SOURCE: flashing battery symbol
I had this same problem today. I called Honeywell and they said the flashing broken battery symbol may mean low batteries, or it may mean the battery type is incorrect. They recommend only non-rechargeable alkaline batteries. I was using rechargeable NiMH batteries. Even though they were fully charged, I had the flashing battery symbol and the thermostat relay would not work. I replaced with alkaline, the flashing battery indicator went out, the thermostat works again.
Odd that it worked for 3 months on the rechargeables after first install. I did notice the broken battery symbol came on after the first few days, but I checked the battery charges and they were good, so I disregarded the symbol until the thermostat stopped working today. Apparently there is something about the NiMH performance characteristic that the thermostat doesn't like.

the cover pulls off if it has a green screen then most likely takes batteries if does not light up then no batteries with a small piece of insulated wire jump from green to red if indoor fan does not come on then transformer bad

Okay it seems that for some reason the battery change scrambled the brain of the t-stat... that happens...
To fix it you will now have to go into the "Installer Menu" and reset the paramenters of the t-stat.
If you have the Installe brochure then you can look in there and then set the tistat for "heat/cool" and also to "auto fan" and then to "auto changeover" These should get you back to cooling again...
No big problem, just a small programming issue...be patient and if you do not have you book don't worry... you can look it up here...this tip tells you where and how to find any of the Honeywell t-stat manuals.
