If the indicator light does not light up, it indicates an open circuit fault in the hardware. Check the wear of the gold finger, whether the abrasion is damaged, and whether the PCB circuit is open. Identify the faulty pin based on the numerical indication of the indicator light, and then use a multimeter to identify the specific cause of the fault.
