Hello
Would anybody know if there is  a technician or an audio repair company that would work on a Sony CDP- 557?
I am willing top spend some money.
Thank you for reading.

Hello.
Three things:
-button to open the disc drawer is broken
-sometimes the disc mechanism stops briefly during playing, so maybe new laser system or a belt?
-probably a good cleaning and check up

Thanks.
