Remove wires at tstat Turn switch for furnace off than on.
touch the red wire to the white to simulate a call for heat.
Or Touhc red green and yellow to simulate a call for cool.
If that works get a new thermostat.

Sounds to me like you have a low voltage short. If the stat had no display until you installed the battery means there was no voltage for the stat to work. Putting the battery in proves the stat works, no motors turning on probably leads to a blown low voltage fuse generally a blade fuse on circuit board in indoor unit. Good Luck

SOURCE: How do I
There is a seam around the edge of the Thermostat , a small screwdriver or butter knife should do the trick , if not then its mounted to a plate on the wall that has 4 corners basically...Gently squeeze the bottom and pull the bottom out , they are pretty sturdy and you shouldn't have a problem,...the wall plate may flex a little while doing this
