Hi there,
'''Got a Purple MacBook? You Can Waste Another $700 Fixing It, Or JOIN OUR PETITION And Make Apple Take Responsibility For Their New, Faulty MacBooks. It's Time To Act Together:''' https://purplemacbook.com/

So, After owning MacBook Pro 15″ 2012 for a few years (loved it), and a bunch of other products (Apple Watch, MacBook Air, iPhone), I’ve decided to invest my earning in the new Macbook Pro 15″ 2017 with TouchBar.
What a stupid decision it was…
'''Because after a year, The screen suddenly showed vertical purple lines all over the screen, Just like that.'''
I protected and cared for this faulty laptop, and even though it NEVER fell or got any physical damage (No bumps or even scratches) – It got the purple screen lines disease.
My warranty/coverage was expired few weeks before the vertical purple lines occurred on my screen.
'''So, I did what every Apple customer will do. I went to the nearest Apple store and asked for help.'''
You can guess what they’ve told me (they probably said the same to you) – Your warranty is expired, there is nothing we can do. Replacing the screen is your only option, and it costs around $800.
