a-four) Verify In the event the pins of the primary chip usually are not soldered perfectly (it absolutely was located in repair which the pins are tinned observing in the aspect, though the pins will not be stained with tin in any respect in the event the chip is removed)
Our Antminer S19Pro hashboard is the ideal solution to repair and replace any malfunctioning or very low-carrying out Bitcoin miner S19 Professional. By lowering downtime and losses, you are able to boost your mining revenue and optimize profitability.
; secondly, after the Visible inspection is passed, the impedance of each and every voltage area might be analyzed initial to detect regardless of whether You will find there's small circuit or an open up circuit. If observed, it should be handled very first. In addition, Verify whether the voltage of each area is about 0.36V.
8V starting from the first chip. If the serial port stops long-term Procedure once the quick circuit, the first chip is performing adequately.
five. When powering about the hash board, it's essential to first hook up the unfavorable copper wire of the power offer, then the good copper wire in the PSU, And at last insert the sign cable. When disassembling, the order of set up must be reversed, initially take out the signal cable, then remove the beneficial copper wire of the ability offer, And eventually take away the adverse copper wire of the ability provide.
3. In case the‘PIC sensor NG’is exhibited to the LCD monitor in the hashboard tester and also the examined temperature is irregular, then follow the techniques beneath to troubleshoot:
Servicing method: Through the PT2 test, look at the serial port print log. It is frequently caused by an error while in the sign-up address of a specific chip. Just swap the BM5 chip as revealed in Determine five-19 (asic starts off from 0).
b. Look at whether or not the inlet air temperature of your miner is just too superior, and ensure which the exhaust air is clean.
b) If 1 chip can be found in move a), it implies that the very first chip along with the past circuit are fantastic. Use an identical process to examine the subsequent chips. For instance, quick-circuit the 1V8 examination stage and also the RO take a look at stage in between the 38th and 39th chips. In the event the log can find 38 chips, the first 38 chips haven't any dilemma; if you still find 0 chips, Look at the 1V8 initially; if It is really usual, this means that there is a problem with the chip immediately after 38.
The fan will alarm and it will not perform Commonly. Typically, the ambient temperature is just too substantial, and the irregular operation in the admirer can even induce abnormal temperature.
● When locating the faulty chip, the chip should be welded once again. The tactic is so as to add flux within the chip (preferably no-clean up flux), and heat the solder joints of the chip pins to the dissolved point out to prompt the chip pins and pads to re-run in and obtain the tin, In order to accomplish the effect of tinning all over again. In the event the fault stays the exact same after re-soldering, you could directly replace the chip.
Home windows mining Our mining checking and Look Here management software for Home windows GPU rigs is the ideal Answer for many who choose to mine on their Home windows equipment.

Make reference to the voltage value range explained through the signal trend. When the measurement encounters a sizable deviation of the voltage price, it may be when compared Along with the measured worth of the adjacent team to determine.
