1) Power supply system failure: Check whether the power supply of the power adapter is normal and whether the AC power supply voltage is between 100V and 240V;
2) If other indicators are on, the internal MCU is faulty. Once the MCU fails, the user can only contact Yuanwanggu Company to discuss maintenance matters.
