Chosen Solution
Hello People, my Girlfriends Macbook Pro 15” (2017) started showing problems yesterday. She flipped the display open and suddenly horizontal flickering lines and a big green bar on the right hand side of the screen appeared. Additiononal to that there’s a noticable noise coming out of the body of the compter - from the hinge, on the left hand side. The lines fade at a certain angle, with the noise still noticable. This leads me to believe theres a problem with the connection, hence the buzzing noise. I’m pretty angry because of this issue. Now that thing breaks? After 1,5 years of idling - once corona condemned us to home-office it just breaks? What the !&&*? Thankfully I’m in europe so we’ve got a two year warranty for every product purchased. I only need to file a formal complaint with the shop I bought this machine from and proof that this is an issue that was caused through normal use. Is there anything that would help me with this? Would an authorized technitian confirm that to me? Because: The stupid machine actually never left the desk, shows almost no signs of use and has been carried arround in a padded bag on a maximum of 5 occasions. If this causes internal connections to loosen, it’s just bad design. Plus: Through a quick research I see the same problem appearing more frequently in forums over the course of the past months. People keep describing the aforementioned issue. I’d say that there’s another design flaw apple has to deal with through a replacement program. Update (31.03.2020) UPDATE: I searched the web for the prevalence of this particular error in 2017 15” Macbook Pros. So far i found these threads: https://de.ifixit.com/Antworten/Ansehen/… This thread is dealing with the 13” Version but over the Course of the past months some people with 15” Macbook Pros reported the same issue. https://de.ifixit.com/Antworten/Ansehen/… Update (03/31/2020) Here’s some images and videos with the problem.
Update (31.03.2020) Here’s a picture of the screen without lines when not fully opened.
Update (31.03.2020) I’m pretty certain one of the cables connecting the t-con board with the display loosened or broke. The buzzing noise could indicate a short circuit.
Well not good ;-{ The T-CON is in trouble this is the part that sits inside of the main case. It’s located is a hotter part of the system between the two heat transfer fins of the heat sink. So any blockage in the vents (sides and back) can cause things to overheat.
To add to this running heavy video work can saturate the systems cooling system. I do strongly recommend getting a good thermal management app like TG Pro I’m not sure if you also have a display issue as well. While you likely didn’t bang the system given what you stated. You may have caused a problem during your cleaning of your displays screen. I’ve seen a few systems damaged by cleaning liquid dripping down into the electrical connections. This is most of the time due to spraying the cleaner onto the glass and then wiping the screen. The better (safer) way is to spray the towel/cloth and then wiping the screen. In either case the solution is the same replacing the display assembly MacBook Pro 15" Retina (Late 2016-2017) Display Assembly and here’s the guide MacBook Pro 15" Touch Bar 2017 Screen Replacement
It appears to be an issue with the built in display.
