Pop the hood and check inside. Might be the tray mechanism gear which can be replaced at little cost. I have a friend who has done so with a older Rotel. I have had this problem with a Carver player. It did not use a gear, rather a belt which could not be replaced without removing and taking apart transport. Looked into replacing the entire transport but decided it was better to buy a newer used player.
As advised above, if this is player is aged it would not be worth putting much money into, better to get another.
