what causes lcd screen to go black factory

After a long, hard day, you finally sit down to catch up on your favorite show. But when you hit the power button on your remote control, your TV screen stays black! You try pressing the remote’s power button again and again from every angle, but still, your TV has no picture. If this sounds familiar, you’ve likely fallen victim to one or more TV screen issues.

What causes a TV screen to go black? Software issues, loose connections, or backlight problems are usually behind black TV screens. Learn about each of these causes and get tips for troubleshooting them so you can get back to relaxing with your favorite TV shows, movies, and video games.

If your TV screen is black and there’s no sound, you’ll want to check for an LED light or a small indicator light that tells you the TV has power. If there is no power to the TV while it is plugged in, there may be an issue with the outlet or fuse box in your home. However, if the TV is on but the screen is black, the problem could lie with your TV’s software.

Unplug the TV from the wall, and, if possible, remove the power cord from the back of the TV to perform a soft reset. Wait 30 seconds, and plug the TV back into a working outlet to test it again. If you’re still having screen issues, you might want to bring in an expert — they’ll know how to fix your TV’s black screen.

If your TV screen goes black but the sound still works, the first thing to check is the input source to ensure it is turned on and operating correctly. This includes external devices like cable boxes, video game consoles, laptops, and streaming devices. Once you’re sure the input source is working properly and you have the right input settings, check the cable connections. In many instances where the TV screen is black but the audio works, poor cable connections could be the issue.

Whether you’re working with an HDMI cable, RCA (usually yellow, white, and red cables) set up, or another type of connection, you need to ensure the cables are seated properly and firmly into their connection ports. With a good connection, the cable shouldn’t feel loose or easily disconnect when pulled on or moved around. If all your cables have a snug fit but the problem persists, try connecting the device to another TV. If your TV screen is still blacked out, you may need new cables.

Some TV displays, such as LCD screens, use a backlight to illuminate the picture. If the backlight burns out or stops working, it will result in a blank TV screen.

To check your TV’s backlight, make sure your TV is on. Then, turn off the lights in the room and shine a flashlight on the screen. If you can see a picture with the flashlight, then your TV’s backlight is likely burnt out.

While you might be eager to learn how to fix a black-screen TV, a broken backlight does not come with an easy solution. The backlight will need to be replaced, and it’s best to get help from a professional with this task.

Sometimes it turns out that on pressing the power button on your TV you"re not getting a picture and a sound. The first thing you are to determine whether it is a TV issue or a power issue. To check if power is supplied to the TV unplug the power cord from the back of the TV or the wall outlet. While it is unplugged, disconnect all external devices from the TV.

Hold pressed a power button on the TV for several seconds. Reconnect the power cord. Then, as you press the power button, look at the LED power indicator light. If it is not lighting up at all unplug the power cord from the TV and from the wall outlet and securely and tightly plug it back in.

Verify if the surge protector or an extension is turned on in case a power cord is connected to these devices. If a TV screen appears black, plug another device into the socket to check whether this device is getting power from the outlet. If power is supplied to the outlet it means that your TV is powering on and a picture issue should be revised. You need to make a call to the TUSA Service Center and our technician will soon revive your TV.

There are many possible problems in case your TV is powered but a TV screen goes black and there is no sound. All you can do in this case at home is to reset your TV to the factory defaults. This procedure is described in the User Manual of your TV.

If the result is negative, you can trigger the MENU to reset your TV to the factory defaults.

Highlight YES and press “ENTER”. The TV will turn off automatically after a few seconds. After the TV turns off, unplug the TV power cord and then plug it in again to complete the reset process.

In case neither of the above steps resolved the problem of the TV, you are welcome to get urgent assistance with this problem by contacting the TUSA Service Center.

Sometimes when watching TV, annoying situations arise when a TV screen fades off to black. That is to say, the TV screen goes black at random times and appears to be off but the sound is available and the power light is still illuminating. A troubleshooting procedure may differ for a variety of TV brands but generally will work the same to fix the problem and is as the following:

Use a different HDMI port for the device you are using. Unplug the HDMI from one input and plug it to a different input to test if a port is bad. Checking and reconnecting HDMI cable on the back of your TV along with switching the inputs to BLU-RAY and CABLE may lead to the expected positive result.

Connect a different device to the TV or the same device to another TV. The device being used (Ex. Blu-Ray/CABLE BOX) may cause the black screen issue.

Turn the device (Ex. Blu-Ray/CABLE BOX) you are using OFF and then back ON. The device you are using may have a temporary fault and needs to be reset.

