Powerless After-Professional Presence

[Rescalante1957]

My new Nest is stuck on error message e73 (no power to Rc wire detected). Professional checked Rc wire and power is detected. I'm stuck. Where do I go for a replacement? Is that my only option? Day 3 with no AC or Heat.

Is this a newly installed Nest or one that was working previously?

Do you have a picture of the original thermostat's wiring? if yes, then post it here
