black line on lcd screen manufacturer

That looks like a problem with the actual lcd panel (ie. the physical screen). I assume those blacks marks stay exactly the same no matter what is on the screen (IE. while loading Windows, logging in, on desktop, etc)?

The answer would be to have the screen replaced - this is a simple job for a repair shop to do for most laptops. Doesn"t usually cost too much either.

Could be a couple of different things. First I would guess that the ribbons that connect to your tv are loose. They are usually held together by just glue. You could maybe try re gluing it, or putting a temporary fix with some tape. First u will need to remove the panel to the back of your tv. Before you do anything, try to put some pressure on it and see if the lines go away. I have also seen lines on tvs from someone dropping them, hitting them etc. any pressure on the screen can sometimes cause this. If thats the case, unfortunately it would be better to buy a new tv verus how much it would cost to fix it. If u do go the route of buying a TV used or new, i highly recommended doing a little research on the brand and model of it. I personally have had bad luck with Element. But have had good luck with samsung, sony, and Vizio. Good luck to you.

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.

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.

Since then, comments have hit our forums and blog site about other potentially affected systems and possible causes and fixes for them. We"ve gone back to our engineering and product group teams and verified that the part causing this issue:

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.)

A golden rule of any seasoned technician when it comes to cable connections: don"t just check the connection, reseat it. This applies to more then just cable connections (memory, wireless cards, hard drives, optical drives, etc…) There are a few reasons for this, the first being temperature. With so many components designed into such a small case, heat is inevitable. These temperature variations can lead to things like "chip creep" and oxidation. Removing the cable and firmly, but carefully reseating it should solve this problem by not only making sure that the connection is properly seated, but also that the pins are free from oxidation.

The second reason is debris. If you"ve ever opened up your notebook to clean the keyboard or for maintenance, you might see any number of things such as food particles, hair, paper, dirt and dust. Some of these objects are small enough to get into the connections and cause problems. This is one of the reasons that regular cleaning of your notebook and desktop PCs should be done. The problems caused by debris can usually be quickly cleared up by a can of compressed air and a little time and effort.

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.

Investigations into technical problems, including which systems, batches, and date ranges are affected, are rigorous, and we strive for accuracy. Unfortunately, not every technical problem can be traced down to the root cause. But in every case, we try to proceed appropriately and in all fairness to affected customers.

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.

Dell recommends ensuring that the device drivers and BIOS are up to date using the SupportAssist application for optimal video performance and to help resolve common video-related issues.

NOTE: When SupportAssist does not show up in the search results, go to the SupportAssist for PCs and tablets page for information about downloading and installing SupportAssist.

To learn how to manually download and install a device driver such as Chipset, Video card (GPU), and Monitor driver (if required, most monitor drivers are delivered automatically through Windows Update) on your Dell computer, see the Dell knowledge base article How to Download and Install Dell Drivers.

We must verify whether the problem is the display screen of the laptop, video card (GPU), or video settings on the computer. A straightforward way to identify this is to connect the laptop to an external monitor or TV.

If the issue persists on the external monitor, it may be an issue with the video card (GPU) or video settings and not the laptop LCD panel. Go to verify display or video issues in Windows Safe Mode. Otherwise, go to the next step.

Performance issues may occur if there is any damage to the LCD screen. The display may stop working, work intermittently, flicker, display horizontal or vertical lines, and so on, if there is damage to the display screen.

If you notice a physical damage, contact Dell Technical Support to learn more about repair options that are available in your region. If there is no damage, go to the next step.

Dell laptops have integrated diagnostic tools that can determine if the screen abnormality is an inherent problem with the LCD screen of the Dell laptop or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry images, horizontal or vertical lines, color fade, running a diagnostic test on the LCD helps identify if the issue is with the LCD panel.

Press and hold the D key and turn on the computer to enter the LCD built-in self-test (BIST) mode. Continue to hold the D key until you see the entire screen change colors.

