Power outage screwed up some parts but not others
There is a pinhole reset button on the echo. Try to press this with a pin or small pen when plugged in
After I dropped my echo I had the same issues. I took the echo apart, all the way down to the bare parts, then put her back together again making sure the ribbon connectors were nice and tight, and she came back to life- lit right up.
After a power failure, I reset with the pin hole in the bottom first. Then I had to set up my Echo as a "new device", and then have her discover the lights etc again. All back on line now.
Blue light ring keeps spinning,nothing else works
