Chosen Solution

I know this issue is becoming common on 2017 models and Apple still does not want to admit that this issue occurred due to the design flaw same as the FlexGate issue. My questions here are

  1. What is the main reason for this common issue?
  2. Is there any solution for this issue rather than a screen replacement?
  3. If I changed the screen would it 100% fix the issue or is there a chance that it may appear again because when I went to AASP they told me that they are not sure even with a screen replacement the issue would gone so I may even also go for logic board replacement (so basically I’m spending for a new MacBook Pro to repair mine)

NOTE : If I kept ignoring the issue, the lines not just become darker it even develops an image ghosting. Update (04/12/2020)

This is how the screen looks after I ignore the lines. Thank you Apple for your faulty device :)

You are facing a design choice Apple made that placed part of the displays logic within the main case. In its self that’s not a big issue, it’s where they placed it! So a part that needs to be kept cool is placed between two very hot heat sink radiators is not a good place! The double whammy is Apple also designed this system with the idea the 10 nm chips Intel had expected to deliver so the chip they had to go with runs hotter. We also add to it! We place out systems on our bed or other cloth surface which blocks either the side vents or rear exit vent, so the system cooks even more! Sadly, the part that cooks is the T-CON which is hardwired to the LCD panel you can’t replace it without replacing the panel which means you need to replace the entire assembly. There is no magic here sorry ;-{ You need a new display assembly. Sadly, the replacement part won’t fix the underlying issue. Your habits will though! Install a good thermal monitoring app like TG Pro so you can ramp up the fans, and of course keep the vents clear of anything that could block them. The last thing is not to push the system to the extreme. Make sure you have at least 1/4 of your drive free so your system doesn’t need to run wear leveling as often and you have room for virtual RAM.
