Hi, i have had my base model 2015 Macbook pro for a while now but only recently has my screen shown these problems. When the macbook starts the screen is normal with the exeption of a couple dead pixles, then after about 30-60Min use the screen gains a red tint, more dead pixels and at times red lines across the screen.
I have asked around but no one has been able to dirrectly identify the problem, i assume its a screen problem an i intend to replace the screen myself but before i spend $500 buying the part i would like to hear your opinions to what it may be. Through my knowledge so far it could be either be a screen problem or a gpu problem. Thanks.
While your screen may need replacing do to the dead pixels. I don’t think replacing the screen will fix your color shift issue. Lets do a bit more diagnostics here. Connect an external display via the mDP/Thunderbolt connection. Do you see the color effect on it if not then its the display alone, If you see the artifacts on it then the main logic board has failed and will need to be replaced. You might find replacing your system a cheaper option if both need replacing.
