Thanks for replying, I checked the PDF version of this topic and couldn't troubleshoot it myself, that's why I am asking here for help.
"ECHU" is zero for all boards, "ECMM" is zero for all miners, "PVT_T"s are all within range, "CRC"s are all zero.
The fan is working at 10% (with rpm reading; and I can see and hear it); power is above 12v (multimeter and log reading), AUC is working and the controller detects the miner, so the MM should be alright. Also, controllers work with other miners so no problem there. PMU board reports ~12.3v input and ~4.1v output which is in line with other miners working correctly. So PMU should be fine. "PVT_T"s are also within reason. "MV" values are also similar.
However, I don't know what some values mean, for example, there are some >90% values for "ERATIO" and there is no description in the documentation. In the summary following is the difference between a working miner and a faulty miner for me:
"DH" > 90%
"TMax" is low comparing to a healthy miner due to the fact that there is no mining going on
"Fan" is at 1650 (10%) but this is expected, again, as there is no mining going on
"PLLX" for all healthy miners start with "0 0 0 0" but this isn't the case with faulty miners; but guessing this is the performance state of chips, this should be expected as the frequency is lower
"GHSmm" for all faulty miners are around 10TH, but this isn't true as I can clearly see power usage is too low for real 10TH mining.
"WU" is zero for faulty miners
"Freq" is around ~380 for faulty miners comparing to ~740 for healthy ones
"MW0", "MW1", "MW2" and "MW3" values are all zero in faulty miners
"PVT_V" values in a healthy miner are all around 4v, but this isn't the case for faulty ones, there are values ranging from 1.8v to 7.3v
"ERATIOX" values are between 2% to 6% for healthy miners, but faulty ones have a lot of 0% and some >90%
"C_XX_XX" values for faulty miners have a lot of 0 and low values in general (<60, <1000)
"GHSmmXX" lot of zeros and low values for faulty miners here comparing to healthy ones
The thing is, I have no Idea how to interpret these values and the troubleshooting thread or PDF don't provide an answer.
EDIT: I also just noticed that all three faulty miners have 9211901-faf6d80 MM version.

I would be looking to try a couple of things, as all 3 may not have the same issue, if any.
First I would just start working with the 3 miners giving you issues, so you don't have to unnecessarily start and stop the others.
My first thought on this is that maybe you have some bad/ 4 pin cables running to those miners, or they could be not seated properly. I had to once that despite appearing and feeling correct they needed to be reseated.
You can try swapping around cables with others that you know work for other miners.
Also just to note for further troubleshooting, are either of these miners on the same chain/auc line? If so the second one may have no problem if it is a cable issue.
What are you using to power your controller?
Edit: It's weird I took some time to go through everything and nothing jumps out at me as something obvious. I would still try them just on their own swapping some of the 4 pin cables around just to see if that helps. Definitely start a repair ticket with Canaan, and let them know what you have done so far.
In my experience they are really good at working through things with you, and from time to time depending on your comfort and knowledge can send parts out as opposed to asking for everything to be shipped back. Good luck and keep us up to date.

Ref the troubleshooting guide for A721/741/821/941 at the top of this section.
All the Avalons from at least 7 on up all work the same and have pretty substantial diagnostics built in to the API reports.

Hey
I just bought 12 Avalon 921 and out of these 12, I can't get 3 of them to work. Incidentally, I have 3 AUC3s and there is one faulty miner per each AUC3 in my initial setup; however, I checked one of the miners alone and the issue was still there, so controller and the AUC3s should be alright.
All AUC3s are green and sometimes I get a very short blink of red; however, all miners are blue even when I can feel they are cold and the fan is slow. This is also apparent with the CGMiner API Log. Controllers also detect all miners and there is no problem there. The only thing I noticed with faulty miners comparing to healthy ones is the fact that they have high "DH" value which I don't know what it really means considering the fact that all other error values are zero (MH, etc etc).
These devices make no hash what so ever (MW = 0 for all; DH > 99%). The fan is working, temp is alright and CGMiner shows ~10,000 GH activity (which is a lie considering the power consumption being like 0.5 to 1 amp). All PSUs are new and providing around ~12.3v.
Attached is the CGMiner API Log (With Debug Switch) while all 12 miners are connected. 3 faulty ones are easy to spot tho.
3 out of 12 is a big number for all new devices, and with all 4 boards not working and everything seems normal otherwise (MM, Internal Power Board) I think maybe I missed something; They can't all be really faulty; can they?
Sending them for warranty back probably going to cost me the same as buying 3 new miners.
