Why is my Honeywell T7351 Thermostat display not working?

If the Honeywell Thermostat display is not working, it may not be getting power. Ensure the X terminal is connected to the system transformer. Also, check for 24 Vac between the X and RH or RC terminals. If 24 Vac is missing: * Check if the circuit breaker is tripped and reset it if needed. * Check if the system fuse is blown and replace it if necessary. * Ensure the HVAC equipment power switch is in the On position. * Inspect the wiring between the thermostat and HVAC equipment, replacing broken wires and tightening loose connections. If 24 Vac is present, continue troubleshooting.
