Hey Jason. Sorry for the late reply. Debugging a problem like this can be pretty involved. There are so many things that could have happened and theres no one approach to figure out what is wrong. It could just be broken. You already did the first step which is to undo the bends you already did and look for shorts. AT this point I enthusiastically encourage you to move on to the next project. Find another casio and make sure your process is organized and the work is clean. You can spend a lot of time trying to fix a dead keyboard. You are probably better off building a new one.
