lcd screen vertical lines manufacturer

Vertical lines appearing on LCD screen is very common. Whether the screen belongs to a laptop computer or desktop PC, mobile phone, or even a television, the fault is usually due to the ribbon cable and its connections.

A faulty ribbon cable can cause all sorts of havoc manifesting in bright vertical lines. Sometimes they can be coloured lines such as blue, green, grey, black, and red. The lines can appear thick or thin and on just one-half of the screen. Sometimes the fault will manifest as two vertical white lines. You can even get horizontal lines as well.

If you have lines appearing on the LCD screen, then the first simple thing to check is the seating of the ribbon cable that connects the display panel to the motherboard. Most of the time, the fault is with the poor connection made by the ribbon cable.

One of the most common problems with ribbon cables is oxidation of the contacts. It can happen either on the ribbon cable contacts or on the socket contacts. Manufacturers often use a mix of gold and copper for the electrical contacts, however, if they have not used enough gold, then oxidation occurs over time. This results in a working television or laptop screen suddenly exhibiting lines.

One of the most common faults with laptops is that the ribbon cable connecting to the LCD panel cracks. It typically fails near the hinge area due to flexing in that region, and over time, some of the tracks on the plastic cable breaks. I have seen these types of faults on many laptops. It does not matter whether it is a Lenovo, IBM, Acer, Samsung, Toshiba, or even a MacBook Pro!

This type of fault can also occur on LCD televisions; however, it tends to be on new units, where the box has received an impact during transit from the factory.

I used this same method of troubleshooting to repair an LCD television recently. Modern televisions have a video out socket, and if you feed the signal from that to another monitor, you can check for the quality of the video display. If the external monitor does not show lines, then you know for sure that it is a connection issue. Hence, this method of troubleshooting works for some of the modern televisions as well.

When half of the vertical interlace is missing showing a picture that is broken up vertically, the display appears with vertical lines. This is usually due to a cracked ribbon cable.

Generally, for laptops a replacement cable is always required due to it breaking near the hinge. I had this Dell laptop and replacing the LCD ribbon cable solved the problem. I managed to buy a replacement from Dell for a modest price £6.00. The laptop was just outside the warranty period; however, they still shipped out the cable free of charge. This is the reason why people buy Dell. In my experience Dell tend to stand by their customers and products, and their prices for replacement parts are realistic and down to earth.

Whether they"re red, green, or blue, vertical lines on a computer monitor aren"t a good sign. Although it could mean your monitor is getting old and may soon need a replacement, it may just be you have a faulty HDMI or DisplayPort cable. Alternatively, it may be your graphics drivers need updating, or you need to restart your monitor or PC.

Vertical lines on a monitor are one of three core problems: the display panel itself is defective, the connection between your computer and the display is faulty, or it"s receiving erroneous information.

There isn"t much you can do about the former unless your monitor is within its warranty period, but the others have some relatively easy fixes which might get rid of the vertical lines on your computer screen.

The first step to getting rid of vertical lines on your monitor is to see if it"s to do with the display itself or some other issue. Open your monitor"s menu system and see if the vertical lines show up even over the top of the menu screen.

If your monitor"s menu isn"t in the right place to test whether the lines are on the screen or to do with the connection, you can also unplug the monitor and see if the lines are still present when it is powered on without anything connected to the display.

The exact cause of the vertical lines on your computer screen will only be apparent if and when you fix it, so it"s best to start trying these examples to see what works.

Update your graphics drivers. If your graphics drivers are outdated, there may be a compatibility issue causing the vertical lines. Update your graphics drivers to see if it resolves the issue.

Try the monitor on another PC. If you can, test the monitor on a different PC. If the lines are still present, the monitor or the cables are to blame and need replacing. However, if you"ve tried all of the above and the lines aren"t there, you may have a problem with your PC itself.

Horizontal lines may indicate overheating, physical damage, or a screen resolution issue. To fix the issue, check the monitor connection and resolution, and remove any magnets nearby. Also, turn the monitor on and off, restart the computer, and connect your computer to a different monitor to test it.

To fix ghosting (screen burn) on a monitor, try shutting down the monitor and leaving it off for 48 hours. Another option: Use an all-white screensaver and let it run on your display for several hours. You can also try a software tool that fixes stuck pixels, such as JScreenFix.

Power down the computer and unplug all peripherals. If you are using a laptop, take its battery out by flipping it upside down and sliding the battery release latch. Press and hold the power button for 15 or 20 seconds to clear all residual power from the system. Some of the computer’s power might have been transmitting to the monitor, causing it to short out. Reconnect everything and turn the system back on to see if the lines are gone.

