The log shows: SYSTEMSTATU[Work: Out Over Hot, Hash Board: 3 ]
BOOTBY[0x04.00000000]
Temp[24] TMax[116] TAvg[58] Fan1[0] Fan2[0] Fan3[0] Fan4[0]
MTmax[77 116 83]
ECHU[1 1 1] ECMM[197] BitMaxz is right. The chip temperature on the middle board is too high. One chip's temperature reached 107, while another's reached 116. So, you need to check and repair the hash board in the middle.

Bitcoin / Mining support / Antminer S19 hydro manual

1. S19 Hydro hash board working structure: The hash board consists of 104 BM1398 chips (silk screen sequence BM1-BM104) divided into 52 groups (domains), each group consisting of 2 ICs. The BM1398 chip used in the S19 Hydro hash board operates at 0.37V. Groups 52, 51, 50, 49, 48, 47, and 46 (7 groups in total), the 25V output by the boost circuit U9 supplies power to the LDO and outputs 1.8V. Group 45 to Group 1 are provided 1.8V by VDD 18V through LDO. Each time one domain is moved back, the domain voltage decreases by 0.37V. All 0.8V is provided by the 1.8V of this domain through the LDO output:    2. S19 Hydro hash board boost circuit: The boost circuit converts the power from 19V to 25V.  3. S19 Hydro chip signal direction: CLK signal flow direction: generated by Y1 and Y2 crystal oscillator 25M. Y1 is transmitted from BM1 chip to BM51 chip. Y2 is transmitted from the BM52 chip to the BM104 chip, and the voltage is about 0.9V. TX (CI, CO) signal flow direction: from the 7th pin (3.3V) of the IO interface to the level conversion IC U2, and then transmitted from the BM1 chip to the BM104 chip. When the IO cable is not plugged in, the voltage in standby is 1.8V and the voltage in operation is 0.6V. RX (RI, RO) signal flow direction: from BM104 chip to BM1 chip, back to pin 8 of the signal cable terminal via U1, and then back to the control board. The voltage is 0.3V when the IO cable is not plugged in, and the voltage is 1.8V during operation. BO (BI, BO) signal flow direction: from BM1 chip to BM104 chip, measured by multimeter is 0V. RST signal flow direction: from the 3rd pin of the IO interface to D2, R13, R14, and then transmitted from chip 01 to chip 104. When the IO cable is not plugged in, it is 0V in standby and 1.8V during operation.  Source: Antminer S19 Hydro Hash Board Repair Guide | Zeus Mining |

When running chain[2], the number of ASIC chips read is 0, so the power is off. You can check that the cable connection between the chain[2] hash board and the control board is correct, as well as remove the hash board and clean the dust. If this is still 0, it's best to use the Antminer test fixture to check if the single board can find the chip.

Hi, this is the Antminer ASIC chip adaptation table compiled by ZEUS MINING.  Among them, the number of ASIC chips in the same series of machines may be different. For example, the number of ASIC chips on a hash board of Antminer S19 95T is 76, but the number of chips on a 90T hash board maybe 88 or 126. The S19j pro hash board has 126 BM1362 chips and the S19XP hash board has 110 BM1366 chips. If you want to know the exact amount, you need to look at the markings on the hash board. |

2023-11-30 13:42:30 Chain[0]: find 82 asic, times 0
2023-11-30 13:42:32 Chain[0]: find 82 asic, times 1
2023-11-30 13:42:34 Chain[0]: find 81 asic, times 2
2023-11-30 13:42:34 Chain 0 only find 81 asic, will power off hash board 0
Please check whether the cable is connected properly. If there is no problem with the cable, use the test fixture to test the board. |

hey, two of the heatsinks fell off one of the hashboards on my s17+, they also ripped off the cpu chip.
i got replacement chips and soldering equipment, however i never repaired asic before, so, from zero knowledge, how long do you expect this would take to repair?
Hey, I would like to share with you the ASIC miner repair course launched by ZEUS MINING, referred to as ZMRC. Our courses start from the basics. If you are interested, you can view our course content here. https://course.zeusbtc.com/If you have maintenance experience, you can also discuss some fault phenomena with our technicians, who will provide free support. |

The Antminer S9 hash board uses high-temperature solder paste and requires temperatures above 400 degrees Celsius to melt it. And when disassembling the capacitor, adding some new tin will help the old solder dissolve faster.

When ECMM[1] is displayed, it indicates that the Control board may be faulty or improperly connected to the Hash board.
If you change the cables and still no change, the control board or adapter board may be faulty. Try replacing it with a new control board or adapter board to see if it works properly.
