Replaced defective logic board now the screen is white with lines?
I had a defective logic board that caused my mac to have no sound and it would randomly restart. I replaced the logic board and now finally have sound but to my dismay, when I booted to macbook, the screen was mostly white. I waited for the apple logo to show and it never did?
I noticed that if I look at my screen from another angle I can see faint lines so i had a hunch. I plugged my mac into an external display and it was on. So i figured that the display cable wasn't seated properly. Visually it looked okay and i reconnected it and still the lines? Also reset the SMC and PRAM?
Is this a good question?
