lcd panel has a horizontal line across it in stock

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.

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.

In a laptop, the screen is connected using an LVDS or eDP interface, and these just transfer a series of pixel for the screen over and over again, not caring about lines.

Artifacts like bright colored horizontal or vertical lines appear when either the flex cable from the LCD screen IC gets bad connection to the LCD glass or when the glass is chipped or cracked outside the visible area. Then the IC can no longer drive specific column and row conductors to the pixels and the pixels remain either lit or dark.

Another possibility is that the power supply powering the LCD module, including the LCD IC is not providing stable enough power due to deteriorated capacitors. This could explain some horizontal lines, but these lines wouldn"t be solid and would be changing depending on the screen content.

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?

Watching your mobile screen with those white or black vertical/horizontal lines is annoying. In short, it’s tough to use a phone with these lines appearing on the screen. Typically, this issue is associated with the LCD, caused by a faulty hardware component in your device due to some accidental fall or water damage. Phones with such damages can only be fixed at a phone repair center.

However, sometimes the culprit could be an app or software glitch, hindering the functionality of key components like display assembly or motherboard. In that case, you can tackle the situation at home.

Before you head on to the fixes, let’s make your phone data safe. Sometimes, these lines are irreversible, and even the solutions you’re up to try may be followed by some sort of data loss. Therefore, the first thing you should do is make a backup of important files and apps on your device. Some popular ways for data back in Android devices are via:

In case you’re not sure about the process, it’s better to take help from a professional repair center. For Infinix, Itel, and TECNO users, Carlcare Service - being their official service center for these brands- is a recommended place to go.

If there’re white lines on the screen, this solution may prove effective. A battery cycle is when you charge a mobile to 100% and let it drain to 0% again. Usually, the lines will disappear soon as you charge the battery fully.

If the above methods don’t work, it’s time to try this masterstroke. Using your phone in a safe mode will confirm if the lines are because of some faulty app or software.

Check if the lines are gone! If yes (hopefully), then a third-party app is the culprit. Now uninstall the latest downloaded applications until the issue is gone. OR you should try the Solution:4

Suppose the lines are still visible. Then the issue is most likely due to some hardware failure- and the best option for you is to take your device to a reliable repair center.

It won’t be aggregation if you call “Factory Reset” the mother of all solutions. It fixes most of the issues caused by an app or software glitch. The process actually brings your phone back to the factory setting by erasing all the apps and files you’ve downloaded post your phone purchase.

If the horizontal or vertical lines still appear on your phone screen after trying all the above methods, you better take your device to a reliable mobile repair store near you. Most likely, it’s a faulty hardware component that needs to be repaired or replaced. Here, we would suggest you opt for only an authorized service center, as this will ensure flawless repair at a reasonable cost. Besides, if any of the components have to be replaced, they will be genuine and as per your specific requirements.

First of all, since these lines appear during boot up and in the BIOS, this instantly rules out any drivers being to blame as there is no operating system running in these situations, and therefore, no drivers running in that operating system space.

Also, from the description of the issue, this definitely sounds like a hardware issue. If you"re sure your laptop has not been dropped or damaged recently, then this most likely is the screen ribbon cable which has become dislodged from it"s clamp.

It is quite a common issue, more so if a laptop has been dropped or slammed shut, but sometimes they just slip loose. These ribbons cables are flat and are clamped down usually with a tiny lever arm. Sometimes they can become dislodged or slightly twisted and this will cause horizontal lines, bright areas, dim areas, colour bands, and sometimes even total loss of picture output.

Sometimes it is possible to find and fix this ribbon cable yourself (YouTube videos might show you how), but often it will be best to get a qualified technician to take a look at it and let them reseat the ribbon cable for you.

In some instances, the screen itself might be faulty or damaged and cannot be repaired, however, in the large majority of cases I have run into, it will usually be the ribbon cable that just needs reseating.

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.

When you view the same image on both the notebook or All-in-One display and an external display panel (monitor, projector, or television), the image shown on the computer display might shrink to a lower resolution, with black borders around the edges of the reduced display.

This issue can occur when the native display resolution of the computer and the resolution of the external monitor are not the same. When the graphic control detects two displays, it usually defaults to the lower resolution for both devices.

To resolve this issue, disconnect the external monitor to verify that the resolution on the computer display changes back to the desired settings. Reconnect the external monitor, and then adjust the resolution settings for each device using one of the following methods:

To use Windows to control the graphic display, connect both displays, right-click the desktop, select Screen Resolution, and then change the resolution for each display. On some models, you can select an advanced option to either Duplicate the same image on both displays or Extend the desktop image across both displays.

Certain computer models that feature a high-performance chip or secondary graphics processing unit (GPU) have an advanced graphics maintenance function. Names of advanced graphics options may vary. To use an advanced graphics maintenance function (if available) to control the graphics display, right-click on the desktop and select one of the following options:

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.

I have recently noticed a thin, horizontal line across the middle of my retina Macbook Pro display. At first glance , it looks like a smudge, but upon further inspection, I see that it is permanent and will not come off. It"s definitely not a problem with the display backlight/pixels, as I can still see it when the display is turned off, however, it"s too thick to be a scratch. Has anyone else ever seen anything like this? If so, is there any way to fix it?

Whenever i turn my laptop on, after using for 15-20mins/ half an hour the horizontal line on the top of the display showed itself, and vibrate continuously. It get bigger in width slowly.
