Thread: Fuses in Lumins?

Anyone know the fuse size in psu on Lumin U1 ?

If you go inside, don't you void the warranty?

From the Lumin US distributor's website:

Lumin in the USA or Source Systems, Ltd, in the USA will not service product under warranty that have been opened by end-users, modified or altered. Modifying products immediately voids all warranties from Lumin in the USA.

IMPORTANT INFORMATION ON MODIFIED PRODUCTS!
Products modified (or “Modded”) by third party companies render Lumin products unserviceable by us.
Modifying products immediately voids all warranties from Lumin in the USA. More importantly, since we do not know what these “mods” are, how they affect other circuits within the Lumin product and most importantly, affect the timing and control functions within the product, we are not able, at any cost, to repair a modified Lumin product. Modified products should be returned to the modifier or upon prior approval, the overseas factory for service if and only if there is direct factory approval for such return.

How about for the D2? What type of fuse does it use? Out of curiosity does changing fuse make a big improvement on sound quality?

Hi peter,

any experience with after market fuses like SR blue, etc? Do that make a difference to the already great PS. FYI, I am using the X1 PS for my U1.

thanks

Thanks Phil. That’s very helpful.

Hi guys!
I am completely new here and i found this thread because i need your help. My Lumin D2 stops to respond in anything except two green ethernet lights in a back place (on a time to plug in the ethernet cable). i had the unit disconected for 6 months because of my seasonal job out of my home. Without power or something like that. I mean it was out of power plug, not only switch off.And in my first day i tried to switch on all my sound machines. All works perfect except Lumin. Its completely dead (except the two green kights). The reset hole dosnt work, the screen no respond in everything, its completely empty, and the machine ofcourse dosnt appear in any network in my home. I wonder if the fuse need change, or ....something on the power...?

Thanks Peter. The problem is i did not take it from my country because we don't have official sellers here (Athens, Greece). I bought it from Austria, from Smarthifi. I don't know exactly what is the best now? To send it in Austria or in Lumin factory in China?
I have the receipt but the warranty expired on February 2021 (my bad luck....but that's life!).

Hello alexandros,

maybe your unit only want to install a update (current Firmware 14.2). Make shure that it is connected to your network. Maybe you must activate the update option in the Lumin app.

Hello and thanks for the help. If you explain me how can i to install the firmware update i will follow your advice. The ethernet cable its connected but i cant see the unit profile in my home network or in Lumin app. The screen its not respond, remain black all the time. Any other way for the update?

Maybe you want to check your fuse. In my U1 mini it's next (integrated) to the power connector. It's a F2AL250V. You must pull out that sled. Then you see the fuse.

Thanks Carlo again!
How pull out the sled? I have the same case and power connector with yours. I tried with my fingers,its impossible. I tried with a knife inside the borders of the sled but i am afraid for broken something. I know you thing i am little bit ...stupid but believe me i tried. Except if there a special way to open the sled and i dont know this way.

I used a small screwdriver to pull out the slid.

The fuse sled can break very easily. The USA dealer was Zero help on finding a replacement. I was able to find one myself however.
I am now using the QSA red fuse and it is impressive in this unit.
