Antminer s19 pro hashboard seems to be faulty

[shaykal]

Hello everyone,

I purchased the Antminer s19 pro last week and it arrived 2 days ago.
when I start it up, it looks like 1 of the hash boards doesn't work well.
These are the lines from the log of the miner that are related to this issue:

2021-07-09 06:56:47 Chain[0]: find 114 asic, times 0
2021-07-09 06:56:54 Chain[1]: find 109 asic, times 0
2021-07-09 06:57:03 Chain[1]: find 109 asic, times 1
2021-07-09 06:57:11 Chain[1]: find 109 asic, times 2
2021-07-09 06:57:12 Chain 1 only find 109 asic, will power off hash board 1
2021-07-09 06:57:20 Chain[2]: find 114 asic, times 0

In addition, I see that only 2 hash boards out of the 3, are mining.

The mining value is 72 TH/s where it should be 110 TH/s

Please also see screenshots from the Miner's Dashboard:

 Return it for warranty service.  The chips are not soldered properly.

Try some basic things first before you send it back for a service warranty.

Try to reset it to factory default by holding the reset/IPreport button for 15 seconds and try to run it again.

If not flash the firmware with the latest version available from Bitmain here https://service.bitmain.com/support/download?product=Antminer%20S19%20Pro

If nothing works then your last hope is to send back to Bitmain.

I tried in 2 different ways, the one you suggested, and there is also a possibility to do a factory reset via the web page of the miner.
Anyway it didn't change the results. the second hashboard is still offline.

If not flash the firmware with the latest version available from Bitmain here https://service.bitmain.com/support/download?product=Antminer%20S19%20Pro

I updated the firmware, but it looks like I already had a later version.
The firmware version that came installed in the miner was from April 10th 2021, and now after I installed the firmware from bitminer's site, the version is Dec 11th 2020..
Anyway the second hashboard is still offline...

Code:

2021-07-09 06:57:03 Chain[1]: find 109 asic, times 1

The signal is interrupted at chip 109, so chances are chip number 110 is bad, it's either toasted or lost contact to the hash board, these asic chips are connected in series, the miner firmware is designed in a way that if it does not see all chips, it simply shut down that hash board.

You have two options:

1- Follow Phill advice and return it for warranty ( they will probably ask you to ship the whole miner)

2- If you do the math and think that wasting a few weeks/months of not mining isn't something you want to do, mine along with 2 hash boards, take out the dead board and send it for repair ( at your expense), of course, all of this depends on your location and budget.

On a side but related point, if you could convince Bitmain to send only the dead hash board and not the whole miner, it would be your best option.

I have an update:

I opened a ticket in bitmain site, and they recommended to flash the SD card.
so I flashed the SD card to recover the control board. Since then, not only that the second hashboard is still offline, now the other 2 hashboards that used to work, are in abnormal state and don't work at all...

would someone know what to do regarding this issue?

In addition to that, I opened the lid, and it looked like all the cables and wires were tight. I did try to switch the wires, and now boards 2 and 3 are online, and board 1 is offline.
so I guess that's good news.... right? I hope the the problem is with the wires (or PSU) but not the hashboards.
But anyway, the 2 boards that are online are in abnormal state, so the miner isn't hashing ....

Does anybody know how to get these type of wires?

I'd appreciate it if someone could tell me additional things I could try.

Email them and say now it is fully bricked.

You want a replacement.
