I took apart a Sharp EL-1197P calculator and cleaned contacts with 91% isopropyl alcohol. When I reassembled it and plugged it back in the power switch was set to off but still turned on. I flipped it back and forth still nothing. Please help!

MY calculator won't turn off except after being left alone for a long period of time and the buttons aren't responding. Also it only displays 0=. and I've even tried restarting it many times.