A hidden fault within HDMI cable – Replace with new High-Speed HDMI 2.0 cable. Replace the HDMI cable as it may have a short or another defect which causes the black screen issue.

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.

Make sure the buttons on your device are not jammed. First, inspect the buttons to be sure they"re not caked with dirt, lotion, lint, or other debris. Then try freeing the buttons by pressing the button several times in quick successions. The button should free depress and release with each press.

Inspect and clean the charging port. Dust and debris could keep your phone from charging properly. Inspect and clean the charging port. If necessary you can gently blow into the charging port, or use a wooden toothpick to try to remove anything that"s stuck in the port. Once it"s clean, plug your phone in and let it charge for about 10 minutes. After it"s charged for a short while, try restarting the phone.

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.

Force restart the phone. Many critical system errors can be cleared up with a force restart. Depending on the model Android phone you have you may need to use some combination of buttons to force restart the phone, including:

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 possible, remove the battery, wait 30 seconds or more, and then reinstall the battery and start your phone. If cannot remove the battery from your phone, you"ll need to allow your phone to discharge completely. Then recharge it and try to restart the phone again.

Use caution when taking your phone apart to remove the battery. If you have a newer phone that"s hard to open with the appropriate tools, take the device to a professional who can help. Otherwise, you run the risk of doing further damage to your phone.

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.

Choosing Factory data reset will delete all the data, including pictures, music, etc., from your phone, so if possible, back up your Android phone so you can restore your data once the phone is working properly.

If you have a Samsung phone, use the Samsung Smart Switch to connect your phone to your computer, and then try to access it, reboot it, or back it up from there.

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.

When changing up which buttons you"re holding, you may have to try a few times to get the timing exactly right. It should be about 10 seconds before you switch to the new buttons (but keep the power button depressed all the time), but switching too soon or too late will cause the phone not to boot into Recovery Mode.

Clear the cache on your Android phone. This deletes temporary files and frees resources, which could resolve whatever issue is preventing the display from turning on.

Try a factory data reset. This will restore the phone to factory settings, which deletes all your data, so be sure you have a backup of anything you don"t want to lose before you start this process, if possible.

To restart your Android device, hold down the power button for several seconds and select Restart from the menu that appears. If that doesn’t work, do a hard restart by holding down both the power and volume up buttons for up to 20 seconds.

Android is known for its vast array of brands and models, spanning all budgets. Our favorites are the Samsung Galaxy Note20 Ultra and Google Pixel 4a 5G.

Overall, iPhones are of better quality than Android phones. A premium-priced Android phone is about as good as the iPhone, but cheaper Androids are prone to issues. Android phones surpass the iPhone in several categories, like battery life and voice assistant—it’s all about the features that are most important to you.

If you want to repair this problem you’ll have to change your TV’s backlight. But unfortunately, not all people are familiar with this concern. Thus seeking help from a professional is highly recommended. However, if you have just purchased your TV recently, you might be able to have it changed under the manufacturer’s warranty.

In the actual fact, according to CNET, one of the most common issues with TVs most especially Samsung TVs involves the capacitor found inside the television. A television set that has his particular problem will not power up or display a picture.

If you are attempting to check the picture from a cable box or other devices, swap it for another device. However, if it doesn’t work, consider accessing the setting menu on your TV.

Doing this job is pretty complicated. As a matter of fact, the board’s model number and the methods that you are going to use will greatly differ from TV to TV. But one thing is for sure, it is a fix that everybody can perform at home with an insignificant experience.

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.

This diagnostic solution page should help you identify the cause of your broken smartphone screen and find a suitable solution to get your phone back up and running. If you’re having trouble with a black or blank screen on your Galaxy S20, S20 Plus, or S20 Ultra, this is the page for you.

If your screen is displaying images, but is having problems with touch input, try our Samsung Galaxy S20 Touchscreen Unresponsive solution page instead!

It’s possible that your phone screen isn’t displaying any images because the phone is off and the battery is dead. Normally, trying to turn on the phone with a low battery will prompt a display on the screen telling you to charge the phone, but if the battery is sufficiently discharged, the screen may not have enough power to display the prompt.

Try connecting your phone to a charging setup you know is functional for at least 20 minutes.You can test your setup with another USB-C device to ensure it’s providing power.

