In the event the link is OK, the user can exam the single board PT2 to check if it might go the exam. If it passes the check, it could possibly in essence be determined that the issue is to the control board. In case the test fails, use the PT2 repair system to repair it.
Repair system: Verify the appearance, measure the chip capacitor or resistance in entrance, usually It truly is because of bad chip soldering or perhaps a chip capacitor, resistor detrimental or irregular resistance; VI. Command Board Dilemma Resulting in the next Troubles one. The whole miner does not operate 1) Examine if the voltages at a number of voltage output points are usual. U8 can be disconnected initial if 3.3V is brief-circuited. If it remains brief-circuited, the CPU might be unplugged for measurement. For other voltage abnormalities, frequently switch the corresponding converter IC. 2) In case the voltage is typical, make sure you Look at the welding status of your DDR/CPU. three) Try and update the flash system with SD card; If the miner of which the Regulate board continues to be reflashed needs to start out normally, the next two steps are demanded: a) Once the card recovery is passed, the eco-friendly LED indicator is going to be normally on, and the ability shall be restarted; b) Look forward to 30s soon after powering on all over again (some time system of turning on OTP).
c) LCD Screen ASIC113: (Reporting 113), it signifies that the hash board can detect 114 chips at 115200 baud price, but only 113 chips are located at 12M baud charge, and a person chip couldn't be uncovered at 12M baud fee; Repair strategy: Utilizing the dichotomy approach, short-circuit the 1V8 examination stage and the RO take a look at issue amongst the 38th and 39th chips Together with the small circuit probe. When the log can discover 38 chips, there isn't any dilemma with the primary 38 chips; if limited-circuiting the 47th chip, though the log experiences forty sixth, it implies the 47th chip can not be detected, and there is no dilemma Using the Visible inspection. Usually, the 47th chip shall be replaced; Determine five-15 d) LCD Exhibit ASICNG: (X, a certain chip is fixedly described), there are two conditions: d-one) The primary scenario: the test time is essentially the same as The great board (ordinarily the value of X is not going to improve each time you check) (check time refers back to the time from when the beginning examination button is pressed to time when the results of ASICNG: (X) is exhibited within the LCD). This example is likely being because of the abnormal resistance welding in the front and rear CLK, CI, and BO of your Xth chip, so consumers shall give attention to these 6 resistors. The tiny probability is because of X-1, X, X+one, that's, Amongst the 3 chips, the next pins abnormal welding disorders with the chip occur: Figure five-16 d-two) The next circumstance: the examination time is almost twice as long as The nice board (occasionally the worth of X will alter each and every time you check, and at times X=0); at the moment, the log usually has the following details (the crimson amount is not 13 someday, based upon which seat the hash board tester is connected to); over the take a look at, assume that the area voltage of all the fields in front of the irregular posture is nearly below 0.3V, and also the area voltage of the back again fields are Pretty much all greater than 0.34V. This example is attributable to the chip not staying soldered properly, ordinarily one.8V, 0.8V, RXT, CLK are certainly not soldered perfectly. It is suggested to specifically evaluate the domain voltage to Track down which area is the issue. The 1V8 and RO limited-circuit system Utilized in section a) also can locate the abnormal place;
Repair approach: in the course of the PT2 examination, Test the serial port print log. In the event the serial port starts to operate to get a long time, use a brief-circuit probe to shorter-circuit RO&one.
As for the issue which the Management board are unable to start out (not networked), the person desires to switch the U1 (most important Regulate IC FBGA of Management board). U1 can no longer be Utilized in 19 series following substitution
Recently, several corporations boasting being mining providers imitate us and say that they are associated with us, or that they are our branch firms, that has induced clients to be deceived.
2. Make the SD tests card In line with the necessities, and specifically unzip the compressed offer of the single-sided heat sink inspection chip to help make the SD card;
2. Soon after there aren't any problems in program testing (small circuit detection in schedule tests is usually important to stay away from burning the chip or other components as a result of small circuit when electricity is on), the examination fixture can be utilized to detect the chip, as well as the positioning may be determined based upon the check fixture detection results.
2. Growing older test: In the aging take a look at, repair should be carried out in accordance with the monitored interface check, for instance:
The fan will alarm and it'll not work Ordinarily. Frequently, the ambient temperature is simply too superior, as well as abnormal operation of your lover will even result in abnormal temperature.
● When locating the faulty chip, the chip has to be welded all over again. The method is to incorporate flux round the chip (preferably no-clear flux), and warmth the solder joints of your chip pins to some dissolved point out to prompt the chip pins and pads to re-operate in and collect the tin, so as to attain the impact of tinning again. Should the fault remains the same following re-soldering, you are able to straight switch the chip. ● The repaired hash board is usually judged as an excellent product or service with greater than two passes when tests with the hash board tester. For the first time, following replacing the parts, await the hash board to cool down, utilize the hash board tester to check, and following the examination is passed, established it apart and after that interesting it down. For the next time, soon after a couple of minutes if the hash board cools down, examination once more. 0 About items acquire, make sure you Get in touch with our sales manager:
This spare element is exclusively designed for uncomplicated servicing and repair on the S19 Professional hash board, making certain seamless functions and significant-performance mining.
Referring for the check method doc, the overall difficulties are assembly system challenges and Management board procedure problems.
Continue to research with dichotomy until finally the problematic chip is found. Assuming that there is a problem Along with the Buy Here Nth chip, if the 1V8 and RO among the N-1th and Nth chips are shorter-circuited, N-1 chips can be found, but once the 1V8 and RO among the Nth and N+1th chips are limited circuited, all the chip cannot be uncovered.
