lcd panel has a horizontal line across it for sale

LCD display screens on notebooks, monitors and TVs alike are made up of two thin layers of glass containing liquid crystal material between them. When the glass becomes damaged, debris infiltrates the crystal layer or another issue occurs with the display function, this causes vertical lines of color to appear when the monitor is fully illuminated. These lines are either permanent due to internal failure or temporary due to faulty display connections.

Diagonal, jagged and both horizontal and vertical lines typically indicate panel damage. A single set of horizontal lines could indicate damage, a graphics system failure, or loose internal video cables. Broken signals from cables or graphics hardware creates impurities in reproducing an image on an LCD screen, conditions that often manifest in the form of vertical or horizontal lines of color.

If the lines are infrequent in their appearance, or are not permanently visible, a loose video cable is often the problem. As devices are carried, dropped and bumped, cables become loose even in laptops. Laptops are built with casing to absorb and dissipate small shocks, but even some bumps can cause cables to become loose. Even televisions and monitors, while often stationary, can still have loose cables if not properly seated.

If you"ve ever opened your laptop to clean underneath the keyboard, you might see numerous things like food particles, hair or even dust. On the rear of monitors and televisions, they also contain a series of holes or slits that dust can creep into the inner workings and cause problems. Regularly cleaning out a laptop"s keyboard and dusting off the rear of a monitor or television can greatly extend its useful life. This is a preventative measure and rarely works in removing any existing lines on a screen.

The first step in troubleshooting is determining the extent of the damage. For external monitors or televisions, re-seat any video input cables or consider replacing the cables with new ones. Should the lines continue to display, this indicates an internal failure, something few consumers are able to fix on their own. Instructions exist online for individual products to disassemble a monitor, laptop or television to replace broken parts, but the most suggested course of action is shipping it to the manufacturer for a warranty repair. If no warranty is active for the device, consumers are then advised to replace the device entirely with a new one, as this is usually the cheapest solution. Lines on an LCD panel indicate the LCD screen or screen ribbon cable need to be replaced, parts that can cost several hundred dollars.

Ours is a Sony Bravia that is now over 10 years old. Several months ago we started noticing lines, especially on the left (our left) side of the screen. They’d go away after the tv warmed up. Then we started noticing it was darker on that side of the screen, but again, after the tv warmed up the screen would be normal. Then about two months ago it started getting worse and didn’t ever get completely better, even after the tv warmed up. So I watched some youtube videos that all talked about the ribbon cables becoming loose over time and to apply pressure along the top and see if that made it better, and if so, it was a loose cable and if you put electrical tape or something that would help keep the pressure, it would fix the problem. Hubby pressed along the top and sure enough, when he pressed in one spot on the left side suddenly the picture cleared up. Stayed good for about a week, then problems again, pressed again, fixed again. A week or so later, same problem, but this time when he pressed on it nothing got better.

So I decided to take the cover off and look at it better. As I was pressing on the tops of the ribbon cables that run down from the top of the frame, for a minute it got better but then suddenly there was a wide white vertical line, with a thin green one down the center of it, running down the front of the screen, and it was perfectly aligned with one of the cables. So now I still have the dark side of the screen, and some ghosting, and some lines, but now this bright white streak/line right down the front. Another weird thing is that if the whole screen is bright (like watching a show set in a snowy place) then the darkness even on the left side is basically gone, but if the scene is dark at all, that side is almost black. I don’t know if it means that particular ribbon cable is bad, or if something is loose, if things need to be replaced or what. It’s very frustrating as it’s been a great tv. Hubby wants to just buy a new one, but even if he does I would still like to try and figure out this one as it could then go in another room.

If your TV is still under warranty (if it is less than one year old it probably is), I"d call Geek Squad and have them look at it, although it sounds to me as if there may be a problem with the LCD display panel. Was the set recently struck or dropped? Remember, flat screen televisions, unlike CRT (picture tube) sets, are very unforgiving when it comes to occurrences such as this; once the panel is broken, you have no recourse but to get a new TV.

Had this TV for less than a year, and when I went to switch to Blu-Ray player, there was a very noitceable line going horziontally across the whole screen. It is very frustrating and pretty much unwatchable. Sometimes the line is red, others it is black or even a turqoise-like color. I tried different HDMI cords, unplugged everything, different outlets, and the line is still there no matter what. No inputs are even plugged in and the line is still there.

