Suggested April 2024 Computer Turns On But The Screen Is Black
When your computer displays a black screen, it means that the data it is trying to display is not being received. To fix your displays, you must first identify the source of the problem.Computer Displaying Black Screen
Once you’ve ruled out a broken monitor or faulty cable, you’ll have to look deeper into the computer to figure out what’s preventing it from working.
Here are a few common causes of a screen staying black even when the computer is on.
BIOS settingsHow to Fix a Computer that Turns On But the Screen is Black
The best way to troubleshoot a computer is to start with easy fixes that only take a few moments. If these fixes don’t help restore the picture to your display, you might have to test some of your computer’s components.Restart the Computer
One of the first things you should do is make sure your computer is completely restarted. Sometimes when you think your computer is off, it is actually still on in a low-power state to speed up startups. Powering the computer down all the way ensures that when you restart it, it’s a truly fresh start.
To restart your computer completely, press down on the computer’s power button. Hold it down for five seconds before releasing it. Let the computer fully startup before you continue troubleshooting.Check the Connections
Make sure your monitor is plugged into your video output device. Some motherboards have onboard graphics and can work without a GPU. Others don’t have graphics built into them and require a GPU to display anything.
If you have a GPU, make sure the monitor is plugged directly into it. If you don’t, make sure it’s plugged into the motherboard.
You should also ensure that all power cables required by the computer are plugged in. If your GPU needs a supplemental connection, it might prevent the computer from sending video to your display.Check for Brightness
Sometimes the brightness on your system is so low that you think nothing is displayed on the screen because it’s not visible.
Look at your keyboard for a brightness hotkey you might have adjusted without meaning to. Press the keys to turn up the brightness while the computer is connected to a display you think is working.Reset your Monitor
Resetting the monitor will ensure that you don’t have strange settings incompatible with the computer selected. The method will vary depending on what monitor you have.
Make sure the input is selected for the computer. If you’ve changed what wires you’re using to connect the monitor to the computer, you might also need to change the input settings.
When the monitor is set to default, restart your computer and see whether it grabs a connection.Check your Peripheral Devices
Unplug anything unnecessary from the computer, like extra monitors, external drives, or USB hubs.
Restart the computer with a single monitor plugged in. If the screen is still black, try switching the cable that connects the monitor to another one. Try plugging it in with a different cable type or to a different port in your computer.
Once you know the monitor is working, the cable is suitable, and your computer doesn’t have one flawed connector, it’s time to start thinking about what else might have failed for the monitor to display a black screen.Change the RAM
Try removing all the RAM from your computer, inserting one stick into a slot, and booting with that single stick inserted. If that doesn’t work, try another stick in the same slot.
Try one stick in a different slot if it still doesn’t work. With this method, you’re trying to find damaged slots or damaged RAM sticks. If it starts and works with a single RAM stick in a specific place, you might have damaged RAM, or your slots are damaged.Test Your Power Supply
Even when the power supply appears to be working, it can fall victim to errors that prevent all computer parts from receiving sufficient power.
Consider getting a power supply tester if you frequently work with computers. It’s a safer and easier way to test a PSU than using a multimeter.
Unplug and open your computer.
Remove any power cables going from the PSU into other components. It shouldn’t be connected to anything when you’re done.
Check the voltage switch on the PSU to make sure it’s correct. The setting for US computers is 110V/115V.
Plugin the larger power connector and one of the smaller ones, depending on the model you’re using.
Plug your PSU into a wall outlet. Turn the power on if it’s a model with a switch.
Turn the power supply tester on and refer to the screen on the device. If the screen isn’t turning on, the power supply is bad.
Check to make sure none of the numbers say LL or HH. That means the power supply is bad and needs to be replaced.
Check your power supply tester manual against the voltages reported on the screen. Make sure they’re within the correct limits for your PSU. If the numbers are out of the acceptable range or the delay value is not 100-500ms, you should replace the power supply.
Check the other cables, if necessary. It depends on what model PSU you’re using and what power cables extend from it.Listen for Beep Codes
Some computers make sounds when something is wrong with the system. These beep codes help you troubleshoot and fix any problems preventing it from working correctly.
Power on the computer.
Listen for the beep codes.
Write down how many beeps there were, whether they were fast or slow and whether the code repeated. It’s okay if you have to turn on the computer a few times to catch the code perfectly.
Refer to a manual or reference for your BIOS model to determine what is causing the beep code.
Recognizing the cause of a beep code isn’t the end of the problem because you still have to fix whatever caused it. However, it’s a great starting point for finding the source of the problem.Clear your CMOS
Clearing your CMOS battery on your motherboard will reset BIOS to default. If a problem with your BIOS settings prevents your computer from displaying an image on your monitor, clearing the CMOS should fix it.
Shut down the computer and disconnect the power.
Press the power button on the computer three times.
Locate the CMOS battery on the motherboard.
Remove it from the socket.
Wait five minutes.
Place it back into the socket and restart your computer.
