two. Once the EEPROM NG is displayed on the LCD monitor of the hashboard tester, Examine whether or not the welding of U5 is ordinary;
Our Antminer S19Pro hashboard is the ideal solution to repair and replace any malfunctioning or small-performing Bitcoin miner S19 Professional. By cutting down downtime and losses, you'll be able to increase your mining income and optimize profitability.
In case the miner whose Management board is flashed must start out Usually, the subsequent two techniques are needed:
Should you have any dissatisfaction in the transaction or have beneficial strategies for us, be sure to Call us by means of this e-mail deal with:
③ Make use of a multimeter to evaluate the resistor of R8 or R9 to see whether it is inside of 10 ohms, and the reading is not going to jump randomly. Otherwise, exchange the two resistors;
Or the two ASIC chips In this particular area will not be soldered thoroughly. Many of them are brought on by quick circuit of 0.8V and one.2V patch filter capacitors (evaluate the resistance of the patch filter capacitors relevant to the back and front sides with the PCBA).
; Next, after the visual inspection is passed, the impedance of each and every voltage domain might be tested to start with to detect whether You will find there's small circuit or an open up circuit. If Indeed, it should be handled to start with. Also, Examine if the voltage of every area is about 0.36V.
8. To replace a completely new chip, printing pins and soldering paste are required to make certain that the chip is pre-soldered after which soldered to your PCBA for repair
Proceed to research with dichotomy right up until the problematic chip is found. Assuming that there is a difficulty with the Nth chip, once the 1V8 and RO amongst the N-1th and Nth chips are small-circuited, N-one chips are available, but in the event the 1V8 and RO concerning the Nth and N+1th chips are limited circuited, your complete chip can not be observed.
five. During the check of repairing and changing the chip, the chip really should be tested initially, and afterwards the operate exam shall be performed after passing. The purpose take a look at must ensure that the smaller warmth sink is welded qualified.
① To start with, visually inspect the hash board to determine if there is any deformation or burning in the PCB. If there is any phenomenon, it has to be handled 1st.
Does any data on this page appears incorrect and you prefer to for us to check it? Make clear the issue with just as much information and facts as possible.
a-three) Evaluate the resistance of R8 or R9 with a multimeter to examine whether it is in just ten ohms and the reading will not jump randomly. If not, make sure you exchange both of these resistors. a-4) Examine If your Look Here pins of the first chip aren't soldered nicely (it absolutely was found in repair which the pins are tinned observing from the facet, though the pins are certainly not stained with tin in any way once the chip is eliminated). b) If 1 chip are available in step a), it signifies that the initial chip as well as the prior circuit are good. Use the same method to check the next chips. One example is, quick-circuit the 1V8 examination place along with the RO check place involving the 38th and 39th chips. If the log can discover 38 chips, the primary 38 chips don't have any issue; if you still discover 0 chips, check the 1V8 1st; if it's standard, it means that there's a dilemma Using the chip immediately after 38. Continue to research with dichotomy until eventually the problematic chip is discovered. Assuming that there is a difficulty Along with the Nth chip, if the 1V8 and RO between the N-1th and Nth chips are shorter-circuited, N-one chips can be found, but once the 1V8 and RO amongst the Nth and N+1th chips are quick circuited, the whole chip cannot be identified.
PS: When the hash board will not be run or powered off based on the examination sequence, resulting in U2 and U10 to melt away out, it will report 0 when tests the chip;
