My MacBook Air's display is changing colors when tilting screen

Recently my Macbook Air 2018 started changing colors to a pinkish tint after I tilt the screen past a certain angle.

The problem started occurring randomly one morning after normal use the previous night. I have not dropped, damaged, or spilled anything on the laptop to cause this problem.

I had the motherboard replaced at the end of last year due to the laptop not turning on, however, according to Apple, this problem is not covered in the warranty and they are asking another $700aud.

If there is any information on this issue and possible fixes or home repairs that could be done, any help would be greatly appreciated.

Attached is a video of the issue. https://youtube.com/shorts/LqMJMeYMKN4.
