Sometimes these screens can just die, offering the "opportunity" to buy a newer technology! First thing to do is a full reset - check the manual to find out how, but it's going to be something like a little button, maybe inside the battery compartment, look for a small hole that might take a paper clip. Failing that, take it back to the store, especially if it's relatively new.
