I took the batteries out of my honeywell thermostat RTH230B and now it does not go on

Put new batterys back in. OR check to be sure you installed the batterys in the correct direction.

On most items the batteries are there to:

A: For the backlight
B: To Backup user settings.

Remove batteries, cut power to system for several minutes so any erroneous data is flushed. Install batteries, power back up.
After confirming item is operational, reprogram.
