Thanks for all the help. I learned a few things today.
The hardware warranty from 3DR Robotics is only 90 days from date of purchase
That I am 90% sure that the failing part is the TS5A23157, so since they are only $1.10 each from Digikey, I thought I would order 1 and replace it (plus $8 shipping)
I also confirmed that the problem is on the APM, as when I swapped it out for another one, it started to work. Many thanks for Zoltan at NG Hobbies in Toronto for lending me his spare APM to test with.
Once I have replaced it tomorrow, I will let everyone know if my final guess was correct.
