Macbook Pro 15" 2016 scrambled screen
Hello,
So one of our 2016 Macbook Pro 15" with touchbar's screen got scrambled all of a sudden. Couple of vertical bars with scramble signals and flickering throughout the screen. It shows up even before the apple logo comes up at bootup and doesn't go away. Tried disabling GPU switching but that didn't help. Tried to performed the SMC and PRAM reset but it didn't work. Connecting to an external monitor, the video on the external is fine but the one on the laptop is still whacked. I've ran into this before with the 2011 iMac GPU issue and 2012 MacBook Pro. Anyone ran into this issue before and found a fix?
Appreciate any info but I have a feeling it's going to be an Apple store repair to fix the issue.
Thanks!
