BeagleBone Black died...

[Robert Heller]

For some reason my BeagleBone Black died (no flashing blue LEDs) sometime
early this morning. It had been running for a week or more, quietly flashing
on my workbench. I have not begun to do much testing (on my agenda for
today). It there anything I should be looking for?

Some basic voltage measurements on P9 (relative to 1,2):

3,4: 0
5,6: 5V
7,8: 1V
9: 3v
10: 0v

(This is with a 5V PS plugged into the 5V barrel jack.)

Looks like the Power Supply circuit died...

Hi Robert,

Here are some initial troubleshooting ideas, you may have already tried these:

Does pressing the power button (the button closest to the Ethernet socket) make any difference to the voltage at pins 7,8, even briefly?

It may be worth testing with no boards or other devices attached, just in case.

Finally, although you're seeing 5V from the PSU, it could be worth trying a different one (or trying to power the BBB from the USB connector via your PC) just in case there's some strange issue with the 5V supply collapsing under load.

I tried from my PC via USB. Nothing happening. I will try pressing the power
button and checking the voltage.
