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?
