lcd panel has a line accross it in stock

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.

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?

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.)

Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.

Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (Retina 5K, 27-inch, 2019) has a display resolution of 5120 x 2880, which means there are over 14.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 44 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.

In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.

If you are concerned about pixel anomalies on your display, take your Apple product in for closer examination at an Apple Store, Apple Authorized Service Provider, or an Independent Repair Provider. There may be a charge for the evaluation. Genuine Apple parts are also available for out-of-warranty repairs through Self Service Repair.*

Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

Sony produces and sells commercial MicroLED displays called CLEDIS (Crystal-LED Integrated Displays, also called Canvas-LED) in small quantities.video walls.

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

As often as you use your smartphone, it’s almost inevitable that you’ll eventually drop it. You may be extremely careful, but it only takes one fumble for your phone to tumble. While iPhone screens are designed to withstand impact, you might still end up with a shattered screen.

The good news: a broken screen doesn’t mean your phone is kaput. In fact, if only the glass is broken, the fix is quick and inexpensive. The bad news: if the LCD screen is broken, you’re looking at a pricier repair.

If you’ve looked into replacement parts, you’ve likely come across two very different options: a glass screen, and an LCD screen. While the first option is cheap, the second is definitely not. Here’s the difference:

1. The glass screen is the exterior layer on your phone’s display. While it is specially engineered for durability, it’s still just glass (between layers of plastic film), which is why it’s not very pricey to replace.

Most of the time, the damage to your screen will be pretty obvious. You’ll see the spider web patterns of shattered glass across the front of your iPhone. Occasionally, however, the glass screen will be intact, and you might not realize the damage until you try to use it. Whether the damage is visible or not, it’s a good idea to run a quick diagnostic to determine the extent of it.

If you encounter any of these problems, you’re dealing with a broken LCD screen. If the glass is shattered, but the display is clear and touch capability is working, that’s a good sign. The problem is probably just the glass screen.

Whether you’re dealing with cracked glass or a broken LCD screen, you can find a quick, reliable repair service at FastPhoneRepair.com. Our qualified technicians will get your iPhone repaired and up and running again in record time and at reasonable rates.

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.

Hey there Andrew - okay, here’s an update, as requested. There’s quite a bit of info I’m sharing here, because I couldn’t find it ANYWHERE on the internet. It took LOTS of research to figure it out.

I ended up diagnosing the problem as a faulty connection between the ribbon and PCB gold leads, if that description makes any sense. By squeezing the gold leads with my fingers, I was able to get the lines to go away. Now for an embarrassing admission: I attempted to just barely heat up the leads to solidify their connection to the PCB, and I almost instantly melted the ribbon cable. I had the PCB taped off with painter’s tape, but I didn’t realize that the plastic ribbon is also connected to the gold leads (duh!). I did all of this with the unit powered on, and instantly blew the fuse in the power supply. I’m sharing this so all of the other newbies can learn from me and avoid this idiotic mistake. Here’s the replacement fuse for the power supply that I bought, and it’s working well:

Pack of 5-2.5A Glass Fuse (GMA), 250v, 5mm x 20mm (3/16" X 3/4") Fast Blow (Fast Acting) https://www.amazon.com/dp/B074HFG2P6/ref=cm_sw_r_cp_api_i_4scKEbDAD8S1Z

I still have an interest in building an updated LED display, and I was able to find out from an obscure Russian forum (thanks to Google Translate) that the display is driven by 2 Epson SED1565 drivers/controllers, those 2 little rectangular chips on the ribbon. Just a random piece of info for you.

But, until that awesome day of discovery, I caved and just bought a beautiful used display pulled from a Korg Triton LE from eBay (would have gladly purchased from Syntaur if it had been in stock). It works perfectly. I pulled the glass display out of the black plastic casing and gently inserted it into the Karma’s original white plastic casing. The LED lighting on the Korg Triton LE comes from a single bulb that is dispersed by the design of that black casing. The Korg Karma is much better as it has around 40 small amber colored LED’s on a PCB that light up the display quite evenly. Just know that there’s a little more to it than just plugging in a new display if your new display does not come from a Karma.

I had purchased new pots for the joystick, but found that DeOxit d5 spray fixed up the originals perfectly for me. Nonetheless, the pots I bought look exactly like the originals. All of the knobs on the Karma use these.

The joystick and knobs were very stiff, and several of the buttons required a bit of pressure to get them to respond. I took the entire keyboard apart and sprayed DeOxit d5 (BIG SHOUT OUT TO SAM MIMS!!!) in all of the knobs, buttons, and the joystick potentiometers to get them working again.

All in all, this keyboard plays like a dream, and far better than it did when I first got it. And… the best part is that I got this synth for free, long story. I am thankful to have a keyboard that is FULL of nostalgia for me!!! Here are some pictures of the final product.

I cannot thank Sam Mims enough! I watched all of his videos restoring synths and they motivated me to try it out. It was a basic part swap out and a failed screen repair, but I still came out ahead, so I’m happy. I learned A LOT through the experience. And I read that Sam played keys for Richard Elliot. I’m a sax player and used to listen to his CD’s all the time in high school. So cool.

The types of targeting available for YouTube & partners line items are slightly different than Display & Video 360"s standard set of targeting controls. Additionally, unlike other types of line items, targeting for YouTube & partners line items is set at three levels: the advertiser, line item level, and the ad group level. Targeting set at the insertion order level doesn"t apply to YouTube & partners line items.

Targeting set at the line item level will apply to all ad groups contained within the line item and can"t be overwritten by ad group targeting. Usually people use line item targeting to apply general targeting to their YouTube ads.

Include video partners: A collection of partner sites and apps that follow the same brand safety standards as YouTube. Learn more about Google video partners.

