dark lcd screen problem for sale

I have researched this problem and found that it does indeed indicate that some hardware components may be bad. The following solution seems to be effective in most cases, but it requires very fine soldering skills:

I would recommend using the ifixit guide until you get to the point where they, for some reason, stop short and then refer to the video linked in this kit, then go back to ifixit for reverse install. The video provided technically covers it all (except the front camera and light sensor housings), but is not zoomed in enough to really see what you need to do, even for me having done 15 or so screen replacements in the past for various devices.

However, if the digitizer or LCD is also damaged during a fall, that screen no longer carries value because it cannot be refurbished. Repair shops cannot sell broken LCDs to refurbishing companies; therefore, they cannot offset the cost of an LCD repair. That is why repair stores often charge a little extra if there is damage to the LCD or digitizer, to make up for that loss. Repair stores that don’t have an additional charge for an LCD repair typically inflate their glass repair price to make up for the loss from damaged LCDs. If they have one price, that means everyone is paying more to cover the cost of customers who have damaged LCDs and customers who only have cracked glass. This is why TCR separates the price of glass and LCD repairs for you! If you only have cracked glass, you only have to worry about paying to replace the cracked glass.

If your phone or tablet’s glass is shattered there will be cracks or chips on the screen itself. If it is just the glass that is damaged, the device may still function and you may be able to use it normally. If this is the case, it is likely that only the glass needs to be replaced. To prevent further damage to your device it is best to get it repaired quickly. For example, if liquids seep through the cracks it could cause permanent damage to the LCD.

Many people may continue to use their touchscreen with shattered glass and delay fixing the glass on their devices; however, if the touchscreen isn’t responsive, it could be a sign of more significant damage to the device’s digitizer which is integrated with the LCD screen.

A pixelated screen can indicate LCD damage. This would look like a patch of multicolored dots, a line or lines of discoloration, or a screen with rainbow colors. For many people, these colors are an easy way to know that their LCD is broken and that they should get it repaired.

Dropping your phone isn’t the only reason you’ll end up with a pixelated screen. Over time, your screen’s LCD may break down through regular use. This happens to other devices aside from your smartphone or tablet. Pixelation can happen to TVs and computers, too. People typically decide to buy a new device when this happens. Fortunately, with an LCD repair, you can fix the device without needing to replace it.

A black screen or black spots on your smartphone or tablet is an indication of a damaged LCD. Often with a bad LCD, a phone may still turn on and make noises, but there is no clear picture. This does not necessarily mean any other part of the phone is damaged and a simple screen replacement will get it functioning again. Sometimes it can mean a battery or other internal component is damaged. It is best to have a highly qualified phone repair technician diagnose what is wrong so the appropriate repair can be made.

Fortunately, your mobile device is fixable whether you cracked the glass or damaged the LCD. Stop by or call TCR: Triangle Cellular Repair at (919) 263-2699 for a free diagnostic and quick, affordable cell phone repair in Chapel Hill and surrounding areas. We’re always happy to help!

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.

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.

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 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.

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.

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.

Here we receive a repair case that one of our customers delivered his iPhone with a new LCD screen replaced. The new screen can’t lighten up and he was confused. He contacted the LCD screen after-sale service with no replies. That’s why he came to us since we have cooperated for a lone time. Why does the new replaced iPhone LCD screen dim? Could this problem be fixed? Here we will answer you with the description below.

First of all, we need to know something about the iPhone LCD screen’s composition. The LCD screen consists of eight layers, but only three layers relate closely to the image forming and animation of the screen. The backlight panel is one of the three layers. It is an LED light panel that allows the phone screen to be seen in the dark. When this light panel fails for lighting up, you will see a very dark screen and dim images, which can only seem under strong light. The reasons why this happened are complicated. For one side, some of the low-quality LCD screens are manufactured from third-party factories. These high-copy iPhone screens are not matched with the original screen on the electrical characteristics. The high-copy screen requires much more electric power loss than the original screen. When the backlight circuit is overloaded, it would be damaged and not working. On the other side, some physical damages to the iPhone screen may also cause the screen backlight panel to fail for lighting up after the iPhone LCD screen replacement.

