Door bell pro blinking white

Door bell pro has had some fix from ring??? Didn’t know it wasn’t working (cos it was). But now it’s not. Showing blinking white light, as if firmware update for the last 3 days. Also says could be low power. So ordered new transformer to check. Still doing the same! Doesn’t reset or rejoin Wi-Fi if you take cover off and press the button on the side. Light won’t spin to reconnect Anyone had anything similar, cos it’s a pain in the arse Thanks, mark
