my k3 used to work fine and then i didn't play it for awhile. now i 
decided it was going to get a job in a band of mine and it has some 
serious problems. First of all the lcd screen is out so i can't 
prgram anything. i don't know hwhat that could be. second one of my 
keys has quit working, and also i cna't switch between my little rc-2 
card and the internal card. it's stuck on the internal patches. so if 
anyone can help me remedy any of these problems i would appreciate 
it. thanks. -t
