lcd panel has a horizontal line across it manufacturer

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.

However, you don’t have to go through this. With horizontal lines appearing on your TV screen, you can still hope to restore the image back to normal.

A TV is an electronic device; hence a scanned system that develops horizontal lines to form a picture. However, the problem arises when some of these lines appear on the screen itself.

If an external port/device is connected to your TV, then you must check if its connections and picture format settings align with that of your TV- the Aspect ratio, screen resolution, and scan frequencies because these are notable for the picture display.

Yeah! It might sound like you are gonna tear up a mountain, but go through the steps I am gonna share below and you will be able to open your TV apart!

2. Once you open it, you will see a number of circuit boards and wires inside the TV- let’s say power supplies, transistor, T-con boards, IR sensors, capacitors (batteries), controller boards, signal inputs, inverters, and many more.

1. Take the T-con (time control) board to figure out where these row signals are. Otherwise, you won’t be having any clue as to which signals need to block.

2. The abbreviations are different in terms of different LCDs. In such cases, look for the abbreviations shortly mentioned on the panel(it is mostly written on the right side).

3. Use a multimeter in a continuity setting. It beeps when there is an electrical connection so you can easily find the corresponding set of signals since they are sent to both sides.

Now if you block all the row signals on the ribbon cable yet are unable to get a good image then you can use trial and error and unblock them in different combinations and or one at a time until you get your desired image.

It is wiser to use a Display quality troubleshooter to determine the range of the damage before you think of replacing a new one. Here are a few troubleshooting steps you must follow:

2. Switch channels and check if the lines keep appearing on all channels. Switch to a different input source (HDMI, PC, and more) if that keeps happening.

3. You can also run a picture test to determine if your TV is faulty or not. Press the Menu bar and then pull up Settings using the directional pad on your remote.

6. If your TV does not include the Picture Test option, you can identify the problem using a USB drive. Try troubleshooting in the same steps explained above.

Remember this: Whenever you hit the re-set button, all the settings of your TV will turn back to Factory default. This includes the removal of your pictures, audio, timer, and other settings. So write down the important settings before you start.

Sometimes you will see green horizontal lines appearing on the middle of your TV screen. This mostly happens if your power supply is fluctuating as per the needs of your TV to function smoothly.

Hopefully, these tips would work perfectly for your TV. Wouldn’t it be worth it if you could fix it yourself and extend its longevity for a few more years?

So, if you have tried all of these steps and yet there are visible horizontal lines on the TV screen, take it to an authorized service center to repair or replace it with a new one.

The clock signals from the T-con board tell the transistors in a specific row to turn on one row at a time. When they are on, they accept the image data that is sent to them.

I have covered all the possible reasons as well as effective solutions on what causes horizontal lines on the TV screens. Try these solution methods and let me know if they work in your case.

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.

Valerie Goodwin  horizontal lines are almost always a fault of the LCD driver board. That particular board is part of the LCD panel and thus not separately replaceable. Of course, you always want to check the wiring on the inside of your TV. Disconnect the wiring and then reseat those. Make sure that all of them are properly seated. Let us know the exact model for your TV so we can try to assist you further.

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.

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.

On the other hand, they often get hardware related problems in their Smart TV. For example, they require fixing the horizontal lines on the TV screen. It is the right time to know about the main causes horizontal lines on TV screen and start a step to fix such problem.

There are two thin layers of the glass containing high-quality liquid crystal material between such layers in the LCD display screens on the TVs, monitors and notebooks.

If such glass becomes damaged over time or because of any accident, then the debris infiltrates the liquid crystal layer and causes the color’s vertical lines appear when the entire monitor is illuminated. These lines are temporary because the faulty display connections and permanent due to the internal failure.

Horizontal, vertical, jagged and diagonal lines on the LCD screen indicate the panel damage.  If you get a single set of horizontal lines across TV screen in recent times, then there is damage in the internal part, a loose internal video cable or a graphics system failure.

All broken signals from graphics hardware or cables make impurities in the reproduction of the image on the screen. You can contact the company specialized in the TV screen repair services and get the customized yet affordable service to get your TV screen back in a good condition.

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!

This problem occurs because of a hardware limitation that is known as "tearing." Tearing is a video artifact in which the top portion of the screen shows a different frame of video than the bottom portion. This is more noticeable during scenes that contain fast motion. There may be a noticeable horizontal line at the point where the two frames meet.

When it is playing video content such as a DVD, the operating system has to synchronize playback with the display redraw rate. The video frame is updated during the vertical blanking interval so that the complete, correct frame will be displayed without any tearing every time that the video card refreshes the monitor.

When windows synchronizes DVD playback with the monitor refresh rate, it synchronizes with the timing of the primary monitor. This is determined by the video driver. Some video hardware supports multiple monitors but does not synchronize the display redraw timing of the two monitors. Even though the two monitors are configured for the same refresh rate (for example, 60 Hz), the second monitor may not be refreshed at the same time. In this case, there may be unavoidable tearing on the second monitor.Resolution

If the computer system meets the hardware and software requirements to run Windows Aero, you may be able to reduce or eliminate the problem by enabling Aero. Otherwise, set the display to PC Only or Extended. For more information about Aero, go to the following Microsoft website:

If your computer does not meet the requirements for Aero, set the display to PC Only or Extended. For information about how to change this setting, go to the following Microsoft website:

If you experience noticeable cut lines or tearing, and not only when you play a DVD movie, the display may be configured to a refresh rate that one of your monitors does not support. If this is the case, you can resolve the issue by configuring the display to a refresh rate that is supported by all monitors.

