Hi there all, My 2015 rMBP has developed a purple line about an inch and a half long that's visible when displaying black. Anyone else had his happen? Not sure how it's come about, I've babied it since I bought it, there's not a scratch on it. Still got a couple of years of AppleCare left so I'm taking it in Monday to be looked at - I assume they'll fix the screen under the plan? Having spent 1k on it less than a year ago, I'm quite (irrationally?) nervous on the outcome.