You can choose to exclude individual keywords or a negative keyword list at the line-item level. The same keyword matches described below are available for individual keyword exclusions. Learn more

Category exclusion settings - content categories, digital content labels, and other content types - help you exclude types of content that, while in compliance with our policies, may not fit your brand or business. Regardless of the settings you select, your ads will be excluded from showing on content that isn’t appropriate for any advertiser. Learn more

Show your ads based on the languages a user speaks. This is determined based on the language preference a given user sets on the YouTube homepage, as well as various other signals such as the user’s browser language, location, and viewing history.

Depending on your video ad format, you can show video ads based on words or phrases--keywords--related to a YouTube video, YouTube channel, or type of website that your audience is interested in. You can use the following keyword matches to control which searches will trigger your ad:

Target your video ads to specific topics on YouTube and from video partners. Category targeting lets you reach a broad range of videos, channels, and websites related to the topics you select. For example, if you target the "Automotive" topic, your ad will show on YouTube to people watching videos about cars. Some content subcategories can"t be excluded from targeting.

Video lineups: Select this option to target popular content and video lineups across YouTube and Google video partners. You can include popular content and lineups but can"t exclude them.

Apps:Select this option to target individual apps for Android and iOS app stores. You can search for apps by name or app store ID. To search for apps by operating system, use the platform filter.

Collections: Select this option to target dynamic groups of related apps. For example, a collection called “Top selling free weather apps” will always be up to date. There’s no need to track the top weather apps or manually add channels to target them. You can filter the list of collections by platform and search for specific collections. You can also click “Included apps” link for each collection to see the list of specific apps included in the collection.

To add placements in bulk, select the option to add multiple items at once. Enter a list of app IDs and URLs, one item per line. Make sure you use the following formats:

Keep in mind that when you add YouTube placements, your ads may still run in eligible locations across video partners. Similarly, when adding video partner placements, your ads may still run in eligible locations on YouTube. If you"d like to target only one specific placement, make sure that your line item"s inventory source targeting excludes all other content. For example, if you want to only target a specific YouTube placement, exclude video partner placements from the line item targeting.

If you exclude a placement at the advertiser level as described above, you cannot override that setting by including the placement at the ad group level.

YouTube audiences: Reach viewers that are important to your business with first-party audiences. You can target YouTube users who have interacted with your videos or YouTube channel, or upload Customer Match lists. Learn more

Affinity: Raise brand awareness and drive consideration with your YouTube video ads by reaching people who already have a strong interest in relevant topics or based on their shopping and lifestyle habits, such as where they shop or how often they go out to eat. Learn more

How long will your LED display last? In nearly every industry, from retail businesses to concert halls to corporate centers, decision makers need to evaluate the return on investment (ROI) of their LED signage. In most cases, potential buyers go straight to the obvious place: the LED manufacturer’s spec sheet. The industry standard for LED lifespan is 100,000 hours, or about 10 years, and most people assume that’s how long their display will last. But it’s not quite that simple.

The 100,000-hour figure assumes that every diode will be running at full brightness, consistently — which, on an LED screen, is virtually never the case. The lifespan figure can also be misleading because it indicates when a diode degrades to half-brightness, not completely dark. Many other variables affect an LED display’s lifespan; you can’t rely solely on the number on the diode spec sheet.

“The reality is, your screen can often last significantly longer than 100,000 hours,” says Kevin Izatt, a senior product manager in Samsung’s Display division. “We’ve had displays that have been up for 15-plus years with more than adequate brightness. Because the diode is actually only one factor in the lifespan of your LED display.”

The biggest contributor to diode degradation is heat. As you increase a diode’s brightness, it produces more heat. Your display’s physical environment also contributes to the temperature of the diodes, especially for outdoor displays.

“Let’s say you’re in Vegas — Death Valley. The diode is fine to operate at those temperatures, but it will degrade faster,” says Izatt. “Temperature is a big factor — and not one you have control over.”

The quality of your display’s power supply — and how hard it drives the diodes — can have a significant impact on your screen’s lifespan. The other components being powered, such as fans and electrical components, have their own lifespans as well, which are also impacted by the power supply.

“Fans are mechanical; they break down,” explains Izatt. “And similar to your computer, the electrical components don’t last forever. Together, these factors all contribute to the lifespan of an LED display. Looking at just the diode lifespan doesn’t give you the complete story — almost always, another part will go out first.”

“Something like airflow is very important,” says Izatt. “You need a screen that has good cooling, and a design that allows heat to flow out of the back through vents.”

It’s easy to see why: The circuit boards powering the display release heat, and that heat needs to go somewhere. Without a strong design, thermal stress will degrade the life of the display, except for the highest-quality parts — optimal conditions notwithstanding.

“Lots of variations on the color and brightness you use will impact the life of the diode,” explains Izatt. “For instance, black doesn’t use any of the diodes at all. And if your content is using lots of gray, that’s a much lower power output than white.”

That’s not to say you should hold back on displaying rich, vibrant colors — after all, that’s what LED does best. But it does factor into your product’s life expectancy.

To help businesses transition from LCD to longer-lasting LED signage, Samsung has launched a trade-in program. Samsung will come on site to remove your existing display and provide a discount on a new LED bundle kit.

Traded-in LCD displays that are still operating will be refurbished and resold, and your business will receive a cash rebate. Nonworking displays will be recycled and their parts reused.

You can’t rely on the number on the diode spec sheet; the lifespan of your LED display depends on many more factors. “Overall quality has a tremendous impact on the life of the display that diode specs just don’t take into account,” says Izatt. Your best bet is to look at the purchase holistically and invest in a top-tier product.

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.
