I have here a 12 ″ MacBook which draws some very nice patterns on the screen. Basically the same problem as here.
From my research, it is a ribbon cable or a fried TCON chip (“Timing CONtroller”). Video on an external monitor is flawless. What do you think?
The machine has been retired in favor of my M1 MacBook Air and I want to fix it myself for fun, it’s not a big deal if I get it wrong.
