Edit: can’t believe I didn’t describe the issue. The thermostat itself is just unresponsive, blank screen. It’s not receiving power. It doesn’t appear to be a model with batteries btw, as I see no way to open any of the back portion of it.

Edit 2Am I an idiot? I don’t see a battery compartment anywhere:

Also I can see from the voltmeter that the C-R labeled wiring is receiving roughly the required voltage. https://ibb.co/Yfh5W1C

Heading to the hardware store to buy a multimeter.

I threw some circuit breakers in the house last night while investigating a light, but they all should’ve just been in the kitchen.

The user manual says nothing of real value to me. I’ve thrown the AC, heater, and other circuit breakers. Anything I can do other than check with a multimeter and then call a technician?

    One last quick question: I just threw my breakers labeled Furnace and AC, and the lines are still hot. What else could it be receiving power from?

      that's odd. power should be coming from your furnace. They sell adapter kits that use a power outlet to inject power where you don't have a C wire from the furnace, but those are pretty obvious and usually located near the thermostat on the wall. Maybe your breakers are mislabeled?
