If you are experiencing black screens while trying to view a video, the best way to troubleshoot the issue is to first check the video source. In most cases, the video file itself, or the streaming service it is coming from could be having issues.
If the source appears to be working and the same file is displaying correctly on another device, then the chances are that the issue is with the device you are trying to watch the video on.
If the source video appears fine on another device, then it is likely that the issue is with your device, and you should restart it or check for system or driver updates that may resolve the issue. If you are still experiencing problems, then you should contact the device manufacturer for further help.
If restarting your device does not work, you may want to try different apps for playing the video, as other apps may be better able to render the video correctly. Additionally, you may want to try changing your display or video settings from the device’s Settings or Preferences menu.
If none of these steps work to resolve the issue, then you may need to contact the device manufacturer for further help.
Why are my videos black on my phone?
There are a few possible reasons why your videos might be black on your phone.
First, the video could be corrupt. Videos that have been downloaded from the web or transferred from other devices may not be properly coded to play on your phone. Try re-downloading any external video files and transferring them to your device again to see if that resolves the issue.
Second, your phone’s video player app could be outdated. Make sure that your phone’s video player app is up-to-date. If you have an older version of the app, the video file may not be supported.
Third, make sure your phone’s software is up-to-date. If your phone’s operating system isn’t up-to-date, your phone may not be able to read certain formats of video. Check to see if your phone has any available updates that might help resolve the issue.
Fourth, check to see if your phone’s memory is too full. If your device is low on storage, it may prevent videos from playing or cause other performance issues. If your storage is low, try deleting some unnecessary files, photos, or apps to make space.
Finally, if none of the above solutions help, try using a different video player app. Some video players are more capable of playing different video formats than others. Try searching for a new video player app on your phone’s app store to see if that solves the problem.
Why does my iPhone go dark when watching videos?
Your iPhone likely goes dark when watching videos due to a setting called Auto Lock. This setting causes the screen on your device to turn off after a certain period of time of inactivity to help conserve battery life.
To turn off Auto Lock and make sure the screen stays on while watching videos, go to Settings, then Display & Brightness, then Auto-Lock. From there, you can choose your desired amount of time for the Auto-Lock feature.
Why are my iPhone photos turning black?
This is a very strange issue. There can be several possible causes for it, including a hardware issue, software issue, or even a battery issue.
If it’s a hardware issue, it could be related to a defective camera, lens, or even the external flash. To determine if this is the case, you can try examining the hardware for any signs of damage. If you see any signs of corrosion, smoke, debris, etc.
this could be a sign of a hardware issue.
If it’s a software issue, it could possibly be caused by an issue with the app or operating system. This could be caused by an outdated version or an incorrect configuration of the app or operating system.
To check this, try updating the app and iOS to their latest version, as well as any other app or software related to the iPhone.
If it’s a battery issue, it could possibly be due to a weak battery. Weak batteries can make it difficult to take photos, as the phone may not have the power to keep taking photos correctly. To check this, try charging the iPhone and seeing if the photos turn back to normal.
Overall, this is a strange issue, and hopefully one of these solutions will help fix it. If none of these solutions resolve the issue, please contact Apple Support for further assistance.
Why does my iPhone video have sound but no picture?
Firstly, make sure you have a steady WiFi or cellular Internet connection. If you are connected through WiFi, try disconnecting from the network and reconnecting. If you are having trouble with your cellular connection, try enabling/disabling Airplane Mode or turning your cellular connection off and on.
It is also possible that the issue is related to software on your iPhone. Try restarting your device. If that doesn’t work, you may want to try resetting all settings back to default. When you reset your settings, be sure to back-up your important data before you start.
If the issue persists, try doing a full factory reset, though you may not want to proceed with this if you have important data that is not backed up.
Lastly, there could be an issue with the video itself if it is a file downloaded from an external source. In this case, try downloading the video from a different source, if possible. If you are still having trouble playing the video, try playing it on a different device to confirm if the issue is with the video itself or with your iPhone.

Why is my screen suddenly black?
There could be a few reasons why your screen has suddenly gone black. First and foremost, it could be an issue with your monitor. Make sure it is securely plugged in and that all the connection ports on it are firmly secured.
Additionally, if you have an external monitor connected, try disconnecting and reconnecting it, or double check to make sure it is powered on and configured correctly.

Additionally, try using the built-in system diagnostics tools to identify and resolve any issues.
In conclusion, there could be several reasons why your screen has suddenly gone black. Make sure the monitor is plugged in properly, check the graphics card and its drivers, and use system diagnostics to troubleshoot any operating system issues.
Why is my computer turning on but no display?
