My Late 2011 15'' MBP recently failed for the second time with the infamous GPU issue. The first time was in February 2015 so Apple repaired it for free, but I'm out of luck this time as the repair program is now over. The price I was quoted was close to 500 EUR for the replacement, which I don't feel like investing in a machine this old. Question is, has anyone been able to repair the logic board themselves? Or maybe buying a board only from somewhere and replacing the old one? Ifixit has a guide but was wondering if people had their own experiences with this already.
