Suggested January 2024 10 Ways To Fix Black Screen Of Death On Samsung Tv

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 Nonetheless, poor cable connections, overheating, outdated firmware, or damage to display components are also possible reasons behind the issue.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.

How To Fix A Tv Picture That Is Too Dark Screen On Full Brightness?

The brightness level set on your TV determines the visibility of pictures on the screen. But it can be problematic when you encounter poor visibility despite setting the brightness to its fullest.

There are many other things, except the brightness level, that you need to adjust correctly to enhance the clarity of the picture. That’s why setting the brightness level to the fullest may not always work.

Most of the time, the issue can be solved by disabling the ambient light settings and power saver mode. Or picture settings like backlight levels and local dimming need to be adjusted. Nonetheless, your position while watching the TV and a bad source device also makes a difference.

If the brightness on your TV is not enough, even at full brightness, chances are there that you are watching TV from an incorrect angle. The viewing angle of the TV also determines the intensity of illumination on the screen. Meanwhile, ensure no direct sunlight is interfering with the TV screen.

Likewise, the source device can be problematic too. If you are watching TV via HDMI mode, consider switching to USB and see if the issue persists. If you face a problem only on a single source, there must be an issue with the source device rather than the TV.

The fixes discussed below need you to navigate through the TV settings. Therefore, if you have trouble navigating through the TV settings because of low brightness, you can make your room darker by turning off all the lights and closing the curtains of the room.

Most modern TVs incorporate a picture test feature that lets you diagnose any issues in the picture. It helps to determine if the problem is with the content you are watching or if the TV itself is the culprit. There is probably a hardware fault if you face a brightness problem on the test image too. Otherwise, adjusting the picture settings will help you get the brightness back.

Picture tests can be easily accessed from picture settings on your TV. Here, we are referencing Samsung Smart TVs for elucidating steps.

Smart TVs can adapt to suitable color settings depending on the lighting conditions of the room. There is a specialized light sensor on TVs that help them with this.

For instance, the brightness of your TV will automatically increase while watching in a dark ambiance and decrease while watching in a bright room. It can cause difficulty watching TV when you are in a bright room. Meanwhile, sometimes the sensor can go wrong and cause issues.

Therefore, disabling the ambient light settings can be a good idea to get rid of the problem. Here’s how to disable ambient light settings on Samsung Smart TVs:

Open TV Settings and choose General.

If your TV is in power-saving mode, it can reduce the brightness of the TV screen to save up some power. While this is useful for conserving energy, it can create difficulties in watching TV. So, please check if you have enabled the feature and consider disabling it.

Launch TV Settings.

Choose General once you open the Settings window.

You can’t just expect a bright screen by increasing the brightness level to the fullest. Other color settings like contrast, color tone, backlight levels, local dimming, and gamma function need to be adjusted accordingly to get the best picture out of your TV.

Please follow the steps below to adjust the color settings on your TV.

Launch Settings on your TV and select Picture.

It might be helpful to reset the picture settings if you are unaware of the best color levels to set on your TV. Resetting the picture settings will help revert every customized picture setting to default values. You should no longer deal with brightness problems after a picture reset. It can also help if misconfigured color settings are causing the brightness issue.

Choose Picture.

Let the reset complete and see if the problem persists.

You can also reset the entire TV as a last resort to sort out the problem. You need to move to hardware fixes if the TV reset also does not solve the problem. You can generally reset the TV from General Settings. Let’s have a look at how to reset Samsung TV to its factory defaults:

Go to TV Settings and choose General.

You might need to enter a PIN code to complete the reset process.

The fixes discussed above should sort out the problem if misconfigured TV settings were causing the issue. However, if you are still unable to get desired brightness on your TV, probably a bad backlight is the reason behind it.

Backlight strips behind the display panel act as a light source for producing pictures on the screen. But, if any of the strips malfunction, an inadequate light supply can lower the brightness levels on your TV.

You can first perform a flashlight test and determine if the backlight LED strips need replacing. Replacing LED strips can be pretty technical, and you should consult a professional technician to get it fixed. However, if you want to replace the strips on your own, you can consult our detailed guide on replacing LED strips of a TV.

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.

Faulty PSU

GPU issues

BIOS settings

How 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.
