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!
Cheers
Did all these and no change!
Thanks s lot for your attention