TV screen lines are an irritating occurrence, and many different issues with the TV can cause them. This article will go over what causes this, whether or not you can fix it depending on the cause, and how to fix it.

When any part of a TV"s display gets damaged, corrupted, or is defective, it can cause lines to appear on the screen. Some TV parts that can cause horizontal lines to appear are the LCD panel, T-Con board, or row drivers.

Issues with these parts can happen for many reasons, and the way your lines appear can tell you a lot about what"s wrong. If the lines are new, one of these parts was likely damaged.

If you"re seeing colored horizontal lines, it may be because of the T-Con board. If other parts don"t seem to be an issue, this part of the TV could be causing the lines.

If lines appear on your TV, you"ll want to inspect the TV itself. You can fix some issues that cause lines to appear, but others may require a professional or a new TV altogether. Some of the most common causes of horizontal lines are:

LCD screen damage. The LCD provides your TV display with light. If you"re handy, you might be able to fix this by doing a little work with the insides of the TV, which you can read about below.

Other devices you"ve connected to the TV. They may also be having issues of their own or might not be compatible with your TV. In this case, you"ll have to inspect the device instead of the TV.

All these issues can be fixed, though it ranges in difficulty. If you"re unsure how to repair your TV, you may want to get the TV professionally repaired.

Knock or tap on the back of your TV. If the issue is with cable connections, this could solve the problem. It could also indicate a problem with your T-Con board. It won"t fix the issue, and the lines may reappear, but it can give some insight into the problem. If it"s your T-Con board, you"ll want to have T-Con replaced.

Change your TV"s settings. This step might work for you if the issue isn"t because of damage. First, try switching the TV input from different HDMI ports or AV ports. Doing this can rule out problems with specific inputs.

Run a picture test on your TV. It"s a built-in feature on newer TV"s which allows you to see if the TV display is corrupted. Doing this may look different depending on your TV, but generally, you can go into the settings and find a support option or just a picture test option.

Take a look at the LCD screen. If it"s damaged, you may want to get the screen repaired or replaced. It may be a less costly option than buying a new TV altogether.

Vertical lines on a TV appear for the same reasons as horizontal lines: loose cables and wires, screen damage, or a faulty T-Con board. Leaving the TV turned on for too long can also cause vertical lines.

The steps for fixing lines on your TV will also work to fix TV glitches like flicker and stutter. For example, check the cables and connectors and ensure there"s no issue with your input device.

If your TV screen looks blue, it could be faulty connections, a defective backlight, or incorrect color settings. Some LED TVs naturally have a blue tint, which you can offset by changing the color temperature.

To fix screen burn on a TV, adjust the brightness settings and enable pixel-shift. Sometimes playing a colorful video with fast-moving action for half an hour might help.

The appearance of static or flickering horizontal lines on a computer screen can be frustrating and inconvenient, but there are many steps you can take to try to fix your problem. This guide will walk you through various checks and fixes you can perform on your computer and its monitor to find out why the lines are appearing and what to do to make them disappear.

Horizontal lines on a computer monitor can be caused by overheating or physical damage to the monitor and connecting cables. Conflicts between the screen and selected screen resolution and refresh rate settings can also cause line problems, as can out-of-date device drivers and operating systems.

Try a different monitor. If possible, try connecting to a different monitor or screen. It can help you determine if the lines are caused by your computer’s screen or the computer itself.

Check your monitor while it’s disconnected. Keep your monitor powered on, unplug it from your computer, and look for any flickering or lines on its screen while it’s disconnected. If you see any kind of distortion, this means that your monitor is damaged.

Close and reopen your laptop. Close your laptop’s screen, wait a few seconds, and reopen it again slowly. Look to see when the lines begin to appear on the screen as you open the laptop. If the lines only occur at a certain angle, the cause is likely damaged wiring.

Check the monitor connection. Ensure all of the cables are securely connected, and watch for any improvements in screen image quality while you’re inspecting the cables. If you notice the image improves or worsens while touching the connecting cable, it may need replacement.

Remove magnets and electronics. If you have other electronics or magnetic devices near your computer, screen, or the connecting cables, move them somewhere else as they may interfere with the connection and cause the lines.

Calibrate your monitor. This process should only take a few minutes and can help optimize your monitor for use with your computer and its environment.

