Hi all!
I have Sony CDX-51 changer and Sony XR-C300 control unit.
The problem is with my changer, when I select CD Play, control unit
displays RESET message.
Then I reset control unit and try again to play CD.
Display shows the message LOAD for a short period and again RESET.
The Unilink cable and control units are working, because I have tested
with another changer.
The problem is in changer I think.
Some notes about changer behavior:
- when I plug Unicable into it I hear some short moves in the mechanic
(init task)
- when I load magazine there are no reaction
(something like test used places in magazine)
- eject button sometime work from second try
- when I opened changer I have seen that socket for Unilink cable
was little disconnected from interface board with Audio signal
sockets.
I have fixed this but no success.

Can somebody to help me with any suggestions where is the trouble.

Thank you in advance!