It’s also possible that your battery can’t charge because your USB-C port isn’t able to transmit power to the battery. If you have a wireless charging setup, you can try charging your phone wirelessly to circumvent the bunk USB-C port, or try gently cleaning out the USB-C port with a toothpick, isopropyl alcohol, and/or compressed air. (Pro Tip: use a dust blower to avoid the harmful environmental impact of spray can dusters.) Once you’ve connected your phone to a power source you know is working, try turning on the phone again.

If your phone still didn’t turn on, there may be a software issue preventing your phone from booting up. Just in case your phone is afflicted, you should perform a force restart while your phone is still connected to the charger:

Temporary files, background processes, and system glitches can cause your Samsung Galaxy S20"s screen to go black and prevent an image from showing. To reset any firmware blips, you can perform a force restart on your phone. To force restart the Galaxy S20:

If the screen is still acting faulty, then you may try backing up your personal data (videos, photos, music files, etc.) and performing a factory reset on your phone. This option will delete all of the files and applications from your phone, starting it back up as if it was new. While this may remedy your problem in a less invasive way than some other options, you should only do so if you are fairly confident that the issue is a software problem. To perform a factory reset on your Galaxy S20:

Lithium Ion batteries like the one found in your Galaxy S20 are only rated for around 400-500 charge cycles before the battery capacity degrades to 80%. For most regular users, this will happen at the 1-1.5 year mark, at which the user will notice that their battery holds less charge and takes longer to reach a full charge. However, at around 50-60% capacity, the battery will start to fail to hold a useful charge and may even struggle with providing adequate power to handle the performance of the phone. If you’ve been using your phone for 2-3+ years and have amassed a thousand or more charge cycles, your phone may have trouble starting the hardware up, even when fully charged.

Additionally, lithium-ion batteries like the one in your Galaxy S20 don’t like to be kept at the extreme ends of their charge range (fully-charged or fully-discharged) for long periods of time. If you’ve kept your phone’s battery at one of these extremes (especially fully discharged) for multiple weeks or months, this may have degraded the battery life significantly, even if your charge cycle count is relatively low.

It’s possible that the screen won’t turn on because of a faulty battery. Although the phone should be able to power on without the battery while connected to a power source, some cases may prevent this from happening.

Case 1: If your battery and USB-C port are both malfunctioning, you won’t be able to turn on the phone because no power is getting to it. You may be able to provide power to the phone wirelessly, but because the battery is incapable of holding a charge, the phone loses power once the phone is lifted up to try to turn it on. To attempt to test this, you can try turning on the phone while it is resting on the wireless charging pad, being careful not to disturb or interrupt the wireless power. However, wireless charging outputs much less power than cable charging, so this may not be enough to power your phone. If your phone does turn on using this method, you’ll want to replace the daughterboard containing the USB-C port, as this will allow you to charge your phone moving forward. You’ll probably want to replace the battery too while you’re at it—Galaxy phones are notoriously glued down, so it’s best not to have to open them twice.

Case 2: If your battery is swelling, the change in volume might dislodge some important componentry within your phone, such as unplugging the display cable. In order to move around components, the battery will likely need to have swollen somewhat significantly, so you can check your phone’s physical appearance for bulging. Be sure to take off any cases before you check, as even the slightest bulge can indicate serious problems with your battery. If your phone is bulging, you should replace your battery immediately. You can use this Samsung Galaxy S20 Battery Replacement guide to do so, but if you haven’t taken apart a phone before, this may be a case to enlist an experienced repair technician. Swollen batteries can present several dangers, such as chemical leakage or combustion, so it’s important to use extreme caution while handling one. Be sure to dispose of your swollen battery properly as well—you can’t throw them in the trash!

If you’ve eliminated discharged/faulty batteries and software issues as a cause for your faulty screen, the most likely culprit is a broken display. The OLED display on the Samsung Galaxy S20 is responsible for generating the images and colors on the screen. It consists of a film of organic compound which generates light when an electric current is passed through it. Unfortunately, this film is subject to damage when it experiences ingress from oxygen or water, so cracks on the screen can potentially cause damage to the display, causing black spots or distortion. If your screen has significant visible damage such as large cracks, or if your phone has been submerged for a substantial amount of time or at great depths, this may be the cause of your display degradation. In any case, you will likely want to replace the display assembly of your Galaxy S20 device. You can do so using one of our screen replacement guides:

Although a rarer case than a broken screen, it’s possible that a faulty motherboard is preventing the entire phone from functioning. Since the motherboard controls all of the processes of the phone, its malfunction would prevent the screen from displaying images or accepting touch input. The most common ways to damage a motherboard (assuming the phone isn’t open) are by allowing water to penetrate the case or by unsuccessfully changing the BIOS settings (usually when attempting to “root” the phone).

