Reply to s4 right jog wheel

When I unpack my s4 box today, the left jogwheel was came off. I put it back following the video made by photojojo. After recalibrate both sides of the jogwheels, the left works well, but unfotunately the right one cannot scratch at all. When I try to scratch or scroll the track, it only makes a slight movement in the track. The pitchbend is also down in the right side. Anybody can help me??? I've recalibrated it for several times already...

I have a video here to describe the problem.
