The CD tray mechanism on my Alpha 5 has stopped working. I tried to
eject a CD this morning and, out of the blue, the tray made a
stuttering noise and got stuck halfway through. It's now stopped
responding completely.

I know very little about hifi equipment, so I'm not able to spot the
source of the problem. I took the top cover off to take a peek inside
and I noticed that, when I push the Load button, a pulley attached to
an elastic belt on the left of the tray starts to rotate, but the tray
itself does not move.

Is there any chance you could please give me some tips on where to
look? Any help would be much appreciated.

Also, until this gets fixed, would it cause further damage to the tray
if I opened and closed it manually? The CD player is part of a hifi
system I use to check final mixes in my recording studio, so I need to
use it on a regular basis.

Many thanks,
Milt
