Find the transformer and see if its getting power or putting out power... Otherwise you are going to have to hire a pro if you can't find it.

Check batteries in the stat if so equipted. Next, check breaker to air handler or furnace. Also check fuse in ssu switch box on the side of the unit if so equipted. If there is no power to the furnace or air handler, the thermostat will not work (if your stat doesn't have batteries, or the batteries are dead). Let us know what you find.
