Not sure if you are still looking for a store for the S17 miner? At present, the Antminer 17 series miners are prone to the cooling fins falling off during transportation. So, if you want to buy S17, you can choose to buy S17 miner with modified heatsink. Or go for the S19, which seems more benefit. I saw used Antminer S17 for sale at zeusbtc: https://www.zeusbtc.com/Used-ASIC-Miner/Used-Miner-Details.asp?ID=1249

What I'm trying to tell you is that the most commonly damaged parts are different for each different miner. The good news is that recently the zeusbtc Youtube channel released an introductory video for "Easily damaged parts of ASIC miner", which I think will solve your problem.
Here is the video channel for wearing parts: https://youtube.com/playlist?list=PLg1kmGkrRa7XRmF02Qln3FpYYXXElgOc7

Hi, I checked your log. BOOTBY[0x11.00000000] is displayed, which means that there is restart caused by no hash rate within 5 minutes.

Wenn Ihnen ICs und Ersatzteile für die Reparatur fehlen, wenden Sie sich doch an zeusbtc.com. Dieser Lieferant hat viele Reparaturwerkzeuge und Zubehör für ASIC-Miner. Und kann in die ganze Welt verschickt werden.

Thanks for sharing. If this is true, I'm really sorry to hear the news. After reading your instructions, I searched for news about ComputeNorth. One of the articles said that nobody at computenorth.com has come up with proof that the platform offers fast payments for cloud mining contracts. Probably a fake cloud mining service provider, so we'd better stay away from this store.

I think maybe, but probably not that fast. The latest ASIC miners on the market currently use 5nm chips, and I'm looking forward to applying 3nm process technology to ASICs. According to reports, compared with the 5nm process, the first-generation 3nm process can reduce power consumption by 45%, improve performance by 23%, and reduce chip area by 16%; while the second-generation 3nm process reduces power consumption by 50% and improves performance by 30%. %, the chip area is reduced by 35%.

Are the logs of the other 2 S19 the same? According to the log of this S19, I think it may be a problem with the PIC chip. The log indicates that no data can be read from the board. Or check to see if there is a short circuit.

According to statistics, Bitcoin and Bitcoin Cash currently consume about 70 terawatt-hours per year (1 terawatt-hour = 1 billion kilowatt-hours). This means that the Bitcoin network requires more electricity than the whole of Switzerland and the Czech Republic consumes. Russia’s central bank has been a hardliner in discussions about the future of cryptocurrencies in Russia, proposing a blanket ban on most related activities, including mining operations, earlier this year. Recently, however, the Central Bank of Russia (CBR) said it would agree to legalize cryptocurrency mining, provided that the output mined by miners in Russia can only be converted into fiat currency outside Russia.

مصفوفة البوابات القابلة للبرمجة الميدانية ، هناك فهم أكثر شيوعًا هو أن FPGA تقوم بتغليف عدد كبير من الأجهزة المنطقية ، مثل AND gates ، و NOT gates ، و OR gates ، والمحددات ، في مربع. كيفية توصيل العناصر المنطقية في المربع يتم تحديدها جميعًا بواسطة المستخدم الذي يقرر ، ويكتب برامج مختلفة وفقًا للاحتياجات ، ويمكن لـ FPGA تحقيق أي وظيفة. تمامًا مثل ألعاب Lego. تتميز FPGA بالمرونة العالية ، لذا فهي لا تدعم خوارزمية Bitcoin SHA256 فحسب ، بل تدعم أيضًا خوارزمية Scrypt التي تتميز بها ماكينات تعدين GPU ، ولكن أداء طاقة الحوسبة ليس مهيمنًا.

If your chip surface is clean and free of dents, you can choose to continue using the bad chip. But you're better off cleaning bad chips, which will need to be re-tinned using board wash water and aluminum alloy flux. Remember to wear a mask during the operation. However, I would recommend you replace the chip with a new one, because most of the bad chips can't operate stably and will have poor heat dissipation or conduction.

I was wondering if you tried replacing the control board? The temperature sensing circuit of the Antminer 17 series hash board is in the form of I2C serial bus, which is powered by the control board. Therefore, if the control board fails, it will not be able to supply power to the temperature sensor, and the temperature sensor parameters will not be collected.

I have 1066, but currently, it's not working. If possible, I hope Avalon can give some related maintenance manuals, there are too few maintenances related to Avalon on the market. I want to buy a 1246 miner, but don't have any schematic at the moment, and once it stops working, how to repair it?

Hello, the log shows that the chip is abnormal. Please replug the cable connecting the hash board and the control board, or swap the cable of the faulty hash board with the cable of the non-faulty board, upgrade the latest firmware, and see if it works properly. If it still doesn't work, it needs to be repaired, to check whether the voltage between the voltage domains is abnormal and whether the impedance value of the chip is abnormal, if the impedance value is abnormal, the chip may be burned.

I'm not sure if I get what you mean. If you're trying to mix the 2 types of hash boards, I think something could go wrong. After all, the ASICs they use are not the same. If there is no suitable repair center in your country, then you can check these repair manuals for troubleshooting:
How to Repair Antminer T17 Hash Board?
How to Repair Antminer S17e Hash Board?

I don't recommend you buy a faulty or scrapped hash board to get the BM1397AG chip. Because most chips have been oxidized or damaged during use. Even if there are good chips, you need to clean and tin these chips before use, and some chips will still have unstable hash rate even after tin plating. After all these complicated and time-consuming operations, you're not necessarily going to get a good working chip. If the connection to the heat sink is poor, it will lead to poor heat dissipation and may even burn your entire hash board.

