Unlike the older MacBook’s which used LVDS signaling the newer retina systems use iDP signaling which is a very different signaling system. So the symptoms of colored bands and screens for a bad cable don’t show up here. This system is either a bad driver within the display or the logic board’s GPU logic.
-What happens when you use an external display does the external exhibit the same behavior? If it does then the GPU logic needs to be looked into (likely needing a new logic board). If on the other hand the external display looks OK and the internal not the damage is within the display and would need a new display assembly.
