Hi, to all
Yesterday my Antminer D3 Chain #3 is disappeared!

Hi,
Can you control the power lines in chain 3 ?
Switch with power lines in chain 2 or 1.
If it works, it's a power supply problem.

I have switched the power lines but same problem, in kernel log I see this: https://s2.postimg.org/lmuv3cpix/zero_asic_chain.jpg
I have also switched flat cables, but same problem.
In the last I have insert the chain #3 flat cable in the last free slot (address #3) [chain #1 --> is chain 0, chain #2 --> is chain 1, chain #3 -->is chain 2] but same problem, in kernel log I see this: https://s2.postimg.org/k7taekypl/kernel_zero_asic_chain_3.jpg
Zero Asic for chain #3.
Why? And why I have same hashrate with only 2 working chains? I don't understand

I've had this same problem with 4 of my D3 miners now. I've done all of the troubleshooting, swapped power supplies with known good ones, moved hashboards, cables and even ran the miners with only the non-working hashboard connected which still showed in the global hashrate that it was hashing but the chain was showing 0 ASIC in the kernel log. I've shipped all 4 of those hashboards back to bitmain for repair.
