2, maintenance by situation. First, the power supply does not start, plug the power supply, the large capacitor has 300V voltage, unplug the power supply and measure the large capacitor 2 end or 300V voltage does not drop. After discharging the capacitor, replace the starting resistor. The starting resistance is in the power input part, the resistance value is 150K, the power is 2W, the second is the flashing light, the circuit board is welded again, and the machine is tested again, if it is still flashing, please check the sampling resistance of the output end. 0.1 euro. 3W power.
3, check the power socket:First, make sure the charger is properly plugged into the power outlet and check that the outlet is working properly.

4, the position of the mobile phone is not correct. The phone can be placed correctly according to the direction prompt on the wireless charging board, and the owner can operate it by himself. There are foreign bodies between the mobile phone and the charging board, and the foreign bodies on the wireless charging panel and the back of the mobile phone need to be cleaned, and the owner can operate by himself. Wireless charging protocols are not compatible. Use a device that is compatible with the Qi wireless charging protocolLine charging is fine.
The main reasons for this kind of failure are: overvoltage and overcurrent protection circuit open and short circuit; The vibration circuit does not work; Power overload, rectifier diode breakdown in high-frequency rectifier filter circuit: filter capacitor leakage, etc. The fault of the charging indicator is divided into two types: the charging system can be charged and not charged. Method 1: When the ignition switch is turned on, the charging indicator is not bright, and the generator can generate electricity again after the engine starts, indicating that the generator charging system is positiveConstant.
May be the motherboard has parts damaged, need to be repaired. Wireless charger is not easy to break, just related to his production process.
