My thermostat for my heating and air just completely went blank. It's digital any ideas why?

It depends is your t-stat battery powered if it is change the batteries, if not it is powered by a 24vac transformer, and it could have went bad, or the t-stat is dead.

Also a wire could have came loose either the red 24vac power wire to the transformer or the common black wire.

Also the 3 amp fuse on the furnaces control board may have blown for some reason.

You need a volt meter and start checking around but if you don't know how to use it, you had better call in the professionals.
