Do you have a second board to test that was never powered up with the VREF error? I've never used the Arria V so can't comment on that specifically. Just tossing out a general troubleshooting approach.

hello rsefton,
thank you for your message.
we have a second board... but we are afraid to use it as we are not sure to understand the problem.
we had to remove the FPGA of the 1st board to be able to see the right power supplies sequence...
thus, we lost for sure the FPGA but maybe also this board in the removing process.
but you're right, at the end, without any clue, we will power up the second one after fixing the Vref issue.
