Chosen Solution
Had to fork out £500 the other day to get my screen replaced as I dropped my laptop. I had important work due and it was Sunday during a global pandemic so needed a solution quick. Found a guy who would do it on the day which was lucky. I noticed first the camera quality/hue maybe seemed a little different but pinned it down to me being a bit nitpicky. But over the last couple of days I’ve noticed the MacBook logo on the bottom looks weird, as in the gap between the ‘mac’ and ‘book’ as seen in the pictures. As well as I keep getting these lines at the bottom of my screen that weren’t there at first. Everything else seems fine, its a metal lid with normal retina display. Any ideas? Also if anyone has a solution to fixing the lines that would be great.
The lines are a concern! The display the tech put in was likely from a used system which in its self is not surprising as Apple holds a tight reign on its parts. They don’t sell to independents, they only supply parts to their authorized service providers and their own Apple Stores. The quality of the display then gets into how heavy used the previous owner of the system the display came from. Sadly Apple had a design defect (in my option) in the newer 2016 > 2019 and it looks like the 2020 models still have an issue just looking at the construction which is basically the same as the 2019 models. So what is this defect? Apple wanted to make the display lid thinner! So they needed to re-arrange the placement of some parts. Taking them out of the lid and putting them into the main case. On the surface this is not that big deal but it has ramifications! In the older models a smaller cable was used to move the signals and backlight power from the main case to the lid. Here’s a 2015 13” retina
Now look at what yours is:
The larger purple marked cables are the ones going to the lid for the display. Now let’s look at this a bit differently The board in the middle is called a T-CON which was within the lid in the older 2015 and older MacBook Pro’s and now is held in the main case. This board really shouldn’t be cooked! But Apple placed it right in the middle of the hottest area within the system!
So if the T-CON gets a slow roast it degrades the capacitors and logic chips. This in turns create the lines you see. If Apple had thermally isolated the T-CON better this would not have been a big issue! So if this is something that bothers you, your only choice is to bring the system back to the person who did the repair and ask for a better part. The other option is to replace the display assembly on your own its not overly hard. But of course the trick is getting a good display! I find these folks have access to the ASP parts (new) as well as used TheBookYard UK - 2017 Fn Key displays then its just a matter of how much its going to cost you.
