Nucleus+ won’t boot if connected to HDMI

So my Nucleus+ Rev B has this problem. If i disconnected the HDMI it will boot perfectly then i can connect the HDMI again and it works. But if i reboot it with the HDMI connected to my TV or Marantz it wont boot up. I read some other people had similar issues and fixed it with a BIOS update… but i cannot find any info on how to update it. I bought my Nucleus in Thailand from a seller almost 2 years ago i don’t think it was an official seller. I’d rather do the update my self.

Please help me. Thank you

Hello @mauro_sciaccaluga ,

Thanks for the report. When this issue happens, is there anything being displayed on the HDMI output of the TV? Can you please use these instructions to manually access your Nucleus RoonServer logs, upload a set to the below link and let us know once uploaded? Thanks!

Hello,

If the HDMI is connected before I turn on the Nucleus, it won’t boot up at all, and nothing is displayed on the TV. Also, it won’t show up on my local network. The only way is to disconnect the HDMI from the Nucleus, which will boot up perfectly. Anyway, I will look into the log, but I suspect there will be no log of this event since the machine never booted up when connected to the HDMI.

Why no reply from Support?

I suspect @noris is waiting for your logs - it’s not clear whether you’ve sent any? Your point about the logs not being able to reveal anything may well be valid, but Roon Labs will still want to investigate them.

BTW, have you tried using a different HDMI cable?

Yes, I sent the logs to them a long time ago using the link provided. And yes, I have tried different HDMIs and TVs.

Can you post a link to this information? I don’t recall these particular posts, only that it is possible to disable the HDMI in the BIOS settings. Thanks.

It would be nice to be able to access the BIOS, but since it won’t boot with the HDMI connected to a TV, I can’t get into the BIOS as well.

Hi @mauro_sciaccaluga,

Unfortunately we’re not seeing any logs sent on our end. Could you please resend them over to our File Uploader?

This is a tricky situation indeed. What happens if you hold F2 during the reboot process, and quickly plug the HDMI cable back in quickly after the Nucleus is powering up?

Right now I am away from home for 3 months so I won’t be able to send the logs again until September.

No problem @mauro_sciaccaluga, we’ll be here when you’re ready to pick things back up. :+1:
