Line of keys not working.
I've had my calculator for years and use it frequently. Today, an area of keys - specifically "0", "1", "4", "7", ",", "sin", "apps", "x^2", "(", ")" stopped working. All other keys work fine. I've tried restarting, system reset, and changing batteries. I don't know if it's possible water damage (I have cats) or something else.
