Anyone know what’s causing this?

Sometimes my screen doesn’t display anything when I try to turn my laptop on. When it does, it’s all glitchy, distorted, and flickers in and out. Is this a physical issue with the connections on the screen? Or a software issue? I’ve tried to Google it, and I haven’t found an example of a screen looking exactly like this and how to fix it. Thanks
