7. Immediately after repairing the hash board, the thermal gel on the drinking water cooling board needs to be eliminated and reprinted.
Recently, a lot of firms proclaiming to be mining providers imitate us and say that they are related to us, or that they are our department providers, which has caused customers for being deceived.
Just before tests the pattern, the repaired hashboard need to cool down ahead of tests; usually, it will eventually result in tests NG.
As shown during the determine below, the 1st hash board has no hash level following operating for about 3 minutes.
3. In the event the PIC sensor NG is exhibited within the Liquid crystal display display with the hash board tester along with the take a look at read temperature is abnormal, then follow the steps under to troubleshoot: A) Test whether the 4 resistors of R24~R27 are welding abnormally, and Examine whether or not the welding of PIN2, three of U3 is ordinary; Figure five-thirteen B) Check whether or not the 4 temperature senses U4, R28~R30, U6, R31~R33, U7, R34~R36, U8, R37~R39 along with the matching resistance welding are abnormal, The placement of the temperature perception is revealed in Determine 5-14, the temperature sense is all Found about the back from the PCB, the resistance is located to the front with the PCB, and whether the temperature-delicate 3.3V electrical power supply is typical;
Or the two ASIC chips In this particular domain are not soldered appropriately. Many of them are because of small circuit of 0.8V and one.2V patch filter capacitors (evaluate the resistance of your patch filter capacitors connected with the back and front sides of the PCBA).
; Next, following the visual inspection is passed, the impedance of each and every voltage domain could be analyzed first to detect whether or not there is a limited circuit or Antminer s19 Hashboard an open up circuit. If Indeed, it must be dealt with first. On top of that, check whether the voltage of each and every area is about 0.36V.
When the EEPROM NG is exhibited over the Liquid crystal display display of the hash board tester, Verify whether or not the welding of U5 is ordinary.
Phase 7: The temperature sensor is situated to the side of chips, along with the resistor is situated around the entrance in the PCB. Check out the soldering of the temperature sensor IC, if the close by resistors are broken, and if the three.
Check the LCD Show ASICNG by measuring the entire voltage on the measuring area and Raise circuit.
Should the short-circuit is still present, you can unplug the CPU and evaluate again. Other voltage abnormalities usually change the corresponding voltage converter IC.
The strategy for repairing the issue is as follows: during the PT2 check, carefully keep an eye on the serial port print log. When the serial port has been functioning for an prolonged length of time, use a short-circuit probe to shorter-circuit RO and one.
It describes the troubleshooting of Bitmain Antminer S19 numerous faults, and points out how to utilize the examination resources for exact positioning.
