Graphic Issues on MacBook Pro Early 2015

Hello everyone,

I purchased my Macbook Pro Early 2015 last year and in such short time I have been to the technician 3 times, the first two to claim the warranty for the screen coating coming off and the third one due to a graphic issue that started to happen frequently.

Whenever I am trying to log in, I get a fast blink with a lot of neon colors, or the screen turns completely purple, I called Apple support but since I was never offered Apple Care they can't do anything to help me and the even tho the technician was able to see the issue, the apple tools were not able to detect any -problem-.

Have any of you experienced something like this?
