Hello, i'm facing some issue with my antminer s7, it doesn't hash. I've tried upgrading firmware, but still no response.
Little help would be welcomed.

Thanx, but i still face the same problem...
Any ideeas how i fix it?

Nothing just jumping out so far.  What PSU are you using on it?   Also are you able  to take a screenshot of network page I'm just curious to see what's in there?  And did you use right firmware for your S7 some batches had different frequencies at beginning, so just making sure you used one for your's did not grab a random one.

It's kinda guessing with nothing jumping out wrong.

Are you using a valid username and worker name for kano's pool? I am not even sure if that would prevent you from submitting shares, but kano would know for sure.

If the username and worker name is invalid it won't work on Kano.
Otherwise, not sure what your problem is since I can't see what your using for user/worker.
Good luck.

EDIT: That's a hell of a lot of HW errors for just 10 minutes. Something is definitely wrong.

Put Antpool an first place, and everything works.

Great suggestion, for average results lol.

I've tried to put it in antpool, still same response. It's 4,73Th/s so the freq should be 700M, the firmware should be correct.
At the moment i'm running it on HP 1000w PSU, they are completely fine, i've tested them on another S7, working fine.
Thanx for the ideeas.

Any ideeas in order to solve my problem would be welcomed.

Reset it using the button.  You'll have to reconfigure everything but it looks like that would be the next logical step here since nothing else jumps out as obviously wrong.

Out of curiosity, have you disconnected the hashing boards and tried them one at a time?

Good ideea, i didn't do that.
I'll try it as soon as possible ang get back with an answear
