My ST1000 stopped working, after my battery died. I changed the battery, the compass on the pilot works, but there is no movement. It just blinks "1000"

Hi Gena!

This sounds very much to me as if the power supply connection is not as robust as it needs to be. We have an ST2000+ and find that if there is even a small amount of corrosion at the battery connections or even on the socket where the unit plugs into, we experience exactly the same symptoms you're referring to. Carefully check and clean all of these connections and spray a liberal amount of silicone spray or Fluid Film (my personal weapon of choice) on every electrical connection and see if this gives you any joy.

Hope this is of help to you.
