Logic Board on a 5-year old MacBook Pro
The logic board was finished and simply required replacement. At first, I thought it was the graphic card because there were green and grey lines on the screen. However when the MacBook did restart as it should, Apple confirmed the problem.
The repair was smooth. I gave it to the right people and they removed the old and replaced it with the new logic board I purchased from IFIXIT.
IFIXIT gave me the assurance to guarantee the unit. I could have purchased it from anywhere else, but no one was willing to give me the coverage IFIXIT provided.
