two. When the EEPROM NG is exhibited over the LCD monitor of the hashboard tester, Look at whether or not the welding of U5 is ordinary;
If the exam chip isn't totally detected, the board ought to be repaired. Whether it is typical once the exam, take out the hash board independently, use the examination fixture to carry it in to the Debug master software to mine, and modify the supporter speed to 95%.
c) LCD Screen ASIC113: (Reporting 113), it means that the hash board can detect 114 chips at 115200 baud charge, but only 113 chips are discovered at 12M baud level, and a person chip couldn't be located at 12M baud rate; Repair method: Utilizing the dichotomy method, short-circuit the 1V8 exam level and the RO exam issue involving the 38th and 39th chips Together with the short circuit probe. When the log can discover 38 chips, there is not any dilemma with the main 38 chips; if short-circuiting the 47th chip, nevertheless the log reports forty sixth, it signifies that the 47th chip can't be detected, and there's no trouble Using the Visible inspection. Commonly, the 47th chip shall get replaced; Determine 5-fifteen d) Liquid crystal display Exhibit ASICNG: (X, a particular chip is fixedly claimed), There are 2 situations: d-1) The 1st scenario: the examination time is essentially similar to The great board (commonly the value of X is not going to change each time you exam) (examination time refers to the time from when the beginning exam button is pressed to time when the results of ASICNG: (X) is shown on the Liquid crystal display). This situation is probably going to be because of the irregular resistance welding on the entrance and rear CLK, CI, and BO of the Xth chip, so buyers shall concentrate on these six resistors. The smaller likelihood is because of X-1, X, X+one, that is, Amongst the 3 chips, the next pins irregular welding disorders in the chip happen: Determine 5-16 d-2) The next situation: the exam time is nearly twice as long as The nice board (in some cases the worth of X will transform every time you take a look at, and occasionally X=0); at this time, the log commonly has the following information and facts (the red range just isn't thirteen sometime, determined by which seat the hash board tester is linked to); during the exam, believe which the area voltage of the many fields in front of the abnormal position is almost below 0.3V, along with the area voltage of your back again fields are Virtually all increased than 0.34V. This case is because of the chip not remaining soldered well, ordinarily one.8V, 0.8V, RXT, CLK are certainly not soldered nicely. It is suggested to directly measure the domain voltage to Identify which area is the issue. The 1V8 and RO short-circuit strategy Utilized in part a) may also locate the abnormal posture;
Our Antminer S19Pro hashboard is the best Alternative to repair and swap any malfunctioning or small-performing Bitcoin miner S19 Professional. By decreasing downtime and losses, you are able to improve your mining income and increase profitability.
Utilize the hashboard tester from the V2.2010 control board. The constructive and destructive poles on the tester must be mounted with discharge resistors. It is suggested to implement a cement resistor of twenty five ohms and a lot more than 100W.
three. If your‘PIC sensor NG’is shown over the LCD display screen of your hashboard tester along with the analyzed temperature is irregular, then follow the measures below to troubleshoot:
② A different repair process: Log in for the IP with the "Putty" application to examine whether the area running voltage of the hash board is usual, and if the nonce return is typical, and you will repair in accordance with the log info on the "Putty" software package.
Check out the welding high quality of the heat-sensitive chip and the smaller warmth sink. The deformation of the massive warmth sink product will induce very poor warmth dissipation on the chip and influence the temperature variation.
We will also give guidelines regarding how to use Putty program to diagnose issues with the NONCE response status and area voltage concentrations. Using this tutorial, you’ll have all the knowledge necessary to maintain your Antminer S19 running at exceptional general performance.
seven. When powering around the hashboard, user have to to start with connect the unfavorable copper wire of the power offer, then the favourable copper wire of the facility offer, And eventually plug during the sign cable. When taking away, the purchase of installation has to be reversed. Very first get rid of the sign cable, then get rid of the optimistic copper wire of the power offer, and finally remove the destructive copper wire of the ability offer.
① First off, visually inspect the hash board to view when there is any deformation or burning with the PCB. When there is any phenomenon, it has to be dealt with very first.
3. Just after repairing, the hash board need to be analyzed over two periods to be OK right before it could pass! 4. Test whether or not the applications and hash board testers can function Typically, determine the maintenance station to test application parameters, examination fixture versions, and so on. 5. In the take a look at of repairing and changing the chip, the chip ought to be examined initial, and afterwards the perform check shall be performed after passing. The function examination ought to make sure the smaller heat sink is welded skilled. When setting up the massive warmth sink, the floor of your chip should be evenly coated with thermal gel and also the cooling fan shall be at total speed. When using the chassis to dissipate warmth, 2 hash boards really should be positioned at the same time to variety an air duct. 6. When measuring the signal, use 4 admirers as support for warmth dissipation, along with the enthusiasts shall retain total pace. seven. When powering around the hash board, the consumer have to initial hook up the negative copper wire of the ability provide, then the positive copper wire of the power provide, And at last plug within the sign cable. When removing, the order of installation should be reversed. Very first, get rid of the signal cable, then take away the favourable copper wire of the facility offer, and finally take away the detrimental copper wire of the ability provide. When the consumer does not comply with this purchase, it is extremely easy to induce harm to R8, R9, U1, U2 (not all chips can be found). Just before testing the sample, the repaired hash board have to be cooled down in advance of screening, in any other case, it may trigger PNG testing. eight. To exchange a fresh chip, printing pins and soldering paste are needed to make certain that the chip is pre-soldered and then soldered into the PCBA for repair. III. hash board tester generating and issues needing awareness The supporting fixture of the hash board tester need to satisfy the heat dissipation with the hash board and facilitate the measurement of indicators. one. Utilize the 19 sequence hash board tester SD card swiping system for The 1st time to update the hash board tester Handle board FPGA, unzip it and replica it to the SD card, after which insert the cardboard into the hash board tester card slot; electric power on for approximately one minute and wait for the Management board indicator to double flash three situations, then the update is accomplished; (if It's not at all current, it may well trigger a particular chip to get bad through the examination). Figure 3-1 2. Make the examination SD card In keeping with the necessities, and specifically unzip the compressed package deal of The one-sided warmth sink inspection chip to help make the SD card; Determine three-two three. The exam SD card will be produced In keeping with the requirements, and also the double-sided warmth sink 8-instances patter exam has to make an SD card, as shown in the determine beneath;
Repair strategy: Verify the looks, evaluate the chip capacitor or resistor in front, it is frequently a result of inadequate soldering of the chip or maybe a broken chip Order Now capacitor or resistor or irregular resistance benefit;
Also, these recommendations also needs to include things like Directions on cleaning elements with accredited solvents which include isopropyl Alcoholic beverages or distilled water, as well as the way to retail store factors clear of extreme temperatures and humidity ranges securely. Finally, routinely scheduled upkeep checks ought to be carried out every few months or at the least annually to ensure the correct functioning of all pieces in the program.