Unplug the monitor from the back of the computer and wait a few seconds until it displays a message “No signal.” If the no signal message also has vertical lines, you know the problem is in the monitor and not in your computer. Press the “Menu” button on the screen and then use the other buttons to browse for a “Factory Settings” mode. Select this mode to reset the monitor to its original settings. If the lines persist, the monitor may have been dropped or exposed to a magnet -- which can’t be fixed.

Reconnect and turn the computer back on. Look for the lines at boot up: if you see lines before Windows loads, the problem is either with the video card, the video connection cable -- whether HDMI or VGA -- or the monitor itself. If the lines only appear in Windows, the problem is a Windows setting -- most likely the refresh rate. Right-click on the Desktop once Windows loads and choose “Screen Resolution.” Click “Advanced Settings,” “Monitor,” and then lower the refresh rate to see if the lines disappear.

For example, it could signal that the power supply is either failing or faulty. In other cases, it could mean you have not connected the HDMI cable well, or there is a poor connection between the processing board and the panel. But another cause could be the picture does not fit the screen exactly.

When you see black vertical lines on your TV screen, the first step is to identify the primary cause of the problem. Start by testing the picture, check your cable connections, and verify that your external devices are working well.

You can also try changing channels to determine whether the lines appear on all channels. Understand that lines on a TV screen can either be a hardware or software issue.

Ideally, aspect ratio, screen resolution, and horizontal or vertical scan frequencies are settings that affect picture display on most TVs. In this case, refer to the external device’s user manual to adjust the picture format settings.

Your TV software runs the device. An outdated software program can cause many problems like vertical lines, poor picture quality, or failure to install apps.

In some cases, a TV fails to process a combination of image settings you have provided. That can cause many picture errors, including flickering lines on TV. While you can go through all the settings one by one, consider resetting your device.

Sometimes vertical lines on an LCD display could mean a damaged T-Con board. The T-Con or timing control card controls the timing of pixels displayed on the screen. If your T-Con board is faulty, the only solution is to repair or replace it.

If you see Samsung TV vertical black lines on the screen, check whether the lines are permanent or moving. If they are moving, your input source is incorrect. Disconnect and reconnect the video cable or HDMI to check if it resolves the issue.

Thirdly, you may come across a problem with your Samsung Smart TV whereby colored lines appear on the edge of your TV screen. The lines may be black, white, or green along the top, bottom, or side of the screen.

The issue occurs when you have set the picture size of your TV to JustScan or Screen Fit. Samsung calls the lines an Overscan line. If your setting is JustScan, the picture resolution of specific programs will not fill the screen, thus causing the lines.

You can fix a TV screen with lines in different ways. For example, you can change channels to see if the lines appear on all changes, change the input source, check cable connections, or power-cycle your device.

Immediately upon initial installation, it had thin colored vertical lines, about 20-30 lines, in a vertical band about ten inches wide, right in the middle of the screen.

However, the solid black background remained and grew a little wider. The solid black background spans the width of the screen from top to bottom. It is about twenty-two inches wide.

It has a very interesting set of white nearly-horizontal lines which appear at its bottom-most part/border. These lines swirl into a vertex at the right one third of the bottom of the black area. These lines are thin and grayish-white.

Whether they appear as thin or thick, black or white, in the center of your screen or along the border, vertical lines on a TV or computer screen certainly interfere with your viewing experience. Unfortunately, these lines may signify a severe technical problem that"s disrupting the signal between the unit"s processor and its liquid-crystal display, or LCD, screen.

The T-CON board, short for timing control board, is the part of an LCD screen that relays messages between the device"s processor -- it"s brain -- and the display itself. The T-CON board is responsible for synchronizing different parts of the screen with the information it receives from the processor. When the T-CON board fails, the timing between different parts of the board is disrupted, leading to errant lines, both horizontal and vertical, as well as pixelation. The only fix is to have the T-CON board replaced, which generally means replacing the whole LCD screen and usually the entire device with it.

TABs, or tape-automated bondings, are an integral part of any LCD monitor. These bondings digitize the information they receive from the processor and send it to the tiny transistors that create the electrical currents that ultimately affect which colors you see on screen. A TAB fault -- also called a TAB failure -- happens when these bondings are damaged or otherwise disconnected from the processor. When this happens, entire rows or columns of pixels go dark because they aren"t receiving any messages from the processor to create their colors. TABs can usually be reattached by a professional TV repair person but over time may become so loose and so repetitively problematic that they may need to be replaced entirely.

