Sony JA20ES minidisc.....needing repair?

Hi....I use this minidisc recorder, as an integral part of my studio set up....the drawer has decided not to open,.....this has happened in the past, and I have managed to take it into a dealer to be repaired.....now the same dealer is saying it's too old to be fixed......I really don't believe that, it's a decent bit of kit and very reliable apart from the drawer mechanism wearing out.....the rest is in great working order, and it has all the in's and out's a gal needs in her studio, including optical and coaxial....wouldn't sony still have parts for this?...I really don't want to replace it...any ideas?
Kind Regards
Tess
