This situation is mostly due to irregular collection resistance welding of CLK, CI, and BO to the front and rear from the X chip, so just deal with examining these 6 resistors. There's a modest chance that it's caused by irregular welding of the subsequent pins from the 3 chips X-one, X, and X+1:
a) After the card recovery is productively, the environmentally friendly LED indicator might be normally on, and the ability shall be turned off and restarted;
3V power offer is usual; Check the welding high quality in the chip which connects sensor and the modest heat sink. The deformation of huge warmth sink material will result in very poor warmth dissipation with the chip and influence the temperature change. Figure five-thirteen 3. Phenomenon: One board detection chip is just not comprehensive (PT1/PT2 stations)
8V ranging from the very first chip. When the serial port stops long-phrase Procedure following the limited circuit, the very first chip is functioning appropriately.
; Next, once the Visible inspection is handed, the impedance of each and every voltage area is often examined first to detect whether or not There exists a small circuit or an open circuit. If found, it needs to be addressed first. Also, Look at whether or not the voltage of every area is about 0.36V.
b) Enter the person title, password along with the exam command to begin to see the NONCE return status and also the status of the voltage area. If there is abnormality in NONCE and area voltage, it can be repaired in accordance with the abnormal chip printed.
② An additional repair method: Log in on the IP throughout the "Putty" software program to check whether the area functioning voltage of the hash board is typical, and if the nonce return is ordinary, and you can repair according to the log info on the "Putty" software.
Open up MPLABIPE and select device: PIC16F1704, click on electrical power to select the power provide mode, then click on run. Step one: decide on "file" to find the .HEX file to become programmed; the next move: click on "join" to connect Generally; the 3rd step: click on the "plan" button, and right after completion, click on "confirm" to prompt the verification to prove that the programming is effective.
At that time, Microsoft Promotion will use your total IP handle and person-agent string in order that it could thoroughly procedure the ad click on and demand the advertiser.
In keeping with this method, discover the chip that still has the long-expression functioning failure just after a particular chip is short-circuited. Generally, it truly is attributable to a particular chip harming, so just change it;
Continue on this process and quick-circuit the following chips one after the other until finally a Antminer s19 Pro Hashboard chip is located that still causes long-time period running failure even soon after getting brief-circuited. This failure is often resulting from harm to that exact chip, and so it should be changed.
3. The exam SD card is going to be made As outlined by the necessities, as well as the double-sided heat sink 8-instances Patter take a look at ought to make an SD card, as shown within the figure under;
Repair approach: check the appearance, evaluate the chip capacitor or resistor in entrance, it is normally because of very poor soldering from the chip or simply a weakened chip capacitor or resistor or abnormal resistance price;
