I'm one of the many with a 2011 MBP that has display shutting off randomly and often with no way to turn it back on without shutting down the machine. Apple Store said it was a logic board problem and google searching seems to show this as a faulty part that shouldve been recalled but never was acknowledged by Apple. I see several cheap repair places online that offer repairs for $100 but the parts themselves are several hundred. What are they doing that I could probably do myself that doesnt cost so much? Has anyone else found a fix for this? replace the logic board? resolder something?
