacting, and they’ll display vertical lines on its screen. These factors just stay momentary and don’t require extreme troubleshooting methods.
Solution
Before deciding whether your TV screen is affected by any of the following factors and trying their corresponding troubleshooting methods, once properly restart your Hisense TV.
If it turns down unsuccessfully, undo your TV connection. Leave it untouched for about 30 minutes and power cycle. Then, make back the connection. If you are fortunate enough, your Hisense TV will be free from vertical lines.
Unstable Power Distribution
When you still have vertical lines on your Hisense TV screen after checking for all possible errors and even shifting it to a new location, then the problem is with the power supply of your whole household. If you continue to watch your TV in such a surrounding, managing those vertical lines, then you’ll have to say goodbye to it because of the permanent damage it is going to attract.
Solution
A stable power supply should be given to your Hisense TV in the required amount (125 – 210 W) without going too high or low. See if the other electronic devices are working fine or whether they are also facing any sort of issues like your Hisense TV.
If the power supply is on & off, immediately switch off your Hisense TV. Resolve the shortage issue with an electrician’s help or by yourself if you have proper knowledge. After restoring the consistency of the power supply, you can try accessing your Hisense TV. There is a high chance that you won’t be seeing any vertical lines on your TV screen after this stage.
Issues in Connected Device
Sometimes, the problems won’t actually be in your Hisense TV but on the external device you have connected to it. It could be anything like the streaming box/stick, gaming console, or set-top box. So, instead of always keeping an eye on your Hisense TV, turn your attention towards such kinds of TV-linked devices too.
Solution
Unplug the external device that you have connected to your Hisense TV. Now, check if the vertical line appears anywhere on-screen. If not, you are now out of the issue, and your streaming box/gaming console is having some sort of issues, which troubled your TV as well. So, you better avoid using the problematic device with your Hisense TV until you do something to rectify it.
Problems in Channels/Input
If you are using an HDMI box and if the current Hisense TV input has errors, there is a high chance you will get vertical lines displayed. If you are a cable/antenna user, maybe it is having a connection or signal distortion, which is why Hisense TV is showing vertical lines on the screen.
Solution
Thoroughly look for any impairments on your Hisense TV input port. If there is some defect, connect the HDMI cable to the other HDMI port and choose the right input for your Hisense TV.
Even if there is no damage, you can try this to somehow restore the normalcy of your TV. Ensure the cables are damage-free. Now, your Hisense TV will play neatly with a clear picture.
In the case of having an antenna/cable connection, bad weather or technical problems will result in channel loading issues that will display vertical lines. In this scenario, there is nothing to complain about your Hisense TV. You can handle this issue only by waiting till the weather turns normal, or your operator of the particular channel or service fixes the error themselves or after your instruction.
Antenna users can adjust the angle of the dish to receive a better signal and watch TV without distorting vertical lines.
Electronic Interference
This is a very rare factor that causes vertical lines on your Hisense TV screen and a possible one that cannot be ruled out. Signals of certain electronic devices placed near your Hisense TV might interfere with your TV, and it will show fluctuating vertical lines since it can’t pick up signals.
Solution
Walkie-talkies, satellite phones, or computers are the devices that could possibly disrupt your Hisense TV signals. The best way to prevent this is to keep these devices away from the TV.
Outdated/Faulty Hisense TV Firmware
It is essential to consider the firmware if your Hisense TV vertical line issue has not been rectified for a long time. It should always be in its latest version and in the optimal condition to not entangle you in trouble, like Hisense TV screen problems, and function well.
Solution
If you can view the on-screen options and operate your Hisense TV, manage to go to the Settings option and update your Hisense TV firmware. By doing so, the corrupted and miscellaneous agents accumulated with the old firmware flee out, and the display error you went through till now will vanish.
If updating doesn’t help or the firmware has already been updated, reset your Hisense TV using the on-screen menu or unit Reset button. The Reset button can be located on Hisense TVs with Android/Roku OS. Resetting is the final troubleshooting method to try to fix Hisense TV vertical lines from your side, which will mostly bring a favorable outcome.
TV Hardware Errors
If all your troubleshooting wits until now are unsuccessful, then it is time to reach out to an expert to handle this issue because your Hisense TV is being damaged in its sensitive internal parts, which can’t be repaired by users like yourselves.
Solution
Assumingly, the T-Con board of your Hisense TV is going through problems because its ribbon connectors that are touching the screen are loosened. Otherwise, there should be bad signal transmission on the T-Con board or injuries on the Tab boards/video output circuitry.
Remember, even if you have the required tools, seeking professional help is best. Contact the customer support team of Hisense TV [dial 1-888-935-8880, or email service@[email protected]] or take your TV to an authorized service center for repair. Because your TV will become ineligible for a warranty claim or authorized service if you try to open the TV unit and repair it yourself.
The respective authorities will service your TV well and return it to you without any vertical lines troubling your TV streaming.
