FYI, I just got mine fixed at a MacBook Pro repair shop in Saigon, Vietnam (big shout out to Laptopblue.vn aka Applefix.vn). The most amazing thing was they found out that only the display cable was damaged, absolutely nothing was wrong with the LCD screen itself. They did a great job and my screen is working as good as new again. The cost was $50. Prior to going to this shop, I went to two Apple Authorized Service Providers and they both wanted me to replace the entire display assembly as some of you here had encountered. I suspect this was a strategy employed by Apple to extract more money from their loyal customers. Shame on you Apple!!! I will never buy another device from them ever again. I know some of you may encounter this issue in the future. You don't need to replace the LCD, you'll just need to fix the display cable. Don't give Apple $600 of your hard earned money. They don't deserve this.
Wow I just had the exact same issue on my MBP Late 2016 with Touch Bar now. This must be a common hardware issue with some of their Late 2016 batches as the pattern is clearly there. I'm just 2 months out of my warranty and guess how much they quote me to fix it? $600. We already paid top dollars for this supposedly premium hardware. Shame on you Apple! They had battery problem right from the beginning with this model but I decided to stuck around to support them. They would be crazy if they think they'll get more money from me. I'm moving to Dell XPS.