One possible issue could be that the connection from the monitor to the computer has become disconnected. Check to make sure the monitor power cord is securely plugged into a power outlet and then ensure the connection from the monitor to the computer is secure.
A second possibility is that the monitor itself is not functioning properly so you might try connecting a different monitor to the computer. If you do not have a spare monitor, try connecting the current monitor to a different computer to check if the display works.
Another potential cause could be a malfunctioning video card. If none of the above troubleshooting steps solve the issue, the video card might need to be replaced. Additionally, the problem might be due to a faulty RAM module.
Make sure to check the RAM slots on the motherboard to ensure the memory modules are fully inserted and no dust or dirt is blocking the connection.
If none of these troubleshooting steps work, the issue might be with the motherboard or power supply. If that is the case, it is best to consult a computer repair specialist to diagnose the problem and recommend a solution.
How do I reset my monitor?
To reset your monitor, you will first want to make sure you are working with a monitor with a power button. If your monitor does not have a power button, then it is important to consult the user manual to understand the proper procedure.
First, you will want to turn the monitor off. This could be done either by pressing the power button on the monitor itself, or by turning off the power switch on the power cord for the monitor.
Next, unplug the monitor power cord from the power outlet. You should leave it unplugged for several minutes, which will discharge any static electricity in the monitor.
After a few minutes, plug the monitor power cord back into the power outlet and power the monitor back on.
Your monitor should now be reset and you can begin using it again.
Why is my phone working but the screen is black?
If your phone is working but the screen is black, there are likely a few possible explanations. The first is that your phone’s display could just have a problem. This could be related to the display itself or its connection to the phone’s mainboard.
In this case, you would likely need to bring your phone to a specialist for repair to address and replace any faulty components. The second is that the display may be disabled. This could happen if the settings of the phone have been changed so that the display is off, or if the phone has gone into an energy saving mode.
In either situation, the hardware of the phone should still work, although you may be unable to interact with it if the display remains disabled. To address this, you can restart your phone from the external devices and reset the setting.
If your phone’s display is neither broken nor disabled, then the issue could be related to the software. This could be that the phone’s operating system was recently corrupted or is otherwise malfunctioning.
To eradicate this issue, you can try performing a factory reset of the software. This should correct any errors in the system.
How do I reset my computer without display?
If you are trying to reset your computer without display, you will need to access your system setup. Depending on your computer model and setup, this may vary. Generally, you will need to restart your computer and access the setup screen by pressing a keyboard command such as F2, F10, or F8.
Once you are in the setup screen, you can locate the reset or restore option. Make sure that you have backed up any important documents and data before resetting your computer so that you don’t lose anything.
You will likely be given options for resetting either to factory settings or to a pre-saved recovery point.
Select the desired option, save any changes and restart your computer. Your computer should be reset to the specified settings and your display should be ready for use. If it still does not work, contact your computer manufacturer or a specialized technician for assistance.
How do you force a computer to start?
In order to force a computer to start, you must find the power button and press it. Depending on the type of computer, that button may be on the front of the computer case, or on the top or side. It’s simple to do, and it is usually the only solution for getting a computer to start if it is not responding to any other interaction.
Some computers may have a slightly different method for initiating a startup, such as a power switch on the power supply located on the back of the system. Once powered on, the POST (Power On Self Test) should initiate, which typically includes a series of beeps and audio and visual alerting.
Once successful, the computer should begin its startup process, including loading its BIOS (basic input/output system), and then loading the chosen operating system.
Why is my video showing a black screen?
The most likely cause is that either your video file format is not supported or the video is incomplete or corrupt. If the video was taken on a digital camera, make sure you have the right media player and codec installed on your computer as some camera video formats are not always compatible.
Additionally, make sure all the necessary plugins and codecs are up to date and functioning correctly. If the video was downloaded, check to see if the download was successful and the file is complete – partial video files won’t work.
You could also try playing the video on a different media player. If the video is stored on a USB flash drive or external hard drive, try transferring the file to your computer and playing it from there as these types of drives may not always be compatible with the media player you are using.
If all else fails, try re-downloading the video.
Why is MP4 not showing video?
The most common is that the file may be corrupt or not encoded correctly. Additionally, the incorrect media player may be selected to play the file. The MP4 file extension is very popular and is supported by many media players, but not all can play all variations of the MP4 format.
Therefore, it’s important to select the right media player and the right codecs, so that the video can be displayed correctly. If none of these things are the issue, then it’s possible your computer does not have the appropriate video and audio codecs installed, which are necessary for playing the file.
You may need to install the necessary codecs in order for your video to display correctly.
