This is bizarre and can’t find any similar problem online about it. I have two VDB750 video doorbells. Both have been installed about a year and have worked fine until today. One of them, it seems, no longer lights up (the once-green ring, is now dark) and if you press the button it does not chime either outside or inside. However, the video is still working fully, live stream, etc. Therefore, I know it’s fully powered and connected to wifi.
The other VDB works perfectly as normal.
Any ideas??
