Do you know if I can download the old software from Bitmain?

Do you mean firmware?

You can download the old firmware from Bitmain website from here https://service.bitmain.com/support/download?product=Antminer%20S9

Are you still having an issue with one hashboard?

Can you post the whole Kernel logs here so that we can analyze your miner's issue.

You can find the kernel logs under system>kernel log> then copy them all and paste it to pastebin.com and put the link here or paste it here as a code.
Don't forget to put the Hashboard chain(7) then run for 15 minutes then start copying the kernel logs and post it here so that we can check if the chain (7) has PIC fw issue.

Thanks just been looking on https://braiins-os.org. It all looks a bit complicated.

Ok great news, your miner is working now , seems like i guessed it right ( surprisingly Grin

) , despite there is no reason " or non that i know about" on why would a missing asic on a single board will stop the miner from mining, still it is a fact.

so what do we know now ?

1- the control board is ok
2- fans are good
3- psu is probably good ( there is a chance that it can run 2 boards but not 3 - but this is very unlikely)

now the only way for you to get that other board to work would be using a different firmware, you might get lucky and find a firmware that will still force that board to run despite the missing Asic/s, for a starter if you are not using 2019 then simply try old firmware such as the 2017 versions , try every firmware bitmain has except for the 2019 version.

if all fails, or if you are already using 2019 firmware , then i would follow @Artemis3's suggestion and try Braiins OS, in fact you have a better "hope" with it than with all bitmain firmware's combined, but for the sake of simplicity it's always wise to try the "easy" fix first.

Thanks everyone for the advice.

I have had to pinch a fan from it for another miner. When you say chain 7 do you mean the J7? Would this mean the middle hash board is faulty?

Ok I have just tried disconnecting J7 with using a fan from an A3

These are the results

Do try booting with Braiins OS, you can simply put an sd card and move jumper jp4 to boot from it. Braiins OS allows fixed frequency settings among other goodies. Take our the sd card and move the jumper back and its like nothing ever happened.

Far better than messing with Bitmain firmware, especially avoid 2019 versions.

What firmware version are you running? It's unusual for an autotune miner to have that ideal rate. I would recommend trying the May 2019 firmware (or Dec 2018, if you are uneasy about no longer having SSH access to the miner), and see if that helps.

You need to post the complete Kernel log.

anyhow, the middle board/chain is missing 1 asic, shouldn't be a problem but I have personally seen a whole gear fail to start mining due a few asics missing from a single board. so here is a list of trouble shooting process you need to go through.

1- disconnect chain 7 , power the miner on and wait for 10-15 mins see if this solves the problem ( very likely )

2- flash a different firmware version, roll back to old firmware 2017 if possible fixed frequency.

3-perform a hardware reset using the IP report method, while miner is powered-off , hold the IP report button, power on , don't let go of the IP report button , release after 10 seconds.

This issue can also very possibly be related to PSU so if all the above fails i would test with a working PSU.
