Hello Ef3,
Thanks for visiting the Community.
Sorry to hear that you're having issues with your Google Nest Hub (2nd generation) screen. I'd love to help. A few questions: when did the issue start? When and where did you purchase your device?
Let's go ahead and reset your Nest Hub (2nd generation) by pressing and holding both volume buttons together at the back of the Nest Hub for about 10 seconds. You'll hear your Google Assistant confirm that it's resetting the Nest Hub.
Let me know how it goes.
Cheers,
Muddi