Run a troubleshooter. Open Settings and select System > Troubleshoot > Other trouble-shooters and run the Video Playback and Program Compatibility trouble-shooters. If you get presented with any recommendations for other trouble-shooters, run those too.

Reset your monitor to its factory settings. If you’re using an external monitor or screen, use its built-in settings, not your computer’s settings, to reset it to its factory settings. You can usually access these settings via a physical Settings or Menu button on the computer monitor itself.

If your monitor is displaying a message that reads "no input signal," you may have a defective cable or component. To troubleshoot the issue, turn your computer off and on again. Also, unplug the monitor-to-PC cable and plug it back in, making sure the connection is secure. Try another monitor to see if the problem is with your PC. Also, try resetting your video card; if nothing else works, replace your video card.

To fix coloration and distortion on a computer screen, power the monitor on and off, restart the computer, and make sure the cable between the monitor and computer is connected securely. If you"re using a CRT screen, try degaussing the monitor. You can also try adjusting your video card"s quality settings and experimenting with your monitor"s adjustment buttons.

To fix screen burn on a monitor, also called "ghosting," try turning off your display, ideally for at least 48 hours. Also, try setting your screensaver to an all-white image and letting it run for a few hours. You can also try using the JScreenFix tool, which fixes stuck pixels.

Vertical and horizontal lines on the best desktop monitors can ruin the immersive effect from your display, which is especially frustrating if you’ve invested into your monitor, like one of the best curved gaming monitors. To find out how to fix annoying vertical lines or horizontal lines on an external monitor, you’ll first want to test the picture to find out what causes these lines on the computer monitor, whether the problem is from the PC, cable box or another input source, or if the fault is with the monitor, its LCD panel or internal hardware itself. And while on the topic of “vertical” lines, there are vertical monitors that exist to help make certain professions or hobbies more efficient, like coding and streaming.

Before attempting any other troubleshooting, such as fixing black bars on the side of your monitor, the first step toward finding solutions for this desktop monitor problem is to isolate the source of the issue.

The first option is to test out the image on your favorite computer screen without any peripherals connected. To do this, disconnect all cable connections and use the remote control or the control panel to disconnect Bluetooth and WiFi, if your external monitor is so equipped. If there are no vertical or horizontal lines on the default picture or menu screen, then the problem is likely due to your PC or input device, or to your cable connections. If the lines still appear, then the issue is likely to be with the external monitor itself.

If the monitor shows lines when not connected to any cables or input method, the problem is likely with the monitor itself. Image issues such as lines can be caused by damaged internal ribbon cables or the LCD panel itself. If this is the case, the repair process will depend on what the hardware problem is, whether you have a flat or curved computer monitor. If you see light leaking on the edges of your monitor screen, you may have blacklight bleed, which you can learn about in our resource content on what is blacklight bleed.

If the lines go away when your external monitor has no input, then you’ll want to look for a connection issue or an issue with your PC or laptop’s graphics drivers, driver settings, or picture settings. Additionally, you may want to check for any input lag issues with your monitor at this time.

Make sure all cables are connected securely. A loose connector can cause various picture issues including gray lines, pink lines or green lines.You may want to unplug your monitor from the input device and check the condition of the ports. You may be able to see if there are any bent or broken pins in the connectors of these input terminals. Double-check the cables if you have two monitors. If you need more organization in your space, consider the best dual monitor mount. Don’t use a paperclip or other metal object to try and clear out a VGA terminal.

If you find a damaged part, you can either consult a repair service or professional repair technician, or you might want to fix it yourself using an electronics repair kit. Use caution when removing ports, and always unplug a monitor before working on a repair.You may need to consult the owners manuals to see what types of repair tools will be needed.If the cable is faulty, the solution may be just to buy a replacement cable. That may be the best path if you need to immediately fix your monitor and can’t spend time researching and repairing the damaged part on your own, like if you use your monitor for work like a monitor for video editing.

Look for any video card drivers or graphics card driver that has a yellow exclamation mark or question mark. These common error notifications may mean your laptop or PC graphics drivers are out of date. Many graphics cards offer a driver updater tool. You can also consider buying a new, updated graphics card.

Alternatively, you can run a system scan to discover errors and graphics driver software issues. If there is a problem with your graphics card driver, it may show up on a system scan. Try booting up in safe mode or BIOS, if available; this will often show whether the display issue is a software problem or a hardware problem.

