Lots of recent threads on this topic
The presentation wanders a lot.
But the messages are simple: 1) equipment failure happens but is rare. 2) More often it is a connection problem, so start there. 3) Break things down by eliminating possibilities one at a time until you are looking at just one thing and diagnose that. 4) Sufficient power at the device? Corrosion and resistance impacts it. Poor connections impacts it.
