My monitor is not turning on even though it is plugged in (external power supply)First, try another device in the same outlet to determine if the outlet is working properly.
Is everything firmly plugged in? It is easy for cables to become loose and not firmly connected, especially if you are using a mobile system. Please check to ensure everything is securely plugged in.
The LED light on the power supply should be GREEN. If the LED light is not on, then either the power supply is dead or there is no power being generated from the power source. Try another power source (outlet) and if this doesn’t work, there may be an issue with the power adapter.
Amber Light: The amber light indicates the monitor is receiving power but is not receiving the video signal being fed from the signal source (camera, computer, etc). This may also signify that the monitor is currently set to the wrong video input; you may need to press the “Auto/Switch” button to select the appropriate input (VGA, HDMI, etc).

My monitor screen is completely black, even though it is powered onIs everything firmly plugged in? A loss of video signal will cause the monitor to go black and then turn off entirely. It is easy for cables to become loose and not firmly connected, especially if you are using a mobile system. Please check to make sure everything is securely plugged in.
Your monitor possibly has TRU-Vu’s Dim-To-Black feature which allows you to control the screen’s brightness and contrast by pressing the arrow keys in the menu. The reason it has gone completely black could be because the dim-to-black was turned all the way down. Press the arrow up to the right to raise the brightness again. If this does nothing, try pressing the left arrow keys.
Why does my monitor keep entering sleep mode when I turn it on?The primary cause is usually that the monitor is not receiving a video signal from the signal source (camera, computer, etc). The monitor will automatically enter sleep mode if it cannot detect a video signal.
If the LED on the monitor is amber, this means the monitor is receiving power but not receiving a video signal from your source. Ensure the monitor is set to the correct input and try swapping out sources to determine if that is the root of the problem.
Why are there black bars and/or squeezing (banding) with my monitor?If there are black bars around your signal and/or a “squeezing” effect, this means that the aspect ratio of your monitor and the incoming video signal do not match.
Make sure the monitor’s picture size setting is set to the factory default, not zoom, fit or stretch. For optimal picture quality without distortion, black bars or squeezing, it is always best to match the aspect ratio of your video signal with the aspect ratio of the monitor.
How do I know if my monitor is really showing true 4K video?Make sure that that the signal you are sending is 4K resolution (3840x2160). You can test this by pressing the monitor’s Menu button. The monitor’s Menu screen will display the incoming video resolution and timing in the top-right corner of the screen.
My touch screen is not working.All touch panels must be connected to a computer via USB or RS232 cable. This allows the touch panel to communicate with the computer.
My touch screen is not registering correctlyAll non-HID compliant touch panels will need to be calibrated during the initial start-up and may need recalibrating at some other point in the future. This is accomplished via the touch panel software installed on your computer. For a detailed walk through, please contact us.
The buttons on my monitor are lockedKeylock is a safety feature offered by TRU-Vu to prevent unauthorized personnel from changing the desired monitor settings. We do not publish the lock codes for public knowledge; please contact us for the unlock codes.
The speakers are not very loud on my monitorTRU-Vu speakers are provided for signals and alerts; these are not intended for voice or music. If quality of sound is a major concern, we advise using external speakers.
My monitor is displaying a message saying “Sync Out of Range”If you are seeing this on your monitor, it means you are sending a video resolution to your monitor that is higher than your monitor’s native resolution.
Prepare the screen by turning it off and wait until it is cool to the touch. Cleaning warm or hot screens makes it more difficult to clean and can even damage the screen.
It is always recommended to spray the microfiber cloth first, then clean the screen with the moistened cloth. Do NOT spray the monitor screen directly.
For heavier duty cleaning, create a solution of 80% alcohol mixed with 20% water and use the damp, not wet, cloth to clean the screen and panel surface.
I need to clean my monitor screen (with protective glass)We highly recommend WHOOSH Screen Cleaner. It is 100% natural, non-toxic, and environmentally friendly. You can also use any standard glass cleaner.

If the model had attached with the power supply (AC-adapter), make sure the power supply has connected to the screen. Please check if the light of power supply is ON. If the light is NOT ON, change another power supply to test.
Are there any regional differences inpower specifications thatASUS LCD monitor supported (for example: If monitor was bought in Taiwan, can it be used in China or other countries?)
