Something definitely happened to cause the power to kick out. Either the ASIC shot craps, or it's an issue with the power circuit itself. The ASIC shouldn't shoot craps unless it was run too hot. Is there discoloration on the backside of the PCB?
I don't see anything?
Sorry maybe not the best pics, I can try and take better ones tomorrow in daylight.
