Good evening, marmadj!

It's a pleasure to have you at the Apple Support Communities. It sounds like you're seeing black horizontal lines on your display and I'm happy to help you resolve this.

A good first step is to reset PRAM/NVRAM.

Reset NVRAM or PRAM on your Mac

Additionally, you may consider booting your Mac to Internet Recovery (Shift-Option-Command-R: Mac startup key combinations ) to ensure that there's not a software component to these aberrant lines. Internet Recovery downloads a clean version of the installer each time, so, if you're still seeing lines on your display in Internet Recovery, you'll want to Contact Apple Support .

Best wishes.
