MacBook Pro won’t turn on, even after SMC reset
The answer in my case was No, there was no other option but to change the main logic board. To my extreme fortune, Norwegian law requires five years of warranty on all electronics such as laptops and phones, so it was done for free. The repair shop even told me I was eliglible for a new screen so they threw in that as well.

Update Q1 2018: And to my extreme fortune and several unexpected circumstances, now they even swapped out the battery for free. Talk about longevity :-)
