Can you first answer my question / tip?

Try asking Bitmain or www.zeusbtc.com ?

I have not repaired them at component level.

Does those hash boards work ok with the other PMU board?
Sounds like there could be a damage in the PMU board?

If so, you would need a replacement PMU board, like from Canaan or www.zeusbtc.com store.

@Fuzzy, trying my best but I'm not always here

Go see here https://bitcointalk.org/index.php?topic=5297994.0

Mikeywith has already created a pinned thread about this repair shop -topic.

ESD damage then, maybe?

Did you work with ESD precautions?

Bad cable connection?

Can you try to use another pool for test (like kano.is   maybe?) and try to do the pool setup from the beginning by following my guide? https://bitcointalk.org/index.php?topic=5164326

Which country are you in and what is the voltage? Is your power grid stable?

Is this only one miner down and others are running ok?

I can not see anything specific in the log.
Even the ECHU error code is empty.

@chrysophylax
Dude, you need to chill, seriously.
I do not see any insult here.

See previous post and the url link posted by Pendrak,
for explanation.

I guess a shady illegal mining with free power (like it seems they did in Ukraine) is needed for PS4 mining to turn profit

Yeah you need a lot more than that to create trust and proof you're real.

@Phil

But according to Bitmain, APW3++ can do 1200W with 110V mains voltage.

I fully agree with throwing the transformer ideas to trash bin.

I guess it should not be too expensive to have an electrian wire a 220V  circuit.

Can you take one unit to another location, for a test,
and set it up from the scratch by following my guide?

https://bitcointalk.org/index.php?topic=5164326


In your log sample, it shows ECHU 130173.
ECHU stands for error code hashing unit.
130173 is a bit sum, 1 + 130172.

You can find description for error 1 and error 130172 here, see Table 4 ----> https://bitcointalk.org/index.php?topic=3224256

At this point there is not much else I know to say about your 1066..

Edit: One more thing came to my mind,
are you sure that your internet service provider hasn't started blocking mining?

I've heard of such blocking happening in some countries.

This is again one of those threads, in which I don't understand the most relevant question asked. Why open such messy threads?

Hölpölöpöpööpöööö question jiberrish joo ..

At 110V voltage, the max power output for APW3++ is 1200W. So you do not have enough power capacity for a S9.
You need to plug it in to a 220V circuit or buy an additional psu.

In the case of using another psu together with APW3++ you need to be very careful. Plug the APW3++ for two hash boards. Plug the other psu for one hash board and control board. Do not plug the psus to same hash board, if there is a direct connection between the psus, they will start to "fight" each other.

Power on the psu connected to the control board LAST.

Just a quick comment / suggestion.
Don't put too much pressure for Phil or others.
We all help each other voluntarily, free of charge, when we have time for it.
If you need help quicker, you need to buy it.

I don't remember seeing their thread here at Bitcointalk.
Could be that members here have little or no experience about their pool.

No, you can't configure with software the amount of ASIC chips that are in use.

Maybe Zeusbtc has a one?
