Ok thanks, i will try a little of cleaning and also do some work with my electricity to put the input voltage 220V, i will cross my fingers, after all the hope is the last thing it dies if not repair as you said or work with 2/3 of the S9 i will keep you inform after i do that for anybody else that is presenting the same issues

The issue also is if i disconnect the other boards and leaving the one with the problem the behavior is the same keeps showing 0.0000

Ok thanks for the answer i miss the point sorry 1200W for 110V, i am currently using 110V

it has double input
1.- input 110V - 14A
2.- input 220V - 10A

i assume i can connect either 110V or 220V of course i am consuming more power at 110V

APW3++ provided by the bitmain site in fact i purchased the PSU with the antminer