Water damage will cause short circuits and corrosion on the motherboard, so if you do open the phone to start replacing components, you can take a look for any spots that look corroded as evidence. If you do see corrosion that looks localized, you might be able to clean it off with some 99% isopropyl alcohol to regain functionality of the phone.

Changes to the BIOS settings can also brick the motherboard, rendering it useless, but will only happen when trying to mess with the underlying operating software—so it’ll be fairly obvious this is the case if you were trying to root when it happened. Unfortunately, bricking the motherboard is oftentimes an irreversible process, so while you might be able to recover it with the help of an expert (why didn’t you have them root your phone in the first place?) it oftentimes means you’ll have to opt for a motherboard replacement.

If you need to reset your Sharp TV and reset because of a black screen with no picture, turn off your TV using the Power button on the TV Remote. Then, wait for one half minute to one minute and turn the TV on again and check to see if any picture is appearing.

Replace the HDMI cable as it may have a short or another defect which causes the black screen issue. Unplug the TV for 5 minutes to attempt a reset. Unplugging the TV will reset the television and clear any temporary issues. Factory reset of the TV to resolve the issue.

If Picture mode is set to Cinema or Custom, the screen may become dark. If the screen is still dark after the picture quality mode is changed, change the setting Backlight, Picture, Brightness and adjust the brightness to your taste. 2. If Power Saving is set to Low or High, the screen becomes dark.

If your TV is getting its signal from an external source. i.e. a cable box or a DVD player, then the possible reason why it is not displaying a picture is that the cable connecting the TV to the cable box or DVD player is loose or damaged. The cable that is responsible for displaying a picture is the yellow cable.

In “Setting mode (administrator)”, select [Energy Save] → [Power Management Setting] → [Auto Power Shut-Off]. A message appears 15 seconds before Auto Power Shut-Off Mode is entered. To close the message and continue normal operation, tap the [Continue] button.

A Sharp TV would typically last for five to seven years. However, its lifespan could increase to ten years depending on the frequency of use and how well-kept it is.

Simultaneously, press and hold down the Power and Volume Down (-) buttons on the TV (not on the remote), and while holding the buttons, plug the power cord back in.

Press the ACTION MENU or (Quick Settings) button. The next steps will vary depending on your TV menu options: Select System → About → Reset → Factory data reset → Erase everything → Yes. Select Device Preferences → Reset → Factory data reset → Erase everything → Yes.

Calibrate the Backlight, Contrast, Brightness, Color, Tint and Sharpness options by highlighting the option with the remote’s up and down arrow keys, and then pressing the left or right arrow keys to make adjustments.

A loose connection can cause your TV to turn off unexpectedly, and so can an aging power supply cord. If you notice frayed wires or damage to your TV’s power cord, it’s time to shop for a new TV to prevent further issues and potential electrical hazards.

Depending on the make and model of your TV, use a screwdriver to unscrew the TV fuse cap holder. Then, carefully check the fuse wire. If you can see a visible gap between the wires or a visible metallic or dark smear inside the glass, you have a blown TV fuse.

Try unplugging the TV from the electrical outlet. While its unplugged, hold down the power button on the TV itself for about 30 seconds. Once that time is up, release the button and plug it back into power. Power the unit back up and see if you can see any imagery.

Check your TV settings to see if it is on power saver mode. If it is on a power saver, your screen will automatically power off while the sound is still active. Hence, if your TV has this feature, we recommend that you disable the power saver mode or Energy save mode to ensure no interruptions while viewing.

1 – Unplug TV overnight. Plug back in and SOMETIMES it may work and fix your issue. 2 – Unplugging the TV and everything hooked to it, then plugging it back in may clear the problem. 3 – Be sure the TV is set to the correct input.

If your Sharp TV won’t turn on, you need to reset it. Unplug your TV and wait a full 60 seconds. While the TV is unplugged, press and hold the power button for 30 seconds. After the 60 seconds are up, plug your Sharp TV back in and it should work.

The blinking of either the power light or the OPC (Optical Picture Control) light is an error message or fault code. It is not easy to tell what is causing the error. It may be a setting on the television, it might be a problem with the firmware or a mechanical issue that requires service.

By and large, the current crop of Sharp TVs appear decent value if you pick the right one. The Roku TV access is a welcome feature and you get a lot of screen estate for your money. There are caveats, however. We’d check the TV’s price tag against the price of a similar sized Samsung or LG.
