I haven't checked the size and it's not clear whether any take a knob, but something like these (Mouser)? http://www.taiwanalpha.com.tw/english2014/p_e_016.htm

I have a machine that was working until someone ‘over-adjusted’ the contrast knob and it now spins freely, and therefore doesn’t work. It’s not a mechanical issue with the screw and the knob, but rather inside the mechanism itself. I tried a quick scan of Digikey but I can’t find anything with remotely the same form factor. Wondering if anyone knows of a source for these, or has managed a repair with a substitute? Thanks for any guidance. Ian
