Wow sorry to hear that. I've had the same experience with my 15" MBP. Apple replaced everything apart from bottom case. The bottom case has no components. Despite that, the laptop died again (and several times since).
I live in Bali (Indonesia), there is no Apple store in Indonesia. The only domestic option is an authorized service center. A hardware replacement such as logic board or screen is a 5-6 week wait time. My laptop is my primary work tool. 5-6 weeks without income? So instead I've opted to fly to a city with an Apple Store and Genius Bar. So far I have flown internationally 12 times to get this laptop repaired. I'm compiling a list of all the hardware faults, days out of service and hours on calls to Apple and hardware faults and will take this to the consumer court in Australia which is quite effective usually. And, now the laptop has died again, it can't find the SSD. Trying to install OSX to an external USB also fails, implying another logic board fault.
I write this from a 2010 Mac Mini connected to a 2007 30" Apple Cinema Display, both work perfectly, not a single failure ever.
