Hi @Parry,
Thank you for posting in the community. I'm sorry to hear that your Nest Hub has gone blank, preventing you from seeing the QR code or setup code, and you're unable to set it up again even after a factory reset. This is especially concerning, as this has now happened with a second device, both out of warranty.
Given the persistent nature of this issue across multiple devices, our specialized team would like to know more about your case and recommend a solution. We would appreciate it if you would fill out this form to contact us and find an answer:
Feel free to reply to this post when you complete it. We are happy to help you.
Best regards,
Kevin