Your BIOS will be back to the way it was when your first turned on your computer. If you ever flashed the BIOS to upgrade it, you may need to repeat the process.Test your GPU
Your GPU could experience a problem that prevents it from displaying on the screen. However, it’s not as easy to test as some other parts.
The standard way to test a GPU is to run a series of benchmark programs to see what it can handle. That’s not possible when you can’t see your screen.
The best way to check your GPU is to hook it into another computer to which you have access. See whether that computer boots. If it does, run a stress test on the GPU.
Download a program like 3dMark, Unigine Heaven, or FurMark and use it to make sure your GPU is working as intended.
If the GPU isn’t working right, you can try disassembling it, cleaning it, putting on a new thermal paste, and then reassembling it. Sometimes that can help manage the temperatures and keep the GPU more stable.Reseat Your Cpu and Reapply Thermal Paste
If your CPU isn’t seated perfectly or isn’t as cool as it should be, it might cause errors that prevent your computer from displaying an image.
You should also take a closer look at your CPU cooler. If that isn’t functioning correctly, it can cause your CPU to overheat and prevent your computer from working.Clean and Reseat Your Components
It’s surprising how often a thorough cleaning and reseating of all your components can fix errors for a computer. Take your time and be gentle as you work through each part.
Turn off the computer, unplug it from its power source, and press the power button a few times once the power is off.
Remove the motherboard, GPU, and drives. Disconnect everything.
Pull the RAM from its slots.
Use compressed air to blow dust from the inside of the case.
Clean any removable filters and the blades on your fans.
Use compressed air again to remove any dust that has fallen during the rest of the cleaning.
Reseat the ram into its slots.
Replace the fans and coolers.
Replace the PSU, GPU, and any AIO coolers for the GPU.
Plug everything back in properly.
Reconnect the power.
Restart the computer.
If the computer starts normally, it may be that something simply needs to be adjusted a bit.Look for Damage on the Computer Hardware
Look for things like blown capacitors and electrical shorts on your motherboard. You might notice burned areas, bulging pieces, or exposed wiring.
If something is damaged on your motherboard, you might have to replace it entirely to make your computer work again. Unfortunately, replacing aspects of your motherboard is pretty complicated, and most of the time, it makes more sense to get a new one.Frequently Asked Questions Why Does My Computer Screen Go Black Randomly?
It’s possible that your display is not working. However, if your screen is going black randomly at different times, one of your computer components might also fail. Stress-test your components to see whether the CPU or GPU are close to dying, experiencing high heat, or having other problems.Why Is My Computer Screen Black With a Cursor?
This can be caused by many different issues, including outdated drivers or BIOS issues. Try restarting your computer, using Windows key + R to access Device Manager to update your drivers, and booting the computer into safe mode to run System File Checker.How to Stop a Computer Screen From Going Black?
Check your settings to see whether you’re on a power plan that turns off the display. When the computer doesn’t sense movement or use for a while, it will shut down the displays even if it leaves the hard drives on. You can adjust your power plan’s settings not to turn off the display or select another power plan without that feature.

If you encounter the Black screen of death on your Windows, it’s due to a number of reasons including – Overheating, update issues, a power supply issue and software or driver errors. This issue can be easily fixed in most cases, but if you encounter this issue on the regular, it’s most likely you have a hardware issue – and you may require the services of a PC hardware technician to diagnose your device.How do I fix a Black screen on startup Windows 10? Is it safe to turn off your computer by pressing the Power button?
Except in cases of system freeze, do not make the practice of turning off your computer with the physical power button, as the button is designed only as a power-on button. It is very important that you shut down your system properly because simply turning the system off using the power button can potentially cause serious system file corruption.

It can be a serious issue when your Samsung TV abruptly enters a black screen of death. You can either experience a completely dead TV or a black screen with background sound.
Although there are many reasons behind the black screen problem, it is reported to arise mostly due to a glitch in the power circuitry of the TV or weak input signals. Nonetheless, poor cable connections, overheating, outdated firmware, or damage to display components are also possible reasons behind the issue.
Whatever the causes are, this article will guide you through different troubleshooting methods to help solve the black screen problem.
As we already mentioned, the black screen problem is primarily due to power glitches. You can solve this glitch by simply draining the residual power from the TV capacitors. For this, turn off the TV and keep pressing the power button for a few seconds, then turn your TV back on. We also suggest using a voltage regulator like a stabilizer or UPS to maintain constant voltage flow.
However, if that does not work, we have compiled a list of 10 fixes you can apply to solve the problem. Let’s dive straight into them.
The first thing you need to do is to change the input mode on the TV. If the signal of the currently selected input mode degrades or goes off while watching TV, it will end up with a black screen. So, you should try switching to another available input mode.
For instance, if your TV is connected to the set-top box via HDMI mode, try changing your source to USB mode. Take a USB drive with some videos and play them on your TV. If you don’t encounter the black screen problem while streaming from USB mode, there is probably an issue with either the HDMI cable or set-top box. This way, you can know if only a particular source is faulty or if your TV is itself a problem.
You may be using either a cable box, satellite dish, or some other form as an input source of the TV. The wire connections can sometimes get loose, and your TV may show a black screen. So, inspect every connection cable and tighten them if they are loose. You can also unplug and re-plug them.
