The wiring connections to the screen would have to match between the old display and the new. By that I mean that the wires coming from the system board would have to perform the same functions when connected to the same points on the new display. For this you would have to know the internal wiring details of both the old and the new display panels. It would also have to have the same type of cable connector as well.

One way that might possibly work is to open the phone and see if there is a part number printed on the back of the LCD panel itself. Using just the number try searching online to see if you get results.

Most LCD panels be it for TV, Monitors , Phones etc., are made by specialist LCD panel manufacturers who make to order for the device manufacturer. Also don"t be surprised that even if you find the manufacturer that you will not be able to purchase it directly from them.

You could also search places like Ebay etc where your particular model phone may be offered for sale as faulty good for parts where it appears that the LCD screen is undamaged and possibly still working but cannot verify as the phone doesn"t work at all. You could always contact the seller and ask was it working before the phone failed, was the phone dropped etc., and hope for honest answers. Then it depends on how much you are prepared to gamble, money wise, hoping that the LCD is at least OK, so that you can swap it over.

If you have two identical phones, one with a faulty screen and the other with a working screen but not working otherwise then you could swap the good into the faulty but to re-purpose it between different brands or even different models you would have to know its" input wiring connections so that it would be suitable to use somewhere else.

As you can see from the schematic (scroll down a bit) in the link below the example shows the LCD having 16 input leads. There is no standard as to what function goes onto what input as the LCD manufacturer would make to order from the device manufacturer to suit whatever particular requirements.

The best that I can suggest is that you offer it for sale (or for free) as faulty -good for parts, LCD works on places such as Ebay, Gumtree, etc. to minimize the amount going to landfill. You might be surprised at the response as usually the major problem with devices is a broken screen which is hard to source, especially on the lesser known brands. So if it is re -usable by someone else you have minimized, as best you can, the amount going to landfill (the other phone is repaired instead of replaced, again with less landfill and your phone has less parts being sent to landfill by the new owner - basically one completely faulty phone being sent instead of two partially faulty), and also perhaps you have recouped a little cash towards the purchase of a new phone.

Maybe your significant other tossed your phone off the balcony after discovering flirty texts with a certain coworker, or maybe you were just blackout drunk and dropped your phone on the club’s tile washroom floor while taking a shameless mirror selfie. Either way, your mobile’s glass screen likely looks like a drunken spider’s web.

Luckily for you, smartphone repairs in China are both affordable and fast. But before you venture off to your city’s electronics sales and repair market, we encourage you to browse these six helpful tips for repairing your phone screen:

As with damage to just about any electronic product, knowing the extent of the destruction will go a long way towards ensuring your trusty repairman doesn’t try and pull a fast one by over-quoting or overstating the damage.

In the case of phone glass and the LCD – or more recently AMOLED – screen underneath, it helps to know whether just one, or both, of these elements needs replacing (particularly so you can better estimate the cost).

While broken glass on the front of your mobile is obvious and easy to diagnose, a damaged screen (the part that actually displays all the programs and interface) can be a bit trickier to identify. Look for black spots, discolored areas, new lines and out-of-place patterns on your screen, as any of these may indicate a problem with the screen. Naturally, a totally black screen is a pretty good indicator that something is amiss.

One way to test your screen is to hold down on an app on your phone’s ‘desktop area’ until it starts vibrating, allowing you the move the app to new locations on your screen. Move the app to all parts of your display, if the app is unable to reach a certain area, this is a good indication that you’ll be fixing more than just broken glass.

From our experience, this may very likely be the most important step of all. When having your device"s screen or glass fixed, be sure to show the person doing the repair that all of its key components are in working order. In particular, be sure to demonstrate that both your front and rear cameras work, as well as the speaker and microphone.

We cannot count how many times we have heard of a phone being returned after a repair only for the owner to discover that the phone’s microphone (key for, you know, speaking on the phone) or cameras are no longer working. Also from experience: most repair people are unlikely to take your word that your camera was fine before you handed it over to them.

This should probably go without saying, but here we go anyway: having your mobile device repaired by someone other than a company technician from your phone’s particular brand will likely (like basically 100 percent) result in your warranty being voided.

Not every repair shop will give you the option of watching your phone’s crushed glass be replaced. This is because many smaller shops, particularly in electronics markets, will have your phone sent to an offsite repair area and tell you to come back in a few hours to collect it.

If possible, try and find a shop that will complete the repair in front of you. The main reason we encourage this is because we have heard several unfortunate stories where costumers have had their fully-functioning phone battery swapped out for one that can only hold a two-hour charge. Sad!