If you do not detect any screen abnormalities in the integrated self-test mode, the LCD panel of the laptop is functioning properly. Go to the Update the video card (GPU) driver, monitor driver, and BIOS section.

If you notice any abnormalities in the LCD built-in self-test mode, contact Dell Technical Support to learn more about repair options that are available in your region.

Windows Safe Mode does not load any drivers, startup applications, third-party services. This will help us identify if the issue is related to the operating system, video settings, device drivers, or third-party software. To learn how to boot your computer into Safe Mode, see the Dell knowledge base article below based on the operating system that is installed on the computer:

Windows updates can support your Windows operating system in many ways. Windows updates can solve specific problems, provide security patches and protection from malicious attacks, or even add new features to the operating system.

Display settings like brightness, refresh rate, resolution, and power management may affect the performance of the LCD screen on your Dell laptop. Changing or adjusting the display settings can help resolve several types of video issues.

NOTE: Depending on the model of the Dell laptop, the shortcut keys to adjust or change the brightness may differ. See the User Guide or User Manual of your Dell laptop for model-specific information.

If you find that the Dell laptop is unresponsive to touch, touch stops working entirely, or other touch-related issues, you can try some common troubleshooting steps to help fix the touch-related issue.

Stress Test can thoroughly diagnose the video card (GPU) on your computer and report any potential hardware problem. Running a stress test on your computer can verify if the hardware components are stable and thus reliable.

System Restore is an integrated Windows tool that is designed to protect and repair the operating system. When something goes wrong with your computer, System Restore must be used before you try to restore the operating system to factory default settings.

If the diagnostic tests on the LCD panel and the video card (GPU) passed, it is most definitely an issue that is related to software that is installed on the computer. If the above troubleshooting steps did not resolve the issue, you may try to restore the computer to factory default settings as a last resort.

WARNING: Restoring or resetting the computer to factory default settings will erase all personal data on the computer. Back up all important data like documents, images, music files, spreadsheets, videos to an external hard drive or a cloud-based backup like Microsoft OneDrive.

Dell computers are built with a small amount of hard disk space that is reserved for reinstalling the operating system. This method is the easiest way to restore the computer to factory condition. The restoration process deletes all user data from the computer, so be sure to back up all your files before starting this process.

Once you have found the correct part number, see HP Consumer Notebook PCs - Ordering HP certified replacement parts. Use the instructions in this document to order a replacement part.

HP recommends that you only order parts from an authorized HP repair parts dealer. Parts ordered from third-party companies might not perform as expected and might cause additional

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.

Eight black lines or bars appearing on the LCD indicate that the machine is in the firmware installation mode. This may be accompanied by intermittent beeping.

$NOTE:The machine will be in this mode because either the 5 key was pressed/stuck when the machine was powered on or a firmware update was interrupted before completion.

5. If the black lines still appear on the LCD, the firmware has been corrupted. This occurs as a result of interrupting a firmware update. This cannot be corrected by troubleshooting, but the situation can be quickly resolved by an Authorized Service Center (ASC). The repair cost for this issue will be covered by Brother.

If you have a black line that is more than .5 cm in width you can try this. LCD monitors, stand alone or those on laptop or notebook pc have a flexible cable that runs from the logic board to the back of the LCD panel thru a snap-on connector. It is held mechanically by the connector on the lcd and a self-adhesive taped to the lcd. Because of thermal cycle (cold-hot)there is a big chance that this connectors will loose contact. What I have been doing is to peel off carefully the adhesive tape (emphasize on carefully) then take off the connector by unlocking the levers on the connector on the lcd side and the flex cable would come off. Get some cotton buds(ear buds or cotton swab) dipped in denatured alcohol or any light contact cleaning agent and lighty wipe the contacts on the flex cable. Let it dry, plug back the cable. Get fresh adhesive tape, add another layer on top of that just to make sure it won"t move this time. Test, 80% of the time I do this, it works.
