I ended up taking apart the thing, but I didn't know what to do at first so I just started unscrewing until enough of the right pieces fell off. I got to the rubber contact strip and air-cannistered it. That seems to have done the trick, I didn't see much dirt on or around the rubber contacts. I took some pictures as well http://imgur.com/a/Lqk1J

Hi, I didn't know where else to go for help. I have a px-720, one of the keys (a high acts wacky compared to every other key. The touch response seems to be funky on this one key. When I press it, it is louder than every other key. This was a recent development; how do I fix this? What do I need to take apart? Thank you.