The price of having your phone’s glass or LCD screen replaced will depend greatly on the make and model of your phone, the honesty of the person fixing it and – like all things in Asia – your bargaining skills. If your local smartphone repair person wants RMB300 to replace your iPhone 6’s shattered glass, lowball them and offer RMB150. From our experience, repair people seem more inclined to budge on price when it comes to older model phones, meaning your brand new iPhone Xs Plus or Huawei P20 will likely have a higher price point and less discount wiggle-room.

Finding a good repair shop with honest staff who do repairs at a high quality and reasonable price can sometimes be difficult. If you manage to track down a good phone-fixing location, be sure to recommend it to your friends to save them the potentially costly and annoying trial-and-error process when having their glass or screen replaced.

Lately, there have been complaints from Samsung users about their device screen going black without giving any sign. Well, this error is usually a result of crashed system, outdated Android version, drained battery, etc.

Anyway, there are several ways you can get rid of the Samsung black screen of death issue without requiring any technical knowledge. Yes, in this article, we"ve discussed 11 different simple solutions you can employ to fix the Samsung phone"s black screen.

A system crash might occur for numerous reasons, like insufficient storage, incompatible apps, and more. And most of the time, the crashed system could result in the Samsung phone suddenly going black screen.

Insufficient storage can lead to a system crash. However, sometimes, when the Samsung device has insufficient storage, it could simply stop responding, thus, causing the screen to become unresponsive, and often go dark.

If you do not update your Android version for a long time, there is a good chance that the system might become unresponsive. For instance, Google no longer supports Android 7.0 Nougat.

Sometimes, buttons of the Samsung device may be jammed, thus, causing your device to experience a black screen of death. If that is the case, ensure to unjam the buttons of the Samsung phone and try again. Once the button starts responding, reboot the device to get the device working again.

If your Samsung device"s charging port is filled with liquid or dirt, then chances are it won"t charge properly, thus causing a black screen error to occur.  In this case, we recommend cleaning the phone charging pot and leaving it to dry perfectly.

A solution for Samsung devices with removable batteries only!  You can deal with the black screen on Samsung phones by simply removing the battery for 1 minute and then reinserting it. There is a good chance that your screen will work again.

SD cards can be incompatible with the Samsung device most of the time, especially if you are not utilizing a Samsung SD card. To review whether the SD card causes the black screen on the Samsung phone, simply remove the card. Shut down the device and restart it again.

If your Samsung device has a non-removable battery, you can wait until the batteries die completely and then charge it again. Most of the time, software problems cause the Samsung Galaxy black screen of death issue. And a simple reboot after the batteries die entirely could effectively restore your device to a normal state after the restart.

A soft reset is nothing but simply turning off the Samsung phone and restarting it using the power button. Ensure to charge the Samsung device before you perform a soft reset.

To soft reset, you can try pressing the power button and volume down button simultaneously for more than seven seconds. This may restart the device and get the screen to a normal state again.

Another primary cause for the Samsung Galaxy phone displaying a black screen is the loose or improper LCD connections. To rectify the issue, you can remove the back cover of the Samsung phone and gently press the Samsung phone on all sides while pressing the front and back together. If the poor LCD connection is the cause, this method should get the phone working again. Additionally, you can take the Samsung device to an authorized repair shop to reset the connections properly and avoid future mishaps.

You can fix the Samsung black screen issue by rebooting your device into safe mode. What this does is, it returns all settings on your Samsung device to default. Thus, enabling you to detect if an installed app is causing your phone to display a black screen, freeze, or perform operations slowly.

There is a good chance that some incompatible apps may have messed up with the software, which resulted in the Samsung phone"s black screen of death. So, you can opt for Factory Reset remotely via Find my device.

Of course, if all these methods do not work, contact the Samsung support center. Better yet, visit the nearest service center and let the professionals repair the phone for you. A door service is also available, which you can book from the official Samsung device.

With methods mentioned above, you can fix the black screen issue of your samsung now. However,to avoid data loss when you encounter issues like the black screen on a Samsung phone in the future, ensure to backup the device regularly. Since the discontinuation of services like Samsung cloud for media, it"s becoming difficult for users to backup the contents on Samsung devices. Nevertheless, you could utilize third-party applications like MobileTrans and backup your Samsung device with a click.

Step 3.Once you click on the Start option, MobileTrans will start restoring the selected file types on the Samsung device. You can also tick the Clear data before copy option, which will erase the chosen files after restoring them to your Samsung device.

Samsung phone black screen issues are not common, but they can happen. And as mentioned already, the Samsung phone"s black screen of death is often caused by small issues like incompatible apps and insufficient storage. And a simple reset or one of the solutions mentioned in this guide can effectively get the screen working again. However, it is critical to note that sometimes the cause can be significant. And you may have to perform a Factory reset to deal with the black screen on a Samsung phone. That is why it is essential to backup your Samsung device regularly using the best tools like MobileTrans. As mentioned, you can also restore the backups efficiently using MobileTrans.

