What is causing my MacBook to display vertical pulsating bars?

My screen has started to display multiple vertical bars that pulse and disappear every 5 seconds or so. The screen will freeze during the pulse and then functions normal again until the next pulse.
Seems like a physical issue. Does anyone have any recommendations on what to try before I open the MacBook?
