Hi,
My APM worked fine for 2 short flights at my yard.
On the third flight it just powered off after landing.
Now it does not power on from any ESC on connected to the output rail, only from USB.
What am i missing here ???

So first I must say WOW and big thanks to 3DR support.
I have decided to send my board for repair.
Sent email to 3DR, received email from them later this day with firstly saying they are sorry for the inconvenience.
They have supplied me RMA number, and offered to credit my store account for the shipping.
Malfunctions can happen, but eventually it’s all about customer service.
At this point I would say we need to ask 3DR to look at it.
It seems that this diode has a failure or just not the right components.
I have faith in the group that it can be resolved.
Had a flight this morning, tried to have another one later, but the board wouldn't power up at all.
Just checked now and the output rail is dead, it'll power up fine with 5V on the input rail. A couple threads mention a diode that may have gone, if this is case I presume its the diode next to J1 labelled B26.
If so what with what do I replace it, I see there's a few different types? (Please note I have the equipment and am fine soldering SMT components.)
What would cause this to happen, nothing has changed now after 100+ flights?
:(
I wish that was the case but everything in place.
I have dissconnected all, and connected it to one ESC and still nothing.
Sounds like your JP1 jumper fell off. Just place it back on.
