Hello,
I tried powering on my MacBook Pro and Instead, these black and white popped up and after a while more began to appear. I’ve tried the CMD+OPTION+P+R and CMD+SHIFT+OPTION+POWER methods but neither has helped. How do I fix this?
That usually indicates a hardware issue with the built-in Display. You can confirm by connecting an external display and enable mirroring. If the issue only shows up on the built-in Display, then you will need to have the built-in Display Assembly replaced.
