Yellow stains on retina screen

[Laurens165]

Hello,

I'm not sure this is the place for this kind of queries, but my MacBook Pro medio 2017 has yellow stains on the side of the screen. These stains come and go as they please, it's a bizarre happening.
Is there anyone here who could clarify to me what is happening and what to do about it?

I've added some pictures of the occurrence.

2016-2018 MacBooks are trash. Take it to Apple and they should be able to replace it for you.

looks like bad screen assembly, warranty repair is your way to go

I when to an "Authorised Service Provider" where they replaced the screen. The replacement was within the warranty! I had to wait six days before I got a notice it was ready.

Thanks for the quick response Kiki and F23.
