Quick answer
Is the thermostat or the HVAC equipment causing the problem?
A blank screen, wrong temperature, short cycling, or failed call for cooling can come from thermostat power, batteries, wiring, sensors, configuration, condensate safety controls, equipment faults, or communication errors. Diagnosis should verify the control signal and the HVAC response together. Replacing the thermostat without testing the system can leave the actual fault unresolved.