Fixing the iPhone LCD screen backlight circuit issue is very complicated. It requires someone very professional on iPhone repair. Since the backlight failed for lightening could be many reasons, the repair solutions consist of a simple filter replacement, another can require replacing the whole circuit or adding jumper wires to bypass damaged IC tracks. Details of the repair process refer to the tutorial presentation video on YouTube or Google. Watch these videos if you are interests. We advise you not to try if you are not experienced enough under no professional guidance because it is risky. Inexperienced operations may cause irreversible damages to the new screen. You may also check our iPhone repair guidance videos on our YouTube channel if you have interests.

We suggest our customers choose the highest quality level iPhone LCD screen for replacement. The original new iPhone OLED screen and digitizer would be better but it cost much higher in price. Don’t trust any “parts swapping fixing everything” from the third-party repair shops. Choose the original new LCD screens or high-quality level screens for replacement if you have to swap your original screen. No matter what, we should take action for our iPhone screen’s protection, or else it will cost us a lot on repair. Applying a screen protector is a good way to keep our iPhone screen from damage. A protective shell will be better as long as you choose the suitable size for your iPhone.

Now we have explained how does the iPhone LCD screen dim problem occurred, and how to fix the issue in the description above as well. We hope our customers will take our advice to get away from this issue because fixing the iPhone screen will cost us a lot of money. Besides, you may also watch our iPhone screen replacement guidance video on our YouTube channel. Also, you can come to our shop for iPhone 11 high-quality LCD screen and digitizer, and other swappable parts if you are interested. For any questions about iPhone repair, please leave your comments or contact us via email. We are glad to help.

Does your iPhone screen keep going black? If so, you’ll need to figure out what the problem is, since you won’t be able to use the device’s most vital functions until you do. An iPhone’s screen going black is usually the result of a hardware problem rather than a software one. In the article that follows, we will run through all of the possibilities, though, and explain what you need to do about each of them.

The first thing you can attempt if your device’s screen is going black is a hard reset. To do it, press the Power button, also known as the Sleep/Wake button. At the same time, press the Homebutton, the circular button directly below the display. Hold them both for a minimum of 10 seconds. You’ll know that you’ve executed the reset when the Apple shows up on the screen. This works if you have an iPhone model 6 or below.

If the Apple logo shows up on the screen, it will be a relief, in a sense. It means that the screen is going black because of a software crash, and probably the hard reset will fix the problem. If you don’t see the Apple logo, though, or it seems as though your device can’t be reset this way, it’s not exactly good news. This is a reliable indicator that the problem has to do with the iPhone’s hardware.

To comprehend what elements might cause your iPhone’s screen to go black, you need to understand a little about how the device is put together. The logic board could be considered the brains behind the operation of the iPhone. Essentially, every part of your iPhone is connected to it. The display shows you the images, but it is the logic board that dictates what is displayed.

The iPhone’s display is made up of four components. There’s the Home button and front-facing camera. There’s the digitizer, which is the aspect of the phone that processes touch as you run your finger over it. Finally, there’s the LCD screen, which is the external part of the phone where you see the images displayed.

Each of these components has a separate connector that plugs into the device’s logic board. That is why, even if your screen keeps going black, you might be able to swipe across the screen with your finger. The digitizer still works in that scenario, but the LCD does not.

In a lot of these cases, your screen is going black because the cable that serves as a connector between the logic board and the LCD has become dislodged. This is the display data connector cable. It can be disconnected sometimes by your iPhone being dropped, shaken, or otherwise roughly handled. That’s why you should think about whether anything has happened to the device recently if you’re trying to figure out whether a hardware problem is to blame.

If the display data connector cable has become disconnected, but none of the other components have been damaged, it’s a relatively easy fix. All that has to happen is for someone knowledgeable to remove the LCD display and reattach the cable. However, we don’t recommend that you try this. If your phone is under factory warranty, then taking it apart and trying to fix it could void the warranty.

Another thing that frequently happens with iPhone’s is them getting wet. If that’s what happened to your device, then probably the reason that the screen is going black is that the moisture has ruined the electronic components of the LCD screen. Exposure to liquid can prove fatal to this part of the phone.

