The blue LED indicates whether the device is on or off. If the device is working and the blue LED is not on, the LED may either be faulty or it has poor contact to the wire and/or to the printed circuit board. We will demonstrate the steps on getting to the blue LED from inside the device for replacement. Then, we will replace the blue LED.
