Hello @Jaroslaw_Karelus
Thanks for the report, and I’m sorry to hear you’ve hit some hardware issues with your Nucleus. The best next step here is to get in touch with our RMA department directly, as they’re in charge of all hardware-related Nucleus issues. To do so, open the Typeform link below and select ‘Other’ followed by 'This issue is related to a physical component".

They’ll help get you sorted out moving forward. Thanks! 
I bought a Nucleus in Poland and no distributor wants to take it for repair
No need to go through a local distributor — our RMA department handles repairs and replacements directly, regardless of where you purchased the Nucleus or where you are located. Please reach out to them directly via the Typeform link I shared, and they will take care of you from there.
Thank you!
