Could you make some without the Zeus Mining in the back ground so we can see more in detail what your doing on the chip fixtures.
Thank you

No need to change the BM1397 BM1397AG chip repeatedly - Refit Antminer S17/S17 Pro/S17+/T17/T17+/T17 heat sinks from NBTC!

There is almost no details on the diagnosis, this is just a repair video.

Hi, are you able to fix hash boards ? im looking to send few boards for check and repair

[ramonnavarro]

Friend, what do you recommend to mark the hash board? It is so that they are not confused with other people hash boards.

Hi, thanks for the video! I just purchased a second hand S9 but the chain[7] said he as 0 asics in the kernel log. Also the miner work only at 66%. I get refunded 33% of the price by the seller cause it say by his side the S9 worked perfectly. But now I'm looking for a solution to make it work. I already flash with the latest firmware version, change cable plug multiple time, restart 15 times the miner but nothing append. It always say that in the Kernel: Chain[J7] has 0 asic. Do you think your team can help me ? I'm located in Switzerland. Or maybe you have a simple idea on how to make it work! Thank you

[ahamilce]

Could you provide links to where to get the required tools? Mainly the tester and the Reball kit for hash boards

Здравствуйте, скажите пожалуйста, я занялся ремонтом хеш плат S9. Большая проблема при пайке чипа. Не могу понять по какой причине в местах ножек при припаивании у меня не образуются шарики ? Контактные ножки остаются плоскими и припой будто уходит под чип. Испробовал все возможные варианты но так и не понял как качественно посадить чип на место. Спасибо заранее за ответ.

Hi
I have a problem in repairing.
I had t17 hashboard that it showed just 16 chip.
In kernel log.
After change asic 16 and 17. Fault goes to 29.
After changing all of faults chips, every time showed me random number 9
after recheck 21
After some seconds 12
It show me 28 0 sign and 30 chips in status tab.
After restart all of number that i mentioned it change.
What is problem?

[mercucio]

I don't seem to be getting readable voltage on the contacts for the chips. Only the first one, "CLK"... this is for multiple boards... also: I only seem to get voltage when I reverse the contacts... Red on the board, black on the heat sync. I don't understand why I would be having this problem... :( I even tested known, working boards, as a sanity check...and even those boards are behaving that same way.

how to fix all unstable co voltages from ASIC 1 to 62 it only reaches 1.4 volts it should reach 1.7 or 1.8 volts how to make it normal please explain bro🙏 Greetings from Indonesia

Hey dude. do you have any full guide of the repairing Antminer?

[Daniel-tcvx]

@Kevin Chau: How much watt has the hot air gun? What is the diameter of heat gun nozzle?

[Riverwalk]

I don't understand. Did he replace the chip with a new one? or just repaired the old one?

[wsvitak]

What exactly is the black glue. I need to reinstall some heat sinks. I ordered 2 part thermal epoxy, but would prefer to use the proper glue.

[morgansemack]

wow this is some really advanced stuff. several of my heat sinks have come loose and I can't remove the old thermal pads to replace it with new tape. any suggestions? feels like I'm going to hurt the chips if I try to scrape too hard

[pouriaameli]

Hi
I had an interesting problem with the T1 model. Did you have this problem too?
All test points show that the hash board is healthy and the hash board gets hot, but it does not show any hash rate. Can you help me? I am repairing miners in Iran and I have a problem with the T1 model.

[abbaskarimi]

hi
my control board lose the cpu and i change cpu with new one. but not working because cpu luck on firmware when update with latest firmware.

thank you
