Antminer S9 one hashboard stop appearing in STATUS

[ikon31]

Hi everyone.

i am having trouble with my S9 12.5TH/s.

I bought the miner on May 2017 and put it mining in a server room with no dust and room temperature from 19 to 23 Celsius max.

The miner had chip temps around 69min-82max and fans around 2000min-3200max rpms.

I use the APW3 of Bitmain`s PSU.

Yesterday i noticed that one of the hashboards does not appear in the STATUS window(NO XXXXXXXX`s NO --------------`s just not appearing.it only shows 2 blades).

The miner hashes at 2/3 of the total power and consumes the 2/3 of the maximum voltage.

I also touched with my finger the top end of the circuit boards of the 3 blades and one of them is DEAD cold. The other 2 are just a liiiiiiitle bit worm(i believe this means no current passes through the one board?).

Also there is a red light in every hashboard and on the COLD hashboard is NOT light.

Is there a way to fix it or do i need to sent it to bitmain?

I mean if flashing new firmware, change cables, hard reset(if there is such a thing), check control board etc is going to help.

Please any tips are welcome.

Please note that i don`t have other antminer in hand. it is the only one.

Thank you in advance and sorry for my English as they are not my primary language.


UPDATE:

1) I left onboard only the one blade that does not had the red light on and connected 3 6pin power cables from the other 2 blades which they were working and switched ON. NOTHING happened. NO hashing.

2) I used different 18pin signal cable from the controller in case that was the problem and switched it ON. Still NO hashing.

I believe updating the new firmware wont do nothing?

Plz help.

Thank you

Time for a warranty repair with Bitmain and if there is no warranty time left then it's time for a repair with Bitmainwarranty (different company than Bitmain).

See their repair guide for more https://shop.bitmain.com/workOrderGuide.htm

You must carefully follow their instructions in the repair guide for the shipment and everything

...
b. For the miner, if your miner is:
S9: Shipped before October 1, 2016, please ship the defective part
      Shipped after October 1, 2016, please ship the whole machine

[fanatic26]

A firmware flash only affects the controller. You have a bad hash board. These are string design and it only takes one failure point to kill an entire board. If you purchased it new from bitmain in May you are still under warranty. You can put a ticket in and ship it to the los angeles depot for repair.

New UPDATE 26/9/2017

I tried and flashed the new bitmain firmware and all of a sudden the third hashboard appeard in the miners status and for a couple of hours it worked perfect.

The hashrate came  back to 12.5ths.

BUT two hours later the hashboard desappeared again

Does anyone know what is happening?

Plz help.

[NotFuzzyWarm]

As said before - you have a hash board that is failing/has failed. It is not uncommon for a bad board to run for a bit and then drop out.

[ikon31]

Thanks For The fast replay.

I will try to repair it although i dont know if it is worth doing so or just leave it with the two boards hashing.


Thanks once again people.

Hi,  i have this same problem with s9 13.5  
a hashboard disappeared from the panel, now only working with two hashboards.
I have already done firmware update several times, already tested the hashboard in other connectors and the cable of the controller card also and nothing to work,
I noticed that when the equipment is turned on, the red light on the hashboard lights, but then it goes out and does not come back on again

If anyone has any solutions thank you for the attention. Thank you very much, good luck to all.

look img panel.

***
After 1 day off the machine and restart again and the hashboard show in panel as the image shows, but the temperature is marking 0.

Any solution please
All thanks

I have the same exact problem....  , I Even swapped the cables from the psu to the hashboards around just to rule out the cables, and for a brief moment the hash board in middle's(The one not working) light  alone was on, then back to the two outer hash boards working with the light of each one and the one in the middle off, I have mined for 48 hours total the first 5 of whick I was mining at an avg 14TH and after in an avg of 8.5TH. Of course that bitmain will take an eternity to answer... so I was wondering if any computer technician could see anything like a loose cable and just attach it back, or is the miner such a weird device that a normal computer person wouldt understand. I am out of warranty and prefer to mine at 2/3 capacity than not to mine at all.

Thanks Bros

The hashing board is dead, and there really arent any parts serviceable by someone not adept at board level repair.

