One more thing to try: remove batteries, also remove the backup coin 
cell, leave it alone for some hours -- 24, say -- and then try again. 
Also, once the batteries are removed, try pressing all the keys, 
including the arrows and reset pinhole, several times.

This probably won't work, but it can't hurt, and I've heard of cases 
where it did work (not with your precise symptoms, of course).
