Horizontal line on bottom of MacBook Pro 2017 (Due to overheating)
Long story short- I share my laptop with my room mate. My room mate confessed to me that she was using the laptop on her bed, over the sheets with the power adapter plugged in. She said that the machine got really loud (I guess the fans or whatever were going off)
Later that day I noticed that there was a black line below the app menu on the bottom. It was weird because I would move the cursor over it and you could see the cursor. I have ran NVRAM and SMC and it hasn’t fixed the issue.
However, we left it shut down over night and it was ALMOST completely faded in the morning (though with use the lines would eventually come creeping somewhat back but not as bad as the first day.)
I don’t want to be super hasty and assume I am in for a $500 repair. I have seen similar posts on here where people had the same issue and they said that the lines eventually went away, or that after a week of not using the laptop they got lucky.
Has anyone gone through this? Is this something that will get worse over time?
Is it possible the over heating caused one of the cables to come loose inside the computer? I was thinking of opening up the laptop and reseating the display cables.
Does it ACTUALLY need a replacement or is this something that will go away with time/can be solved by opening up the macbook or leaving it off for a while.
As is the case with most people, I don’t have the money at the moment to handle what would probably be an expensive repair.
I would complain about how the computer is only two years old but I am pretty sure its my room mates fault for the overheating lol.
If any of you have any suggestions or similar experiences I would really appreciate it.
Thank you for your time.
Thank you for your quick response!

(Day of the heating issue)
You can barely see it. Its just a bit brighter down there than the rest of the screen.
Though I am sure they will probably get stronger with usage. I think it was on another forum but a few people had said they left it alone for a couple of days and it got better.
Thanks again for your time with this.
Can you post a picture so we can see what you are seeing 在已经存在的问题里加入图片
Until we get an idea on what you are facing I would hold off opening your system as you could make things worse!
I'm not sure where you saw lines fading in and out here. I don't remember seeing anything here on iFixit.
Often times lines are TAB connection issues when the mounting of the flex ribbon to the LCD panel has broken free. Often due to a bang or something heavy sat on the lid.
The other possibility is image persistence (image burn-in) where the LCD crystals have fatigued from being held active overly long. There are some tricks that might reduce the effect.
The pictures will help us understand which one.

I had this problem 2 Months ago.
it is not because of the Display at all.
It is Logic-Board Problem.
They replaced it for me!
Be aware it is not Display Problem at all!

It is because of the logic board indeed but the T-CON logic board of the screen, which requires a swap of the display assembly, not the motherboard. So...

Have the same issue with my 2017 MPB 13 inch!! Should Apple not be responsible for this? Kinda expected a 2k+ product to last more than two years…

Turns out, heatlines are also fixable with replacing thermal paste and fan cleaning if the damage isn't severe. I published enhanced guide on this ?https://meiokubo.medium.com/guide-for-re...
