The 2-Minute Rule for antminer s19 hashboard repair
This case is generally due to irregular series resistance welding of CLK, CI, and BO on the entrance and rear of the X chip, so just give attention to examining these six resistors. There's a small probability that it is attributable to irregular welding of the subsequent pins in the 3 chips X-one, X, and X+one:
a) Once the card recovery is effectively, the environmentally friendly LED indicator might be generally on, and the facility shall be turned off and restarted;
8V, 1.8V patch filter capacitors (evaluate the resistance of your patch filter capacitors linked to the front and back with the PCBA)
When powering around the hashboard, join the adverse copper wire of the facility supply 1st, then the constructive copper wire of the power source, and finally, insert the sign cable.
a-three) Evaluate the resistance of R8 or R9 having a multimeter to examine whether it is inside of 10 ohms and the looking through is not going to bounce randomly. Otherwise, please swap both of these resistors
c) Should the hashboard even now shows the X and lessens the hashrate, it is possible to eliminate the heat sink in the hash board for mining. If the hashrate is lessen, evaluate if the domain voltage is standard.
Check the resources in order that the test fixture can work generally. Determine the parameters of the upkeep station take a look at program, the Edition on the test jig, and various associated parameters.

Pattern NG is a result of the big distinction between the features of your chip and other chips. At the moment, it truly is observed the chip die is destroyed, so just replace the chip. According to the log info, the replacement rules are as follows: If the appearance from the chip is not damaged, just switch the chip with the lowest response rate in Each individual domain.
Not too long ago, numerous corporations declaring being mining companies imitate us and say that they're related to us, or that they are our branch organizations, which has caused buyers to generally be deceived.
a) Liquid crystal display Display screen ASICNG: if (0), to start with evaluate the whole voltage of your measuring area along with the Improve circuit 19V is typical, after which use the shorter-circuit probe to brief-circuit the RO test issue as well as the 1V8 check point concerning the 1st and the second chip, after which you can run This system to discover the chip.
