My 3 months old latest ver. duet 2 wifi worked perfectly since last night. Suddenly, the board went off. I switch off and on the power supply. The board is not turning on.
Then I connect the board and PC with usb cable. The board works again. But as soon as I unplug the usb, the board goes off.
With power supply connected only. Only the green VIN led is on. I can only detect always on fans have a reading of 24V. Nowhere else has voltage reading.
I tried to connect the on-board micro usb with a 5v power source (Not a PC). The board works.
What could be the problem with my board? And any suggestion for how to fix it?

If it works from USB it could be the black square chip labeled U3 has failed, take a close look at it, About 2cm in from the fuse between Vin and Bed output.
