Mend Honeywell Lost Changed Batteries

Why has my Honeywell CM921 thermostat lost patches of its display?

My Honeywell CM921 thermostat has lost much of its display and can no longer be programmed. I have changed the batteries (new but bought some time ago) which didn't work. I intend buying fresh batteries. Any other suggestions.