Warning: Try booting up in safe mode or BIOS, if available; this will often show whether the display issue is a software problem or a hardware problem

A screen resolution adjustment may also help. If the device picture settings are not compatible with the monitor’s native resolution, you may see errors such as lines on the screen. On a windows PC, setting a display resolution or refresh rate that is not supported can damage a monitor.This is more often a risk with older CRT monitors.

Warning: If the device picture settings are not compatible with the monitor’s native resolution, you may see errors such as lines on the screen. On a windows PC, setting a display resolution or refresh rate that is not supported can damage a monitor

You can definitively confirm the fault by running a screen diagnostic - hold D through powerup. If the fault appears on the test screens (it almost certainly will), the screen must be replaced.

Due to the fact that the issue is isolated to a single line (even with multiple pixels in height) it"s unlikely it"s the actual signal (e.g. cable or connector pins).

Some issue with the connection would most likely screw up several lines and/or the whole image and it won"t be isolated to exactly one line (especially with digital connections).

In a similar way, issues with the graphics card should most likely cause issues with the whole screen (like garbage/random patterns). Those shouldn"t be isolated to a single line.

Turn off the monitor, disconnect all cables, and put it flat on your table (screen up) so it"s sitting plane on the table. Let it sit there for a night, then try again.

If everything else fails, what happens if you use your finger nail and pull it over the faulty line? Don"t push too hard, just so there"s some pressure (typically shows some short colored trail that should disappear within 1-2 seconds). Can you see any additional patterns or "waves" that don"t fit to what you see in other areas of the screen?

I am sorry to hear about the inconvenience. This could be an issue with the graphics driver on your computer. Do these lines also appear when your first start the computer? (Before windows is loaded). If so, the issue could be your graphics hardware. If it only happens inside windows, let"s try to reinstall the graphics drivers. Here"s how:

If the above does not help, you may also download the graphics drivers directly from your computer manufacturer"s website if what you have is a laptop. If it is a desktop, you may download the drivers from your graphics card manufacturer website.

Here are 3 fixes that have helped other users resolve the horizontal lines on laptop screen issue. You may not have to try all of them; just work your way down the list until the problem is resolved.

This problem may occur if you are using the wrong graphics driver or its out of date. So you should update your graphics driver to see if it fixes your problem. If you don’t have the time, patience or skills to update the driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

You can update your drivers automatically with either Free or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

3) Click Update All to automatically download and install the correct version of ALL the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

4) Restart your computer and see if the horizontal lines on screen issue has been fixed. If yes, then great! But if the problem persists, move on to Fix 2, below.

If the fixes above didn’t help with the problem, then it’s most likely a hardware problem. You can power off the computer and then gently wipe across the screen with cotton balls. Be sure to proceed with caution so as not to cause any further damage to your laptop.

That’s it – three fixes for you to fix the horizontal line on laptop screen issue. Have you resolved the problem successfully? Please let us know in the comments. Thanks for reading!

Another thing I can think to try is review the HP Support document: Changing Display Settings, Background Image, Icons, and Screen Saver (Windows 7) to see if you can identify anything out of place.

As awesome as they are, most Apple MacBook models do tend to have some flaw - design or build quality related - and quite often that flaw blows up massively. After endless discussions on online forums, avalanche of tech articles, petitions and lawsuits, the defect is acknowledged by the company. In some cases, they even start a “Quality Program”, under which the affected devices are offered a free service even outside warranty. Some of the major “defects” over the years have been MacBook Pro 15inch Battery Issue, Butterfly keyboard issue, FlexGate: MacBook Pro Display Backlight Issue etc.

What are the symptoms?The MacBook Pro screen starts to develop grey or black horizontal lines from the bottom edge (sometimes the top), typically 1-2 cm “tall”. This band of lines is often flickering/strobing.

Note: Is your MacBook display showing Stage Light Effect - alternatively bright & dim areas along the bottom of the display? Or is it going blank when you open the lid beyond a certain angle? If yes, it is not a T-CON board issue. Although both impact the same MacBook models, that issue is actually entirely different. Read about it here:Flexgate: MacBook Pro display backlight issue - Is it repairable?

