You may have a 24 volt supplied thermostat. You should go to your furnace or airhandler depending on where you live and get at the board inside that, on the board you should see a slot style fuse 3amp...pull that out and check it to see if it is burned out. If it is replace it as that will cause the thermostat to be blank and dead. CLICK HERE FOR A PIC of what you are looking for.
