I love GPU repairs. Now Im hooked on this. Please keep doing more videos.
This is so needed in the mining community.
Awesome job. This amount of detail and information is near impossible to find. A huge resource to the Bitcoin mining community!
Voice recording after taking the video and getting a person to film for you made this a very great high-quality tutorial! Thanks
At last a straightforward and informative video on S17 troubleshooting- well done! There is so much disjointed and incomplete information out there- I believe if you do start a series on how to diagnose problems with these ASICS your subscriber count will explode...
Thanks Paul. Glad I could help.
Very good video i hope you keep uploading
Nice. I use clock instead of Bo to find locations of issues but good detail and glad to see info on that resistor. That was something I was unaware of. Got a board I need to check now for that resistor
This issue is so easy to diagnose and repair. I hope it helps you!
@@upgradeya4868 I usually put uv glue over the jumper wires to avoid shorts as well but that’s not really in a location that would have to have it
very helpful video a tutorial on a bord with 0 asics would be awesome
Amazing job! I hope you continue to produce more content on the S17!
Thank you!
Great i would like to see more of these videos! I have difficulties when all 48 chips are found but the temp sensors drops. Also can you make a video of all the parts on the s17 board and what they do? Or maybe make a separate video of all the different error in the log and how to solve them. Thanks!
Thanks Arthur! Yes, my next video will be an introduction to testing, covering all the circuits. After that I plan on discussing how to properly troubleshoot 0 ASICs
No need to change the BM1397 BM1397AG chip repeatedly - Refit Antminer S17/S17 Pro/S17+/T17/T17+/T17 heat sinks from NBTC!
Great videos. Would like to see more.
That’s awesome bro, perfect, keep going ahead
Great! Amazing knowledge sharing! Congratulations and thanks a lot for showing us.
Top vid. Sound is also prof. Quality! Thanks!
Glad you liked it!
Thank you brother, really appreciate the knowledge
Thanks great video
Really good need more of these....maybe ones on s9/s19 models..London,United Kingdom
Thank you. I'm only doing S17 and S17 pros right now. Maybe S19s down the road.
great! nice video ..very easy to follow...Thanks!!
The video is very interesting and impressive,I like is and watch it
Thank you for the video, very helpful.
I’m trying to get into repair of hashboards, and most interested in S17Pro’s.
Can you create a video, or point me in the direction where I can find info on the 5 different circuits” BO, RST,RI,CO, and CLK? Do all these circuits run through the Chips in the same manner as the BO circuit as you pointed out in this vid? How would you go about testing the other circuits? Same way, test the point at each chip compared to it’s heatsink, and check voltage level? What are the voltages for the other circuits?
I assume you changed the config file on the zeus ficture, to not do pattern testing? Otherwise it would try and hash, and create a lot of heat, correct?
I am about to post a video showing how to perform voltage tests using the Zeus Test Fixture. And yes, I did end up changing the config file to not continue with the pattern test. I wasn't aware that was an option when I made this video.
thank you for this education!
Glad it was helpful!
@@upgradeya4868 can we send units to you for repair? I would love a service which I could FaceTime/zoom/text/email you for help with board repairs.
Sorry, I only repair my own boards
I'm just getting in to S17 repairs. I am the kind of guy who likes to know "what's really going on" during a test. I'm a EE, so I feel more comfortable when I really KNOW what I'm looking at on a faiulre. I see everyone on UA-cam doing tricks like you show, shorting pins, measuring voltages, etc. But do you have a document that explains what the actual test is doing, such as 'sends pulses out CO' / 'configures each ASIC to loopback through RI' / 'change baud rate and try again' or whatever is really going on. I feel like that would really help me to understand the debugging of the various test failures. I've been on the Antmain website, and they seem very closed lip on technical details, unless I'm missing something... BTW, excellent video. The close up detail is very informative...
Hello Thomas, I know what you mean. No, I do not have any documentation that provides anything that detailed. That would be great if I did. I have spoken to some of the Bitmain instructors here in the US, and they have told me Bitmain is pretty hush hush with them as well.
This video is awesome! It’s my first time watching it, Brett who taught my class I attended for Bitmain training mentioned this video. Do you have any specs on the flux types you use and solder/solder paste you also use in repairs?
Using the stuff from Zeus that came with the starting equipment but I think the flux in the syringe too is a fantastic idea.
Thanks! Yeah Brett and I go back a few years. In case you are still interested, I just updated the video details to include links to a number of products I personally use and recommend.
very good in details!!!!! tanks
perfect. do not stop
Hello it's possible to have online training for my technician obviously whit payment thanks
great detailed video. do you see common issues with the s17+?
Thank you. Sorry, I've only worked on S17s and S17 Pros.
Can you recommend a online course or will you create a video course on how to run diagnostic, repair, and test.
I am about to post a video showing how to perform voltage tests using the Zeus Test Fixture.
@@upgradeya4868 thanks I will be watching it..
