Go the RMA route so it can be looked at.

Hi,
Similar to a couple of older threads I've found on searching, one of
my BBB's (a rev B) has recently stopped powering up from VDD_5V
(either the barrel jack or P9 connector).
Not sure what might have triggered this, nothing had changed in
hardware setup for some time, power was permanently supplied from a
5V wall wart and it was being cleanly shutdown from software each
day, and restarted from the on-board power button. Only things
connected were ethernet, a USB RF dongle, and a hall effect sensor
(powered from VDD_3V3B). Have since removed everything, and just
attached a serial debug cable.
Timing to failure is a bit variable, from nothing at all, to a brief
flash of the power LED, to getting several seconds into boot before
it dies (have also tried running from a bench supply, but just the
same results). I suppose the PMIC is shutting things down for a
reason (it draws no current in this state), but it is still working
fine from the USB_DC line.
So I'm a bit stumped. Any ideas, or should I look for an RMA?
Thanks in advance,
Jon
