Screen, motherboard or software issue?

I'm having issue with the display, the black background on the screen aren't pure black is like redish tone and it have like verticals lines that are visible on gray colors or on not to light background, they are visible on the camera as well, wen the camera is open and I move the direction the lines appears but like pink tone color. I need to know if I can change the motherboard or if its the screen or software. Similar to this
