Same problem here. 2 years faithful service in my front yard. Occasionally it had a hiccup and I’d do a hard reset. One day it just completely died. I cracked it open and found an epoxy sealed power supply with wire crimped connectors that had completely corroded. I cut out the bad connections and soldered everything but no luck. It was clearly a water intrusion issue. I then smashed the power supply with a hammer and put the camera (without lights) back on the wall with a new EXTERNAL power supply (no replacement supply available anywhere).
