Suggested January 2024 How To Fix Black Screen On Roku Tv
If a black screen suddenly appears on your Roku TV, it interrupts your streaming experience. Several Roku TV users encountered a black screen with sound playing in the background, especially on TCL TV.
Usually, you get this error due to a minor power glitch or a loose connection. But, a major hardware failure like a damaged backlight inverter or LED strip can be responsible too. Some of the other possible causes are:
Faulty HDMI Cable or port
Enabled Sleep Timer
Auto Power Savings Mode
Problematic Apps
Outdated Software
Before you begin, you can perform a power cycle on your Roku TV when a black screen appears. Unplug the TV’s power cable from the wall socket and leave it for about 5-10 minutes. Then, plug it back in properly to see if it is gone.
If you are using Roku streaming sticks or other consoles, the HDMI input source must be correct. A wrong input source will show you a black screen. Press the Input, Video TV, Video, AUX, or Source button on your remote to change it.
Besides input, you can check if the video cable is loosely connected. Check the HDMI port and re-plug the cable to fit it perfectly. Besides, a faulty or broken video cable can also lead to a black screen while streaming on your Roku TV.
You can switch the cables to see if the cable is faulty. Also, if the HDMI port is not working, check out our other article on fixing the HDMI port on TV.
When you enable the Sleep Timer feature, it will automatically turn off your Roku TV after a certain preset time. If you have probably forgotten to turn it off, you will get a black screen when the TV powers off itself. So you can turn off the Sleep Timer to see if it is the cause.
Pick Off option.
When your Roku TV is idle, the auto power savings mode feature will automatically turn it off to save energy. It can be one of the reasons your Roku TV keeps turning off and shows a black screen. Therefore, you can disable this feature temporarily.
When you enable Fast TV start on your Roku TV, in-built speakers or wireless audio devices will stay connected even when your TV is idle. So, if you can hear the audio but on a black screen, it could be due to this feature. Try disabling this feature from your Roku Settings to verify.
On your Roku remote, press the Home button.
Choose Fast TV start.
If you get a black screen only while launching a specific channel, app bugs might be causing it. You can delete such problematic apps immediately to get rid of them.
Locate and highlight the Application.
On your remote, press the Star button.
Software issues could be another cause of the black screen error on your Roku TV. Usually, Roku releases new software updates to address such problems. So upgrading the operating system with the latest version should solve the error.
By default, Roku TV automatically scans for the latest software every 24 hours during an active internet connection. Although, you can also manually check for the latest updates from settings.
For users who are stuck with a black screen and cannot navigate through the system, you need to perform a hard reset on your Roku TV. Locate the Reset button on your TV. Then, insert a Paper clip inside the hole. Press and hold the button to trigger it. You can set up your Roku TV from the beginning.
Alternatively, you can also use your Roku TV remote to reset the TV.
If a black screen still occurs even after resetting the device, there might be a hardware problem on your TV. For Instance, the LED lighting strips might have been burnt. Or the backlight inverters might be damaged.
LCD TVs have a Backlight inverter that operates as a power source for the Cold Cathode Fluorescent Lamps (CCFL). It helps to produce a clearer image on the screen. Similarly, on LED TVs, there are LED lighting strips to generate images on your TV. But when such components are damaged, you will see only a black screen.
Replacing the part is the most effective way to fix the problem. If your Roku TV is LCD, you can replace the backlight inverter. Since most of the Roku TVs are LED, you can check out our detailed guide to replace the LED strips.
You can contact the Roku TV manufacturer’s support team as a last resort if the error persists. Customer support varies according to the Roku TV brand. So you can check out your brand and contact the support team from the official page.

How To Fix The Black Screen Of Death On Windows 10
Getting a blue screen of death is bad. But with it, at least your computer will tell you that there’s something wrong. On the other hand, if you end up with a black screen of death, you’re on your own. You’re left guessing what the problem is.
Let’s look at the causes and solutions on how to fix a black screen of death error on Windows 10. This way, you can resolve the issue without having to immediately ditch your computer.
Table of Contents
Find Out If Your Computer Is WorkingA possible cause of a black screen issue is that the setup process during a Windows 10 installation is not yet complete. If you have large data files from an earlier Windows installation, don’t be surprised if the setup takes up hours of your time.
If you didn’t know this, you must have went ahead and assumed Windows is already installed. If so, it must be the reason why you now have a black screen. The solution is to find out if your computer is still working.
