Why is my display turning blue/purple/pink?

Hi, my display issues started several months ago. I had a vertical pink line across the the right side of the screen. Soon blue-ish and pink flickering bars appeared on the screen, and soon after the display totally crapped out and I only see black (with the back light on). Eventually I figured that be manipulating the screen, I could restore some function and currently my screen is blacked out on the right hand side, from where the original pink line began.

I’ve hooked up my computer to an external monitor and it works just fine.

What do you think is the issue? Is is a display issue and I should get a new screen? Or is is a logic board issue?

Answer this question I have this problem too

Is this a good question?

berelg770 this “manipulating the screen, I could restore some function” appears that you are having issues with the LCD display itself. You did not tell us how you manipulate the screen to make a determination if it is the cable or the driver board that may cause this. Ultimately it seems like you will have to replace the LCD assembly.

REmember “Before starting this procedure, you may want to check with Apple to see if you qualify for a free repair. If your display’s backlight has stopped working, or the display shows vertical bright areas along the entire bottom of the screen (a.k.a. “stage lights”), your MacBook Pro may be eligible for Apple’s display backlight service program.

For your safety, drain your MacBook Pro's battery below 25% charge before starting repairs.”
