Reply to more problems with the vestax vci-100 jog wheel

for some reason, my right jog wheel is now getting stuck often. now what i cant figure out is why, because, its not the actual physical wheel that has restricted movement. it seems to be more of the receiver because when i try to move it, like normal, the light will go red and i will be able to scratch, but when i release it, it stays red and does not play. how do i fix this?
