String ??? I have a Technics SL-MC50 and i have this string that came off of it from some where and the part that takes the CD out will not move does anyone know where this part goes? i have taken it to an Electronics Repair shop and they cant seem to figure it out either Any help appreciated Aaron

Yes, I have a soloution to this "String" problem.
Only because I have repaired mine twice already.
Unscrew the unit and take cover off,you will see the mangled "sting" wich is actually more like aviation cable takes some skill and a pair of steady small hands to fix.
you have to re-thread the wire back into position by hand on the left hand side you will see small wheels where the cable sit's in then rethread the changer post with 4 wheels thred it inside left bottom to outside left top, to over right top to inside bottom right.
I have temporarily fixed it. if you shake or mis handle the unit somehow it will fall off again!!
The reason for this is when the disc's change the guide wire will get looser with age and fall off.
the proper way to fix this is to take a pair of pliers and pull the string out the side where it is fastened pull it tighter to reduce the slack in the cable DO NOT over tighten or it wont change discs at all!!
keep playing around with the cable till it's re-threaded properly, you'll know when it's threaded right and be carfull not to bump it back off while screwing the cover back on. It's almost like re-threading an old movie projector.and if you feel daring you can try my permanant fix suggestion to tighten it some how with pliers to reduce the slack.
I almost threw my CD changer out when that happened i thought it could'nt be fixed but it is possible and it works fine.

I have not permanantly fixed it myself with pliers, but i'm pretty sure it would work, that way you wont have to rethread it everytime it falls off.