ASUS LCD monitor can support power specification: AC 100-240V. As long as within this voltage range, the display can work properly. However, please be noted that if you bought a monitor from another region, the power cord is not necessarily compatible to power outlet. Customer should replace the appropriate power cord or plug adapter in order to ensure normal power supply of the display.
A factory reset does not erase the monitor’s language setting. After you perform a factory reset, you will need to re-enter your custom settings, such as contrast, brightness and image ratio.
You need to open the OSD (On Screen Display) Menu by using the buttons located on the bottom right corner of the display. You need to press the Menu button, then go to the Management section and initiate the factory defaults/reset option.
Reset your computer when all other options failOn the sign-in screen, press and hold the shift key, click the power icon , select Restart, and continue pressing the shift key until the Choose an option screen displays.
To view the settings menu, press the joystick button at the bottom of the monitor and then enter the Settings. When you enter the menu, instructions on how to use the button will appear in the bottom right corner of the screen.
Make sure the computer is turned on. If using multiple displays (such as a laptop screen), make sure the computer has multiple displays enabled. Make sure the cables are securely connected, both on the monitor and on the PC. Try a different cable.
In short, yes, a factory reset will usually remove viruses … but (there’s always a ‘but’ isn’t there?) not always. Due to the wide variety and ever evolving nature of computer viruses, it’s impossible to say for sure that a factory reset will be the answer to curing your device from a malware infection.
This function allows you to lock the current control settings, so that these settings are not inadvertently changed. To lock the OSD settings, press and hold the MENU buttonfor several seconds. The message “OSD LOCKED” appears. You can unlock the OSD settings at any time by pushing the MENU button for several seconds.
In particular, ensure your monitor is plugged into the wall and receiving power, and double-check that the cable going to your PC is firmly plugged in at both ends. If you have a graphics card, your monitor should be plugged into that, not the HDMI port on your motherboard.
If the new monitor works, the original monitor or its cables are faulty. Try connecting the monitor with a different video cable. If the monitor still does not work, replace the monitor power cable. Replace or service the monitor if it still does not turn on.
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.
If the issue persists on the other monitor it may be due to the video card (GPU) or video settings and not the monitor, go to the step Verify display or video issue in Windows Safe Mode. Else go to the next step.
Performance issues may occur if there is any type of damage that is caused to the display cables or the LCD screen. LCD screen may show that symptoms like LCD screen stops working, work intermittently, color mismatch, flickering, display horizontal or vertical lines if there is damage to the display cables or the LCD screen.
If you do 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 monitors provide a self-test feature check (SFTC) and an integrated self-test (BIST) or integrated diagnostic (BID) tool that helps determine if the screen abnormality you are experiencing is an inherent problem with the Dell monitor or with the video card (GPU) and computer settings.
When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines, color fade, it is a good practice to isolate the monitor by running a diagnostic test on the Dell monitor.
NOTE: Self-test feature check (SFTC) helps check if the Dell monitor is working normally as a stand-alone device. To check for screen abnormalities such as flickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines, color fade, and so on, run the integrated self-test (BIST) or integrated diagnostic (BID) test.
NOTE: In certain Dell monitors, the integrated self-test (BIST) or integrated diagnostics (BID) can be run only when one or more video cables are unplugged and the Dell monitor is in self-test mode.
Dell monitors can be reset to factory default settings using the on-screen display (OSD) menu. This can be accessed using the buttons or joystick that is available on the Dell monitor. For step-by-step instructions to reset a Dell monitor to factory default settings, see the User Guide of your Dell monitor at the Dell Manuals website.
NOTE: Connect the USB upstream cable from your Dell touch-capable monitor to a working USB port on the computer. This is essential for the touch feature to work.
If the diagnostic tests on the Dell monitor and video card (GPU) passed, it is most definitely an issue that is related to software that is installed on your computer. If the above troubleshooting steps did not resolve the issue, to restore your computer to factory defaults as a last resort.
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.
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:
Display settings like brightness, refresh rate, resolution, and power management may affect the performance of the LCD screen on your Dell laptop. Changing or adjusting the display settings can help resolve several types of video issues.
NOTE: Depending on the model of the Dell laptop, the shortcut keys to adjust or change the brightness may differ. See the User Guide or User Manual of your Dell laptop for model-specific information.
If 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.