Locate the LED that shows hard drive activity. Now, observe it.
If this light is blinking, it means the setup process is still ongoing. In this case, all you have to do is wait for it to finish.
If it’s not lighting up, it means the setup process is stuck, and it can’t proceed further.
Turn Off Your ComputerAs the setup process is not getting you anywhere, it means you have to try again.
Use the power button to turn off your computer. If it doesn’t turn off the way it normally does, press and hold the power button for about five to ten seconds.
Disconnect from the net by unplugging your Ethernet cable and turning off any wireless adapters.
Disconnect other peripherals, too. This includes game controllers and external hard drives.
Disconnect the power cord from your computer, too. Then wait about thirty seconds to do things all over again.
Reconnect the power cord, peripherals, wireless adapters, and the Ethernet cable. Turn on your computer and install Windows again.
Turn To Safe ModeTo boot your system into Safe Mode, start your PC and once you see the sign in screen, hold down shift. Then choose the power button and go with Restart.
Wake Up Your DisplayYour computer can also give you the black screen of death if Windows 10 isn’t detecting the display. The straightforward solution: force it to wake up. Just turn to your keyboard for this.
First, hit the Windows key.
Then hit ctrl, shift and B.
Reinstall The Video CardAnother possibility is a defective video card. What you need to do is reinstall it.
First, hit the Windows key and select Device Manager.
Update Your DriverIf your video card is not defective, it could be outdated. If so, it’s also a cause of a black screen.
To resolve this matter, go to Device Manager again.
Stop RunOnce ProcessesIf you get a black screen after you log in, the problem could be from a process that’s running.
To start resolving this, hit the Windows key and launch Task Manager.
You can also press ctrl and shift and esc. Doing this will also open your Task Manager.
For the change to take effect, restart your computer. You can do this by hitting the restart button.
Another option is to let Task Manager pave the way. To start with this, go to File.
Select Run new task.
There, key in cmd and press OK.
At the command prompt window type in shutdown -r -t 01 and press enter.

Fix Black Screen While Playing A Video On Windows 11/10
In this article, we will see what you can do if you see a Black Screen while playing a video on Windows 11/10. A black screen while playing a video means you cannot see anything on your screen but hear the audio and see captions (in some cases). If you notice such a thing on your computer, use the fixes explained here.
Why are videos showing up black?You may see a black screen while playing a video due to a corrupted or outdated graphics card driver, unsupported hardware (in case you are playing a high-quality video like 4K), etc. In addition to this, the black screen while playing the videos also occurs if the video codec is not supported by the media player. Whatever the cause is, the solutions provided below will help you fix this issue.
Fix Black Screen while playing a video on Windows 11/10If you see a black screen while playing a video on Windows 11/10, we suggest you use the following fixes to resolve the problem.
Install the latest Windows Update
Run Video Playback Troubleshooter
Turn on Accelerated Graphics
Install HEVC Video Extensions
Update or reinstall your graphics card driver
Try another Media Player
Let’s see all these fixes in detail.
1] Install the latest Windows UpdateFirst of all, make sure that your system is not missing the important updates released by Microsoft. Microsoft also recommends installing the latest Windows Updates. Open Windows 11/10 Settings, go to the Windows Update page and check for Windows Update manually. If an update is available, install it and then open the video. If you see the black screen again, the problem lies somewhere else. Use the other fixes.

Tv Won’t Turn On? Here’s How To Fix It
Your TV should turn on after pressing the power button on the remote. However, sometimes, the TV may refuse to turn on.
This issue primarily arises due to hardware failure rather than software issues. Your TV may fail to turn on even if a minor hardware component is faulty. Glitches in the power circuitry and loose cable connections are the key causes of the problem. But, there may be significant issues like a blown fuse or capacitors which may require further troubleshooting.
Luckily, there are a few things that you can look after yourself before taking it to a repair center. Keep reading to fix your TV that won’t turn on.
If your TV doesn’t turn on, it might initially seem like a massive issue. However, you don’t need to panic. Provided that there is no major hardware failure, a few troubleshooting techniques can help you get your TV back.
The issue primarily arises due to power glitches in the circuit board of your TV. You can perform a soft reset and solve the glitch in such cases. Most of the time, a soft reset will solve the problem without further exploration.
