in 01/03 I replaced my thermostat with a honeywell ct3611r4450. I have a/c with a heatpump and aux heat at the air handling unit. the thermostat worked fine until 07/03. I had the thermostat set to cool for a week then turned it off. I went to turn the thermostat back on to cool and the display was blank. Being it was a new thermostat I checked the power output at the step down transformer at the air handling unit 27vac. So I replaced the thermostate and base with a new honeywell ct3611r4455. As I was pluging the display into the base the display blinked on and off as if a loose connection then stopped. as I was starting to program the thermostat it went blank. I called Honeywell and they stated that there is a power problem between "c" and "r" but there is power. Any ideas on what to look for and how to resolve the issue.
