Cause: The power supply voltage is unstable
< br >
The instability of the power supply voltage will also cause the lamp to suddenly go out, you can check whether the power supply voltage is normal with the current pen after the light is turned off.
< br >
If the output voltage of the power supply is normal, but the lamp still automatically turns off, the voltage problem is excluded. If there is no output voltage or the voltage becomes significantly smaller after the lamp is turned off, it is the problem of the power supply voltage, and you need to wait for the voltage to return to normal, or ask a professional to replace and repair.
The first possibility is that the pilot light is broken.
The second possibility is that the data cable or charger is damaged.
The third possibility is that the contact of the charging port is not good. The specific solution to the millet phone charging indicator light is off for a while:
The first step is to check whether the parts of the charger and data cable are still intact.
The second step is to plug the data cable more tightly.
Step three, try a different cable.
