I think my Netduino Plus 2 may have developed a terminal condition. When I plug in the USB connector, the white power light comes on but there is no blue light and there's no activity on the USB bus.

 

Does this mean that my ND+2 has ceased to be? Can I resuscitate it?

Sorry about the typo in the thread title. I think my distraught emotional state must have incapacitated my typing ability :P Unfortunately there's no way to go back and edit the thread title... Moderators?

Is there any program loaded? Try delete it or write a simple blink. 

Maybe it could be the LED. See if the pins work.

There was a program loaded, which should have controller a stepper motor and accepted network connections. No sign of any life there. I've tried the "complete erase" by connecting 3v3 to the gold dot, the thing doesn't respond to the USB cable being plugged in (the PC isn't seeing it). It doesn't show up in MFDeploy or DFuse.

 

I think it is probably dead. I forgot to mention in the original post: I have had a Netduino, a plug-top power supply and a PC power supply all fail at the same time. Oh, and my mains RCD was tripped. I suspect the PC power supply is what went, taking everything else with it. Drat.
