MacBook screen flashes to white and grey lines?

Hello, my MacBook retina early 2016 has an issue where every 2-4 seconds the screen flashes to white and grey lines. After 1-2 seconds of the lines, it goes back to working normal for about 2-4 seconds before returning to the lines. It does this infinitely and won’t stop. The color of the lines changes with what is being displayed on the screen. I also hear a small buzzing noise when the lines appear near the bottom of the display around the left hinge. Does anyone know how to fix this issue? Thank you!

Soluzione Prescelta

Can't be 100% sure without tests, but it looks like a display issue. You can buy a Usb-C to Hdmi adapter to check the image is correctly displayed on an external screen or Tv. If the image is there, then a display replacement would be the most probable right solution. If on the external screen you have the same image as on the display, then you'd need a logic board replacement.
