How to solve the problem that the energy storage power supply lighting light can not be lit and no SOS function?

If the energy storage power supply lighting does not light up, this could be due to a faulty lighting switch, damaged lighting, or a faulty lighting power supply circuit. If your power supply has the following problems, please follow the steps in this article to troubleshoot and solve the lighting problem.

Phenomenon: Lighting does not turn on, no SOS function 

       

Step 1: Check the illuminator switch

Check if the illuminator key switch is stuck. A normal key can be pressed flexibly and is not stuck.

Step 2: Check the energy storage display

Press the power display switch to confirm that the stored energy power supply is fully charged. Running out of power will cause the lights to fail to illuminate.

If the key switch is normal and the power is sufficient, but the light still can't be lit, then it is an internal fault.
