How can I fix it for antminer L7 Temprature Read Error
As you can see in the picture, a temperature sensor reading error occurs.
The soldering condition of the temperature sensor and surrounding resistors was checked.
It was also confirmed that input via PIC worked well.
Which areas should be checked additionally?
Parts already confirmed: Temperature sensor (PT1, PT2), I2C Data Bus Pull-up resistance, PIC I2C input, temperature sensor A0/1/2 PullUP/PullDown resistance.
