But the problem is that one card of one of S3's is not working at all!

I have checked everything power, cabling, anything I can imagine but it persist and not working at all!

Any ideas what should I do?

Did you try moving the cables to the other ports?

Otherwise,  I would open it up and look for any loose connections. Sometimes things get knocked loose during shipping.

Yes, tried it and open it up as well but found no problem yet!
Checked the controller cable, changed it with the other one! But absolutely nothing happened yet!

It happen during shipping with one of my S1, check for any loose capacitors or inductors on pcb.

there is no shipment problem seems on the device.
But I found a clue.
I connected control cable from main-board Socket-1 to Board 2 and from socket-2 to Board 1.

Now the other board is mining and it's temperature increased.

So it's obvious that there is some problem in mainboard and the Asic Boards and cables are ok.
Looks like its time to swap cables between your 'good' unit and the 'bad' one.  Maybe its just a single faulty ribbon cable between the controller and the hashing boards.

Cheers

ribbon cables are ok. tried this before.
