I had the same issue with my Roy 1s when I got it, I went htrough overdrive and got the entire arm and shoulder assembly for 13 bucks shipped ems from japan, took a couple weeks but it was worth it. I have the 1j but honestly haven't taken it out of the box yet. 
 
I'm hoping that my tv max 1a and the vf1d don't have any issues.
