Hy everyone I have a A741 and last week the source and the power cable is burnout .
the all 6 pci-e are burnout on the Avalon, but the Bitmain source is ok.
After i put the A741 on the power in the controler board is see : not any device.

I don't have an AUC3 to replaced, i don't have any board to tested.
The led is RED on the board on back miner, on the PMU board the led is Green (on the PCI-e power.) 2 led on the side .
pls help.
No smel , no burnout component on boards, all it is ok visual.
