instructions might, or might not, be on there

I've checked that link, it's not there. One of my sensor is dead and I'm ready to fix it as well. I have a midi controller to work around it but it's not the same as hitting the pad. Anyone changed there sensors for the 2k before? If so, please help us out. Peace.
