38. Proceed to use the binary strategy to examine until eventually the problematic chip is identified. Assuming that there's a trouble with the Nth chip, once the 1V2 and RX between the N-1th chip along with the Nth chip are brief-circuited, the N-1 chip are available; Nevertheless, once the 1V2 and RX involving the N and N+one chips are quick-circuited, the complete chip cannot be located.
7. When powering about the hash board, the damaging copper wire of the ability provide should be connected first. Ahead of screening the sample, the repaired hash board needs to be cooled down ahead of screening, if not it'll bring about exam PNG.
Once the defective chip is situated, weld the chip yet again by including flux within the chip and heating the solder joints in the chip pins into a dissolved state. This may prompt the chip pins and pads to re-run in and acquire the tin, obtaining the outcome of tinning again.
According to this process, locate the chip that also has the long-tem operating failure immediately after a particular chip is short circuited. Commonly, it really is a result of a particular chip damaging, so just switch it; Figure 5-19 seven. Phenomenon: PT1 chip examination is Alright, PT2 purpose test normally stories a certain chip NG.
3V, plus the domain voltage from the back again fields are Virtually all larger than 0.38V. This situation is because of the chip not currently being soldered nicely, usually one.8V, 0.8V, RXT, CLK usually are not soldered well. It is usually recommended to immediately evaluate the domain voltage to Find which domain is the issue. The 1V8 and RO small-circuit method Employed in part a) can also Find the irregular situation;
3. In the event the‘PIC sensor NG’is displayed within the Liquid crystal display display with the hashboard tester as well as the analyzed temperature is abnormal, then Adhere to the ways down below to troubleshoot:
four. Make the SD card In accordance with the necessities, double-sided heat sink, eight instances Parrer check, you should make the SD card as demonstrated within the figure underneath:
Does any knowledge on this page looks incorrect and you want to for us to check it? Explain the issue with just as much info as possible.
Does any information on this web site appears to be incorrect and you desire to for us to examine it? Explain The problem with just as much information as possible.
Don’t Permit faulty hashboards influence your mining efficiency. Upgrade your Antminer S19 Pro with our dependable and superior-doing substitution hashboards nowadays.
Should the brief-circuit is still existing, you can unplug the CPU and evaluate once again. Other voltage abnormalities frequently replace the corresponding voltage converter IC.
The hash board is an important ingredient of a copyright mining device. If It's not performing adequately, it could cause serious challenges. This text aims to provide troubleshooting measures for widespread faults related to the hash board.
It describes Buy Now the troubleshooting of Bitmain Antminer S19 different faults, and explains ways to make use of the check tools for precise positioning.
