When I turned it it has a black screen, the entire screen is black and none of the keys do anything. I replaced the batteries.

I think your keys still work, but you need to adjust your contrast. To adjust the contrast by lightening the screen, press and release the "2nd" button and hold the down arrow. Reply back if this doesn't work. Hope this solution helps!

Maybe you need to adjust your contrast. Just hit the 2nd button, then hold up or down on the directional buttons to adjust. If that doesn't work, changing the batteries might.
