    Lumin d2 display issues

    My D2 is having issues with the display. It doesn't always turn on once powered up. It takes turning on and off the power numerous times before it ( the display) finally comes on. There is nothing wrong with the power cord as the Ethernet port shows it is receiving a signal (blinking green light shows that the Ethernet port is working) but yet the display isn't on. In settings I have the display set to never turn off. Any thoughts as to whats wrong?

    First time I read something about display problem or problems with D2.

    Hope you can solve it soon.

    Re: Lumin d2 display issues

    Have you tried a reset by taking a pin and putting it in the hole labeled reset on the back panel? Iím not sure itíll fix your problem but thatís what I would do if it were mine.

    Re: Lumin d2 display issues

    Even if the display is not showing anything, can Lumin app see the D2 on network and play normally 30 seconds after it boots up?

    Are you using a third party LPS?

    The LUMIN app doesnít see the D2 when this happens. I am not using a third party LPS.

    Re: Lumin d2 display issues

    Having the Lumin D2 for over a year I noticed same issue with display.
    (I had connected th D2 to an Sbooster wich gave to my ears better performance)
    ' Playin' with the on and off switch from the Sbooster solved the display problem now and then.
    Recently I ordered the remote control (not so cheap) and switched the Lumin on and off by the remote.That worked fine for 1 to 2 months but then the same display issue came back.
    My simple guess is that there maybe some hardware weakness in the product.
    Fortunately I also own an Auralic so I can
    still stream music. (but I liked the sound signature of the D2 a bit more)

    Re: Lumin d2 display issues

    Well my D1 in the other room had a similar problem and after getting with Peter it turned out it was the power supply that was going bad. Ordered a similar spec'd supply, problem resolved. It was intermittent flaky until the Lumin would not turn on at all.

    Re: Lumin d2 display issues

    I have a Lumin D1 .. same issue. I did swap to a Sbooster Power supply. It didnít resolve the issue. I looked at the specs on the original power brick and itís a 4 Amp power supply.. I donít know if the Sbooster has enough current output

    Re: Lumin d2 display issues

    For troubleshooting D1, please try another SMPS like the factory 12V 4A power supply, but not an LPS. An alternative compatible brand is Meanwell 12V 5.5mm x 2.1mm.

    Hi folks,
    I am having a similar problem. The app on my iPhone or iPad wonít recognize the Lumin D2 and the display wonít come on. The Ethernet lights blink, the fuse is good, the power cord is good but the Lumin display is not working. I havenít had any problems prior to today and all of a sudden I get nothing.
    In the app I cannot access my Qobuz account either if that might be a clue? I tried to contact wklie for some assistance but Iím a new member and donít have permission yet to do pmís yet.
    If you folks came up with a solution I would love to know how you fixed it. Thanks for any advice!

    Mine was eventually repaired by the US IMPORTER. I donít recall what specifically was replaced/repaired, but they had to put in a new board. I suggest you contact them directly. I donít have their number, but I am sure someone here has it.

    Thanks MRJAZZ!
    I was hoping it was something simple I could fix. Iíve got my fingers crossed! Kind of a bummer if it requires outside service as Iím out of warranty.

    Re: Lumin d2 display issues

    The service center in California repaired my D2 in about a week. Works like new again. I was out of warranty and while it wasnít exactly cheap, the repair was much cheaper than a new streamer/dac.

    Add another Canadian resident to the list. My D2 intermittently does not want to boot. Hoping to find a solution before it dies.

    Re: Lumin d2 display issues

    Lumin distributor tells me it's either the PS or main board. Main board is $500USD to replace.

    Does anyone know which one has failed in this instance?

    Re: Lumin d2 display issues

    Dear All

    I have read the forum regarding Lumin d2 boot issue. Unfortunately i have a similar problem.
    Everything original, power cord and fuse is ok, and yesterday this was worked perfectly.
    But today doesnít working, the display dark and blank, the reset button doesnít working The player not found by the application.

    I hope you know any tricks or solutions before I call the service. Iím afraid that the service will be very expensive for me.

    Thank you in advance for your support!

    I was very lucky. I had the same problem and sent it in for service. Lumin was very good to me and only charged a minimal fee to fix mine.

    Hi Peter

    I am also experiencing the same problem with my Lumin D2, I switched off and on the power several times, and it still doesn't come back up alive. Switched the power cord as well, still the same. I live in Canada.

    Thanks

    Does the D2 & U2 Mini share the same power supply? Thinking of getting the U2 Mini but now abit scared after reading this thread.
