Why is my YouTube video blank? Sometimes your YouTube videos become black because something tiny on your browser is temporarily going wrong. It may be fixed by simply refreshing the page. Click the Reload button or icon on your web browser or press F5 on your keyboard to reload the video page. Then see if the video can play normally.
How do I fix YouTube black screen?
Why is my screen black when I watch videos? The black screen from a specific file could be due to compression issues, file format changes, corruption, virus attacks, or read/write errors. An ideal video repair software will work perfectly, and you end up viewing the video without any problem.
Why do I have sound but no picture on YouTube? Sometimes logging out of your YouTube account and browsing as a guest may fix this problem (worked for me once). Simply Click on your profile button at the top-right corner and select “Sign out” from it. Once signed out, try playing videos as a guest to see if the problem is fixed.
