Hello guys,
I have a problem with my device which is Mi 9T. There was a green color line on the screen for some reason and later the screen was broken. I decided to replace it and when I put on the new screen it was like in the picture above.
Please help me what is the problem in my device is this related with flex or not

For laptops this kind of artefacts are often caused by damaged gpu.
In phones there is a video output chip, so my bet is motherboard fault, not lcd itself
