Blog Article

three) Endeavor to update the flash system with SD card;Should the Manage board card recovery equipment must commence Commonly, the subsequent two ways are required:

Question the log, if the following is shown, it means that the hashboard has number of chips or the hashboard has not detected it.

3V power offer is regular; Examine the welding high-quality of the chip which connects sensor and the modest heat sink. The deformation of enormous heat sink product will trigger inadequate heat dissipation in the chip and have an impact on the temperature variance. Figure 5-13 three. Phenomenon: Single board detection chip just isn't entire (PT1/PT2 stations)

Evaluate whether the domain voltage is normal. Frequently, the domain voltage will probably be irregular from the problematic domain. Then measure the RI signal to view if the RI sign is damaged. In case the RI signal is missing, essentially, the chip is brief-circuited or broken right after getting tinned.

For that Liquid crystal display display ASIC75, brief-circuit the 1V8 take a look at stage and also the RO examination place involving the 38th and 39th chips. If small-circuiting 47 chips, nevertheless the log stories forty six, it indicates that the 47th chip can not be detected, as well as 47th chip has to get replaced.

③ Following the visual inspection is Alright, the impedance of every voltage area might be detected to detect irrespective of whether There exists a limited circuit or an open circuit. If identified, it needs to be handled very first.

three. Following repairing, the hashboard need to be analyzed for much more than two moments to be Alright right before it could possibly move!

Examine the serial port log, if 0 chip is still uncovered at this time, It will likely be among the subsequent situations:

If you don't stick to this purchase, it's very simple to cause damage to U1 and U2 (not all chips can be found); In advance of screening the pattern, the repaired hash board needs to be cooled down prior to tests, or else it is going to bring about testing PNG.

(one) Unexpected power failure or under 30s in the entire process of opening OTP will trigger the Manage board to are unsuccessful to open up the OTP function, and also the Regulate board is not going to get started (not connected to the web).

① To start with, visually inspect the hash board to check out when there is any deformation or burning on the PCB. When there is any phenomenon, it should be addressed first.

3. The take a look at SD card is going to be made Based on the requirements, and the double-sided heat sink 8-periods Patter examination must make an SD card, as revealed in the determine beneath;

Repair approach: Verify the looks, measure the chip capacitor or resistor in entrance, it is normally due to inadequate soldering of the chip or a harmed chip capacitor or resistor or abnormal resistance value;

The voltage of every voltage area is about 0.36V. When there is 14V power supply, normally it's got area Antminer s19 Hashboard voltage. The priority is presented to evaluate the output of the power offer terminal of your hashboard and whether the MOS is short-circuited (measure the resistance amongst pins one, 4 and 8). If 14V has electricity offer but no area voltage, continue to examine.
