Hook up a tv/monitor and look for signs of life. If there are none, remove the m2 drive and check again. If you now see some messages displayed, the m2 is faulty. However! It’s a nucleus! I’d contact your supplier for support.
I’m sorry you’re down! I second the motion from @mikeb to try connecting it to a monitor or TV via HDMI. It will let us know if it’s truly dead if nothing is displayed on the screen.
If you get nothing there may be an issue with the motherboard. It’s possible to reset the CMOS but the process is very involved and will include using thermal tape to resecure the processor. Let me know if you want to go this route and I will get you some steps/directions.
I’m not aware about computing but I’m ready to learn if it’s not to difficult (I have no PC, but only an iMac and I’m ready to follow your steps/directions)
If possible I prefer to have my unit repaired by a professionnal.
I’ve called French distributor, he don’t want to repair a Nucleus I didn’t buy from him; do you know someone else in France to fix the Nucleus?.
I’ve called three French dealers. None of them want to fix or help me to fix it as my Nucleus was bought used and abroad.This is not a very good image for Roon products in France.
Probably I’ll try to do it by myself.
I need your help for that. (It seems it could be a motherboard problem. Where is it possible to buy a new one?)
Thanks for your help
I understand the frustration and it’s certainly not a pleasant experience.
There are risks involved when buying 2nd hand and abroad. You probably did it because it was a good deal, but that implies situations like these when things go wrong. Something about having cakes and eating them…
I’m sure that one way or the other, the unit can get repaired. Be it via Roon, or a computer repair shop that can help out. You can probably do it urself too. It’s a fairly simple procedure.
I think the first thing to check is to see what’s gone wrong: is it the M.2 SSD or is it a problem with the motherboard.
To do that, follow @mikeb’s advice that he posted earlier in this thread: remove the M.2 SSD and see if you get messages displayed on the TV/monitor.
If you do, then the M.2 is the problem. If you don’t, then there’s an issue with the motherboard. In that case, the next thing to try would be a CMOS reset, and @Wes will give you instructions for this.
