    Lumin L1 Blue light flickering, not found in Lumin application

    We had thunder storms today and I powered off all my audio equipment. After powering everything back on the Lumin L1 just has a fast flickering blue LED and no other LEDs are on. The Lumin app doesn’t see the L1. Please don’t tell me I need to reformat.

    It is the 5TB model.

    Please power cycle the L1. Then check that the network port LED in the L1 flashes, and the network port LED at the switch / router also flashes for the L1 network connection.

    Re: Lumin L1 Blue light flickering, not found in Lumin application

    I tried the power cycle and confirmed I had an internet connection at the router and at the L1. I plugged the L1 into my iMac via the USB cord and I get the same behavior, a constant blinking blue light and blinking LED lights on the LAN port (no LAN connection, just USB cord to iMac).

    The iMac never recognizes the L1 is connected via USB. I tried two different USB 3.0 cords.

    i also swapped the HDD in the L1 as it seemed the HDD in the L1 was doing a lot of searching. No change flashing blue light on front button.

    So, with either network connection or USB connection, the L1 behaves the same and blinks blue quickly?

    Any red LED?

    Any green LED?

    Yes whether hooked up via USB or to the LAN the front Red and Green LEDs never light up. Only the Blue LED flashes rapidly.

    I'm sorry but this sounds like it requires repair.

    Once again, after communicating with Peter Lie via email he solved my problem by suggesting I try a different 12V wall wart. Sure enough that fixed the problem. I am a devoted, happy Lumin customer and I know of no other audio company that provides such a high level of personalized service like Lumin.

    Thanks Peter for going above and beyond (again)!