Again, the best option is going to be the Apple Store and the Genius Bar. If your phone is not under warranty, this is going to be a more costly fix, since the LCD screen will have to be replaced rather than merely a cable being reattached.

It’s also worth mentioning that you can take your iPhone to a third-party repair person or store if you’ve gone to the Apple Store and found out that the LCD screen needs to be replaced. Since these sorts of repairs can be costly, seeking help from a non-licensed electronic repair person might be tempting.

Ask them before you hand over the phone whether they’ve had experience with this sort of problem in the past. In addition, make sure that the replacement elements that they use are real Apple replacements rather than third-party knockoffs. Finally, be sure that they check with you to get confirmation that the cost of repairs is okay before they go ahead and do it. In certain cases, it makes more sense to sell your old iPhone and upgrade to a new one (vs. paying for expensive repairs). You can easily check the value of your current iPhone using the links below:

Ever had your TV showing nothing but a black screen even if the audio was working? Unfortunately, that’s a common issue with low/middle-end LCD/LED TVs these days… Even more frustrating, this issue often comes from a rather tiny and cheap component that can be easily replaced. Most common issues are:

One of my relatives had this exact symptom happening all of a sudden. This problem on low-end TVs often occurs within the first couple years. As the repair costs for that kind of TV is pretty low, considering repairing it yourself might be a good idea!

The first step into repair is to find the root cause of the issue. As backlight failure is a very common issue, this is the first thing to test. To do so, the easiest way is to power on your screen, put a flashlight very close to it and check if you can see the image through. The image would be very dark, like turning the brightness of the screen very very low.

That implies disassembling the TV to access the backlight which is between the LCD screen in the front and the boards in the rear. In my case, with a Samsung F5000, I had to process as follows:

First we have to remove the back housing to reveal the boards (from left to right: main board, T-CON, power supply) and disconnect the LCD panel from the T-CON board.

Note: Older TVs have neon tubes for backlight, which is thicker and less exposed to this kind of failure. LED backlight is the most common thing these days, but do not mistake an LED TV with an OLED TV. The first one is a classic LCD panel with a LED backlight, whereas the second is an OLED panel that doesn’t need any backlight as it is integrated in each pixels (making the spare parts much more expensive by the way).

As we can see, the backlight system is made of 5 LED strips. First thing to do is look for burnt LEDs. Most LED backlight systems have strips set in series, meaning that if one of the them fails, all the system goes dark…

For starters I’ll go with the third one, just to make sure there is no other issues with the TV, but afterwards it’s better to replace the LED with a new one, otherwise you might notice a darker spot on the image.

There might be a lot of other root causes for similar symptoms, a black screen often looks like something very serious and therefore expensive to repair, but this case is the perfect example that taking some time to look for the root cause can sometime lead to a good surprise: here a 1$ fix!

A black screen on an Android can be frustrating. If you can tell your Android phone is on, but the screen is black and won"t respond, there are a few things you can do that might get it working again.

Wait until the batteries die completely and the phone shuts down and then recharge the phone, and restart it after it"s fully charged. If there is a critical system error causing the black screen, this should get your phone working again.

Gently, but firmly press your phone from both sides, squeezing the front and back together. If there"s a loose LCD connection, this could help reseat the connection and get the screen working again. If this works, consider taking the phone to an authorized service center to have them firmly reseat the LCD cable.

If your phone is in a case, remove it from the case before you start this process so that you can accurately gauge how much pressure to put on your phone without breaking the screen.

Plug in phone, wait five minutes, and then try to do a Force Restart. This ensure the phone has enough power to restart, and restarting could clear any errors that might be affecting the screen.

If you have one, remove the stylus and see if it causes the screen to come on. If it does, navigate to Settings > General management > Reset and then choose Auto Restart and schedule a time for your phone to restart. You"ll have to wait until this time to see if an automatic restart fixes your problem.

Alternatively, you could also choose Factory data reset from the screen to completely reset your phone back to factory specs. This can be useful if you"ve installed a corrupt app that is affecting your display.

Reboot your phone into Safe mode. Safe mode may allow you to navigate the phone to restart it, clear the cache (more on that below), or perform other tasks that could help fix the black screen problem.
