Verify that your thermostat faceplate mounts properly against the base if the screen is off and not lit. There are two small screws at the bottom of the thermostat which you can loosen. This allows you to remove the face plate from the thermostat.

Once you have taken off the face, press the reset button located on the back of the face. Then, remount it to the back of the thermostat making sure the 8 gold pins tightly fit into their counterparts.
