Reply to VCI-100 Tempo Fader problems

I recently bought some chroma caps from this website to change up the look of my VCI-100. Well, they look great, except I believe I might have pulled too hard or something on the left tempo fader. It doesn't respond at all when I push it up to slow down the song, and is pretty unstable when trying to speed it up. I've found that if I move it left and right, the tempo changes dramatically, literally jumping back and forth several BPMs. Obviously, this is a pretty big problem.

Anyone here ever have any issues with the faders on the VCI-100? Any suggestions on how to fix it without the risk of breaking it even more?