Since there are some differences in quality between the China-made iPhone screens and original iPhone screens, so you need to be careful when handling the new iPhone screen replacement, according to our test, the top corner of the screen is one of the key parts that should be gently treated. Don’t push these 2 corners with force when reassemble the phone.

After installing front camera and ear speaker, you’ll need to hold them with the metal bracket, there is another point you need to be carefully dealing with, please note that all the screws have unique positions, don’t mix them with wrong position, and what needs to be paid more attention to is the rightmost one with a red circle showed below, do not twist this screw too tight, or which can somehow cause the screen cracked after reassembling the screen.

After connecting the screen connectors, then you may need to test the screen functionality before totally installed. You’d better make the angle between the screen and body is less than 45 degree during the screen test. With screen test finished, then the last step, make sure the screen replacement is properly aligned with the housing edge.

Today, many of us rely on our smartphones to communicate, work, and play. Therefore, it can be quite alarming when they begin to act strangely – especially if you can’t get your phone to turn on at all.

One of the most concerning issues to plague smartphone users is a black screen, often referred to as the “black screen of death.” However, despite the harsh name, this issue can be remedied in several ways.

To fix a black screen on an iPhone or Android, the first (and easiest) step is to do a hard reset. This basically entails rebooting the phone’s software. A hard reset can be performed right on your phone, although the process differs depending on what type of device you own.

If you’re still staring at a blank screen, it’s possible that the cable connecting the logic board to the LCD screen has become disconnected. This can occur if you accidentally drop your phone a few times. In order to regain your screen’s functionality, the cable will need to be plugged back in.

If you want to repair a broken iPhone or Android this way, it’s best to seek help from a professional. While you may find DIY instructions online, you could risk causing irreparable damage to your device if you don’t know what you’re doing. So, if you suspect that your phone’s LCD cable is disconnected, search for a place in Las Vegas that fixes phones.

When your phone screen goes black randomly, it may be an indication that something is wrong with your operating system. In that case, a factory reset is often beneficial. During a factory reset, your device’s data and settings are completely wiped, returning the phone to its original state (i.e., the state it was in when you first purchased it).

Not sure how to do a factory reset on an iPhone or Android? The process is more involved than that of a hard reset but can still be done with moderate ease.

Keep in mind that this process takes longer than a simple hard reset – you may have to wait several minutes for your phone to restart. Once the process is complete, check to make sure the device has been restored to its factory settings. If you’re presented with the iOS Setup Assistant upon startup, you’ll know the reset was successful. From there, you can choose to restore your backed-up data.

Sometimes a power button can get stuck due to trapped gunk, debris, or sticky food. You can try to dislodge debris by pressing the button rapidly several times. In most cases, the most effective method for sticky buttons is applying a Q-tip with rubbing alcohol. Swab the area around the button to loosen up and extract dirt, dust, or whatever might be trapped in there. In some instances, you may have a broken button that will need to be repaired.

Your phone may not be charging properly if the charging port is blocked off due to grit or debris. Simply blowing on the port a few times can help. For a deeper clean, you can try gently scraping with a toothpick or using a cotton ball (or Q-tip) with rubbing alcohol. Some people recommend trying a low setting with a vacuum to extract dirt, but that can easily damage parts. Blowing out dirt with compressed air is a safer alternative.

Software issues with apps can sometimes cause a phone to act unpredictably. If you are noticing certain apps are crashing frequently, you should update them immediately. You should also consider deleting buggy apps for security and the health of your phone. If an app has crashed on your Android, you can force stop it through settings > apps & notifications -> see all apps -> force stop.

We’ll determine the root of the problem to get your phone up and running again as quickly as possible.

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.

However, sometimes the culprit could be an app or software glitch, hindering the functionality of key components like display assembly or motherboard. In that case, you can tackle the situation at home.

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:

In case you’re not sure about the process, it’s better to take help from a professional repair center. For Infinix, Itel, and TECNO users, Carlcare Service - being their official service center for these brands- is a recommended place to go.

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.

It won’t be aggregation if you call “Factory Reset” the mother of all solutions. It fixes most of the issues caused by an app or software glitch. The process actually brings your phone back to the factory setting by erasing all the apps and files you’ve downloaded post your phone purchase.

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.

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…

Using a multimeter, we can confirm that the strips are indeed set in series, so now we have to test each strip individually. Professionals use LED testers such as this one (about 40$ on amazon) but as I didn’t had one at the time, I decided to make one, McGyver style!