Just like televisions, laptop displays start to flicker too after a few years. You may sometimes also notice the display turning blank even when the laptop is on. Alternatively, you might find some white lines running down the display.
If the DC jack has broken, you can try adjusting the plug’s angle in its jack. If you see some lights turning on but the device is still not booting, it’s time to replace the DC jack. If that doesn’t help, it’s a clear indication of a motherboard-related issue. You can either get the motherboard repaired or replaced by the brand service center. Getting the motherboard repaired could cost you anywhere up to Rs 10,000, whereas the cost of replacing the motherboard can go anywhere up to Rs 25,000.
If you ever notice multi-coloured or single-coloured vertical lines on your laptop screen, it may be a result of a hardware failure or due to damage to the screen. To try fixing it yourself, first unplug your laptop, hold the power button for 30 seconds and restart the laptop. If you continue to see coloured lines, the issue is probably with the LCD screen, which will need to be replaced from the brand’s service center. To be sure about the LCD screen problem, try connecting your laptop to another monitor and see if the issue persists. If it does, the issue is certainly in the LCD panel.
On turning on the laptop when you see the lights blinking and hear the fan working but if the laptop screen is blank and doesn’t display anything, this is again an indication of a faulty motherboard. The first thing to do is to transfer all the data to another drive to make sure your data is safe. Before going ahead and getting the motherboard repaired or replaced, you could try performing a hard reset (also known as a factory reset), which can mostly help in resolving the blank display issue.
Firstly, check if your laptop’s brightness level is set to maximum. If the display is still dim, try restarting the device. This could just be a system error that can be resolved by restarting the device. Also, check if the AC adapter cord is loose and firmly connect it to the outlet and laptop. If the issue still persists, it is mostly due to a failure of the LCD. Behind the LCD, there is an inverter board and backlight bulb which control the picture.
The inverter board converts the low voltage your laptop uses, into higher voltage required by the long bulb that lights up the LCD screen. If the inverter board or bulb fail, you will experience the problem of a dimmed display. Even if one of these two components fail, the screen will need to be replaced, unless the service center can help by just replacing the bulb. We wouldn’t recommend you try resolving it yourself, as this is more complex and you could end up damaging the circuit board and the backlight lamp. So, it’s best to leave this job to an expert.
Laptops are fragile and can easily break, especially with more and more thinner and lighter models being launched now. Some of the most common ways how a laptop is damaged include: when it accidentally falls and the screen cracks, when it’s held at an awkward angle or if you unknowingly placed something heavy on the laptop. Remember, a cracked laptop screen can affect the overall functioning of the device in some cases.
Since brands do not cover the laptop screen, it’s best to get your device covered with a protection plan in advance. Screen replacements are expensive and can cost you anywhere up to Rs. 15,000 but if you have the
Slowly drag your finger to the bottom right corner without lifting. Try to move your finger slowly enough that you can count to 10 before reaching the opposite corner of the screen.
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.
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 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.
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.
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.
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.
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.
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.
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.
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.
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).
The LCD screen is vital for operating the printer. Should you encounter any kind of trouble, such as a dead screen, corrupted text, or other issues, please refer to the guide below.
First of all, unscrew the LCD screen from the printer frame, remove both M3x10 screw holding it the LCD board in the plastic casing, and remove it from the casing. See if the problem still appears when the LCD is not pressed by the casing.
Firmware updates are necessary to keep your printer up to date. However, the installation of incorrect firmware can lead to letter corruption on the LCD screen. There"s an easy fix, though:
There is a small chance the printer"s LCD screen can glitch out by electrostatic discharge when inserting the SD card. Try to turn the printer off and on again.
This problem usually appears only on user-assembled printers. If your printer"s LCD screen remains blank or displays corrupted symbols after you turn on the printer, there is a chance it is caused by incorrect wiring. Follow these steps to fix the issue.
Double-check that all cables are properly seated and they are not visibly damaged. Depending on the model of your printer, please refer to the following guides for information on how to make sure the cables are properly connected: Einsy RAMBo electronics wiring (MK3/MK3S/MK3S+) and Mini RAMBo electronics wiring (MK2S, MK2.5, MK2.5S).
If you suspect that the LCD ribbon cables connectors are not firmly seated in the slots, disconnect the LCD ribbon cables and check the slots for any bent pins. If there are bent pins, you can use tweezers to fix them. However, be very careful not to break the pin(s) completely.
