Check The placement from the temperature sensor. The temperature sensor is all Found within the back of the PCB, when the resistance is located around the entrance in the PCB.
Irregular temperature: Normally, the temperature is high. The most PCB temperature established by our checking procedure can not exceed ninety℃.
Solder paste column M705, flux, board washing water with complete Alcoholic beverages; board washing drinking water is employed to wash up the solder residue right after repair; thermal gel (specification: Fujipoly SPG-30B) is accustomed to smear the surface area from the chip right after repair ; ball-planting steel mesh, solder absorption wire, solder ball (the ball diameter is usually recommended to be 0.
a) LCD Screen ASICNG: if (0), first measure the entire voltage with the measuring domain along with the boost circuit 20V is typical, after which you can utilize the quick circuit probe to small-circuit the RO test stage and also the 1V8 test issue concerning the first and the next chip, then operate the program to locate the chip. Check out the serial port log, if 0 chip remains observed at this time, It will likely be certainly one of the following situations: a-1) Use a multimeter to evaluate whether or not the voltages at the 1V8 and 0V8 take a look at points are one.8V or 0.8V. Otherwise, it indicates that the 1.8V or 0.8V LDO circuit of this area is irregular, or the two ASIC chips of the area is just not soldered effectively; most conditions of this phenomenon are caused by small circuits of 0.8V, 1.8V patch filter capacitors (measure the resistance on the patch filter capacitors linked to the back and front from the PCBA). a-2) Check out whether or not the circuits of U2, U3 and U4 are abnormal, like resistance welding, and many others. a-3) Measure the resistance of R232 or R233 with a multimeter to check if it is inside of one ohms and also the looking through won't leap randomly. If not, please change these two resistors. a-4) Check out if the pins of the primary chip are soldered very well (it absolutely was found throughout repair the pins are tinned observing from your side, though the pins are usually not stained with tin in the least in the event the chip is eradicated). b) If a person chip are available in phase a), it suggests that the primary chip as well as the previous circuit are fantastic. Use a similar process to check the subsequent chips. Such as, limited-circuit the 1V8 take a look at stage as well as RO take a look at stage concerning the 38th and 39th chips. Should the log can find 38 chips, the 1st 38 chips have no dilemma; if you continue to discover 0 chips, Check out the 1V8 1st; if it's standard, it means that there is a dilemma Together with the chips following 38. Continue on to research with dichotomy right until the problematic chip is discovered. Assuming that there is a issue with the Nth chip, in the event the 1V8 and RO involving the N-1th and Nth chips are quick-circuited, N-1 chips can be found, but once the 1V8 and RO amongst the Nth and N+1th chips are small circuited, all the chip can not be discovered.

In case the miner continue to loses hashrate, lessen the frequency and also other disorders remain unchanged. Enable the miner mine to determine if it's going to get rid of hashrate and if the hash board will hit X. If it nonetheless hits X in dropping hashrate, then get rid of the heat sink of your hashboard for mining and wait for the hashrate to fall.
The next fault illustrations are from Antminer 19 collection mining equipment, other Antminer models are for reference only.
(one) Unexpected ability failure in the course of OTP or time of under 30s will induce the Manage board to are unsuccessful to open the OTP purpose.
At that point, Microsoft Marketing will make use of your whole IP deal with and user-agent string to make sure that it could possibly appropriately process the advertisement click on and charge the advertiser.
(two) U1 cannot be made use of on other number of types In case the OTP perform is enabled on the control board.
① For starters, visually inspect the hash board to determine when there is any deformation or burning in the PCB. When there is any phenomenon, it needs to be addressed to start with.
minerstat isn't just Yet another calculator - It can be a robust mining System that supports your copyright journey. Raise your profits, conserve useful time, and increase efficiency with our suite of premium functions:
Should the serial port stops long-distance managing after the short-circuit, it means the main chip is OK. As outlined by this technique, find the chip that still fails after a long-distance managing after a chip brief circuit. Commonly, it's due to a harmed chip, and you will replace it;
1. Pay attention to your operation method when replacing the chip. Immediately after replacing any extras, the PCB board shall have no evident deformation. Examine the substitution components and the encompassing sections for open up circuit and brief circuit difficulties.
