Common faults of the whole machine and troubleshooting steps1. Power consumption comparison table of the whole machine:

Schematic diagram of the front and back of the control panel:

2. Phenomenon: The power of the whole machine cannot reach the power consumption in the above power consumption comparison table and cannot log in to the Web backendSolution:Step 1: Check whether the two blue LEDs on the control board are on (position number: D1, D6)

Step 2:
Check if the voltages of TP3, TP4, TP5, and TP6 on the control board are:
TP3 = 1.0V, TP4 = 1.8V, TP5 = 1.5V, TP6 = 3.3V

Step 3:
If the above voltages are normal, and one of the blue LED lights (position number: D6) is on, and the current is about 0.08~0.1A, it means that the system has not started.
You need to check SOC, DDR, and FLASH.
Measure the voltage on both sides of the R22 resistor, as shown in the figure below.
When the voltage on both sides is about 1.5V, it may be that the program in the FLASH is abnormal or the FLASH is damaged;
When the measured voltage is about 0.69V, it means that the FLASH and SOC are normal.
If you cannot enter the system at this time, there is a high probability that the DDR is abnormal.
Exceeding this current means that there is a short-circuited device in the circuit.
