Have you tried pressing the reset button through the hole on the back of the calculator? If yes or this does not work, the next most radical procedure is pressing ON plus A plus F at the same time to completely reset the memory. Warning - you will lose all programs and data on the calculator! If these actions don't produce positive results, it sounds like you have a may have a stuck key. Search for posts from Randy Sloyer and/or Han for discussion of key and other repair.