Short for low-voltage differential signaling, LVDS cable systems use twisted copper wires to carry high-performance data. This technology is more energy efficient than earlier electrical systems used in LCD products and can reduce the electricity costs to power the unit. However, when the copper wire that makes up the LVDS is compromised, through either a jolting impact or residual damage, it interferes with the signal it transports from the processor to the LCD screen. As with a T-CON board failure, this results in pixelation as well as vertical and horizontal lines on the screen.

While some vertical lines are the result of damage to your screen, other causes have nothing to do with you, your screen or even how you use it. Instead, the lines may be tied to the video source. Anything that interferes with an Internet, cable or satellite signal, such as an improperly aligned satellite dish or a frayed coaxial cable, has the potential to cause picture distortion, including but not limited to lines on the screen and pixel problems. Even the source itself can transmit images with lines on it; for example, a local TV news station that suffers signal interference during a live shot may broadcast images with lines, pixelation or ghosting.

Back in April last year, Lionel blogged about a vertical line issue that could potentially affect customers who own 17" Inspiron 9200, 9300, and XPS Gen 2 notebook LCDs.

After engaging our engineering and product group teams, as well as the LCD manufacturer, to investigate and isolate the cause of this issue, we narrowed the problem down to a specific part within a certain date range. During that research, we found that the part may also affect the Inspiron 6000, 8600, Latitude D800, D810, and Precision Mobile Workstation M60 and M70 LCDs. That led to Lionel"s second blog post on the topic.

We"ve taken steps to contact those who may be affected to offer a warranty replacement and also put in place measures to rectify any out of pocket expense incurred by out of warranty customers who replaced the affected screens in the past.

That said, there are other variables that can lead to vertical and horizontal lines on other system types regardless of size or model. Lines on an LCD can appear sporadically, at random places on the screen, and for what appears to be for no reason at all. These lines can be caused by normal LCD failures brought on by a multitude of variables, which I"ll try to cover here. Vertical lines tend to be a more common issue in notebooks, primarily because they are subjected to more wear and tear on a daily basis than a desktop LCD.

The most common cause of these lines is simply a loose connection. As notebook systems are carried around, no matter how careful we try to be, they have a tendency to be bumped, jarred, and even sometimes the heart stopping drop. Though today"s notebooks are designed to better absorb and dissipate small shocks, it can still have adverse affects on the notebook"s internal components. A good bump or series of bumps and random movements can cause the LCD cable to become loose. The connection remains intact, but some breaks in the signal can lead to impurities in the reproduction of the image on the screen. Think of a loosely-fastened garden hose… water will still be directed and outputted through the end of the hose, but some water is lost at the connection. This is easily fixed by tightening the hose. Similarly, the LCD can usually be fixed by simply making sure the connection is secure. (Service manuals for Dell systems can be found here on support.dell.com.)

If these simple fixes don"t seem to work, then we need to look at the actual failure possibilities. Vertical or horizontal lines that don"t disappear after the basic troubleshooting are usually caused by circumstantial failures. The most common type of failure that leads to lines on the display is an open circuit connection between the driver IC (flexible circuit board) and LCD glass. This is usually caused by external stresses (mechanical, thermal, etc…), which causes the flex circuit to detach from the glass. The variables leading to the detachment are wide and are dependant on individual cases. With the amount of travel and various operating environments of a notebook, pinpointing the exact cause can be near impossible, unless of course the problem immediately follows a catastrophic event such as dropping the notebook or prolonged exposure to heat or cold, such as leaving the system in a car.

If you are experiencing any problem with lines on your LCD and your system is not one of the potentially affected units, or in the date range outlined in Lionel"s earlier posts, please contact technical support to troubleshoot and identify possible fixes. See below for details on how to do that.

big money for laptops they did not believe to be "B grade". I may not be the most experienced engineer, but if it were my job to R&D issues like this you could bet that this vertical line issue would not have happened. And although I had fun debugging this one, I was not happy with my findings (simple fix / expensive mistake)...

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.

If you are itel, TECNO or Infinix phone user and is troubled with vertical and horizontal line issues, make a reservation now without waiting time at the service shop. Carlcare Service will fix your phones easily. If your phone is under warranty, Carlcare can also save you repair costs. Check warranty now>>

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:

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.

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.

Power down and reboot to confirm that this isn"t a very unlikely issue with video ram or software corruption. Assuming the issue remains this is undoubtedly a screen issue (you could also boot into the BIOS to be sure it"s not software).

It"s also possible that the LCD itself is broken but that is usually accompanied by some signs of physical stress in the form of cracks on the edge of the display or in the plastic around it.
