Song DCR-TRV17E white tube fell out?!?! CL31L23 error message?

Hi, I have a Sony DCR-TRV17E and I began getting the C:32:23 error message...I googled it and everyone said that smacking the side of the camera worked, so I did this and it didn't work. I then read that there is this little white tube thing that goes on one of the rollers and someone else's had cracked and that was the problem. This little white tube had previously fallen off mine at the time my camera started having issues...I have kept it and I inserted it again...but it still beeps, my little tube also has a crack in it...has anyone had the same problem and what should I do (any free solutions would be better :P)