To do a soft reset, unplug the power cable from the supply. Wait about a minute. Then, press the power button on the TV panel for about 30 seconds. It will help drain the residual power from the capacitors and solve the power glitch. Then replug the cable and try to turn on the TV. It should solve the problem.
Since the problem is directly concerned with the power supply, you should also check if the power cord of the TV is connected correctly to the wall socket. You can try changing the power socket. You can use an electric tester pin to determine if the socket is faulty.
If you don’t have one, connect another device, like a phone charger, to inspect if the power socket is faulty. If it works, there is no issue with the power socket; the power cord or TV is probably faulty.
Likewise, if the power cord is connected to a voltage regulator, remove it from there and connect it directly to the wall outlet, as a faulty voltage regulator will also prevent the TV from turning on. Next, you need to see if there is any breakage in the power cord. Inspect it thoroughly. If there is any breakage, you can quickly get a replacement cord.
Most modern TVs utilize a voltage level between 110-240 volts to operate correctly. Anything above or below the level can cause issues, and you can not turn on the TV.
You can see your home’s electrical distribution box or sub-meter to know what voltage your TV is getting. If you are using a voltage regulator or a surge suppressor, it will also show the input and output voltage. If it marks a voltage of anything lower than 110V or higher than 240V, the TV may not turn on. You need to contact the electricity distribution center to sort out the problem.
If the cable connections and voltage levels are fine, the power cable connector may need to be correctly connected to the TV. Unplug and re-plug it. Also, see if any debris has collected over the port, as it can interfere with the connection. You can use cotton swabs to clean the port and cable connector.
There can be two cases when your TV doesn’t turn on. First, the LED indicator on the TV glows, but it won’t turn on, and next, neither the LED indicator lights nor the TV turns on. In the former case, chances are high that there is an issue with the TV remote that you are using to turn on your TV.
Please check if the batteries are correctly placed and are not dead. You can try replacing batteries and attempt to turn on the TV again. If not, you can also use the power button on the TV panel to turn on the TV. Moreover, if anything is blocking the infrared receiver on your TV or remote, the IR signals can not transmit correctly from the remote and cause an issue. Verify if that’s the case as well.
Please take off your TV from the wall mount or cabinet and remove its back panel with the help of a screwdriver.
Locate the power circuit board. It is the one that is connected to the external power cord. You can quickly identify it once you dismantle the TV.
Once you do that, it’s time to begin the test.
You should first check if the main board on your TV is receiving power from the power supply board. For this, you need a multimeter. Then, you can start the diagnosing process. You need to check the AC input on the power supply board as well as the DC output from the supply board.
The power supply board has two sides: hot and cold. We measure AC on the hot side while DC on the cold side. Be careful with the hot side, as you can get electrocuted.
A blown fuse can cause the power circuit board to malfunction. It commonly blows out when there is a power surge or lightning strikes. To know if a fuse is blown, inspect the thin metallic wire inside the fuse. If there is a gap in between the wire or a dark smoky substance inside the fuse, you can confirm the fuse is blown. In such a case, you need to replace the fuse.
You can even perform a continuity test to know if a fuse is faulty.
The capacitor is the next component that can get damaged in the power circuit board. Capacitors get worn out over time, causing the power circuit board to crash.
So how do you know if the capacitor is bad? Identifying a damaged capacitor is easy. Simply inspect all the capacitors in the power supply board. If you see any of the capacitors bulging from the top or a liquid (electrolyte) leaking from the capacitor, it is damaged.
Replacing a damaged capacitor can be pretty sophisticated, and you need professional help. However, if you want to replace it on your own, you need to get exactly the same capacitor from the market. The rated capacitance, temperature, and voltage of the new capacitor should be identical to the damaged one.
But we don’t recommend replacing the capacitor on your own, as a slight mistake may end up damaging the entire power supply board.
Now that you performed a power supply test and diagnosed the fuse and capacitor, you must have figured out what is causing the power supply board to crash. If you see everything is fine, there is probably an issue with the display panel of your TV.
Display components like the backlight inverter and T-Con board are most susceptible to damage. Or, in the worst-case scenario, the display panel or the main board itself might be blown out. Please consult with a professional to figure out the case. If you find that your display is broken, please consult this comprehensive guide on how to fix a broken TV screen.
If there is massive damage to your TV, and you plan to purchase a new one, please consult this article on what to do with a broken TV.
