Hi
my above sharp cash register was working ok when i left it last night. This morning the display is on showing 0.00 but none of the keys respond when i touch them. only the till roll key works. Any ideas I have only had it for 3 months from brand new. I have removed the batteries and gone through the set up instructions again still no joy.

I've had this before. It was main board failure. Take it back for warranty repair.