Technically, all MacBook Pro models launched after 2016, with an Intel CPU chip inside, would be vulnerable to this issue. These include 13 inch, 15 inch, even 16 inch devices. Model Numbers: A1706, A1707, A1708, A1989, A1990, A2159, A2141. MacBooks with Apple M1 chips are considered safe.

However, in our experience here at Fixxo, the 13 inch MacBook Pro non Touch Bar model 2016-17 (Model A1708) is the most frequently impacted model. There is a technical explanation for this. Read on.

It is believed to be a design flaw from Apple. Poor thermal management leads to the display logic board (T-CON board) getting cooked from overheating.

All MacBook displays have a small logic board of their own. Up until 2015 this board used to be tucked inside the hinge cover at the bottom edge of the display. It was part of the “lid”, removed from the main chassis. 2016 onwards, this board, while still being connected to the display, sits inside the top case or main chassis (read: keyboard panel). It is mounted very close to the heatsink radiator.

Disclaimer: Please be informed that this explanation is offered by independent experts (hat tip to Mr Dan at iFixit). Apple hasn’t verified this theory. For more discussion around it check this and this.

Simple - the 13 inch non Touch Bar model (A1708) has a single internal Fan, while most of the other MacBook Pro models 2016 onwards, have two (don’t ask why!). This leads to insufficient heat management, ergo higher chances of conking off.

Yes, but it is expensive - getting the display replaced. The T-CON board is attached to the display assembly, and there’s no way to replace the board alone. So, display assembly replacement is the only real, sure-shot solution.

“If it is a design flaw, won’t my new display also get damaged?” you ask? Good question. Unfortunately, yes, you do run that risk. But, now, with this new-found knowledge, you can proactively avoid any overheating in your MacBook. Read the What can I do to avoid this? section below. Follow that, and you can almost certainly avoid recurrence.

If your device is still under warranty, you’re in luck! For a free replacement, walk in to an Apple Authorized Service Provider (there are a number of fake AASPs around, careful!). If the warranty has expired, consider bringing it to us at Fixxo, for competitive pricing, top-notch quality, great customer support and quick TATs!

Well, I wish I could say “yes”. Your only hope really is that you have alerted at a very early stage of this “ailment”.Shut down the MacBook. Let it cool overnight. Try using again the next day - if the lines don’t reappear after a couple of hours, voila! Do read the next section for precautions.

If those stubborn lines keep reappearing, well, it is only a matter of time. Display assembly replacement is the only end-game. To delay the inevitable, read the next section.

[Secret Tip: Some users have reported to have successfully squeezed a free out-of-warranty replacement from Apple. Maybe try that if you’re feeling lucky!]

Never use these MacBooks (or any laptops for that matter) on the bed or a pillow. For better airflow and ventilation, keep the MacBook on a table or a hard surface.

Well, what can you say. Apple hasn’t acknowledged there is a design flaw. The good news is that there is a lot of pressure building up online towards this cause [too little, too late?]. If and when Apple does relent, it’ll appear on the Apple Service Programs page. Keep checking!

Until then, to support the campaign, you can sign this petition, provide feedback to Apple, or just visit an AASP and (politely) give them a piece of your mind.

I’m a TV enthusiast, and I know the feeling. The pesky rolling bars can get on your nerves because they make it hard to focus on what you’re watching.

There is nothing to worry about though, your TV isn’t dead yet. The annoying lines can be due to loose connections, poor signals, outdated software, or internal problems.

To rule out this possibility, ensure the cables connecting the device to your TV are in perfect shape and securely connected. Test your TV with another video input to confirm this.

Disconnect all devices from the TV. Let each device boot up, then plug them back in one at a time. Take notice if any of the devices cause the horizontal lines to reappear.

Another common cause of horizontal lines on a TV is interference from other electronic devices. EM interference occurs when two devices with different electrical properties are in proximity to one another.

Most modern TVs feature anti-interference technology to prevent interference from nearby devices such as wireless routers and microwaves. The screen may display those annoying horizontal lines if this technology isn’t working correctly.

You could also have horizontal lines on your TV from other devices in your neighbourhood. EMI is particularly common in apartments with many electric appliances.

Faulty and loose connections are the most common cause of horizontal lines on a TV. If you recently moved your TV, you might not have properly connected the cables.

Poor signal quality from cable or satellite services could result in rolling horizontal lines. The problem is more likely to occur when watching standard-definition channels over high-definition ones.

