If the digital thermostat shows nothing, and there are not penlight (AAA) batteries under the cover, then the circuit is not getting power. Check the fuses on the converter, to make sure 12VDC is leaving the converter for all the circuits.
BTW, when you ask for help, you will get more specific answers if you tell people what make/model of camper you have.
