But before it used to drop another board after been mining for a wihle. So there migth be another bad soldered Heat sink missbehaving when heating up

Yes, that is exactly the cause, one or more heatsink are not glued perfectly, sometimes they will contact and read and sometimes they don't, I have a few boards that behave this way, just mine with it until it longer functions, the bad heatsink will eventually fall off or at least becomes so loose that you can identify it with your bare eyes/hands.

I will try to contact their support to see if I can get in contact with someone from Poland.

go to this page > https://www.zeusbtc.com/Repair.asp, scroll down and you will see a list of some cities/countries, looks like you have to keep your contact information and they should contact you.

The site also mentions

Attention: The miner repair points shown on the map below are independent individuals. This site only offers a free display. Please contact the maintenance point for specific matters. If there is any dispute, please resolve it by negotiation. Any consequences will not be related to this site.

So it doesn't seem like they are a branch of Zuesbtc, but I can only assume that Zeusbtc must have done at least a basic check on these guys to confirm their integrity, some of them might have got some training in China from Zeusbtc, I tend to think that they can be trusted, but I would still. deal with caution

I think Zeusbtc have a branch in Poland, not sure if it's just a workshop where they only repair your miners or they actually do sell stuff, it might be worth looking into it, perhaps you or mikxxy should get in touch with them, if you don't get an answer I'll reach out to someone from Zeusbtc.

I'd wager that it's only repair shop in Poland, as their website sells everything over WhatsApp orders and they seem to have their warehouse in China (Hong Kong?). If you have someone from Poland branch, feel free to give me his contact or ask him if they have any warehouses in Europe.

Otherwise, I will try to contact their support to see if I can get in contact with someone from Poland.

Status is now 1-T17 about to solder the poped heat sink, the other 2 cards seem to work ok! But before it used to drop another board after been mining for a wihle. So there migth be another bad soldered Heat sink missbehaving when heating up a bit, standing i the farm?. Been knocking around with a pen, I ordered a fixture, so we will see.
2-T17+ the original 'dead one', is now working fine, after it received' a working control board
3- T17+ (the control board donor) Seem to have 2 boards working ok, and the third one not startng due to problem with pic processor. i'll will try to change around hash board cables to isolate problem. The control board came from the 'dead' T17+, so i migth have some issues. It came up with a connection error last night, so i'll check if it remains.

Update: After identifying a bad ribbon cable the other T17+ also works fully, the connection issue was becuase of some instability caused by the faulty hashboard connection!

Sadly, as of 2020 I cannot seem to find any reliable resellers here in Europe for parts. I had to order anything I need from Bitmain when they had it in stock and from some resellers I found on random websites and in random telegram chats. Shipping anything was more expensive than the parts I was ordering. It was NOT worth it. Any broken hardware that I have right now will be RMA-ed as that is the best cost-effective move I can do right now. Others might know more or have better luck, but this is my experience.

For example, I have Innosilicon T2TZ with burnt PSU and fully operational hashboards (tested on other unit). Ordering new PSU would cost 110 USD and shipping for it would be 130 USD. While I bought the whole unit (used at that time) for 500 euro.

eFuse line seems to be normal thing during auto-tune and sometimes during reboot of miner. I've noticed on a lot of different WORKING units which were running Vnish firmware.

As for pool connection failed, I'd advise to try different network as yours might be blocking some ports like devfee pool ones and that would make the unit stop mining (I've experienced this first hand with my home network on thierry4wd's firmware, even though the unit works fine on the network which I use for miners only).

If that is not the case, then mikey's advice to check pool settings and asicboost should be the things to look at.

Take it easy, we all have lost many gears, the failure rate on these 17 series is much more than you can imagine, I would have been more than happy if I got 6 months of all my 17 series gears, so you are not in the worst situation one can be.

Recap:

1- I assume the T17 is done with and you are going to try and solder the heatsinks?
2- You have 2*T17+ , one is fine another one has a bad control board, when you try them on a working control board you get the errors you posted in the last post? is that the case or am I missing something?

