10. If the nonces of most chips in your complete miner or single board are returned to 0, it is frequently a chip welding difficulty. Reinstall it and it'll be Alright.
Poor chip soldering or damage to the chip capacitor or resistor, or irregular resistance typically results in The problem.
c) Liquid crystal display Show ASIC113: (Reporting 113), it means that the hash board can detect 114 chips at 115200 baud level, but only 113 chips are uncovered at 12M baud amount, and 1 chip couldn't be found at 12M baud level; Repair strategy: Using the dichotomy system, limited-circuit the 1V8 examination place along with the RO check level among the 38th and 39th chips Along with the quick circuit probe. When the log can discover 38 chips, there is absolutely no challenge with the initial 38 chips; if shorter-circuiting the 47th chip, though the log studies forty sixth, it implies which the 47th chip can not be detected, and there's no problem While using the visual inspection. Frequently, the 47th chip shall get replaced; Determine 5-15 d) Liquid crystal display display ASICNG: (X, a certain chip is fixedly described), There's two situations: d-1) The very first situation: the exam time is basically the same as The nice board (commonly the value of X is not going to adjust every time you take a look at) (examination time refers to the time from when the beginning examination button is pressed to time when the results of ASICNG: (X) is shown about the Liquid crystal display). This case is likely for being attributable to the abnormal resistance welding in the entrance and rear CLK, CI, and BO of the Xth chip, so buyers shall center on these six resistors. The smaller likelihood is due to X-one, X, X+1, that may be, Amongst the three chips, the next pins irregular welding circumstances of the chip come about: Determine five-16 d-two) The next case: the exam time is almost 2 times as long as the good board (at times the worth of X will adjust when you take a look at, and in some cases X=0); right now, the log ordinarily has the next info (the red number is just not thirteen someday, dependant upon which seat the hash board tester is connected to); in the course of the test, believe which the area voltage of many of the fields before the irregular position is nearly below 0.3V, plus the area voltage from the back fields are Nearly all increased than 0.34V. This case is attributable to the chip not remaining soldered very Purchase Here well, typically one.8V, 0.8V, RXT, CLK are usually not soldered effectively. It is usually recommended to right evaluate the area voltage to Track down which area is the trouble. The 1V8 and RO small-circuit approach Utilized in part a) can also Track down the abnormal situation;
Revive your Antminer S19’s effectiveness with our top-notch substitute hashboards. Expertly refurbished to make certain exceptional mining performance, these hashboards are your Answer to faulty mining functions. Don’t let defective hashboards sluggish you down.
three. If the PIC sensor NG is exhibited around the Liquid crystal display screen of the hash board tester as well as take a look at browse temperature is abnormal, then Keep to the ways beneath to troubleshoot: A) Look at whether the four resistors of R24~R27 are welding abnormally, and Verify whether or not the welding of PIN2, three of U3 is usual; Determine 5-thirteen B) Examine whether or not the 4 temperature senses U4, R28~R30, U6, R31~R33, U7, R34~R36, U8, R37~R39 as well as the matching resistance welding are abnormal, the location on the temperature perception is demonstrated in Determine five-14, the temperature sense is all Situated about the back again of your PCB, the resistance is found about the front with the PCB, and whether the temperature-sensitive 3.3V electricity offer is usual;
If you have any dissatisfaction through the transaction or have precious recommendations for us, you should Call us by means of this electronic mail address:
four. Make the SD card In accordance with the necessities, double-sided heat sink, 8 occasions Parrer take a look at, you should make the SD card as shown while in the figure down below:
The D-Central team is a perfectly-proven and recognized authority in issues of ASIC repair. Our Teaching Class is customized to equip persons with the talents they have to tackle even the hardest repair jobs with self-confidence. The consulting services we offer supply our consumers with skilled assistance and aid, allowing them to have the most out of their repair classes.
PatternNG is due to the massive difference between the qualities from the chip and other chips. At present, it's found that the chip die is broken, so just swap the chip. Based on the log information and facts, the replacement procedures are as follows:
(1) Unexpected electricity failure in the course of OTP or time of less than 30s will cause the Command board to fall short to open up the OTP operate.
Continue this process and brief-circuit the following chips one after the other until eventually a chip is found that also will cause long-expression functioning failure even just after remaining shorter-circuited. This failure will likely be due to harm to that specific chip, and so it ought to be replaced.
three. The test SD card will probably be made As outlined by the requirements, along with the double-sided heat sink 8-periods Patter check ought to make an SD card, as demonstrated within the figure underneath;
It describes the troubleshooting of Bitmain Antminer S19 different faults, and describes how you can utilize the take a look at tools for exact positioning.
one. Seek advice from the voltage worth range described from the sign craze. When the measurement encounters a large deviation on the voltage value, it may be compared Along with the calculated worth of the adjacent team to determine.