Select a resolution and refresh rate that is supported by all monitors. (Your monitors may support multiple refresh rates. See your manufacturer"s documentation for information about the settings that your monitor supports.)

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.

If the screen flickers, make sure the display settings in Windows match the native resolution and refresh rate for the display. Find the native resolution of a flat panel display on the box, in the specifications, or in the printed material that came with the display. Some common native resolutions are 800 x 600, 1024 x 768, 1920 x 1200, and 1680 x 1050. The most common refresh rate for LCD displays is 60 Hz. This normally cannot be changed for flat panel displays using Plug and Play settings. However, if you are using special video software to increase or decrease the refresh rate, change the refresh rate to match the default refresh rate specification of the display.

If your screen flickers in Windows 10, it is usually caused by incompatible apps or display drivers. To find out whether an app or driver is causing the problem, check to see if Task Manager flickers. Then, based on that information, you"ll need to either uninstall the app or update the display driver.

Otherwise, you can get the latest updated video drivers from the video hardware manufacturer"s website. The following list shows some of the video hardware websites:

If you cannot select the native resolution after updating the video drivers, the graphics adapter in the computer might not support that resolution and might need to be upgraded.

Check the video cable connections. Unplug the cable and inspect the cable for damage. If the cable is damaged, replace it with a new cable. Try to use cables less than 3 meters (10 feet).

Check the environment around the display. Displays are sensitive to magnetic fields. Speakers, florescent lights, fans, cell phones, radios, and any other electrical device can cause flickering. Temporarily move electrical items away from the display to see if they is producing a field that causes the flicker.

To see if the video coming from the computer is causing the problem, temporarily connect the display to another computer, such as a notebook computer.

If the flicker is gone when the display is connected to another computer, the graphics adapter hardware on the first computer might need to be upgraded to use the display.

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

So you’ve noticed horizontal lines on your Samsung TV, and you’re wondering if there’s a way to fix it. Horizontal lines are a common problem with LCD TVs. Most people will resort to throwing away their TV when it gets horizontal lines, but you can often fix the issue on your own.

The lines you’re seeing may be very obvious, or more subtle, like a light shade of grey. Most of the time, the horizontal lines are caused by a hardware issue. Luckily, I’ve found a few proven ways to fix horizontal lines on a Samsung TV.

Here’s how to fix horizontal lines on your Samsung TV screen: Unplug your TV from the wall outlet for 60 seconds, reseat all HDMI cables, remove the back panel and spray compressed air to clean out dust, reseat the T-CON board ribbons, or place a strip of tape to block specific contact points on the T-CON ribbon cable.

I’ll expand on the above solutions in more detail below. Bear in mind, that before you remove the back panel on your TV and attempt a DIY hardware fix, I recommend checking your TV’s warranty.

If your TV has a valid warranty, the easiest solution would be to contact Samsung for a replacement. In most cases removing the back panel on your TV will void your warranty, so it’s best left as a last resort.

While this fix sounds obvious, unplugging your Samsung TV from the wall socket is the most common way to get rid of the horizontal lines you’re seeing.

The key here is to actually wait the FULL 60 seconds. Have a little bit of patience and make sure it’s been at least a minute before plugging it back in.

While the TV is unplugged, find and hold the power button on your Samsung TV for 30 seconds. Make sure you are holding the power button on your TV, and not your remote.

This will help to drain any residual power left in the TV and allows the TV to soft reset itself. This is different than simply switching the remote on and off!

Disconnect all external connections from your TV and then reconnect them. It will only take a couple of minutes and it’s an easy way to troubleshoot what is causing the issue.

In most cases, the company will provide you with a replacement TV if you have an active warranty. While horizontal lines are more common on old LCD TVs, they can occur on new TVs too.

NOTE: The following fixes involve removing the back panel of the Samsung TV. If you’re not comfortable with DIY hardware fixes, I recommend contacting Samsung for advice (see below for contact info). Also, I do not recommend removing the back panel on a new TV because it will void the warranty.

One of the main causes of horizontal lines on a Samsung TV is the pins on the T-CON ribbon cables do not have full contact with the connectors. Little bits of dust and debris could have entered the cracks and blocked the pins.

Old TVs usually have quite a bit of dust and grime inside, which can cause a wide range of issues. You can use a brush with fine bristles to wipe away the dust.

When you remove the back panel of your TV you’ll see the T-CON board with one or two ribbon cables. Gently remove the ribbon cables, wipe them down, and then reconnect them.

You can often remove the horizontal lines on a Samsung TV by blocking certain contact points on the ribbon cable that connects to your T-CON board. I’ll walk you through the steps below.

If the lines only appear on one side, you can potentially fix the issue using a small strip of tape.Unfortunately, when lines run across your entire display, that is most likely a serious hardware issue that you won’t be able to fix.

In the case where there are lines on only one side, I have a DIY solution. To test which side of your TV has the issue, keep your TV plugged in, and remove one ribbon cable at a time. Each cable will provide a signal to one side of your screen.

Once you isolated the ribbon cable that carries the signal to the side of the TV that has horizontal lines, we’re going to use tape to block specific pins on that cable.

Finding out the exact pins to block on the board is challenging and you might need to look up the panel specifications of your Samsung TV model. You could also use trial and error, using tape to block certain parts of the contact points, until you find the right location.

Once you find the pins that are sending signals to the area of the panel that has an issue, you can narrow down the strip of tape until it eliminates the exact horizontal line location.

The pins on the ribbon cables each send signals to a certain location on the TV panel. The idea is to block the signals that are being sent to the area that is creating the horizontal lines.

Most of the time, the TV will recalibrate and one side will fill in the blanks. The image might dimmer on the problematic side but the horizontal lines should be gone or at least much less obvious.
