antminer s19 hashboard repair Fundamentals Explained

Blog Article

 This example is generally brought on by irregular collection resistance welding of CLK, CI, and BO on the front and rear with the X chip, so just deal with examining these 6 resistors. You will find there's little probability that it is due to abnormal welding of the subsequent pins from the three chips X-one, X, and X+1:

Get the very best mining general performance out of your Antminer S19 by using the ideal software package. Sign up for minerstat and discover the best suited program on your set up.

Phase 3: Click on the “application” button. Following completion, click on “confirm”. It will eventually prompt that the verification is done to show that the burning is successful.

Servicing process: Look at the appearance and measure the capacitance or resistance of your front chip. Typically, it really is because of lousy chip welding or damage and abnormal resistance of a particular chip capacitor or resistor, or issues with the chip itself;

3V, as well as area voltage from the back again fields are Virtually all higher than 0.38V. This situation is due to the chip not becoming soldered properly, normally one.8V, 0.8V, RXT, CLK are not soldered perfectly. It is recommended to immediately evaluate the area voltage to Identify which domain is the condition. The 1V8 and RO short-circuit method used in segment a) might also Identify the irregular place;

(two) If the looks from the chip is not really harmed, just change the chip with the lowest response amount in Every single domain;

Kernel Log: it keeps records of ANTMINER's operation phases, which serves as a way to troubleshoot some common problems. The tactic to enter the miner log: enter the miner IP handle inside the tackle bar of Google or Firefox browser >> enter the user name/password (default root/root) >> the miner log

Open up MPLABIPE and choose product: PIC16F1704, simply click electric power to choose the facility supply mode, then simply click function. The initial step: decide on "file" to discover the .HEX file for being programmed; the second move: click on "link" to attach Commonly; the 3rd move: simply click the "system" button, and immediately after completion, click "confirm" to prompt the verification to demonstrate which the programming is successful.

PS: If the hashboard just isn't driven or driven off according to the check sequence, triggering R8, R9, U1, and U2 to burn out, the chip will report 0;

a-4) Test In case the pins of the main chip are soldered effectively (it was found during repair the pins are tinned observing within the side, even so the pins will not be stained with tin in the least when the chip is eliminated)

a) Following the card recovery is passed, the eco-friendly LED indicator is going to be constantly on, and the power shall be restarted;

Referring to the test method document, the overall difficulties that crop up are assembly course of action difficulties and control board course of action issues. Widespread problems consist of The shortcoming to detect the IP, irregular range of detected followers, and abnormal detected chain.

In summary, this repair strategy requires examining Just about every chip in sequence by limited-circuiting them Go Here and monitoring the serial port Procedure until eventually the faulty chip is determined and changed.