You can check the TV signal quality from your receiver or box by connecting another device directly to your TV. If there are no horizontal lines on the screen when using another device, it’s likely that the box or receiver has a poor signal.

A damp screen causes moisture to build up behind the glass of your television, causing image distortion. You should clean or dry your TV as soon as possible after noticing these issues to prevent further damage.

If you live in a place with high humidity, you may have a problem with condensation on the screen. This can occur when using your TV in an environment that’s too warm, such as an enclosed room or cupboard without proper ventilation.

The solution to this problem is straightforward. Wipe your TV screen with a soft cloth to remove all dust and dirt. And if possible, watch your TV in a well-ventilated room.

Damaged liquid crystal displays (LCDs) can cause horizontal lines on your TV screen. These lines may appear as one continuous line or as multiple lines equally spaced apart.

Vibrations, heat, and voltage surges can damage LCD screens. To fix these horizontal lines on your TV, you will need to replace the damaged LCD screen.

If you are handy, consider re-soldering any faulty connections to prevent any damage to other parts. However, if your warranty is still valid, doing this will void it. I would advise that you only do this when your warranty has expired.

A row driver circuit sends signals from the microprocessor to each pixel row on the display panel within an LCD panel. When one or more pixels in a row go bad, it can cause lines across your screen. To fix this, you will need to replace the failed row driver.

Most manufacturers list common issues and their solutions in the manual. If you don’t have your copy of the user manual, you can most likely download it over the internet.

Turn off the TV, unplug all cables, and wait 30 seconds. Next, plug in the power cable and turn it back on. If this does not work, proceed with the next step.

Hitting the back of the TV with the palm of your hand helps to dislodge dirt. Hits can also help restore loose connections, though this is only a temporary solution.

Give your TV a few smacks while checking if the horizontal lines disappear. However, do not hit it hard as you could end up damaging it instead of resolving the lines.

Ensure all the cables and wires connecting your TV to other devices are in good shape. Connect each cable and wire securely and replace worn-out cables and antennas.

Connect your satellite or cable box directly to the wall socket instead of a splitter or power strip. Connect any loose or disconnected wires and then try watching TV.

If the lines are still there, disconnect and reconnect everything again and see if your picture improves. If the rolling lines do not disappear, move on to the next step.

This is especially important if you’ve recently moved or transported your set. Screws can loosen over time or during transport, so make sure to double-check them.

Go to the manufacturer’s website and download the latest firmware version. You can perform the update by connecting a USB drive to your computer and running the software.

Connect your TV to a Wi-Fi or Ethernet network. Connect it to Wi-Fi or Ethernet with a strong signal if you have a smart TV. Update your television’s software by going to Settings > System > Software Update > Network Update > Download Now. The update should resolve any issues caused by outdated software running on your device’s hardware components.

Static electricity can also produce moving horizontal lines on a television screen. It interferes with the way cable boxes and satellite dishes process signals.

Increase the frequency of image refresh on your TV by pressing the up button on your remote control. Or press the down arrow button to reduce the refresh rate.

Please note that these steps may vary across brands. That said, the above steps will apply to most Android TVs. If you have a Samsung or Sony Bravia, below are the steps to follow:

Detach the back cover of your TV by unscrewing all screws holding it in place. Use a screwdriver that fits precisely into each screw head to prevent the screws from being stripped

Keep in mind however that these steps may vary depending on the brand of TV you own. Be sure to check what the user manual says or contact customer support for further guidance.

Do not worry if you are not comfortable working with electrical equipment or do not want to risk damaging your TV. We recommend hiring a professional service to help you diagnose and replace a faulty T-Con Board.

If you have tried every tip above and nothing seems to fix the problem, then you’ll need to factory reset your TV. Resetting it will restore its original settings and should fix any glitches.

First, turn off your TV and unplug it from the wall socket. Wait for at least 10 seconds before plugging it back in and turning it on again. This will reset the power supply to the device.

Next, press and hold the power button on the remote control until the TV turns off again. Release the remote’s power button and wait a few seconds before pressing it again, only once, to restart your TV.

Now that you’ve restarted your TV, perform a factory reset by following these steps: These steps may vary depending on the TV’s brand. If you have a Sony Bravia TV for instance,

Contact customer support if you have ruled out external factors causing the horizontal lines on your TV, and they’re still there. The company will ‌help you identify the problem and offer a solution.
