Hello, Have you tried plugging it to a power supply from a different camera just to rule that out?
The warranty is 1 year from Google. But if it is close to that time they might still help you out.
Do any of the lights on the camera come on when you plug it in?
There is a good chance it has just become broken. I have a good number of these GEN 1 cams and they seem to last between 3-6 years. I have had a few go bad and I just buy replacements used from eBay sellers and I have had good luck with that. Sadly I can't recommend the newer cameras (for now). They only work in the Google Home app and you would have to bounce back and forth from the NEST APP for the older cams and the Goggle Home app for the newer cameras which is a pain.
