how can i fix my nsm prestege two?

i have an nsm prestege two juckbox ,of which until today as played perfect for a number of years , it played a number of records and stuck on the begining of one ,i thought it was a bad record, but when i tried to eject i wouldnt , i managed to eject it and it went back to start , then when i selected annother record it tried to move then stopped, now the iject button works but to get it to play i have to stop it on eject on the record before it ejects fully, and there is a high pitch whine / and the lights dont go to standby. can any one give me a clue,
