2. In the event the EEPROM NG is exhibited on the LCD display screen on the hashboard tester, Test if the welding of U5 is typical;
Repair process: Check out the appearance, evaluate the chip capacitor or resistance in front, usually It is really because of very poor chip soldering or perhaps a chip capacitor, resistor detrimental or irregular resistance; VI. Management Board Trouble Producing the Following Difficulties 1. The full miner does not function one) Look at whether or not the voltages at quite a few voltage output details are usual. U8 can be disconnected initial if 3.3V is short-circuited. If it continues to be quick-circuited, the CPU is usually unplugged for measurement. For other voltage abnormalities, usually exchange the corresponding converter IC. two) Should the voltage is usual, you should Verify the welding position with the DDR/CPU. three) Endeavor to update the flash plan with SD card; In the event the miner of which the Handle board continues to be reflashed has to start Typically, the subsequent two methods are essential: a) After the card Restoration is passed, the environmentally friendly LED indicator will probably be always on, and the power shall be restarted; b) Watch for 30s following powering on yet again (time program of turning on OTP).
Does any info on this website page appears to be like incorrect and you want to for us to examine it? Clarify the issue with as much facts as possible.
eight. To replace a fresh chip, printing pins and soldering paste are necessary making sure that the chip is pre-soldered and after that soldered into the PCBA for repair
To summarize, the repair procedure to the hash board will involve program inspection, chip take a look at, fault localization, and screening and verification. Via these measures, the faulty chip might be Found and repaired or replaced, and the hash board is usually examined to make certain it truly is working adequately.
d-two) The 2nd situation; the exam time is almost 2 times as long as the good board (at times the worth of X will alter when you exam, and at times X=0); right now, the log usually has the subsequent facts (the crimson range is not thirteen sometime, dependant upon which seat the hashboard tester is connected to); throughout the check, suppose the domain voltage of each of the fields before the abnormal situation is sort of fewer than 0.
This hash board is well-made and is apparently created to last. It provides constant performance and suits my mining devices properly.
Examine the welding good quality of the heat-delicate chip plus the tiny heat sink. The deformation of the large heat sink content will result in poor warmth Go Here dissipation with the chip and have an impact on the temperature distinction.
If you do not adhere to this buy, it is very very easy to trigger damage to U1 and U2 (not all chips can be found); In advance of screening the sample, the repaired hash board have to be cooled down before testing, normally it can result in testing PNG.
(1) Unexpected ability failure or fewer than 30s in the process of opening OTP will trigger the Manage board to are unsuccessful to open up the OTP purpose, and also the Manage board will not likely commence (not connected to the Internet).
In case you have any dissatisfaction in the course of the transaction or have worthwhile recommendations for us, be sure to contact us by means of this email handle:
Repair process: Utilizing the dichotomy strategy, limited-circuit the 1V8 examination position and also the RO test issue involving the 38th and 39th chips throughout the limited-circuit probe. When the log can discover 38 chips, there is absolutely no issue with the first 38 chips; if shorter-circuiting forty seven chips, even so the log reports 46, it suggests that the 47th chip can not be detected, and there is no trouble Along with the Visible inspection. Usually, the 47th chip shall get replaced;
two) Less hyperlink: Much less hyperlink refers to that among the three boards, 1 piece is missing. Generally, there is a problem with the relationship amongst the hashboard and the Command board. Test the cable to view when there is an open circuit.
Check with the voltage benefit array explained via the sign pattern. When the measurement encounters a sizable deviation of the voltage price, it might be in contrast Together with the measured price of the adjacent group to determine.
