Red blotches on MacBook screen

[vs4drutg]

Hi all - new here.

I've posted this on the apple forums also, but thought I'd post here too incase anyone can help!

Basically, when my screen is on a black background there are weird red blotches running across my screen - these disappear on a white background.

I'll add some pictures below.

It's starting to get quite annoying now! Anyone come across this before or have any ideas what causes it?

Cheers guys.

I think my screen did that (before it had to be replaced due to a traumatic hit right beneath the Apple logo). Mine wasn't red it was more of a yellowish color.

I have a feeling something is getting in behind the Apple and causing the discoloration. Either that or the logo is putting pressure on the LCD display. Push on the Apple and see what happens. Check to see if your Apple logo is getting loose. Mine is a late 2008 unibody Macbook.

I have a similar tint showing on my macbook 2012. It happened overnight and nothing was placed on top of the screen or anything weird like that. Did you get yours fixed @vs4drutg?

Yeah, same here! Anyone found out why is this happening? Any fix for it?

My MBP mid 2012 just developed the same symptom out of nowhere. But I suspect heat damage as I was using the macbook in clamshell mode for almost a week without opening the lid.

i pulled out my macro lens and found out some interesting stuff.

turns out the reddish tint is a defect in the red pixels, and only just a smallest spot at the top right corner (see attached image at 100%)

there are few reports of this on here, apple forums and reddit, but nobody was ever able to get to the root of why this happens at the first place, right?

the horizontal part doesn't match up with the space key, but perfectly with the edge of the sloped part of the upper case below the space key. that's why I suspect that the hot aluminium of the upper case may have transferred too much heat onto display.
