When the relationship is Okay, you'll be able to carry out a PT2 check on the board to find out if it might go the test. If it can be analyzed, it is basically particular that it is a difficulty Using the Handle board. If it can't be examined, use a similar repair strategy as PT2 to repair it.
Get the best mining general performance out of your respective Antminer S19 by using the right software program. Be a part of minerstat and find the best suited software package in your setup.
3V electric power source is standard; Check out the welding quality from the chip which connects sensor and the smaller warmth sink. The deformation of large heat sink substance will cause weak heat dissipation with the chip and affect the temperature distinction. Figure five-13 3. Phenomenon: Single board detection chip isn't comprehensive (PT1/PT2 stations)
Insufficient number of chips: If the quantity of chips is inadequate, you can confer with PT2 for tests and repair.
8V, 1.8V patch filter capacitors (evaluate the resistance of your patch filter capacitors associated with the back and front from the PCBA)
If your temperature exceeds this temperature, the miner will alarm and cannot get the job done Usually. Frequently, you may Verify if the h2o outlet temperature exceeds 65 levels, and thermal conductive gel may also trigger temperature abnormalities.
Check out the equipment to ensure that the exam fixture can perform commonly. Determine the parameters of the upkeep station check program, the Edition of the test jig, and other similar parameters.
two. Soon after there won't be any troubles in program tests (limited circuit detection in regimen screening is mostly essential to steer clear of burning the chip or other products due to shorter circuit when electrical power is on), the examination fixture can be used to detect the chip, plus the positioning is often determined determined by the test fixture detection results.
Keep on to research with dichotomy till the problematic chip is located. Assuming that there's a dilemma With all the Nth chip, once the 1V8 and RO amongst the N-1th and Nth chips are small-circuited, N-one chips are available, but in the event the 1V8 and RO concerning the Nth and N+1th chips are limited circuited, all the chip can't be located.
Other serps affiliate your ad-click on conduct by using a profile on you, which may be utilized later to target adverts for you on that online search engine or all-around the web.
Check out whether or not the 4 resistors of R24~R27 are welding abnormally and Verify whether or not the welding of PIN2, three of U3 is typical.
Our replacement hashboards are not only refurbished, These are upgraded to guarantee greater functionality and trustworthiness than the initial. Every hashboard goes via a rigorous recovery approach which makes them far more dependable than new kinds straight in the producer.
c) Liquid crystal display Show ASIC75: (Reporting 75), it means that the hash board can detect seventy six chips at 115200 baud level, but only seventy five chips are located at 12M baud fee, and one particular chip could not find at 12M baud charge; Repair method: Contact Here Utilizing the dichotomy approach, brief-circuit the 1V8 test issue as well as the RO check issue amongst the 38th and 39th chips with the shorter-circuit probe.
Continue on to investigate with dichotomy till the problematic chip is uncovered. Assuming that there is a dilemma Together with the Nth chip, when the 1V8 and RO involving the N-1th and Nth chips are brief-circuited, N-1 chips are available, but in the event the 1V8 and RO in between the Nth and N+1th chips are shorter circuited, your entire chip can not be discovered.