Awesome video. Do you have any on DR5 hashboards?
Thanks Richard. Sorry, S17s only.
There is absolutely no need to mess with soldering a replacement link. Conductive silver paint is perfect for the job, and you can even solder onto it once it cures, should you need to. Some masking tape, a steady hand and the job is done. Another note: you disconnect your +VE side last, not your -VE. Reason being is that your ground planes are much larger, and the likelihood of a short is much higher with a grounded board - much like a car's battery and routing arrangement.
Great suggestion about the conductive paint. Assuming one has that on hand, that would be a much easier method and wouldn't necessarily require the microscope. I understand your concern regarding the power connections, however I don't feel that is much of a concern here. In the case of the car battery, you're concerned with an accidental short, immediately releasing all the stored potential energy of the battery by means of explosion since there are no protective devices. Regardless, people do need to exercise caution when working with potentially live equipment, also taking into account that there are a ton of capacitors storing energy. Thank you for your comment.
Nice video...so if u dont get 48 chips ...u go after BO first not the other signals? If so why?
Not necessarily. Initially, I verify all the signals. In this particular case the BO signal was the only one that was bad. An important thing to note in this video is that it is not always the chip that is bad and you need to inspect the surrounding components.
Is that a raspberry pi device cna you link that please or is it custom, q tips is great but organic cotton is where it is at
No, it's the universal test fixture from Zeus BTC. I added the link in the video description. I'll have to give the organic cotton a try. Thanks for the recommendation.
Are the heatsinks of the s17 very easy to loosen?
If you are referring to them falling off on their own...No, they are pretty solid.
If you are referring to them being removed intentionally...Yes, assuming you have the right tools. Using a hot air gun, apply 450C heat directly to the heat sink. After about 10 seconds it should easily separate from the chip.
@@upgradeya4868 Thank you for your reply! I understand😄
@@fengyshan2097 They're extremely easy to fall off on long distance shipping though beware too many damaged rigs when ordering from abroad
Keep going!)
please help me s17+. unequal voltage ranges. test is still enough number of chips . The signal pins are still there. I'm stuck
What power supply is needed to repair an antminer s17 pro 76t card?Ampere?
Sorry, I only use the stock APW9 power supply for testing.
s17 pro how do you repair it if it says that only 47 asic found? thanks for video
Remove the heat sink on 48 and visually inspect. Hopefully it's just a solder ball, but you'll likely have to reflow or replace the chip.
Do you plan on doing any t17 tutorials?
Hey Deeg. Sorry, at the moment I am only working on S17s and S17 Pros.
Thanks
My pleasure
Hello, show me how to repair a board with a temperature sensor problem (Error_Temp_Lost). Thank you for the lesson.
Fortunately, I haven't had to troubleshoot any temperature sensor problems. The only thing I've experienced related to temperature sensor errors is if when I tried running a rig with a single hashboard installed. The unit does not like it.
try watching some macbook repair videos on how to deal with temp sense faults
I seen on another channel your involved with immersion mining, with the S17 pro's in particular I was wondering are they standing up better deployed in immersion? I'm buying used ones in 50 lots from china with the idea of fixing them on arrival and then throwing them in tanks. Glutton for punishment I guess! Cheap HR if you have a team to solder them back together!
Life in immersion far exceeds air. The concern I have for you is the quality of the used rigs you are getting. In my experience, there is a high probability you will have issues with some boards, and it is going to be a pain if you have to work on them after being in the oil. I suggest running them in air first until you find them to be reliable.
Where to buy this board sir
Sorry, I don't sell refurbished boards. I only repair for personal use.
Hello, My S17PRO machine cuts mining every 6 hours. I need to continue rebooting to make the machine mining again. After I remove 1 hashboard, the machine mining fine with 2 hashboards 24/7. What should I do?
When it stops are you still able to connect to it? or do you have to have to cycle power?
@@upgradeya4868 yes, I can connect to machine via IP address normal but machine not mining not show red or green light when I reboot the machine mining again but after 5 day keep reboot this the machine stop mining. Then I unplug wait couple day. The machine mining again and repeating reboot for mining work like this.
Hmm...if it was losing connectivity but maintaining power, it is likely the control board. Since that is not the case I would have to look at the kernel log. A single hot chip might also be taking the whole thing down as well.
@@upgradeya4868 Thank you very much. I did change control board still have same problem.
I quoted some kernel log.

Hello, I have several damaged T17, I managed to recover some by changing asic and temperature sensors, but due to an oversight on my part, there was a screw in the rods that feed the current cards, after that it throws me this error.

What could be happening? I have measured the parameters and all are correct
Wish I could help but I am not familiar with that error.
after scratching off the corrosion you recognize that there is a chinese high quality pcb underneath
I don't deny the quality of the boards. These boards are packed with components and they are put through a lot. As with any electronic component it is only a matter of time before environmental elements cause failure.
Great video! Keep it up
Would love to chat sometime
