Antminer T17 hash board basics about the powering process
The structure of Antminer 17 series hash board is basically the same, 17 series mainly use APW9 PSU and APW9+ power supply. This course video mainly takes the T17 hash board as an example to introduce the repair tips of the powering process of the 17 series hash board. Remember, 17 series hash board has no voltage output if only the PSU is connected, and there will have a 16V-21V voltage output only when the control board is started. -
Antminer T17 hash board basics about the 5 signals
When the powering of the hash board is normal, the ASIC chip of the T17 hash board will have signal transmission. The T17 hash board has a total of 5 signals, CLK, CO, RI, BO and RST. It should be noted that if any one of the signals is abnormal, there will be no hash rate. This tutorial video will introduce how to troubleshoot the signal fault if the T17 hash board single-board test report is 0. -
Antminer T17 hash board basics about the temperature sensing circuit
The temperature sensing circuit of Antminer T17 hash board consists of ASIC chip and temperature sensor chip. The "TMP451" displayed on the barcode on the hash board indicates that the model of the temperature sensor chip used on the board is TMP451. Thermal sensors detect the temperature of the PCB and ASIC chips. If any of the 4 temperature sensor chips are not recognized, the hash board will not function properly. -
Antminer S17+ hash board repair teaching course
Antminer S17+ hash board has a total of 65 BM1397 chips, which are divided 13 voltage domains, each domain has 5 chips, and each group of domains gets a 1.5V domain supply. when the powering is normal, there will be signal transmission. If the S17+ hash board single-board test reports 0, we need to check whether the powering unit and the signals of the ASIC chip are abnormal. The S17+ hash board repair tutorial course begins. . . -
Antminer T17e hash board maintenance course
Antminer T17e hash board has the same structure as the S17+ hash board, but the number of chips is different, so the maintenance method is roughly the same. During the repair the T17e hash board, if a signal is abnormal, first check whether the domain powering and LDO 1.8V powering are normal. If the power supply is normal, it may be that a chip in a certain domain is in poor contact or faulty. Find the faulty chip and resolder it or replace it. -
Antminer S17 S17Pro hash board repair training course
The structure of the Antminer S17 hash board is the same as that of the S17 Pro hash board, so the repair ideas of these two hash boards are the same. This video will take S17 hash board repair as an example to explain in detail the powering process and signal transimission. It should be noted that the signal test points of these two hash boards are different from other hash boards. Please check the video tutorial for details. -
Antminer S17 hash board troubleshooting for report 0
The most common failure of Antminer hash boards is found out 0 ASIC chips. In case of such failures, first of all, it is necessary to check whether the power supply of the Antminer S17 hash board is normal. If it is abnormal, it needs to find out the abnormal power supply circuit first. If it is normal, then check whether the RI signal of the ASIC chip is normal. Only when the power supply voltage and RI signal are normal, the control board can recognize all ASIC chips on the hash board. -
Antminer S17 hash board troubleshooting for report incomplete chip
There are 48 ASIC chips on the Antminer S17 hash board. If the log shows other numbers, it means that the DC circuit and boost circuit of the S17 hash board is normal, and there is a fault in the signal transmission between ASIC chips. This video will explain in detail how to repair such faults, and demonstrate the specific repair operation steps. -
Antminer S17e hash board repair training tutorial
Antminer S17e hash board is made up of 15 voltage domains in series, each 9 ASIC chips connected in parallel is a domain, and the domain voltage is about 1.2V. Each domain of the S17e hash board has 2 1.8V LDO tubes and 2 0.8V PLL tubes, which together supply power to 9 chips in each domain. For more information on the S17e hash board, please watch the Antminer S17e hash board repair tutorial video. -
Antminer S17e hash board basics about the PIC chip
This video will explain the detection method and troubleshooting of the PIC chip on the Antminer S17e hash board. The PIC chip is used to store the operation information of the Antminer S17e hash board, and the control board provides 3.3V powering. If the output of the PIC chip is abnormal, the control board will not be able to communicate with the hash board, which will cause the entire hash board to stop running. -
Antminer S17e hash board basics about the boost circuit
The boost circuit of the Antminer S17e hash board is used to boost the input voltage from 18V to 23V. If the output of the boost circuit is abnormal, first check whether the resistance values of resistors R63 and R64 are normal, and then check whether the voltage of the pins of the boost chip is abnormal. This video will demonstrate the measurement method and troubleshooting of the boost circuit of the Antminer S17e hash board. -
Antminer S17e hash board U1 and U2 chip working process
Antminer S17e hash board has 2 level conversion chips located at U1 and U2. U1 is the level conversion chip of the CI signal, and U2 is the level conversion chip of the RI signal, both of which are used to convert the 3.3V input from the control board through the IO interface 1.8V output. Only when the level conversion chip works normally, the control board can recognize the hash board and communicate normally. -
Antminer T17 plus hash board repair tutorial
Antminer T17+ Hash board repair tutorial video mainly explains its main powering, domain powering, boost circuit, LDO powering, 5 signal transmission directions and temperature sensing circuit. When we repair the ASIC miner hash board, the first step is to judge whether the power supply of the hash board is normal, then check the signal transmission, and finally check whether the temperature sensing circuit is normal.
