UPDATE- Confirmed that my suspicion about this being caused by the heat proved to not be the case and verified by those who live where it is REALLY HOT.
Now- the camera will not intialize- just come up with warning to watch the suroundings, -or- a blue screen both of which are followed by a pop up message box that the camera is unavailable.
Several YouTube videos with trouble shooting tips that I used to narrow this problem to either the camera or a connection.
There is an excellent YouTube video on removing and replacing that I will follow once I get the replacement cam.
Thanx for everyone's input. I will report back with my anticipated success once the daytime temps drop below 110.s
