Antminer S9 one board is not hashing

[eotrix]

I can see all 3 boards with 63 asics in interface but one of them does not hash. I also wanna share that info, I measured all the chips resistance values and one of them has x2 as much resistance value then rest 62. So what might be the issue for this hashboard that causes it not to hash.
Any opinion is highly appreciated. Im trying to fix my Miners

Much better if you can post the kernel logs here or in pastebin.com.

You can find the kernel logs under system>Kernel logs then copy them all then paste it here.

We don't know if it is a hardware issue or related to the software issue so start first in software before you touch any parts on the hashboard.

I will do it first thing tomorrow, thanks.

This can be a power supply issue, the PCI-E cable/s connected to that particular hash board might be bad, did you try swapping the PCI-E cables from a working hash board?

Which test points are you using to measure the impedance, and what is the chip's position? Generally the outer rows of chips do have higher impedance, but it shouldn't be double..
