Antminer L3+ hash board common problems and solutions

1. A certain hash board chip displays X, the number of chips is sufficient, the real-time hash rate is available, but the total hash rate is not enough;

Treatment method: send it to the nearest repair center for repair, or replace it with a new hash board.

2. A certain hash board chip displays X, the real-time hash rate is there, and the average hash rate is not enough;

Treatment method: send it to the nearest repair center for repair, or replace it with a new hash board.

3. The number of chips on a certain hash board is not enough, and there is no hash rate;

Treatment method: send it to the nearest repair center for repair, or replace it with a new hash board.

4. This miner's No.2 hash board has not been detected. The power has been cut off, the data cable has been re-plugged, but the No.2 hash board has not been detected. The ambient temperature is 25 degrees, the humidity is 50%, and the power supply is the official power supply ;

Treatment method: send it to the nearest repair center for repair, or replace it with a new hash board.

5. The chip status of a certain hash board all shows X, the actual hash rate is normal, the average hash rate is not enough, and the problem is still the same after power off for 5 minutes;

Treatment method: send it to the nearest repair center for repair, or replace it with a new hash board.

6. The number of chips on a certain hash board is not enough, but the display status is OK;

Treatment method: send it to the nearest repair center for repair, or replace it with a new hash board.

7. Individual chips of a certain hash board display X, and the real-time hash rate is normal;

Treatment method: power off for 5 minutes and then power on if it is still removed and repaired.

8. The hash rate is not enough; a certain hash board does not display the hash rate.

Treatment method: send it to the nearest repair center for repair, or replace it with a new hash board.

9. Some chips of the No.3 hash board cannot be recognized, and there is no hash rate

Treatment method: hash board No.3 has 6 ASIC chips that cannot be recognized by the control board, resulting in no hash rate for the hash board. Using a test fixture for single-board testing is recommended, and then repairing it according to the test results.

10. Single board test: not enough ASIC

Treatment method: 

1) Short-circuit the CO signal of the reported chip number to determine whether the chip number reported by the test fixture is correct.

2) Check the reported chip's five signal voltages and ground values.

3) If the 5 signal voltages and grounding values of the reported chip are normal, check the next chip (using the same method).