I believe BTC winter will be over soon. Bitcoin has so many loyal fans, and more and more people and countries are starting to look at the future of Bitcoin. The presence of such billboards will help more people recognize and start to understand Bitcoin.

Whatsminer M1 Hash Board Repair Guide

1. Introduction to the principle of hash board:
M1 is composed of 22 voltage domains in series, each voltage domain has 3 SMIT1700 chips in parallel, and there are 66 SMIT1700 chips on the whole board. Each voltage domain has an independent LDO to provide IO voltage and PLL voltage, the D05 version has an independent 24M clock circuit for each voltage domain, D06 is the clock provided by the previous chip, and each chip has an independent small heat sink on the front and back device, the front small heat sink (A) and the chip are fixed by a black glue with good thermosetting adhesive. The small heat sink (B) on the back is soldered to the chip's ground, so the heat sink B is charged and has voltage to the ground. Particular attention should be paid during maintenance to prevent short circuits.
https://www.zeusbtc.com/share/Whatsminer-m1-hash-board-repair-guide/m1-hash-board-signal-flow.jpg

As shown in the figure above, there are 5 signals in the communication between chips. The arrow shows the signal flow. Each signal has test points on the front and back sides. They are arranged from left to right: CLK, RXDI, TXDO, CTS, RST or RST, CTS, TXDO, RXDI, CLK; the CLK test point is close to the crystal oscillator side.

3. Schematic diagram in a single voltage domain:
https://www.zeusbtc.com/share/Whatsminer-m1-hash-board-repair-guide/schematic-diagram-in-a-single-voltage-domain.jpg

1) The clock circuit composed of crystal oscillator Y1 and chip U1 generates a clock signal and outputs it to the next chip through CLKO. V1.0 PCB D05 version has a crystal for each voltage domain; D06 is the last chip of each layer of voltage domain and is output to the next layer of voltage domain through level conversion;
2) U67 is an LDO, and the input voltage of the LDO comes from the fourth layer voltage domain behind the layer voltage domain, outputs 1.8V to the IO power supply, and generates a PLL voltage of about 0.9V through the resistance divider;
3) Diodes and pull-up and pull-down resistors form a level conversion circuit, which connects signals across different voltage domains.

4. Schematic diagram of the boost circuit:
The 12V is boosted to 16V through the TPS6116 to provide the input voltage for the LDO in the last 6 voltage domain.

Observation of appearance: Observe whether there is displacement, deformation, and burning of small heat sinks? If there is, it must be dealt with first; observe whether there is burnout of the device, and clean up the burnt device first.
Measure impedance: Use the resistance gear of a Fluke 17B+ multimeter to measure whether there is a short circuit in the voltage domain of each layer. If the resistance value is below 2R or above 7R, it can be judged that there is abnormal chip resistance in the voltage domain of this layer. It shows parts in the abnormal voltage domain with open circuit and short circuit phenomena. The most likely cause is the general chip. But there are three chips in each voltage domain, and often only one of them fails when it fails. The method to find out the problem chip can be detected and compared to find the abnormal point through the test point-to-ground impedance of each chip. If you encounter a short circuit, you can remove the heat sink on the chip with the same voltage, then observe whether the chip pins are connected to tin. If there is no short-circuit point by appearance, you can find the short-circuit point according to the resistance or current cutoff method.

Measuring voltage: Use Fluke 17B+ multimeter to measure whether the voltage of each layer is between 0.5~0.7V.
Use the test program to read the chip ID; as shown in the figure below, the communication cannot be performed; it can be judged that the TXDI PIN of pin 21 of the chip is not pulled high; you can measure the test point TXDO through a multimeter, and quickly locate a particular place where TXDO is not pulled up using half-folding search, and analyze whether the connected chip is damaged.
https://www.zeusbtc.com/share/Whatsminer-m1-hash-board-repair-guide/test-program-reads-the-chip-id-interface.jpg

Use the test program to read the chip ID. If it is found that there are only three chips or less and the chip ID cannot be read, use an oscilloscope to check whether each chip has a clock input. Because there is no clock input, the test program will skip the chip. If it is found that part of the chip ID is read, it will be terminated. In addition to checking the clock, you must use an oscilloscope to check whether there are waveforms in TXDO and RXDI to determine whether the signal is normal and locate the position where there is no waveform. Check the level conversion circuit composed of diodes and pull-up resistors if it is a position across the voltage domain. If there is no problem, the adjacent chips at this position may be poorly soldered or damaged.
You can use the test program to run 10,000 times for waveform measurement.

The Antminer T17 hash board has a total of 4 temperature sensing ICs, the model number is TMP451. They are located in the third row from left to right, and the third row from right to left, one on top and one on bottom. The top 2 are next to the ASIC chip, so you may need to remove the heatsink to see them. The bottom 2 are located at U88 and U89, these two are not covered, so you can easily find them. Except for the S17 and T17, the temperature sensing ICs of the 17 series are arranged in this way.

Black glue does work well for sticking heat sinks to chips and requires refrigeration. But this thermoset adhesive is usually used for S9 and L3+, black glue is usually not used for Antminer 17 series hash board. The heat sink of 17 series is usually soldered on the tin plating on the surface of the chip, so long-term high temperature can easily cause oxidation and the heat sink will fall off. This is the most common failure of the 17 series. At present, if there are too many falling heat sinks, the best way to solve this problem is to refit upgrade heat sink.