If I am on the right track, you should know that mixing hash boards from different miners will cause many issues, so while you are trying to fix all this please keep track of the different hash boards and to which control board they belong.

Alrigth i see what mean.. i hava tendency to go down into the Rabbit holes when something from my point of view ocours, yes and things may get out of contex and thus causing confusion. So im sorry for any incoinvience caused.

i have no outher means to test of the bad card by any other means than trail and error. with the apprieciated help from you guys. All the equipment mentioned, has been running att smal miningpark for at least 6 mounths , and all the settings are also the origional against Poolin. So all the odd behavior described herein emmenate from known and reliable mining conditions. The Antminer T17+ is out of stock and those few contrilers that find their way to Ebay, are very expensive. //Mixy----------------------------------------------------------

So what could by wrong with this controller?

When a control board is bad, you would expect all kind of weird problems, and honestly, things now are becoming confusing and hard to follow Huh

, can you just not test the bad control board so we all can focus on the good one?

That is unfortunate, I don't know of any trusted suppliers there, but should you need one I think you should contact one of these guys (in no particular order)

There might be others, but those are off the top of my hand for a list of EU based miners that can be trusted.

Regarding the poped heat sink can it just be glued on and then reinforced by glueing the top of the heatsink to those in vicinity?

This line is very strange, I did text Marc (Asic.to) on telegram, let's see what he knows, it seems like a power-related issue, are you sure the PSU you using is APW9+ and the input voltage is 200-240v?

Also, it shows this

Pool connection FAILED. Check INTERNET, POOL URL or WORKER

Are you sure your pool settings are in place? is Asicboost is activated make sure the pool is AB compatible if this log comes from the bad control board and all this info can be misleading.

Yes im with you,. when i try run the bad controler in the second maschine it behaves exactly as in the previous setting, by not beeing able to detect correct asic valuse but in addition, now also giving error of not detecting any fans, even though the are spinning accordingly to pre setting of 30% (awesom FW), could it be affected by any virus in any of processors? A leds onboard are behaving as expected, boot sequenceas as it should, then it tries to initialize the hash bords iindefinitely. So what could by wrong with this controller?

Regarding the poped heat sink can it just be glued on and then reinforced by glueing the top of the heatsink to those in vicinity?

By joggling the controller back and forth, i started to catch on Awesom, detecting asic chains but the first one, also it warns if try to raise freq some steps above 500Mhz

whats confusing as said is the T17+ and none with different amount of chips on each board, 44 and 64?, should they need a designatet FW depending on asic count on each hash bord? Awesom issued two different FW's 1.00 and 2.0.3? Ill try the first one on the faulty card, may be it will run?

That is strange, I don't think the firmware knows the number of chips i.e it isn't hard coded into it, it probably gets the information from the hash board itself, the reasoning behind my point is that using the same control board and the same firmware you can run different hashboards, for an example if you take S17 hash boards and put them in your S17 pro they will work just fine despite having different asic count.

But with that being said you should reach out to Patrike and explain the issue to him.

Yes rigth, the T17 with a poped heatsink present it self at initial phase of power cycling, 000000 and then it wanish from the Gui, so i migth be alive, lets see what will happen as i glue i back then.

JES, problem identified! The culprit is the control board......but i think its easier to just get a replacement board?

That is good news, it's very unlikely for a control board to toast, which is also why it would make sense if you found some very cheap control board, bitmain store is out of stock, so you need to get it from elsewhere, are you located in the U.S?

Quote from: mikxxy on November 27, 2020, 05:01:12 AM

I open up another one, a T17 it had actually a heatsink off! there is some videos in Russian language, about fixing this, but i semm not to understand if the chip is replaced or resolderd? i should be burnt shortly after heatsink falling off, while in mining mode?

If the chip is bad then it needs replacement, but most of the time if the chip is toasted the heatsink won't fall, if the heatsink is off that hashboard is likely going to stop mining before the chip is burned, so usually, a heatsink that is off just needs resoldering.

