I wrecked my calculator yesterday in the morning with sink water when i was cleaning the outside with the cover on. i didn’t realize it was broken until i tried using it before a class in the afternoon. At that time, when i turned it on. the screen was showing the home screen, but there would be a wavy line moving from top to the bottom of the screen every few seconds. And when i tried turning it off it wouldn’t respond. At the time i didn’t have the screwdriver to take out the battery so i left it alone until after my class. When class was over, i checked the calculator and it was off. When i got home in the evening to take it apart and remove the battery, the inside seems dry. I didn’t see any rust or discoloration on the boards. The battery looks fine to me. After letting it dry further, i tried to connect the charger to test if it would turn on last night. After a few minutes of charging the calculator, i can hear a slight noise within the calculator when i press the ON button. The display didn’t show anything (black screen) and oddly, the other metal outlet opposite to the charging port started to heat up. So i disconnected the charging port. And this morning, after reading other online guides about electronics further, i removed the battery. Is there much i can do at this point to recover the calculator? I can’t tell if the display has problems, or the power connector, or other things. Are there ways to find out what’s wrong and to fix it?