The only solution is to send your board out for repair. It is normal to have blades randomly die on older s9s.

[ccs]

Sad to hear that... Specially since I was not able to install the machine until last week because some personal issues. The machine is out of warranty but never used except for these 48 hours I mentioned

[shemoura]

Hi all,

I got Bitman response:

Please try these three methods to reset your machine: https://enforum.bitmain.com/bbs/topics/3957
Then load the firmware from this page: https://shop.bitmain.com/support.htm?pid=00720161126080548570Q2tDBXAH065D
Select the file in the last row of the table.
Run the miner for 20 minutes after loading the firmware.

If the issue is not resolved please carefully read and follow these instructions to create a Repair ticket and ship the machine back to us: https://shop.bitmain.com/workOrderGuide.htm

Please let us know if you have additional questions or concerns.
 
I made all the attempts and no success the middle hashboard still does not back work.

complicated to have to send the complete machine to repair only the board that this problem., they should make change of hashboard with problem even if it has some cost.

and the time of receiving the machine back and  absurd custom tax rates depending on the country that will be charged.

I'm trying to contact some technician in China to do repair and send only the hashboard with problem. 

[btcurrencies]

For all of you with this problem....
i found the solution for the third chain missing!

its only due to the bitmain PSU.

change it to one 1600W not bitmain and your issue will be solved!

this worked for 4 s9 ! not only one.. just change your bitmain PSU

[beebo]

Hi I also unpacked a brand new antminer s9 yesterday, 1 hashboard not showing.  Checked all cables and reloaded firmware, still not showing.  Using bitmains psu.

@btcurrencies.  I have 1 1000watt psu available. Can I try powering just the faulty hashboard with the 1000watt psu or will I need to purchase a 1600 watt.

Any suggestions to which 1600 watt power supply to purchase.

Thankyou in advance.

[mstubs]

Im having the same problem with TWO 13.5TH S9s I just got today. I tried 2 different Bitmain PSUs and both S9s sometimes show one board, sometimes 2, and for a few hours before a restart all 3. Can you confirm another PSU will fixed this?

Also I have an L3 that mines just fine with both PSUs. What gives???

you need a 1600w not not the bitmain one.
you will see that by changing the bitmain one to a standard one will fix the card hashing..

[lightfoot]

That's interesting. Any chance one of you who did this and has it working can go back to the old supply and check the voltages at the PCIe plugs on each board? I'm wondering if there is a sag somewhere, maybe the problem is one of the Bitmain supply rails is going bad and it shows up as a dead card..... (assuming their PS has three rails this could happen)

[Minestrone]

Set up my new s9 yesterday with three 750w psu`s , one of the psu`s also powers the control board. Everything was running fine until I turned off the machine to tidy up some cables. When I powered it back up I noticed the middle hashing board was not working and the psu powering this board had stopped. I swapped around the psu`s and whichever psu is connected to the middle board it won`t run. Tried a reset to no effect. Its almost as if there`s a short on that board and the psu that is connected to it is shutting down to protect itself. Anyone else had this problem? I prefer to fix it myself rather than returning it to Bitmain.

[lightfoot]

If you want to fix it you probably have to pull the FETs on the board, at least the high side ones. This will require hot air tools, good flux, and a good pre-heater. I have all of these, if you want me to look at it drop me a PM and I'll send you my address.

Lightfoot.

[Minestrone]

Thanks for the offer, I think your in the U.S. so as i`m in the U.K. i`ll wait till I get a reply from Bitmain. I`ve asked them to replace just the board so I don`t have to return the whole unit. For some reason they offer this service for other miners but not the S9. If they won`t agree to that then I guess its going to be an attempt at repair. I have a heat gun and experience with soldering/desoldering components, assuming I can source those particular components here. I sill don`t get why  these boards fail so regularly, (I had the same problem with an S7)

[lightfoot]

My one recommendation is get a board preheater. Really, it makes air tool removal easy, clean, and reliable. A hundred buck Aoyue quartz preheater is like God in a little box.

That and a Hakko battery powered part picker will make you a champ.
