Verify 24 volts at the low voltage transformer inside the air handler. If it is OK, jump out the red/green and yellow thermostat wires. If everything comes on, replace the thermostat.

controllers more than likely on a memory lockout... kill the power and take the batteries out of it... leave it for 60 seconds and try again... unfortunately you are probably going to have to replace the controller, sorry