If you are a satellite dish user, climatic conditions can affect signal quality. It can not only distort the TV signal but also wholly turn the TV screen black. It will help if you wait till the climate gets back to normal. You can also check the quality of the signal you receive on your TV.
Next, you can remove any devices connected to your TV. Sometimes a problematic device connected to your TV can lead to black screen problems. Remove devices like USB, DVD players, and gaming consoles and isolate the TV to cast from the cable box only.
This is the most common mistake people out there make. If you have a power saving or sleep mode enabled on your TV, the display goes off after a specified time, and a black screen is shown by default. It is simply a feature of power saver mode, and you don’t need to worry. If you think you have enabled the feature accidentally, you can disable it easily.
Samsung TVs have the option to run a self-diagnosis test that includes video testing, picture testing, HDMI testing, and much more. With this test, the TV will diagnose if there is any issue that may possibly be causing the black screen of death. Simply run the test and follow the on-screen instructions to solve the problem.
Sometimes, an application running on your TV might also be a culprit behind the black screen of death. While using some applications, you might have noticed a black screen on your mobile phone. The case is the same with the TV as well.
If the application is not supported by your TV’s operating system or specifications, it will throw a black screen error as soon as you launch the app or in between the application session.
This issue is solely caused due to problems in that specific app. If you are facing a similar kind of error, you can at any time update the application. If updating does not solve the problem, you can completely uninstall it to get rid of the problem.
Picture settings on the TV should be set such that it is suitable for what you are viewing on the screen. If the images or videos you are watching and the picture settings do not match, it can throw a black screen of death. Therefore, depending upon the resolution of the content to watch, you need to change the picture size on your Samsung TV.
Another reason for the black screen on your Samsung TV is the outdated firmware. With outdated firmware, the applications and devices connected to the TV can not coordinate properly with the hardware resulting in a black screen. So, always make sure your TV has up-to-date firmware.
Resetting the TV can come in handy if the firmware update process has been interrupted and you start facing the black screen of death. Power interruption during the update process will cause the TV to brick, eventually throwing a black screen error.
Resetting will help revert everything to factory defaults. You may also perform a reset as a last resort to solve the black screen problem.
In the worst case, the display components on your TV, like the T-Con board or backlight inverter, may get damaged, resulting in a black screen. In such cases, you need to take professional assistance and get it repaired. However, if you have some technical knowledge, you can correct the TV screen yourself by consulting our article on how to fix a broken TV screen.
Moreover, you don’t need to spend a penny on repairs if you are under the warranty period. You can even claim a new TV if a significant fault results in a black screen.

More than 500,000 Americans have now been vaccinated against COVID-19. In the next year, as more and more people receive their inoculations in the US, the vaccines will play a key role in helping the country recover from the pandemic. But vaccinating the entire country will alone not stop the pandemic. A global health event requires a worldwide response. However, the United States, once a leader in geopolitical affairs, has not participated in the international effort to make sure all countries are supplied with COVID-19 vaccines.
“The United States is not really helping to ensure that doses of the vaccine get to lower-income countries,” says Carnegie Mellon University bioethicist Danielle Wenner.
The COVID-19 Vaccines Global Access Facility (COVAX) was formed earlier this year by the World Health Organization and other international organizations to ensure that COVAX member countries would be able to pool their resources on vaccine development and all receive doses of vaccine. However, the United States—historically considered a world leader in international matters of this sort—is not a member of COVAX and is receiving its vaccines through a direct agreement with the companies producing the preventative drugs.
Remaining absent from this group will not only have a large effect on global vaccine access but it will also influence how long the pandemic persists, including in the United States. The US has a multitude of resources that could help global vaccine access and distribution and its participation in COVAX could help end the pandemic faster; simply vaccinating its own citizens won’t cut it. “It’s really not the case that you can eradicate an infectious disease in one corner of the globe,” says Wenner. “We can’t exist in a national lockdown indefinitely.”
Because the United States relies on international trade and travel to keep its economy afloat, the health of every nation around the globe influences the state of America’s health and economy.
The Trump administration said earlier this fall that it would be focusing on vaccinating Americans before “looking to do our fair share” for other countries. However, at this time there is no clear plan or commitment as to how that will occur.
COVAX plans to start distributing vaccine doses to its members in early 2023. The multinational group has contracts for up to 2 billion doses. Some of its 190 member countries, like Canada, also have direct agreements with vaccine-makers and are already vaccinating citizens. They’ll potentially also be sharing extra doses they bought directly from vaccine-makers with lower-income countries, according to principles established by COVAX.
In the United States, President-Elect Joe Biden has reportedly been in talks with GAVI, the public-private partnership that oversees COVAX. However, he has yet to formally commit to signing America up when he takes office.
Signing on may help the United States repair its fractured international reputation, in addition to helping end the pandemic faster. “The U.S. had a lot of soft power before the Trump administration came in,” says Wenner. “The Trump administration has been very nationalistic in its outlook. And that comes with costs.”
