CD wont play?

Hi,
I've got a Marantz CD63 KI Signature cd player that has performed faultlessly for more than 5 years. Took it to our holiday home to hook up to system there but it wont work!
What happens is it connects ok, draw opens, closes as normal, shows number of tracks etc but when you press "play" nothing happens. Have tried moving to different tracks, other cds etc but they just wont play.
As it cost over £500 some years ago, dont want to throw it away if there's likely to be a small repairable fault.
Any help?