Quote from: mikxxy on November 27, 2020, 05:01:12 AM

Isnt there a way to just "short" the bad chip out and thus restoring integrety of the chain?

None that I am aware off, but let's see what the other guys have to say although I doubt such a fix is possible.

JES, problem identified! The culprit is the control board, looks normal, there seems to be some problem in or out coming signals to the net,it does not identify itself on a IP scanner. changed inbetween the healthy one an d the bad one, so no problem with the hashboards. Awesom was inndicating 44 of 66, wich is wrong as there is only 44 chips on each board. Bitmain has produced several models of the T17+ this particular one has 58Th, so the Awesom FW got confused. Regardind the control board it may just be something with RJ45 connector, but i think its easier to just get a replacement board?

So you put the thermal solder on the chip? Do I need to put anything on the heat sink such as flux or something else?

This video shows a method of cleaning up and applying solder to attach the heat sinks: https://youtu.be/F6L9hCQ4OhY

A bit of tacky flux can help to get the solder to flow and adhere to the chip surface. Flux plus solder wick is used to clean up excess solder. This is the solder paste, flux, and solder wick I use and have had good results with:

Should be a separate power circuit for the boards.

There are indeed two different circuits and this is so confusing to most people, they see the LEDs turn on and they think it's a confirmation that the PSU is in perfect shape which sadly isn't really the case.

Quote

I have another, a T17 that lost one (occasionly one more), but controler detects the faulty board, some data as voltage is shown

If I understood you correctly, you have another working T17 PSU (APW9) that is powering a single hash board, and sometimes two, and we know you "most likely" have a dead PSU and 3 working hash boards, wouldn't it be wise to take the working PSU and instal it on the "potentially" working 3 hash boards?

Quote

ill disassemble the psu to check if theres any visual damage, dont know anything about testpoints or so, would appreciate any suggestions for where to search.

We milked this topic quite a bit, but long story short these PSUs were not really meant to be fixed, it's not that it's impossible to fix them, but once you open it you will get the point, to me, anything except for a simple fan change on those PSU isn't working looking into, and I doubt you will find many resources regarding the subject, so if you are not an expert in this field, chances are you should be looking for a PSU replacement.

It was indeed a button to press for takning the top cover off, never seen this one. I dissassembled the miner and all the hashboards look fine no lose heatsinks. im leaning towards psu, as it happend simutaniusly.I conclude that theres power to the boards and fans, but its not powering up hashboards. Should be a separate power circuit for the boards. I have another, a T17 that lost one (occasionly one more), but controler detects the faulty board, some data as voltage is shown, and also a asic count before powering it off

Watch this video on solder balls, 0 asic or when hash board only detects 44 chips or 22 chips and so on.

That is a great video, I did hit the like on it, I have a few things to add

1- When there is a short-circuit caused by anything whether it's excessive solder or a heatsink that dropped and shorting other chips, 99% of the time you will get 0 asic and not 44, 22, and the other weird combinations.

2- You talked about buying the black glue from China, it's indeed a good product and extremely cheap, but that product has to be stored in the fridge, it can't be at room temperature for more than 10 days, and with the pandemic and the slow worldwide shipping it could take more than 10 days so make sure you check with the courier or get another alternative from the local store.

3- The problems you talked about are very common in all 17 series with no exception, so it's probably worth mentioning.

Also, I would change the video title to " Chain[]: find 0 asic Antminer" as this will most likely be the most common keyword people would use.

Jup, all 3 spinn when powerd by both cords. Regarding PSU its way around, APW9 instead of the plus version, for testing. the miner stopped rigth after i powered back one of the cords due to the powercut, red led came upp instead of the green in end of power cycle, so that seems indicate a total sudden loss of function, rather then a progressive problem?.

icould try with a psu from a T17 40 Th would that be sufficient for the test of the faulty T17+ 58th?

NO, don't do that, the T17+ uses APW9+ while the T17 uses APW9 EMC, I am not the right person to ask when it comes to electricity but my guess is that the APW9+ could damage your T17.
